Polishing technology is widely used in precision machining field, It’s very important processing that no matter for precision machined parts or Mold Parts. With the wide application of hardware products, the appearance quality requirements for hardware is becoming more and more higher, then the requirements for surface polishing will also be higher, and the roughness requirements for mirrored and highlighted surface products is especially higher, so the requirements for polishing also becoming higher and higher. Polising Not only increases the beauty of the precision machined parts, but also can improve the Corrosion and wear resistance of the material surface for precision machining parts, it also Convenient to Injection molding processing such as making plastic products easy to demold, reduce the production of injection cycle etc.
A:Rough polishing and grinding: The surface was normally rough after processing of Lathe, Grinding, CNC, cutting or EDM, It need be polished by using oilstone, Use kerosene as the lubricant,the General order of use will be #180 ~ #240 ~ #320 ~ #400 ~ #600 ~ #800~ #1000.
Whetstone polishing is very important and difficult processing, According to the different specifications of processed products like automotive parts, Cross lapping was performed equably at an Angle of about 70 degrees, The optimal round trip range is about 40 ~ 70 mm. Whetstore processing will also be changed according to the material for machined parts, In order to save the time, they will choose #400 to start.
B: Normal Polishing mainly use sandpaper and kerosene.After Whetstone processing will be sanding paper, When sanding paper, pay attention to the round edges, sharp corners, round corners and orange peel appears. so the process of whestone should be done with high precision. The important point for Sanding paper: Sand paper is intersected with hard sticks for grinding like Whetstone processing , and the grinding frequency of one side of sand paper is about 10 ~ 15 times. If the grinding time is too long, the abrasive force of sand paper will be reduced, and then it will lead the surface finish be uneven( This is one of the reason for orange peel appears). sanding paper usually use bamboo piece to grind, Actually the optimal ways is use the wood bar with less elastic or aluminum bar with Low hardness to grind at a 45 degree angle. The grinding surface should not be rubber or highly elastic materials, it can be grind at Acute Angle if the shape can’t grind at 45 degree angle. The Numbers of sandpaper are #220~ #320~ #400 ~#600~ #800 ~#1000~#1200~#1500. In fact #1500 sandpaper is only suitable for hardened die steel (above 52HRC) and not for prehardened steel as this may cause surface burns to the prehardened steel.
C:Precision polishing mainly use diamond paste. If use polishing wheel that mixes diamond abrasive powder or paste to grinding, The paste and polishing wheel can remove the Grinding crack that remained by #1200 and # 1500 sand paper. and then polishing by using felt and diamond paste.It can use the clean polishing chamber in mold processing workshop directly if the polishing precision is Ra0.2, If the polishing precision is very high, then it must use an absolutely clean space to process. It will scrap the polishing surface in high precision if the space has Dust, smoke, dandruff and spittle.
Our Kanou Precision use these polishing technology to service the customer, and also provide kind of solution for customer’s project. We always provide the precision machining part, cnc machined part, CNC turned part, CNC millded part, Mechanical components, automotive spare part to customer, Especially for mass production auto part, these all need this polishing technology, and we received highly praise from customer. We will keep to learn more polishing skills, and bring more advanced polishing tool and meterial to provide more high precision spare parts to customer.

Most people who are new to industry have a difficult time knowing the difference between CNC Milling and CNC Turning. these two processes seem quite similar. But they differ from how they operate to complete the desired part.
CNC Turning Machines are one of the oldest and simplest forms of machining parts, called “lathes,” and can be either horizontal or vertical depending on the weight and tolerance of the workpiece. The primary function of a CNC Turning Center is that it turns your workpiece. Workpieces for this process are usually round, but can be other shapes — like squares or hexagons.
The workpiece is held in place by an instrument known as the “chuck.” The chuck then spins at various RPMs (depending on the capability of your machine). When this occurs, the machine’s tool moves into the rotating workpiece and begins to shave away material to create the desired shape.
In this picture, we have a CNC Milling Machine with all the above-mentioned components as well. The top part is the Spindle, which holds the Tool. This part spins at high RPMs and moves back and forth, left and right, up and down to mill away the material.The workpiece, which in this case seems to be a gear or clutch, is held in place by the bed. Some CNC Milling Machines have the capability to move the bed in conjunction with the spindle to attain specific shapes at certain degrees. Because of these capabilities, CNC Milling offers cutting solutions for more complex parts, like engine components, custom tooling, intricate mechanisms and enclosures.
Simple In Summary,
1.Cnc turning Machine can handle only cylindrical ,or circular workpiece.While cnc lathe is used for all types of workpiece but relatively less in size.
2.CNC turning machine is turn the workpiece, the CNC milling machine is turn the tool.
