Milling Cutters

High-speed electric spindle demo with micro tool

When considering options for speed, NSK America Corp. and OSG USA Inc. teamed up to highlight the benefits of proper speed applied to high-quality tooling. For the project, they machined their respective company logos onto a coin to showcase the intricate geometries and engravings that are possible with microtooling. They used a window machining process, along with NSK America’s HES510-CAT50 electric spindle and OSG USA’s AE-LNBD-N 1 mm long-neck, ballnose endmill, to achieve an ultrafine surface finish.

DoFeedTri High-Feed Milling Cutter

Ramping down, the cutter first bottom-cuts the surface with the leading insert, then further cuts the same surface with its trailing insert. DoFeedTri inserts are designed with a long “inner” cutting edge that can bottom-cut more material than conventional milling inserts when trailing the leading insert during ramp down operations. This makes DoFeedTri a perfect tool for productive ramp down operations. 

High Feed Square Cut Size 14 Milling Systems

Not only does this solution make it easier to machine sticky materials, but it is designed for easy, ergonomic indexing and the pocket and screw designs simplify positioning. The cutters themselves feature a new environmentally friendly coating and their outstanding high feed milling performance reduces the amount of power used in roughing. Yet another step in the right direction for Seco Tools to continue their journey to create more environmentally sustainable manufacturing and machining solutions.
