Our passion:
Complete clamping systems for machine tools
OTT-JAKOB develops complete tool clamping systems for machine tools. From the clamping unit to the rotary union, we manufacture all components ourselves right here in Lengenwang, Germany. With our decades of experience and our comprehensive user know-how, we offer excellent technical solutions that function reliably and guarantee high product and service quality for years to come. We call this "Long-life Clamping Technology". For you, as our customer, the purchase of a complete tool clamping system from OTT-JAKOB offers several advantages.
- All components are optimally coordinated with each other.
- Through the constant exchange of knowledge with leading universities, we are always at the cutting edge of technology and able to translate technological challenges into innovative product solutions.
- Our employees and suppliers are committed to strict quality targets through consistent quality management. Through continuous improvement processes, we constantly set ourselves to higher standards.
- Seamless quality controls and a 100% final inspection of the assemblies guarantee the highest delivery quality.
- Whether during commissioning or in the rare event of a defect: Our in-house service department is always here to help you after the initial purchase.
Individual clamping systems:
Made to measure
OTT-JAKOB Spanntechnik GmbH has been an expert
in the field of tool clamping technology for
almost 50 years. Over the past decades, we have
already designed thousands of individual tool
clamping systems for a wide range of
applications - and the number continues to
grow.
Because of our experience, OTT-JAKOB knows
exactly what is required of a tool clamping
system: high pull-in forces, safe clamping, fast
tool changes and a long service life are
essential for our products. In addition, we
offer constant condition monitoring to take into
account the ever increasing levels of
automation.
OTT-JAKOB consistently relies on a
customer-specific design of its tool clamping
systems. Like a tailor-made suit, OTT-JAKOB
designs tool clamping systems that are
individually adapted to the spindle and its
application.
"My team and I will be happy to advise you on the composition of an individual clamping system and the selection of suitable assistance systems."

Fastest clamping system
The miniaturisation trend for electronic components is ongoing and is being driven by developments in the field of mobile devices such as smartphones. OTT-JAKOB clamping systems designed for maximum RPMs are used in specially developed machines in order to drill the circuit boards.

Strongest clamping system
Aerospace components that are subjected to high mechanical stresses, for example, undercarriages, are made of titanium or titanium alloys in modern planes. High torque is required to machine titanium due to its specific properties. High pull-in forces are needed to connect the tool holder to the spindle securely whilst absorbing the powerful forces of the machining process. Our strongest clamping systems are designed to machine difficult materials and are installed in machines and spindles that are used to manufacture aerospace components.

Shortest clamping system
Many dental surgeries use a manufacturing solution that can produce replacement teeth, largely eliminating the need for castings. An intraoral camera is used to measure the tooth precisely using digital photos. The replacement tooth is then designed to fit perfectly on a computer and produced by an integrated machine tool. Fitted with our shortest clamping systems, the end product is milled from a ceramic block in minutes. The replacement tooth can often be fitted in the same session.

Longest clamping system
The growing use of wind power as a renewable source of electricity has led to the construction of increasingly large wind turbines. In offshore wind farms, turbine blade lengths of 80 m or more are not uncommon. The enormous forces generated by these blades have to be absorbed by the hubs and transferred to the gears along with the generator. Once cast, large machining and drilling centres are required to machine these huge hubs. These machines are fitted with our longest clamping systems. This makes it possible to reach and produce the necessary holes, even the internal ones.
