Roller burnishing tool PRS-DL Single roll type

In the lathe, bychanging the shape of the head roller, the outer diameter can be processed,end, Rside, inner and outer seal groove surface, inclined, the end face of themirror roll.

Note: The tool can alsobe diamond roller ball tip replacement, material can be less than HRC65rolling, by changing the angle of tool head can be realized spherical diameter,bore mirror-polished.

Product performance and processing conditions:

1.      Reserved amount of metal rolling surface,rolling tool can make just one coining surface roughness Ra 3.2um or so downfrom between 0.4-0.04.

2.      Has a tuning device (only for bore and ODrolling knife), rolling in a reasonable margin, the size can be controlledwithin the tolerance 0.0025mm，tuningrange of up to about 0.5mm.

3.      To improve efficiency and reduce costs.Rolling process takes only 1/10-1/20 grinding, tool clamping in any rotation ofthe feed device can be used (eg: turning, milling, drilling, boring machines,CNC lathes, machining centers, etc.). Tool is simple (no training ofprofessional and technical personnel), and long-term use, simply replace therotating parts accessories, maintenance costs low.

4.      Rolled products after processing can improvethe surface hardness HV40 so, while fatigue strength increased by 30%, so thatthe product life and performance is greatly improved.

5.      Roller rolling hardness HRC40 applies onlywithin the metal processing, diamond ball rolling can be processed to HRC65.

6.      Processing required cooling and lubrication,the working fluid with low viscosity oil. Theoretically also can be processedwithout lubrication, but considering the affects tool life and surfaceroughness of the product, it is recommended to use the working fluid. (Whenused in CNC machine tools refueling of cutting fluid, when used in an ordinarymachine steel plus diesel oil, kerosene oil increases aluminum, 3:7 mix ratio,copper pieces available sewing machine oil 32# transformer oil)

7.      Before rolling the hole wall should have adeeper marks, knife pattern should be uniform, relaxation. Preferably by latheor boring machining methods such as cutting point in a regular shape of thesurface. Obtained by processing such as drilling processing surfaceirregularities, after rolling, the projecting portion is not completely fillingthe concave portion, and thus can not get a good surface finish.
