The MEFF Chipbreaker offers versatility in various applications in swiss machining including OD turning, back turning, chamfering, tapering, profiling, and more. While the MEFF Chipbreaker is ideal for small parts machining, it can also be used in similar fine finishing applications anywhere! The new chipbreaker features great chip control in very fine finishing, where depth of cut (ap) < 0.020” and feed rate (fz) < 0.002 minches per revolution (IPR). With a unique chipbreaker design with multiple ridges, a wavy cutting edge, and high rake the MEFF Chipbreaker allows for the excellent chip control, lower cutting force and good surface finish in different depth of cuts.

MEFF Chipbreaker is available in the following Sumitomo Grades, AC5015S (1st choice for HRSA, Ti Alloy, Hardened Steel and Bearing Steel), AC5025S (tough grade for interrupted cutting of HRSA) and AC1030U (1st choice for steel and stainless steel). Test results of the MEFF Chipbreaker have indicated improved wear resistance and surface finish in materials steel, stainless steel and inconel. Finally, the MEFF Chipbreaker also delivers energy savings with significantly increased productivity by better chip control thus greatly reducing power consumption and CO2 emissions.

Sumitomo takes pride in being a leader in the development of new technologies in turning and is happy to release the new MEFF Chipbreaker for fine finishing. We are excited to help provide additional solutions to our customers!
