ETGplus CNC Tool and Cutter Grinder -

Information:

Economy Tool Grinder plus (ETGplus)
In addition to grinding end mills, step drills, reamers, form cutters, burrs, and shaper cutters, the ETGplus sharpens extended-length tools such as gun drills and gun reamers. Based on the ETG platform, Star added a direct-drive headstock and a wheel probe. We also made the headstock movable so you can grind tools up to 21" overall length.

ETG Performance Features

  • HSK Quick-Release Grinding Wheel Arbor allows wheel pack changes in under one minute while providing the necessary locating repeatability for off-line wheel dressing and wheel measuring.
  • HSK quick-release precision hydraulic chucks with sleeves is available for precision chucking of tools from 1/8 to 1-1/4 inch diameter range.
  • Cat 50 Collet Chuck and Collet Set is available for chucking tools from 1/8 to 1 inch diameter range.
  • PC-based Computer with Flat Panel Monitor instead of an industrial computer. The latest in personal computer technology provides the necessary speed for running 3D simulations at the machine and allows for quick and inexpensive upgrades.
  • Maximum HP available throughout entire RPM Range For fluting carbide, the ETG grinding spindles provide the same 10 horsepower at the lower RPM range of 1,900 as it does at the maximum speed of 10,000 RPM.
