| Introduction

As a precision CNC machining service provider, we utilize a diverse range of machines for post-processing workpieces to meet functional and aesthetic requirements. Some common post-processing methods include:

1, Grinding

In Overland, the selection of grinding operations depends on the size, shape, features, and desired production rate of the workpieces. We offer the following grinding operations:

  • Surface Grinding: Used to achieve high surface quality and dimensional accuracy on flat surfaces.

  • Outside Diameter Grinding: Ideal for achieving precise dimensions and surface finish on the outer diameter of cylindrical workpieces.

  • Centerless Grinding: Suitable for grinding cylindrical workpieces without the need for centers, providing excellent roundness, dimensional accuracy, and surface finish.

  • Through Feed Grinding: Utilized for high-volume production, where workpieces are continuously fed through the grinding machine to achieve consistent dimensions and surface finish.

2, Coating (Plating)

In Overland, the selection of coating operations depends on the color, features, and desired functions of the workpieces, considering both functional requirements such as durability and scratch resistance, as well as aesthetic appearance. We offer the following coating operations:

  • Liquid Coating: This method involves applying a liquid coating material, such as paint or varnish, onto the surface of the workpieces. It provides versatility in terms of color options and can offer both decorative and functional benefits.

  • Powder Coating: In this process, a dry powder coating material is electrostatically applied to the workpiece’s surface. The coating is then cured to form a durable and decorative finish. Powder coating provides excellent resistance to wear, corrosion, and chemicals.

  • Electro Deposited Coating: Also known as electroplating, this process involves depositing a layer of metal coating onto the workpiece’s surface through an electrochemical reaction. It offers enhanced durability, corrosion resistance, and can provide decorative finishes.

3, Plating

Electroplating is a process used to deposit a metal onto a conductive surface of a CNC workpiece. It offers various benefits including increased resistance to corrosion, improved hardness, superior strength, resistance to wear, improved ductility, enhanced solderability, better paint adhesion, altered conductivity, and more. Different plating chemicals can produce different cosmetic effects such as semi-bright, fully bright, matte, or satin finishes.

Common types of plating include Nickel Plating, Chrome Plating, Zinc Plating, Black Oxide, and Anodizing.

  • Chamfer and Bevel

A chamfer is a beveled edge, often cut at a 45° angle to the surface to remove sharp edges. It differs from a bevel, which is a sloping edge between two principal faces.

  • Sandblasting

Abrasive blasting involves propelling abrasive particles with high-pressure compressed air to smooth, roughen, shape, or clean metal surfaces. It’s commonly used across industries like automotive, metal manufacturing, foundry, aviation, shipbuilding, and welding.

  • Tapping

Thread tapping is offered in our machining services for various industries, including CNC milling and turning, electronics, automotive, sanitary equipment, tools, computer parts, and more.
