By upgrading its master adaptor from HSK to Walter Capto, tool manufacturer Walter is launching a new system interface. The interface incorporates concealed balancing holes, which were previously on the outside of the tool.

This balanced construction created at the Walter factory also incorporates an integral chip hole. As a result, there is no longer any need for the user to drill this hole. It provides machine shops with the possibility of digital tool integration for automated tool management, for example. This is because users can save tool data such as dimensions by inserting a data chip into the tool ready for reading out when required, like for activities such as programming or archiving. Walter offers the modular adaptor (HA06-C and HA10-C) from HSK-A to Walter Capto with HSK-A 63 or HSK-A 100 interface in Capto sizes C3-C8.

End users will benefit from high levels of process reliability and precision as the adaptor is very rigid. A further advantage is precise repeat accuracy down to 2 µm during tool changes.

Inherent versatility makes the system suitable for all types of adaptors, such as Weldon, ER collets and hydraulic expansion chucks, or milling adaptors with arbors for milling and hole-making. The system is thus compatible with all kinds of machines, from machining centres through to multi-tasking machines.

Users of data storage devices can open up their entire range of tools with the master adaptor thanks to its suitability for use with all types of machine and machining operation.

A new range of electrically actuated swing clamps capable of generating high forces for securing workpieces during machining is now available from Roemheld UK. Manufactured by Roemheld’s German parent company alongside established pneumatically actuated variants, users can control the latest clamps individually or in multiples. The maintenance-free units are suitable for mounting vertically or horizontally, and work well as part of automated work-holding solutions.

Driven by a wear-resistant, brushless, 24 VDC motor via a gear and threaded spindle, the device requires only 3 mm of axial lift before the clamping arm swivels. According to the model in use, it rotates by either by 90 or 180°, clockwise or counter-clockwise. Other swing angles are available on request. The electronic control for the motor is built into the swing clamp housing and has its own 24 VDC/100 mA power supply.

Two variants of swing clamp are available, 1833 and 1835, the latter having a higher clamping force. For both models, which carry an IP67 ingress protection rating, users can adjust and monitor the force, its maximum value depending on the length of arm deployed. It takes approximately 3 seconds to secure or release a component. Should the power supply fail, there is no loss of clamping pressure.

During unclamping, the arm swings back to its starting position. Should it meet an obstruction during motion, in either direction, automatic and instantaneous motor switch-off protects the mechanism from overload.
