YAMASA DX type tools are used for the aim of burnishing the cylindrical holes that have an open and closed end.
The tools are adjusted. The adjustment capacity is changing according to the diameter and types between 0,25 mm and 1 mm. The tools have an adjustment mechanism which gives the possibbilty to adjust very high precision measurements. For Ø5 - Ø80 mm tools, adjustment precision is 0,0025 mm and for bigger than Ø80 mm tools adjustment precision is 0,0050 mm. YAMASA DX type roller burnishing tools can process the cylindrical holes up to H8 tolerance 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, milling 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 of YAMASA DX burnishing tools according to the process type :
1) Through Hole Self-feeding
These burnishing tools process the holes that have an open end. The tools provide own feeding speed which is needed while it is processing the workpiece. Feeding occurrs free from the machine.
2) Through Hole Machine-feeding
These burnishing tools process the holes that have an open end. While the tools process the workpiece, the machine provides feeding speed which is needed.
3) Blind hole Machine-feeding
These burnishing tools process stepped or fully closed holes up to end. While the tools process the workpiece, the machine provides feeding speed which is needed.
The tool or the workpiece can be turned with the speed of 250 m/min. The machine feeding speed is possible from 0,05 mm/rev. to 0,3 mm/rev. for per roller.
YAMASA DX 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. The tools, which are bigger than Ø34 have an unlimited rolling length, for the tools which are smaller than Ø35 exist standard rolling lengths (see table below). For special orders, tools with longer rolling lengths can be produced.
YAMASA DX Type burnishing tools can process the various diameters thanks to the adjustability specification.
For example: DX1.2-025,00-1-50-MK2 type burnishing tool having a nominal size of Ø25 mm is capable to process all sizes between Ø24.90 mm and Ø25.90 mm.
YAMASA, DX 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 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 accurately which you will process (eg.25.40 ...).
3-Process Type Selection
Select the process type according to machine and workpiece.
1: Automatic feeding (self-feeding) for through holes.
2: Machine feeding (not self-feeding) for through holes.
3: Machine feeding (not self-feeding) for blind holes
4-Rolling Length Selection
Define the rolling length which is proper for the workpiece. It doesnt need to be stated for bigger than Ø34 mm diameter because they have unlimited rolling length but it must be stated smaller than Ø35 mm diameter. Standard rolling length is 50 mm for smaller than Ø35. For these diameters other rolling length options are 100, 150, 200, 250, 300 mm.
For the diameters of smaller than Ø35 more longer rolling length demands will be considered specifically.
