About Milling Process


Milling can be done with a wide range of machine tools. The original class of machine tools for milling was the milling machine. Our CNC milling process is capable of 3-axis (x,y and z), 4-axis and 5-axis (x,y,z, A and B) milling for high speed cutting of engineering-grade materials into product prototypes and precision end-use parts. The specific process is as follows:

① Create the original CAD model
② The original CAD model is transformed into a complete program
③ Set up the milling machine according to the CNC program
④ Parts processing production


Why Choose Us


First Part is a leading rapid prototyping, rapid tooling & low-volume manufacturing in the world. CNC precision machining can be applied for:


Face Milling Machines


Face milling is the most common milling process, that is, the rotation axis of the cutter is horizontal milling machine, flat milling is perpendicular to the workpiece, along the direction of motion parallel to the surface of the workpiece! This can be performed using a variety of different tools.The most commonly used is 45° main Angle milling cutter, but in some cases circular blade milling cutter, square shoulder milling cutter, and three side edge milling cutter may be used.

The advantage of CNC milling


ACNC milling greatly improves the processing efficiency, and can obtain a high surface finish.In addition, it can also process high hardness modules, and has the advantages of low temperature rise and small thermal deformation. The development of milling technology has injected new vitality into the manufacture of large cavity die in automobile and home appliance industry.It has been developing towards higher agility, intelligence and integration.

What is CNC Milling?


CNC milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. CNC milling tools perform a machining process much like both drilling and cutting. CNC milling is ideal in making angles shapes, slots, holes and curves, flat surfaces and channels. It is efficient in removing surfaces with high accuracy.

Different type of milling


Design and process different types of parts and functions, will use different types of milling machine, the following are several common types of milling machine:

Multi-Axis Machines


We are familiar with CNC machine tools have three linear axes XYZ, multi-axis refers to a machine tool with at least the fourth axis.Usually referred to as multi-axis CNC machining refers to more than 4 axis CNC machining, which is representative of the 5-axis CNC machining. The continuous 5-axis CNC milling machines are similar to the indexed setups. They allow the movement of all axis (X,Y,Z, A and B) concurrently during machining. It allows for continuous movement that enhances the accuracy and the cut and allows for parts with complex geometries to be manufactured.

Vertical Milling Machines


In a vertical milling machine, the main axis is vertically oriented.The cutter is fixed in the main shaft and rotates about its axis.Often, the same effect can be achieved by extending the spindle or raising or lowering the table for undercutting and milling.There are two types of vertical milling machines, namely the bed milling machine and the cutter tower milling machine.
