What are the characteristics of CNC machine tools compared with ordinary machine tools?

Difference between CNC Lathe and Ordinary Lathe

1, using fully enclosed or semi-enclosed protective device CNC lathe adopts enclosed protective device to prevent chips or cutting fluid from flying out and bringing unexpected harm to the operator.

2. CNC lathes with automatic chip removal device mostly adopt inclined bed structure layout, which is convenient for chip removal and automatic chip removal machine.

3, the spindle speed is high and the workpiece clamping is safe and reliable. Most CNC lathes use hydraulic chuck, which makes the adjustment of clamping force convenient and reliable, and also reduces the labor intensity of operators.

4. Automatic tool change CNC lathe adopts automatic rotary tool rest, which can automatically change tools during machining and continuously complete multi-process machining.

5. The main drive and feed drive are separated. The main drive and feed drive of CNC lathe adopt their own independent servo motors, which makes the transmission chain simple and reliable. At the same time, each motor can move independently to realize multi-axis linkage.

Compared with ordinary machine tools, CNC machine tools have the following characteristics:

(1) Advantages

1. High processing precision and high processing quality;

2. Multi-coordinate linkage can be carried out to process parts with complex shapes;

3. When the processed parts change, it is generally only necessary to change the numerical control program, which can save the production preparation time;

4. The machine tool itself has high precision and rigidity, and can choose favorable processing dosage and high productivity (generally 3~5 times that of ordinary machine tools);

5. The machine tool is highly automated, which can reduce the labor intensity;

6. Mass production and easy control of product quality;

(2) Disadvantages

1. Low quality requirements for operators and high technical requirements for maintenance personnel.

2. But its processing route is not easy to control, unlike ordinary machine tools.

3. inconvenient maintenance and high technical requirements;

This process is not easy to control.
