SANAI Roller Burnish Tools Taper Shank Mirror Surface Burnish Lathe Rolling Cutter for Through Hole and Blind Hole Inner Rolling
Customized specifications of Roller Burnish Tools are acceptable. Please remark the taper fitting, MT2, MT3, or MT4 is available for you to choose. For straight shank, please visit other rolling tool link. Any questions, please feel free to leave message or contact via email: [email protected]
Description:
1. Shank type: Morse taper shank
2. Hole type: Through Hole / Blind Hole
3. Material; High Speed Steel
4. Processing hardness: HRC40 or less
5. Processing range: Through hole diameter from 3mm to 300mm; Blind hole diameter from 6mm to 300mm
6. Available taper fitting: MT2, MT3, MT4.
7. Application: Cylinder block, connecting rod, valve body, rocker arm, motor stator, etc.
Tips: for blind hole diameter 6mm or smaller, we suggest to use the through hole roller to instead.
Product Advantage
1. High quality material: HSS material, smoother, more durable, longer life;
2. 12 processes of needle rolling: more durable, more efficient;
3. Mirror finishing burnish: smoother, brighter, more efficient;
4. Self size adjusting, each to use: Maximum diameter adjusting range about 0.5MM, minimum scale 0.0025MM.
Processing Theory
Installation Method and Dimension Adjustment Instruction
1. Clamp the tools on the main axes of drilling, turning, milling, boring, CNC machine tools, machining centers and other machine tools, and the tools rotate, The workpiece is rotated right without moving; It can also be fixed by tools, the workpiece can be rotated, and the center of the tool and the machining hole can overlap.
2. Push up and down the aluminum shell with scale to rotate left and right at the same time, the diameter of the tool can be adjusted, each scale is 0.025mm.
3. Cooling lubricating oil must be used during processing, and the lubricating oil should be filtered to keep clean.
4. When the tool is returned, the diameter will be automatically reduced without damaging the processed surface.
Attention:
1.The hole wall should not have deep cut marks before rolling, and the cut lines should be uniform, loose, and the roughness should be about RAA1.6-RA3.2
2.In order to obtain reasonable rolling margin, we should choose according to the situation of the workpiece itself (mainly the material, hardness, surface roughness before rolling), so we should try 2-3 pieces before batch processing, and find out the best
3.When processing blind holes, 0.5mm at the bottom cannot be processed. In order to minimize the part that the rolling head cannot process, after adjusting the diameter of the tool, the core shaft part at the same position on the top of the needle roller is removed by grinding.
4.The workpiece must have enough wall thickness, which should generally exceed 15% of the aperture. If the wall thickness is too thin, roll it before reducing the wall thickness, or use a frame to support the periphery.
5.Select the shape of the clamping part of the tool according to the machine tool (straight handle, Morse taper handle, BT handle, etc.)
