The focus of this year’s EMO appearance of OTT-JAKOB was an all-in-one rotary union which combines three functions in one unit.
The 2KA-ME rotary union combines the proven dual-passage technology for hydraulic unclamping and integrated media transfer with state-of-the-art clamping condition sensors. The distance measurement system records the exact position of the drawbar shaft, from which the current tool position can be derived with high precision. An analog transmission of measured values (mA or V) is possible as well as an evaluation directly in the integrated electronics with output of the clamping states “unclamped”, “tool clamped” and “clamped without tool” in digital form.
Pre-assembled in the rotary union to save space, 2KA-ME represents a weight-reduced alternative to conventional solutions with signal rings. The monitoring function can be integrated in all OTT-JAKOB dual-passage rotary unions. The sensor system used is a tried and tested development by OTT-JAKOB, which has already proven its reliability in use in MSU unclamping units.
With 2KA-ME OTT-JAKOB offers a ready-to-use solution. The system can already be preconfigured during spindle production using the Windows application MSU Configurator. This facilitates on-site setup while avoiding configuration errors and increases service friendliness. There is no need for time-consuming mechanical adjustment work.
Regular checks of the tool pull force are essential, because the machining quality is fixed as soon as the tool is pulled into the spindle taper. If the clamping force required for this is insufficient, vibrations are likely to occur, which in turn will result in chatter marks on the surface of the workpiece.
With the Power-Check Magazine, OTT-JAKOB highlighted a high-precision testing device for checking the clamping force condition at its booth. Designed for permanent use in the tool magazine, the Power-Check Magazine has a gripper groove and a long-term battery, which enables a mains-independent operation for up to 30,000 measurements. Thanks to a self-activation mechanism, the measurement starts automatically during the exchanging process.
The Power-Check Magazine is available for all common sizes and variants of the interfaces SK, HSK, PSC and KM (KennametalTM). For data acquisition there are three options to choose from: the Power Monitor with a display, the USB radio stick to transmit the values to a PC and the RS485 bus antenna for data transfer to the machine control system. The latter offers special advantages with regard to data output. Since this is an in-house development of OTT-JAKOB, it is possible to integrate interfaces for an analog and/or digital output.
March 1, 2018 marked the 25th anniversary of the founding of OTT-JAKOB. On the occasion of this event, the company held a major anniversary celebration on September 14 and 16. Employees and former staff celebrated together with their families at the company headquarters in Lengenwang under the motto “When passion turns into performance”.
The celebrations began on Friday with a festive evening. After being welcomed by company founder Ludwig Jakob and managing director Frank Jakob, the more than 200 employees were surprised by a diverse supporting programme of show acts, hands-on activities and live music.
On Sunday the employees´ families were also invited to join the celebrations. On this day, the company grounds were transformed into a small amusement park with numerous attractions. In addition, the doors were open for a factory tour so that the families could take a look behind the scenes of the technology company.
The origins of OTT-JAKOB Spanntechnik GmbH go back to the Institute of Mathematics and Mechanics A. Ott, founded in 1873 in Kempten, which initially specialised in the manufacture of mathematical and hydrometric instruments. The product range was constantly developed further and extended to tool clamping systems in the 1970s. The clamping technology division was spun off 25 years ago and since then has operated as an independent company under the name OTT-JAKOB.
From September 10 to 15, the 32nd IMTS, the largest trade show for manufacturing technology in North America, will take place in Chicago. In the run-up to this year’s edition, the organisers arranged the IMTS Exhibitor Product Innovation Competition to recognise the most innovative exhibits. The winners were announced at the beginning of August. OTT-JAKOB took second place with the Power-Check Magazine pull force measuring device.
Numerous exhibitors had applied for the prize with their developments. A jury consisting of members of the Association for Manufacturing Technology (AMT) chose the three most innovative solutions. The entries were evaluated according to technical and economic criteria, including degree of technological innovation, cost efficiency and benefits for the industry, environment and society.
Designed for fully automated use in the tool magazine, Power-Check Magazine is predestined for integration in a Smart Factory environment. “The OTT-JAKOB Power-Check Magazine is a major step towards the implementation of Industry 4.0 in the field of production and helps to achieve highest quality standards.”, says Josef Greif, R & D Director at OTT-JAKOB.Click here to watch the interview with IMTS TV.
The time has come for the market launch of the turret interface pti (polygonal turning interface) with the first size pti65. The REKUNORM project answers the last open questions in the development of pti. On May 8, about 50 experts met for an information event in Lengenwang at the headquarters of the clamping technology specialist OTT-JAKOB.
