Inserts suit hard-turning applications.

Press Release Summary:

Designed to replace PCBN mini-tip inserts, full-top PCBN MiniCerts remove material without risk of mini-tip melt-off due to running dry or fracture due to interrupted cuts. Units are suited for hard-turning of tool steels ranging from 45-65 Rc as well as Class 20-40 cast irons. Enabling machining speeds up to 600 sfm at 65 Rc or 3,000 sfm on cast irons, inserts produce chip loads to .010 ipr, depth of cut to .045 in., and finishes to less than 5 Ra.

Georgia Superabrasive Tooling Introduces MiniCerts

MiniCerts are a New Industry Product to replace Mini Tips.

A Cost Effective Alternative to PCBN or PCD Mini-tips (Still Grinding or using Mini Tips?)

August 1, 2007 -- Snellville, Georgia - A revolutionary and more cost effective product to replace Mini Tips. MiniCerts provide a greater depth of cut and feed rates, when compared to Mini Tips.

Georgia Superabrasive has created a new cartridge tool holding system which provides an economical way to take advantage of the enhanced performance characteristics of full-top PCBN cutting tools for hard turning applications. Increase productivity by replacing your PCBN mini-tip inserts with full-top PCBN - remove more material without the risk of mini-tip melt-off due to running dry or Fracture due to Interrupted cuts. Machine through interrupted cuts on gears and splines with no risk of mini-tip destruction.

GST's full-top CBN inserts are ideal for the hard-turning of tool steels 45Rc to 65Rc+ Class 20 to 40 Cast Irons. Our inserts allow machining speeds up to 600+ SFM @65Rc or 3000SFM on Cast Irons, chip loads to .010 IPR, with depth of cut to .045" And finishes to <5Ra.

The key to full-top CBN inserts being the best choice for hard-turning applications is its enhanced performance due to superior strength (no brazed joint), sharp edges and fine grain CBN. These unique properties enable higher machining rates, faster metal removal, easy chip control, as well as the ability to finish components in one pass while retaining surface quality. Not only is machine productivity improved but full-top CBN inserts eliminate the problems of mini-tip melt off due to overheating and mini-tip destruction due to interrupted cuts.

Higher machine productivity translates directly into lower cost per part. Companies that currently use mini-tips for hard-turning or grinding operations to finish hardened parts can now realize an overall savings.
