工作原理 Working principles 利用液压保持将高硬度**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,显着提高表面粗糙度(∠Ra0.2μm); 4.对工件表面曲线跟踪加工(曲线较低点至较高点不能**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**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**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.
