YAMASA MX type roller burnishing tools for cylindrical shafts can work in H8 tolerances with a single adjustment. These tools are capable to process all kinds of materials with 1400 N/mm2 tensile strength and hardness up to max. 45 HRC. Tools work by turning with a direction of process towards right. Either tool or workpiece may turn, it doesn’t affect the result of the burnishing. These tools can be used on universal or CNC machines, machining centers, drilling machines or other turning machines. The tools are adjusted. The adjustment capacity is 0.5 mm and the tool adjustment precision is 0.0050 mm. There are two types of YAMASA MX type roller burnishing tools, for plain shafts and stepped shafts. For plain shafts, burnishing tools process the surface of shafts that have a fixed diameter. For stepped shafts, burnishing tools process stepped shafts. For plain shafts burnishing tools can be used automatically or machine feeding but for stepped shafts only machine feeding is suitable.

The tool or the workpiece can be turned with speed of 100 m/min. Machine feeding speed is possible from 0,05 mm/rev. to 0,3 mm/rev. for per roller

YAMASA MX type roller burnishing tools consist of a body and a rolling head. The tool body has a precious adjustment mechanism. Cage, cone and rollers are the parts of the rolling head. The rolling heads fitting in to the same body can be changed. The tool shank may be Mors Taper or cylindrical. Rolling lengths are related to shank selection. ZU shanks have unlimited rolling length, but ZS and MK shanks are limited. (see table below).
