A system to enable surface grinding of a wide range ofmaterials from magnetic materials to such non-magnetic
materials as aluminum, stainless steel and ceramic.
［Features］■A wide variety of workpieces!

Workpieces of such non-magnetic materials as plastic, aluminum, stainless steel, ceramic and glassthat are diﬃcult to hold and secure with conventional chucks can be secured easily. ※In particular, this system is most suitable for holding small workpieces that cannot be held bymagnetic chucks.
Also, negative impact on accuracy due to warping of workpieces, which is unavoidable whenmechanical clamps are used, has been eliminated.
It cannot be used with the following workpieces in some cases:
・Workpieces having abrasive-like surface (e.g. plaster)・Workpieces warped largely (more than 0.5 mm)・Thin (less than 1.0 mm) workpieces such as stainless steel that tend to be distorted bygrinding heat・Some resins such as Teﬂon

PRB-2050A <Chuck part>■Easy installation

The main unit can be installed on a machine by use of T-slots. Also since its mounting face ismade of iron, it can easily be mounted on your magnetic chuck.

■A remote control box included!

BLOCKS
FOR MCA remote control box for controlling the chuck unit comes as a standard
accessory, which can be installed in an easy-to-operate place.
Operation box size: Width 80 × height 110 × depth 50 mm.

The wax used with this system is susceptible to impact and therefore
cannot be used for cutting as a rule. In dry operations, the temperatureof workpieces rises to melt the wax and therefore, it cannot be used.

materials and sizes of workpieces and grinding environment such as machines.

For evaluation of this system, preliminary fixing tests are necessary. Please contact KANETEC sales office in charge of you and provide workpiece samples.
