Post Processing
Introduction
As a precision CNC machining services supplier, a wide variety of machines are used for workpieces post processing to meet functional or decorative requirements generally listed as below:
1.) Grinding
A grinding machine is used to complete or modify a component that must be featured with high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension.
The size, shape, features and desired production rate of workpieces determine which of the following grinding operations are used at Apporo:
- Surface Grinding
- Outside Diameter Grinding
- Centerless Grinding
- Through Feed Grinding
2.) Coating (Plating)
The end workpieces should meet functional requirements such as durability or scratch resistance, and aesthetic appearance. The application of coating can be decorative, functional or both to meet your requirements.
The color, features and desired functions of workpieces determine which of the following coating operations are used at Apporo:
- Liquid Coating
- Powder Coating
- Electro Deposited Coating
3.) Plating
Electroplating is to deposit a metal on a conductive surface of CNC workpiece. Some of the benefits of plating include: increased resistance to corrosion, improved hardness, superior strength, resistance to wear, improved IR reflectivity, improved ductility, improved solderability, improved paint adhesion, altered conductivity and for other purposes.
Different plating chemicals incorporated into the process deliver anything from a semi-bright and fully bright cosmetic effect, matte or satin finishes.
- Nickel Plating
- Chrome Plating
- Zinc Plating
- Black Oxide
- Anodizing
4.) Other post processing
- Chamfer and Bevel
A chamfer is a beveled edge of a hole, frequently cut at a 45° incline to the 'normal' surface to break a sharp edge. In comparison, a chamfer is made at a 45° angle to the adjacent principal faces, whereas a bevel is a sloping edge between two principal faces.
- Sandblasting
Abrasive is fed into a stream of high-pressure compressed air and is accelerated as it flows out of the blasting nozzle against a metal workpiece surface to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants. It is widely used in different industries, such as: automotive industry, metal-manufacturing industry, foundry, aviation industry, shipbuilding, production of various welded structures, etc.
- Tapping
Thread tapping is available in our machining processes, including CNC milling or CNC turning parts, metal or plastic hardware, electronic industry, automobile and motorcycle industry, sanitary equipment, electrical and air power tools, plate for outer case, computer parts, secondary machining process in press machine, etc.
