【研磨工艺成功的秘诀】
Key to the success of finishing process.
在研磨抛光作业当中,能否达到预期的工艺效果,主要取决于研磨机、研磨石、研磨膏的正确选用和合理的研磨工艺程序四大因素。因此,选择性能良好的研磨设备,研磨石(介质)、研磨剂以及制定科学合理的研磨工艺方案极其重要。
There are four very important factors to get a good finishing result as your expected:selection of right polishing machine,right abrasive stone,right polishing agent and use the appropriate process.Selection of good quality polishing machine,abrasive stone,polishing agent and set an appropriate polishing process are very important factors.
研磨石(研磨介质)的选用
1.形状尺寸:
在进行研磨作业之前,须全面地了解工件型面的凹槽、弯角、边角、空隙的形状和尺寸来选择研磨石的形状和尺寸,同时亦须考虑分选的方便性。
2.材质:
对即将要进行研磨的工件材质、硬度、密度等特性的了解非常重要。研磨石的选用主要依据工件材质的特性进行选择。研磨石的硬度、密度与工件材质的硬度、密度的配合必须相对合适;否则,将使研磨石在研磨作业当中无法起到研磨、抛光的作用,甚至造成工件撞伤或者将研磨工件破坏。
3.加工精度:
确定研磨工件加工品质要求。不同的表面品质要求,选择不同类型、功能的研磨石及不同的工艺方案。如去毛刺、去氧化皮、倒角、抛光等。
4.比例:
合理的加工工艺方案,研磨石与研磨工件的投入比例非常重要。否则,将造成工件互相碰撞或擦伤,损坏工件表面。确定投入比例主要根据工件品质的要求、工件材质、工件形状来考虑研磨石和工件的比例。一般研磨为5:1-6:1,要求达致镜面的或工件形状尖角较多的,可为10:1甚至更高的比例。
Selection of abrasive stone(Media)
1.Shape and size:
Before starting the polishing process,it is important to get well known of the concave,edge angle,shape and size of gap of the workpiece surface.The selection of the abrasive stone depends on these factors.Convenience for sifting workpiece out also should be taken into consideration.
2.Material:
It is very important to get well known of workpiece feature,such as material,hardness and density.The selection of tha abrasive stone depends on these factors.Hardness and density of abrasive stone must watch with the hardness and density of workpiece,otherwise the abrasive stone can not grind or polish workpiece and may scratch workpiece due to the impact.
3.Requirement:
For the different purpose requirement should select different type and function abrasive stone and polishing process,such as deburring,chamfering,polishing and etc.
4.Ratio:
Select right polishing process and ratio of the abrasive stone and workpiece are very important,otherwise it may damage the workpiece due to impact and scratch.The ratio depends on requirement,material and shape of the workpiece.The general ratio is 5:1-6:1.to get a better or mirror-like surface tha ratio should be 10:1 or more.
