The Tribos Mini, designed for high-speed micro applications, can now be integrated into a high-speed HSK-E 20 spindle interface. Schunk believes that this newly standardized interface is superior to many short taper interfaces due to its accuracy at high speeds. In addition, it needs much less space than the HSK-E 25 interface. Another toolholder, the Tribos-RM, offers an extended L1 dimension of 78 mm especially for 5-axis machining.
For 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 solutions will now be included in the standard catalogue. For example, Tribos-Mini will be standardized in seven diameter sizes from 1 - 6 mm; Tribos-RM similarly in seven sizes from 3 - 12 mm. 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 can now be manually clamped by the SVP Mini and SVP-RM devices.
Also, Schunk is emphasising the benefits of its Tendo E compact hydraulic expansion toolholder at MACH 2016. It is said to be capable of reducing set-up times by up to 60% but can generate 2,000 Nm of torque.
Another featured product is the SPM Plus 138 fixture membrane that inserts into the Vero-S zero point workholding system. Manufactured from aluminium, the SPM Plus provides the clamping of a multitude of geometries from all sides, since the exact workpiece geometry is milled into the fixture’s clamping surface. Once prepared, the workpieces can be inserted within seconds. 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 millimeters, 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 0.01 mm.
