Inner diameter of the blind hole rolling tools

Model Number: WL-SB Key Specifications/Special Features: Specifications： 7-300mmApplication: Suitable for diameter blind holes products mirror, precision machining, such as brake pump, gear, bearing, piston brake clamp cylinder.Use method:1. Move the aluminum shell with scale up and down, and turn up and right to adjust tool diameter. Each scale is equal to 0.0025mm (see illustration 1).2. Install the tool on the main shaft of drilling, milling, and polishing machine. The tool will rotates. Conduct right rotation processing when the tool isstill. In addition, you may conduct component rotation processing when the tool is fixated. The tool shall conform to the center of the component processinghole.3. Apply cooling lubricant at processing. The lubricant shall be filter for cleanness (including rolling external diameter, plane, prick, and ball).4. The tool will automatically reduce the diameter at holding back without any damage to the processing surface.
