工作原理 Working principles
利用液壓保持將高硬度專用陶瓷球壓于金屬表面,使其塑性變形,提高了疲勞強度,并產(chǎn)生以下四種相關(guān)效果:
1.表面部分產(chǎn)生了殘余壓縮應(yīng)力;
2.加工表面硬化,增強了材料強度;
3.通過表面精壓,顯著提高表面粗糙度(∠Ra0.2μm);
4.對工件表面曲線跟蹤加工(曲線較低點至較高點不能**過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
將工件直接裝夾在車床的刀架下,點壓內(nèi)孔時,如同鏜刀鏜內(nèi)孔加工;點壓外徑
時,如同車刀車外徑。加工球面需專用車床。
加工前點壓球應(yīng)離工件1~2mm,車床旋轉(zhuǎn)后啟動油壓裝置,點壓球自動
接觸工作,就可以開始加工。
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.
注意事項 Precautions
1.加工過程中,要**油壓裝置內(nèi)的油清潔并有充分的流量;
2.加工長軸外徑時,需**住中心孔;
3.加工鋁料等軟金屬時,油壓值要調(diào)低;
4.加工盲孔時,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.避免點壓球受到撞擊。
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.