The REKUNORM project group, chaired by Dr. Dietrich Lembke, chairman of the DIN standards committee, presented the current state of development of the project. The main objectives of REKUNORM are the development of a uniform coupling for driven tools and the development of a standard proposal for shank, holder and coupling. While work on the coupling is still in progress, the two main parts of the future standard (shaft and holder) can already be submitted as a draft standard in October 2018 due to the advanced development work.
The project partners pursue independent development tasks in their respective fields and transfer the results into a joint standard proposal. The REKUNORM Group, consisting of OTT-JAKOB, the revolver manufacturer Sauter, the tool holder manufacturer WTO and the lathe manufacturer Weisser as well as the WZL of RWTH Aachen also presented the progress of the individual sub-projects in Lengenwang. The result is a tool interface with a planar system and an octagonal conical polygon shank (pti). After a first development project (REVOSIT) has already laid the foundations for the pti65 size, this has now been completed within the framework of a series and completed with pti54 and pti42 by two further sizes.
The objective of OTT-JAKOB is the development and production of a turret clamping system for quick change of tool holders with polygonal shank. With the introduced powerful pti clamping system, essential prerequisites have been created for the pti interface to find its way into industry.
The tool clamping system manufacturer OTT-JAKOB celebrates its 25th anniversary in 2018. On March 1,1993, the tool clamping technology division of OTT-Maschinentechnik was spun off and integrated into the JAKOB Group by the father of today’s managing director Frank Jakob as an independent company under the name of OTT-JAKOB Spanntechnik.
The roots of the family-owned company, which is located in the Allgäu region, go back to 1873, when Albert Ott founded an institute of mathematics and mechanics. The original core business was the production of mathematical and hydrometric instruments. The company entered the mechanical engineering sector in 1948 with the production of cross-winding machines for the textile industry.
In the early 1970s, the mechanical engineering sector was expanded to include machine tool technology and the company began producing tool changers and clamping systems. Today, OTT-JAKOB focuses exclusively on the development and manufacture of tool clamping systems and mechatronic monitoring solutions for machine tools and is one of the key players in this market worldwide.
On 18 September, during the world’s leading metalworking exhibition EMO, the German MM MaschinenMarkt magazine has granted the MM Award for the sixth time. With the prize the magazine honoured the industry’s most innovative exhibits. In the category “clamping devices” JAKOB Antriebstechnik GmbH, a JAKOB Group company, was able to persuade the judges with its digital clamping force device “Force Monitoring System PAD” and take home the prize.
The award is also an acknowledgement of the innovativeness of JAKOB’s affiliated company OTT-JAKOB. As project partner, the tool clamping technology manufacturer has been decisively involved in engineering FMS PAD by developing the entire electronics for the novel monitoring system. The company was able to apply its many years of experiences in R&D projects in the field of sensor based monitoring technologies and transfer its know-how from tool clamping technology to workpiece clamping technology.
FMS PAD monitors the clamping force during all operating states at large machine tools and is an important step towards a connected production environment. “The award confirms that we are on the success track in terms of the Industry 4.0 machine tool with our new development”, said Dr. Arno Wörn, head of development at JAKOB Antriebstechnik. Together with Dr. Stefan Bonerz, technology manager at OTT-JAKOB Spanntechnik, Mr. Wörn accepted the MM Award in Hanover.

With their multi-sensor unclamping unit, OTT-JAKOB showcased the latest addition to their portfolio in sensor-based assistance systems at the EMO Hanover. The sensor system introduced as MSU is an innovative Plug & Play Monitoring solution that groups up to three control functions into one unit: monitoring of the position of the drawbar shaft, detection of the position of the release piston and optimum leakage detection. MSU can be integrated into virtually all OTT-JAKOB unclamp units and be adapted to special solutions.
In the field of manual clamping technology OTT-JAKOB informed about the new research project REKUNORM which was launched for the EMO. REKUNORM is the follow-up project to REVOSIT, from which the standardised pti turret interface (polygonal turning interface) arose. As a result of the existing diversity of couplings on the market, the main objective of REKUNORM is to develop a standardised coupling for driven tools in turret lathes.
The Power-Check 2 pull-in-force measurement device has been design-optimised thanks to a number of further developments. Among the most important measures is the changed locking function of the adjusting sleeve that now operates without bores on the plane surface; this, in turn, enabled additional implementation of sealing of the sleeve and the force sensor. Due to the changes made, OTT-JAKOB has laid the foundations for achieving the IP67 protection class, which is, among other things, equivalent to protection against penetration of water when temporarily immersed.
