Walter's M4791 Routing Cutter Can Be Used on Lathes and Machining Centers
Walter USA has expanded its M4000 milling cutter line with the M4791, a routing cutter capable of plunging in solid material and producing a true flat bottom. The tool is applicable in both lathes and machining centers.
The M4000 milling series is designed such that the same indexable insert (available in TTS and TTG) can be used for all milling cutters. M4791 tools are offered in diameters of 0.75", 1.00", 1.25" and 1.50" with Weldon shanks for secure clamping. A variety of inserts are available with geometries of A57, D51, D57, F57 and G88.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
The right choices in tooling and technique can optimize the thread turning process.
