High Precision Face Grooving System Designed for Large Diameter Twin-Cutter Boring Heads

BIG KAISER has released new insert holders for face grooving. The new accessories are specifically designed to fit the BIG KAISER large diameter Series 318 and Series 319 SW twin-cutter boring heads for ultimate system flexibility.

The new face grooving system can be used as either a single or twin cutter grooving tool for diameter ranges from Ø2.087" to Ø118". The design allows for a grooving depth up to .472", with a minimum width of .079" and a maximum of .375".

Face grooving with boring tools is generally more efficient than milling with circular interpolation, especially when manufacturing grooves of large diameters. Also, whenever a surface for a sealing application is required, there is no other acceptable or accurate option than to use a face grooving setup.

Using the boring tools as twin cutters, with a simultaneous adjustment in radius and length, allows the feed rate to be increased. Using the cutters in diameter offset operation enables a groove width of up to .472", and both inside and outside diameters can be adjusted separately within the smallest tolerances. Both cutting edges can be adjusted easily to the same length, due to an eccentric bolt mechanism with clear direction indication.
