Application

YAMASA MX type tools are used for the aim of the burnishing the cylindrical stepped and plain shafts. The tools provide as well as surface hardness and  at low rate calibration (measurement accuracy) beside of the burnishing. The tools provide time saving  through a high processing power and speed  and this is preference cause for the serial production

There are three types according to the process type of YAMASA MX burnishing tools.  

1) Plain Shaft Self-feeding

These burnishing tools process plain shafts. The tool provides own feeding speed which is needed while it is proccessing the workpiece. Feeding is occured free from the machine.

2) Plain Shaft Macihine-feeding

These burnishing tools process plain shafts. While the tool processes the workpiece, machine provides feeding speed which is needed

3) Stepped Shaft Machine-feeding

These burnishing tools process stepped shafts and plain shafts up to the end. While the tool processes the workpiece, machine provides  feeding speed which is needed.

The tool or the workpiece can be turned with a speed of max. 250 m/min. Machine feeding speed is possible from 0,05 mm/rev. to 0,3 mm/rev. for per roller.

 All Diamensions in mm.

Technical Features

The tools are adjusted. The adjustment capacity for every diameter is 0,5 mm. The tools have an adjustment mechanism which gives the possibbilty to adjust very high precision measurements. This mechanism provides adjustment precision up to 0,0050 mm. 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 metallic materials with 1400 N/mm2 tensile strength and hardness up to max. 42-45 HRC. Tools work by turning to right. Either tool or workpiece may turn. These tools can be used on universal or CNC lathes, machining centers, drilling machines or other machines which process by turning.  The tools can be tied to all machines easily and practically. Tools have rather a long life. It is possible to use the tools for a long time without size change due to abrasion.

Tool Structure

YAMASA MX burnishing tool consist of a body and a roller head. The tool body has a precision adjustment machanism. Cage, cone and rollers are the parts of the roller head. The roller heads fiting in to the same body can be changed. The tool shank may be morse 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).
