Schunk to give MACH 2016 debut to new lines

As well as the new products that will have received their World Premiere at the recent EMO exhibition, Schunk will be drawing customers attention to the latest interfaces available for the Schunk TRIBOS system. Developed to improve surface finishes and tool service lives, the innovative TRIBOS system and its new interfaces will deliver a higher level of standardisation for precision tool holding. Some of these micro machining interfaces are now available with the TRIBOS RM and TRIBOS MINI ranges.

The TRIBOS-Mini that has been designed for high-speed micro applications can now be integrated with a high-speed HSK-E 20 spindle interface. The clamping technology experts at Schunk believe this newly standardised interface is superior to many short taper interfaces due to its accuracy at high speeds. In addition, it needs much less space compared with the HSK-E 25 interface. Schunk has designed the robust TRIBOS-RM with an extended L1 dimension of 78mm especially for high-efficiency 5-axes machining.

In order to allow precision machining of hard-to-reach areas, the mount can also be combined with the standardised TRIBOS-SVL tool extension with adaptations for HSK-A 32, HSK-A 40, HSK-E 32 and HSK-E 40 interfaces. In addition, Schunk has expanded its range in such a way that many of the previous special products will now be included in the standard catalogue. For example, TRIBOS-Mini will be standardised with ø 1, 1.5, 2, 3, 4, 6mm and 1/8 inch. TRIBOS-RM with ø 3, 4, 6, 8, 10, 12mm and 1/8 inch. In addition to the HSK-A 25, -A 32, -A 40, -E 25, -E 32, -E 40 interfaces that are already available, both mounts will also be available for HSK-E 20, HSK-F 32 as well as for BT 30 and SK 30. These units from Schunk are part of the world's most comprehensive programs for high-precision tool clamping and can now be manually actuated via the SVP Mini and SVP-RM devices, something that will be of great interest at MACH 2016.

In addition, Schunk will be keen to emphasise the benefits of its TENDO E Compact hydraulic expansion toolholder at MACH 2016. Capable of reducing set-up times by up to 60 per cent while generating 2000Nm of torque, the TENDO E Compact delivers micron precision for a host of machining applications. With this precision toolholder, even demanding applications with tight tolerances on the form, position and surface finish can be rapidly and reliably machined.

SPM Plus 138 fixture membrane

Another product that will be of interest at the UK's showpiece event will be the innovative SPM Plus 138 fixture membrane. Manufactured from aluminium, the SPM Plus provides the clamping of a multitude of geometries from all sides with its innovative pull-down effect. Firstly, a 0.5mm high tuning ring is inserted between the quick-change pallet module and the fixture membrane, and then the exact workpiece geometry is milled according to the blank on the fixture's clamping surface. Once prepared and the tuning ring removed, the workpieces can be inserted within seconds and the complete circumference be clamped by locking the VERO-S module. This in turn deforms the fixture membrane to provide the clamping.

Since the whole process is carried out within the elastic range of aluminium, the clamping operation can be repeated several thousand times. In contrast to conventional clamping blocks, the clamping force of this clamping method is carried out at the circumference of the whole workpiece contour and not just along an axis. Due to the clamping depth of only a few millimetres, the workpiece is fully accessible from five sides. The fixture membrane can be located on the quick-change pallet module with a repeat accuracy of less than 0.01mm.
