工作原理 Working principles

利用液压保持将高硬度专用陶瓷球压于金属表面，使其塑性变形，提高了疲劳强度，并产生以下四种相关效果：

1.表面部分产生了残余压缩应力；

2.加工表面硬化，增强了材料强度；

3.通过表面精压，显著提高表面粗糙度（∠Ra0.2μm）；

4.对工件表面曲线跟踪加工（曲线最低点至最高点不能超过2mm）。

Using hydraulic keep will high hardness special ceramic ball pressure on the metal surface, make its
plastic deformation, improve the fatigue strength, and produce the following four related effect:
1. The surface of the residual stress produced compression; 2. The machined surface hardening,
enhance the strength of material; 3. Through the surface of pure pressure, improve the surface
roughness (< Ra0.2 μ m) 4. On the surface curve tracking processing (curve to the lowest point high no more than 2 mm).

使用方法 Use

将工件直接装夹在车床的刀架下，点压内孔时，如同镗刀镗内孔加工；点压外径
时，如同车刀车外径。加工球面需专用车床。
加工前点压球应离工件1~2mm，车床旋转后启动油压装置，点压球自动
接触工作，就可以开始加工。

The workpiece clamped directly under the lathe tool, some pressure in the hole, like
boring boring hole processing knife; pointPressure outer diameter, like lathe tool car
outside diameter. Processing sphere need special lathe.
Processing should be the ball from front pressure 1 ~ 2 mm, lathe, after turn start
hydraulic device, point pressure ball to be automatic Contact with work, you can start
to processing.

注意事项 Precautions
1.加工过程中，要保证油压装置内的油清洁并有充分的流量；
2.加工长轴外径时，需顶住中心孔；

3.加工铝料等软金属时，油压值要调低；
4.加工盲孔时，有3.2mm不能到底部；

5.加工前工件表面粗糙度值Ra3.2左右;
6.避免点压球受到撞击。

1. The machining process, to ensure the hydraulic device inside the oil clean and have full flow;
2. The long axis diameter processing, need to resist center hole;
3. Machined aluminum materials, and other soft metal, hydraulic value to lower;
4. Processing blind holes, have 3.2 mm can't exactly department;
5. Before processing surface roughness of workpiece value about Ra3.2;
6. Avoid point pressure ball hit.
