The method of the tool is through rolling burnishing finishing hole , the inner bore surface to a mirror effect. It is widely used in advanced countries .
This tool has a mechanical adjustment device ( each grid scale is 0.0025mm), bias control is very precise ( within 0.005mm 's ) to ensure consistency when mass size, each tool adjustment range is 0.5mm, fine applies to the following workpiece hardness 40HRC processing the remaining reserved rough bore , a roll , the surface roughness can be reduced from around the hole to Ra6.3 Ra0.2 ~ Ra0.5, after processing the surface hardness can be increased 40HV, increasing the wear resistance of the workpiece . Through holes and blind holes can be processed , high efficiency ( for example : processing Φ100mm × 300rnm hole can be completed within 1.5min ; Φ30mm × 40rnm hole can be completed in the 10s ) .
This tool is small, simple operation, low maintenance costs, can be used on lathes, milling, boring, drilling , machining centers and other machine tools , no special driver device, simply rotate and feed , you can simply achieve a mirror finish precision machining within a certain range , and better than fine cars can be replaced , fine boring , fine reaming, grinding, honing , grinding and other traditional techniques. It is widely used in auto parts, hydraulic, pneumatic and mechanical industries , the effect is very good. The tools and traditional grinding time are shorter by 1 /5 to 1/ 20 , also has no cutting , low power , no treatment of industrial waste, energy saving advantages , the price is only one-third of similar foreign products.
