BIG Kaiser Precision Tooling Inc. introduced the C-Cutter Mini, an ultra high feed chamfer mill.
The C-Cutter Mini’s compact design reduces the cutting diameter to the lowest limit, helping to achieve higher spindle speeds and feeds. In addition, it delivers multi-functional cutting, including chamfering, back chamfering and face milling.
Its high speed back chamfering capability reduces hand deburring, and face milling is possible with a 45 degree chamfering type with .394” square insert.The C-Cutter Mini is available in single insert and four-insert designs. The single insert design utilizes a small 0.197” square insert with four cutting edges for smaller 45 degree chamfers and a slightly larger insert for 30 and 60 degree chamfers.
The four-insert design permits 45 degree chamfering for diameters .433”-1.654”. Its “triple effect” design combines four inserts for higher feed rates, a compact diameter for increased spindle speeds, and a new wear resistant multi layer PVD coating for increased cutting speeds.
According to the company's press release, in one example, these factors helped the four-insert C-Cutter Mini achieve 13 times better cutting efficiency than a competitor’s three-insert cutter.
