【研磨工藝成功的秘訣】

Key to the success of finishing process.

在研磨拋光作業(yè)當(dāng)中，能否達(dá)到預(yù)期的工藝效果，主要取決于研磨機(jī)、研磨石、研磨膏的正確選用和合理的研磨工藝程序四大因素。因此，選擇性能良好的研磨設(shè)備，研磨石（介質(zhì)）、研磨劑以及制定科學(xué)合理的研磨工藝方案極其重要。

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（研磨介質(zhì)）的選用

1.形狀尺寸：

在進(jìn)行研磨作業(yè)之前，須全面地了解工件型面的凹槽、彎角、邊角、空隙的形狀和尺寸來(lái)選擇研磨石的形狀和尺寸，同時(shí)亦須考慮分選的方便性。

2.材質(zhì)：

對(duì)即將要進(jìn)行研磨的工件材質(zhì)、硬度、密度等特性的了解非常重要。研磨石的選用主要依據(jù)工件材質(zhì)的特性進(jìn)行選擇。研磨石的硬度、密度與工件材質(zhì)的硬度、密度的配合必須相對(duì)合適；否則，將使研磨石在研磨作業(yè)當(dāng)中無(wú)法起到研磨、拋光的作用，甚至造成工件撞傷或者將研磨工件破壞。

3.加工精度：

確定研磨工件加工品質(zhì)要求。不同的表面品質(zhì)要求，選擇不同類型、功能的研磨石及不同的工藝方案。如去毛刺、去氧化皮、倒角、拋光等。

4.比例：

合理的加工工藝方案，研磨石與研磨工件的投入比例非常重要。否則，將造成工件互相碰撞或擦傷，損壞工件表面。確定投入比例主要根據(jù)工件品質(zhì)的要求、工件材質(zhì)、工件形狀來(lái)考慮研磨石和工件的比例。一般研磨為5：1-6：1，要求達(dá)致鏡面的或工件形狀尖角較多的，可為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.
