Grinding
Walter M4000 - High performance made universal
M4000 is the universal system for all users who want to have as many options as possible when milling. The M4000 range can master all machining tasks with one type of indexable insert. Whether used in shoulder milling cutters, high-feed milling cutters, face milling cutters, chamfer milling cutters, T-slot milling cutters, porcupine milling cutters or routing cutters, the square system inserts can be used across the entire M4000 range. For routing cutters and porcupine milling cutters, the range also has an additional rhombic indexable insert.
Up grinding versus down grinding
The Grinding Doc dispels the myth that switching from up grinding to down grinding eliminates burn and cuts wheel wear in half.
