赛万特内孔滚压刀 镜面滚压工具 通孔型滚压刀 内圆挤光刀
滚压加工是一种无切屑加工，通过一定形式的滚压工具向工件表面施加一定压力。在常温下利用金属的塑性变形，使工件表面的微观不平度辗平从而达到改变表层结构、机械特性、形状和尺寸的目的。因此这种方法可同时达到光整加工及强化两种目的。

使用方法 Use
1.将工具装夹在钻、车、铣、镗床和数控车床、加工中心等机床主轴上，工具转动，工件不动进行右旋转加工，也可工具固定，工件旋转加工，工具与加工孔的中心重合。
加工条件:
| 工件直径mm Component diameter | 4~14.5 | 15~24 | 25~44 | 45~74 | 75~99 | 100~139 | 140~200 |
| 转速r/min Rotation speed | 1500~1000 | 1000~800 | 800~500 | 700~400 | 500~300 | 400~250 | 300~150 |
| 进给速度mm/rev Feed speed | 0.1~0.4 | 0.2~0.6 | 0.3~1.0 | 0.4~1.2 | 0.5~1.5 | 1.0~2.0 | 1.2~2.5 |
2.上下推动有刻度铝壳同时左右旋转，可调整工具直径，每格刻度为0.0025mm(见图）。调整范围0.5mm
3.加工时必须用冷却润滑油，润滑油要过滤并保持清洁（也包括滚压外径、平面、 锥面、球面）。
4.工具退回时会自动缩小直径，不会损伤已加工表面。
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 is
still. In addition, you may conduct component rotation processing when the tool is fixated. The tool shall conform to the center of the component processing
hole.
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.
注意事项 Precautions
1.滚压前孔壁不宜有较深刀痕，刀纹应均匀、松弛（此条件也包括滚压外径、平面、锥面、球面），粗糙度Ra3.2左右。
2.为了获得合理的滚压余量，应根据工件本身情况（主要是材质、硬度、滚压前表面精糙度）有所选择，故批量加工前应试加工2~3件，求出最佳滚压余量。（见表）
| 工件直径mm Component diameter | 4~11.9 | 12~30 | 31~59 | 60~89 | 90~149 | 150~179 | 180~200 |
| 预留加工余量mm Preserved processing remnant | 0.005~0.02 | 0.01~0.025 | 0.015~0.03 | 0.025~0.04 | 0.04~0.08 | 0.05~0.1 | 0.06~0.12 |
3.加工盲孔时底部约0.5mm无法加工，为使滚压头不能加工的部分最小，调整好工具直径后，磨削除去滚针顶端部同样位置的心轴部分。
4.工件必须有足够的壁厚，一般应超过孔径的15%，若壁太薄，应在减少壁厚前进行滚压，或用一个型架来支撑周边。
5.根据机床选择好工具装夹部形状(直柄、莫氏锥柄、BT柄等)。
1. For proper refined remnant, select properly in accordance with the component situation (mainly the materials, hardness, and coarseness of the surface before rolling). Therefore,
before batch processing, trial process 2 to 3 components, such that best tool diameter may be obtained. (See the table)
2. Select clean cooling lubricant with low viscosity. Regularly clean the rolling heads. (Clean with oil and diesel oil for steel components. Clean with mixture of oil
and diesel with ratio of 3:7 for aluminum components. In addition, you may also clean with sewing machine oil for aluminum components. Clean with 32# converter cooling
fluid for copper components, at best with specialized Jingheng rolling lubricant.)
3. At processing blind hole, there would be about 0.5mm length at the bottom beyond processing. In order to minimize the length beyond processing, eliminate the spindle of the
rolling pin head through milling after adjusting the tool diameter.
4. The component shall bear adequate wall thickness, generally more than 15% of the hole diameter. Conduct precise pressing before reducing the wall thickness, or supported by a
frame if the wall is to thin.
5. Avoid deep cutting trace before rolling. The trace shall be uniform and loose (including rolling external diameter, plane, prick, and ball).
