Tooling systems maker BIG KAISER has introduced a new modular round chamfering tool called the R-Cutter CKB Type. The R-Cutter CKB3 & CKB5 is an ultra-high feed front and back radius chamfering mill which features high rake angles designed to reduce cutting resistance and minimize burr generation.

In engineering this tool, BIG KAISER wanted to find a way to improve upon the sharpness of their previous insert designs. To this end, the new cutter features a unique insert geometry. The four-insert design is built to cut in tighter spaces and at higher feed rates.

 The CKB connection is equipped with a floating drive pin which engages on both sides into respective pockets in the mating part. The tapers on the pins and the angles on the pockets are engineered to permit an automatic balancing of the two resulting torsional forces.

 Additionally, the CKB connection allows for an array of standard shanks and extensions to be adapted with the heads to create “custom” tools to extend over 16 inches, maintaining damping near the cutting edge and managing vibration in long-overhang setups.

 BIG KAISER is a member of the BIG DAISHOWA Group (Osaka, Japan), with manufacturing facilities in North America, Europe and Asia.
