The ACS axial clamp from OTT-JAKOB was developed for use in rotating processes. It actuates on an axis which makes ACS the ideal clamping unit for grinding applications The ACS axial clamp from OTT-JAKOB was developed for use in rotating processes.

The CTC manual clamping unit was designed for rotating applications and is the only quick-clamping system available on the market which is actuated via the coolant hole. The tool can easily be mounted using a torque wrench from the front of the polygonal profile. Thanks to clamping through spring, little actuating torque is required. The CTC manual clamping unit was designed for rotating applications and is the only quick-clamping system available on the market which is actuated via the coolant hole.

HSK has already become a standard interface in rotating processes. To make it possible to use it in static operations in turning machines, OTT-JAKOB – inspired after joining the HSK-T working group – developed the QCS manual clamping unit. The quick-change clamping system (QCS), designed especially for manual quick changes with HSK holders, is compatible with all HSK standards (A, B, E, F, T). It is not necessary to change the turret. The generation of force through Archimedean spirals produces a self-locking effect. Easy to operate with a spanner, it guarantees quick and easy tool changes. QCS can be used with and without coolant. It is particularly effective if combined with an HSK-T tool and an HSK-T holder. This is due to the high positioning accuracy resulting from the limited tolerance of the HSK-T driver grooves. The quick-change clamping system (QCS), designed especially for manual quick changes with HSK holders, is compatible with all HSK standards (A, B, E, F, T).

The SVC range is used in static machining. With its short projecting length, SVC has more space for the workpiece and a larger flight radius. The built-in seal effectively protects the clamping area from becoming flooded with coolant. Little actuating torque is required to reach high clamping forces. A conventional hexagon socket wrench is required to change tools. The SVC range is used in static machining.

For the shortest possible spindle lengths, shorter variants of many Type B clamping units are also available. For the shortest possible spindle lengths, shorter variants of many Type B clamping units are also available.

Type C HSK generates extremely short tool-changing times. The built-in holding function minimises waiting time during the tool-changing process. Our high-quality, optimised DLC coating also gives it a long life span. Type C HSK generates extremely short tool-changing times.

Based on Type B, this clamping unit provides an even higher transmission ratio with an identical internal contour.

Type K HSK is the most cost-efficient solution in the range of OTT-JAKOB HSK-Clamping-Units. A solid basic variant, it is particularly suited for standard applications. Its high-quality coating gives it a long life span. Type K HSK is the most cost-efficient solution in the range of OTT-JAKOB HSK-Clamping-Units.

The high-performance KM4X interface was developed to meet the specific requirements of working with hard-to-machine materials such as titanium alloys. KM4X allows a machine tool to utilise its full power potential in challenging turning and milling projects. Tools are clamped by four spheres which are forced radially outwards during the clamping process. Three contact surfaces deliver maximum stability and optimally distribute the clamping force, resulting in outstanding resistance to bending moments. The clamping units for the KM4X interface are the product of an exclusive development partnership between OTT-JAKOB and Kennametal. Our range of modular clamping systems can be used to configure a complete system. KM and KM4X adapters are available for the pull-in force measurement system The high-performance KM4X interface was developed to meet the specific requirements of working with hard-to-machine materials such as titanium alloys.

The polygon shank cone is a powerful interface that has proven its effectiveness especially in multitask machines. Launched on the market in 1990 under the name Coromant CAPTO, it was internationally standardised under ISO 26623 after the patent expired. The main feature of the polygon shank cone is its unique tapered polygonal shape which, due to its self-centring properties, effectively prevents axial and radial play. The face contact accurately defines the position of the tool in the holder and produces excellent repeat accuracy. The polygonal shank cone is therefore ideal for high-precision applications. The PSC interface features excellent stiffness due to the large taper diameter. Additionally, the balanced distribution of torque over the polygon surface generates maximum stability. The polygon shank cone is a powerful interface that has proven its effectiveness especially in multitask machines.

The steep taper is the original tool interface and continues to see frequent use in the machine tool industry. Steep taper technology has proven itself for decades and, in spite of the increasingly widespread use of HSK interfaces, remains a practical solution for standard machine tools. Universal spindle contour Thanks to the spindle inside contour developed by OTT-JAKOB, various standards of tool can be used in the same spindle. The universal spindle contour is compatible with all conventional tool standards. - DIN 2080 (OTT-Rille) - DIN 69871/69872 (ISO 7388/1/2 Type A) - ANSI B5.50-1978 (ISO 7388/1/2 Type B) - MAS 403-1982 BT/PT1 (30°) - MAS 403-1982 BT/PT2 (45°) The steep taper is the original tool interface and continues to see frequent use in the machine tool industry.

Las nuevas interfaces HSK 15, 16 y 20 requieren un dispositivo especialmente pequeño para medir la fuerza de tracción. Por eso hemos desarrollado el compacto Power-Check Micro especialmente para estas pequeñas interfaces. Los valores medidos se envían de forma inalámbrica a un ordenador a través de la memoria USB suministrada. Translated with DeepL