The new OTT-JAKOB product catalogue offers comprehensive information on automatic tool clamping and serves as a tool for design engineers to plan their projects and configure a clamping system.
On 166 pages, OTT-JAKOB presents a selection of its wide range of products and as an expert in individual solutions, focuses on components for the most common applications. Following the modular setup of the clamping systems, the product section is structured into four main chapters: grippers, pulling heads, unclamping units and rotary unions. This is rounded off by selected reference clamping systems with corresponding sample applications and accessories.
The catalogue contains detailed technical specifications and order information, as well as dimension drawings. Tables provide an extensive overview of the wide range of products. An easy to grasp colour coding system ensures quick orientation. For the new edition of its catalogue, OTT-JAKOB has also developed a concept which gradually guides customers to the individual order code of their desired configuration.
The new OTT-JAKOB catalogue is available in German and English.
On 1 June 2017, a change at the top of the OTT-JAKOB sales department will take place. The long-time Sales Director Hubert Sykora will retire after 47 years with the company. He will be followed by Hans Leidl.
With Leidl, the clamping technology specialist was able to acquire an experienced manager within the company’s own ranks as successor to Sykora. Having worked at OTT-JAKOB for 20 years, Leidl possesses in-depth knowledge of the company and industry. Since 1997 he has led the service team within the sales department and already has built a reputation among customers as a reliable and competent contact person.
From his new position, Hans Leidl will manage all global sales and service activities and report directly to the Managing Director. In the course of the personnel changes, the long-time sales representative Roland Theurer was appointed Deputy Head of Sales. Alexander Heupel, previous Deputy Head of Service, takes over the role of Head of Service.
As an internationally operating company, OTT-JAKOB has built a network of qualified specialists over the years in order to ensure reliable service and optimal support on site. With Fischer Spindle Technology, the Allgäu based company managed to acquire another strong partner for the Russian market.
Located in Novosibirsk, Fischer Spindle Technology is a subsidiary of the Swiss spindle manufacturer Fischer AG, a long-time customer of OTT-JAKOB. The Siberian location was founded in 2010 as spindle service center of the Fischer Spindle Group AG.
Hubert Sykora (Sales Director) and Hans Leidl (Head of Service) have laid the foundation for the future cooperation with a trip to Novosibirsk. With an extensive training, Fischer Spindle Technology got prepared intensely for its upcoming tasks as a representation of OTT-JAKOB.

In September, OTT-JAKOB presented itself at two top-class events and had the chance to showcase its product solutions to an international audience. At IMTS in Chicago and AMB in Stuttgart, the company informed about its portfolio of products and services.
The “International exhibition for metal working” (AMB) ranks among the world’s leading exhibitions in the mechanical engineering industry. Around 90,000 visitors came to Stuttgart to catch up on the latest market trends. At the OTT-JAKOB booth everything revolved around automatic complete systems, manual clamping technology and intelligent condition monitoring technologies.
Besides a selection of the current product range, exhibits included a number of new innovations and further developments. This year’s AMB highlights were a clamping system equipped with a FRP spring, as well as the rotary union 2K-GDSD-CO2, which has been specifically designed for cryogenic machining. Furthermore, OTT-JAKOB introduced a complete system solution for the high-performance interface KM4XTM.
At the IMTS in Chicago, OTT-JAKOB was represented by its long-term partner AME, which is celebrating its 50th anniversary this year. With about 2,000 exhibitors and more than 100,000 visitors, IMTS once more confirmed its status as the largest manufacturing technology trade show in North America.
For the eleventh time, the Institute for Machine Tools and Factory Management hosted the machine tool congress “Berliner Runde”. Around one hundred representatives from industry and science met for knowledge exchange on 3 and 4 March at the Berlin Center for Production Technology.
Participants had the chance to attend a top-class event featuring presentations by renowned speakers of the machine tools industry as well as a parallel held exhibition. Current and future developments in machine tool construction were presented on this year’s key topic “Sustainability, productivity and quality in the production through utilisation of sensors and actuators”.
OTT-JAKOB participated at the two-day event with a presentation on “Condition monitoring in motor spindles”. Technology Manager Dr Stefan Bonerz discussed how the use of sensor based monitoring systems helps to identify failure potential of clamping systems components early. Information on the complete product range of OTT-JAKOB was provided at the exhibition booth.
On 18 and 19 November, the 15th Machining Innovations Conference for Aerospace Industry (MIC) took place at the Hanover Centre for Production Technology. MIC is an internationally valued forum with more than 200 experts from science and industry participating each year.
