Mxm type roller burnishing machine Yamasa mxm roller burnishing machines can process the cylindrical shafts up to h8 tolerances with a single adjustment. These machines are capable to process all kinds of metallic materials with 1400 n/mm¦ tensile strength and hardness up to max. 42-45 hrc. Super finish surfaces up to ra= 0, 02 ¦m can be obtained. Mxm type burnishing machines realize the part feeding and tolerance adjustment automatically. The workpiece is taken then removed after the burnishing process is completed. The machine has full automatic specifications. It is capable to achieve a rapid production thanks to the automatic feeding system. It can be integrated to each production line for every kind of serial production. As well as automatic loading system can be integrated.
