SPK-CUTTING TOOL DIVISION ADDED VALUE TECHNOLOGY APPLICATION NEW MILLING CUTTER GENERATION High Speed Roughing and Finishing

TECHNOLOGY APPLICATION ADDED VALUE Achieving the optimal machining of a workpiece is no longer solely dependent on the cutting process. Increasing technological and economical challenges require highly efficient machining processes. To this end, we have developed the programme “SPK+ - The Productivity Experts” with the formula: tool + technology + application = increased productivity with lower costs. It has already been shown that the formula means a boost in productivity for our customers in many specific applications. In the future, we will draw attention to this by placing a...

PMK - High Speed Roughing and Finishing The PMK face milling cutter system is ideally suited for the rough milling and finishing of GJL (grey cast iron) and GJS (ductile cast iron) materials. These milling cutters work with an approach angle of 88°. FINISHING OPERATIONS USING PMK In order to attain outstanding surface qualities during finishing, the PMK series has been fitted with insert seatings that can be set in the Z-direction. This setting option allows users to pre-set the speciallydeveloped broad finishing inserts in the µm range. The inserts in the fixed insert seating take over the...