The conference was hosted by the Machining Innovations Network e. V. in cooperation with the Institute of Production Engineering and Machine Tools. Focus of the event have been presentations by speakers of renowned companies about current trends, experiences and research results on “Production technologies in aerospace Industry”.
Dr. Stefan Bonerz, Technology Manager at OTT-JAKOB Spanntechnik GmbH, discussed the flush fitting control in his speech with the title “Monitoring the quality of tool clamping in the tool interface”. At the booth of the parallel running exhibition, visitors had the opportunity to learn more about the OTT-JAKOB product range.
Since 2010, OTT-JAKOB has been on YouTube with an own channel. After an extensive rebranding in July 2015, the company launched a new channel to adapt its YouTube appearance to the new corporate identity. The new channel replaces the former one and serves as an information platform for customers and prospects.
The grand final of OTT-JAKOB´s exhibition year was the participation at the 2015 edition of the EMO in Milan, Italy. “Let’s build the future” was this year’s motto of the world’s leading metalworking fair, which attracted more than 155,000 visitors. OTT-JAKOB featured at its booth solutions for automatic and manual tool clamping as well as for Industry 4.0.
As a manufacturer of complete, automatic tool clamping units, the company placed special emphasis on the modularity of its clamping systems. The unique setup allows the combination of standard components with costumer-specific elements. Exhibits included the well-established interfaces SK, HSK and PSC (Coromant CAPTOTM), as well as the high performance interface KM4XTM, which was developed in exclusive collaboration with Kennametal. The manual clamping units of the series QCS for HSK and CTC / SVC for PSC have been on display, too.
In the field of the current industry’s key topic “Industrie 4.0”, OTT-JAKOB was showcasing its portfolio of assistance systems. With the development of intelligent monitoring technologies, the clamping technology specialist once again demonstrates its innovativeness. The product line built around the tool pull force device Power-Check 2 and the flange surface monitoring system PLANKO have been given special prominence at the booth.
The EMO was also the first public event, where OTT-JAKOB presented its new brand identity. After an extensive makeover, the company re-introduced the brand in July and uses the new visual appearance in all media since. The new slogan “Long-life Clamping Technology” concisely summarizes the essence of the brand.
From 14 to 18 September, the engineering fair MSV took place in Brno (Czech Republic). The 57th edition of the leading industrial fair in Central Europe offered its more than 1,500 exhibitors once again an ideal platform to present their products to the international engineering industry.
At the joint booth with JAKOB Antriebstechnik, OTT-JAKOB and its Czech representative Číhal s.r.o. displayed a selection of tool clamping solutions. The company focused on its core competencies with exhibits from its automatic and manual tool clamping range.
Over the duration of the trade fair, the OTT-JAKOB booth was continuously well frequented. The mainly Czech visitors showed great interest in the modular set up of OTT-JAKOB clamping systems and the numerous configuration possibilities. Moreover, there has been noticed an increased demand for rotary unions.
As in previous years, the high density of top-class exhibitors resulted in excellent visitor attendance. Particularly positive about the 2015 edition of the MSV was the large number of end-users visiting the event.
To ensure a high level of process reliability in machining, high-resolution sensors are necessary for monitoring the flange surface of the tool during rotation. These distance measurement sensors face a diverse and demanding range of requirements.
At EMO 2011, OTT-JAKOB presented its brand-new flange surface monitoring solution (working title ‘PLANKO’) based on ceramic resonators and waveguide structures which, in combination with radar electronic components, make it possible to precisely and reliably measure distances from 10 µm at turning speeds of up to 15,000 rpm.
This solution was further optimised in coordination with selected spindle and machine tool manufacturers. In the new sensor structure, the sensor path in the transition area is now replaced by a cable between the radial and axial holes. The critical machining dimensions of the deep, circular waveguides are consequently not necessary. The assembly process is also made easier, and the flexibility for various tool interfaces is ensured. The resonator is reduced to a minimum length and forms a compact electronics module with the cable and the connector, which fits perfectly into the prefabricated installation hole. The rotor signal is coupled by means of an antenna, while the other high-functioning electronics have been further miniaturised and can be integrated around the spindle nose.
There is more to OTT-JAKOB than meets the eye. Now and in the future. The technology leader OTT-JAKOB will demonstrate this from now on with its own technology label.
What long-life clamping technology means for our customers:
Innovative technologies which go far beyond mere clamping systems and which guarantee maximum safety and precision in the long term.
Top quality – this goes not only for our own products, but also for the machining process of the machine tool and its end product.
Maximum passion – during development, over the entire life cycles of our products and in personal service for years to come.
