Why CNC Machining Is Essential for Batch Production

The so-called mechanical processing is to process various blanks into the shapes and precision sizes we need through turning, milling, planing, grinding, boring, drilling, electric spark, shearing, bending, laser cutting and other processing methods. We can call the equipment that can complete these processing as machine tools.

Traditional mechanical processing is done by manually operating ordinary machine tools. During processing, the mechanical tool is shaken by hand to cut the metal, and the accuracy of the product is measured by the eyes with tools such as calipers.

On the basis of ordinary machine tools, adding computer numerical control technology is called CNC machine tools. CNC machining tools can automatically process products and parts directly according to the programs pre-programmed by technicians, which is what we often call CNC processing.

CNC, also known as CNC. In the official statement, the full name of CNC is “Computer numerical control”, which translates to: computer numerical control-automatic machine tools controlled by computer numerical control.

First, write a program on the computer, and then input the written program into the machine. The program is used to specify the movement sequence, trajectory, range and speed of the machine tool, and the blank is processed into semi-finished or finished parts, so as to realize automatic production of the machine tool.

We know that for parts produced in large quantities, automated or semi-automated lathes can already cope perfectly.

However, for single-piece and small-batch parts, especially when producing and processing parts with complex shapes and high processing precision requirements, automation has always been a problem.

The emergence of CNC lathes has just solved this problem. It has unique advantages in processing parts with complex shapes:

CNC machining have higher accuracy after error compensation

CNC machine tools are controlled by digital signals, and the errors in processing can be compensated by adjusting parameters, with higher processing accuracy, more stable processing quality and faster processing speed;

CNC machining tool paths are consistent and more stable

At the same time, machines replace manual operations. Since the machine tools, tooling, programs and cutting paths used are all set and fixed, the components produced are the same, and the processing quality is more stable.

It is more time-saving and labor-saving to replace processing parts on CNC machining

The production of different parts using CNC machines is generally determined by different programs. It does not need to produce and replace too many tooling and fixtures like traditional machines. When the processed parts change, generally only the CNC program needs to be changed, which saves a lot of production preparation time. It is very suitable for small batch production, new product development, etc., which helps to reduce production time and cost.

Operators can get started faster

The machine tool has a high degree of automation. After programming, you only need to start the machine and input the program to automatically and continuously produce workpieces. It has high requirements for programmers, but the technical requirements for operators are reduced. Even an ordinary employee who has just entered the industry can quickly get started and participate in production.

Common CNC machining tool types

Common CNC machine tools include CNC lathes, CNC milling machines/CNC machining centers, CNC wire cutting, CNC punching machines, CNC laser cutting machines, etc. They can complete most of the machining needs.
