Walter’s Helitronic Micro grinding machine combines linear technology and a 7-axis layout that optimizes the production grinding and regrinding of microtools, reports the company. The linear/direct drives allow travel speeds up to 2,000 ipm—30 percent faster than ballscrew machines. The Helitronic Micro grinds tools with diameters ranging from 0.02" to 0.50" and regrinds tools having diameters 0.1" and larger.

July 26, 2011—Operator Bill Schumack grinds a 420 stainless steel part on a Monza 410 centerless grinder. This is a good illustration of the centerless grinding configuration; namely that the part is not supported on centers, but is placed between the regulating wheel and grinding wheel. Also shown is a closeup of the centerless grinding process on another machine.
