YAMASA MX type tools are used for the aim of the burnishing the cylindrical stepped and plain shafts.
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 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 easly 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.
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. These tools are used on universal machines.
2) Plain Shaft Machine-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 250 m/min. Machine feeding speed is possible from 0,05 mm/rev. to 0,3 mm/rev. for per roller.
YAMASA MX burnishing tools consist of a body and a roller head. The tool body has a precious adjustment mechanism. Cage, cone and rollers are the parts of the roller head. The roller heads fitting 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).
YAMASA MX Type burnishing tools can process the various diameters thanks to the adjustment specification. As an example, DX3-030,00-1-100-MK4 model burnishing tool having a nominal size of Ø30 mm is capable to process all sizes between Ø29.60 mm and Ø30.10 mm.
YAMASA MX type tools are produced in special diameters and sizes upon request. In addition, the tools with the special rolling length can also be produced.
You can use the information above to select the proper tool. If you want to take help for the tool selection, you can fill out the tool option form and send to us or to one of the related zone representation. So we can do the proper tool selection for you.
1-Tool Body Selection
At sight to the table, select the body number proper to the tool diameter.
Define the diameter which process you will apply accurately (eg.15.87 ...).
3-Process Type Selection
It is selected according to the machine and workpiece.
1: Automatic feeding (self-feeding) for plain shafts.
2: Machine feeding (not self-feeding) for plain shafts.
3: Machine feeding (not self-feeding) for stepped shafts.
4-Rolling Length Selection
Define the rolling length which is proper for the workpiece.
Rolling length is related to the shank selection.
For the tool diameter between 3-24 mm; by selection of ZS and MK shanks the rolling length is 75 mm.
For the tool diameter between 25-85 mm; by selection of ZS and MK shanks the rolling length is 100 mm.
For the tool diameter between 86-110 mm; by selection of ZS and MK shanks the rolling length is 115 mm.
For the tool diameter between 3-85 mm; by selection of ZU shank rolling length is an unlimited (U).
