What Is CNC Machining ?

CNC Machining is a computer-controlled process that involves the removal of material from a workpiece.
This method is highly efficient, accurate, and fast compared to traditional machining techniques.

What Is CNC Machining Used For?

At Kachi, we offer precision CNC machining services for the production of complex finished parts, components, and tools for plastic injection molding or pressure die casting. Additionally, CNC manufacturing is utilized for secondary drilling, tapping, and milling operations on machined parts or parts made from other processes. Our team uses a variety of specialized CNC machine tools to perform various operations on raw stock, but CNC mills are the most commonly used and versatile multi-axis machines in our daily operations.

CNC Turnign Services

The general process of turning involves rotating a part while a single-point cutting tool is moved parallel to the axis of rotation. Turning can be done on the external surface of the part as well as the internal surface (the process known as boring). The starting material is generally a workpiece generated by other processes such as casting, forging, extrusion, or drawing.

CNC Milling Services

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done by varying directions on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.

Guidelines and functions for CNC milling

    • CNC milling is a subtractive manufacturing process where parts are rapidly milled from raw material blocks using G-code programmed CNC milling machines. 3-axis and 5-axis CNC machines come equipped with various toolsets to enhance efficiency and production speed. Plastic parts maintain their milled state after machining, while metal parts can undergo surface treatments such as anodizing and chrome plating. After the machining is complete, the parts undergo surface finishing treatment before being packed and shipped.

Surface finishing involves the process of altering a metal’s surface through reshaping, removing or adding, and is used to measure the overall texture of a surface characterized by:

Lay – The direction of the predominant surface pattern (often determined by the manufacturing process). Waviness – Pertains to fine detail imperfections or coarser irregularities, such as surfaces that are warped or deflected from specifications.

Advantages of Metal Surface Finishing Process

The functions of metal surface treatment can be summarized as follows:
-Improve parts appearance
-Add specific beautiful colors
-Change the luster
-Enhance chemical resistance
-Increase wear resistance
-Limit the effects of corrosion
-Reduce friction
-Remove surface defects
-Cleaning the parts
-Serves as a primer coat
-Adjust the sizes
