Best Power Press in 2022 And Cheap Punching Machine For Sale

The differences between CNC punch presses and ordinary mechanical punch presses are as follows:

1. Speed

The speed of ordinary mechanical punching machine is slow, ordinary punching machine is only under 200 strokes/minute, while CNC punching machine is generally about 3-800 strokes/minute.

2. Accuracy

The precision of ordinary mechanical punching machine is average, while the precision of CNC punching machine is high, and the precision can reach 0.01mm.

3. Price

Ordinary mechanical punches are generally very cheap, a common tonnage ordinary punch is between a few thousand dollars and 20,000 dollars, while a CNC punch is generally between 10,000 and 80,000 dollars. The budget for a CNC punch can buy 2-3 ordinary mechanical punches with the same impact, and some even more.

4. Controllability

Ordinary mechanical punching machines can only do simple up and down punching movements, which can be controlled by hand or foot; while CNC punching machines can be controlled by the display screen or manually.

5. Security

Ordinary mechanical punching machines have no safety devices and are prone to danger; CNC punching machines have photoelectric protection devices and servo motors. As long as the hand enters the protection zone, the machine will automatically stop working.

6. Cost-performance ratio

Ordinary mechanical punching machines are suitable for processing some products with low added value. Generally, they cannot be automated. They can only be manually operated and the speed is slow. However, CNC punching machines can be automated and can be mass-produced, saving a lot of labor costs a year. In the long run, they are still servo punching machines. Cost-effective.

The use of the punching machine is very wide, the power press is to punch the sheets. Through the mold, it can make blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts, etc., which are widely used in various fields.

Punch automatic feeding device refers to the equipment that cooperates with the punch to achieve automatic feeding, such as NC servo feeder, 3-in-1 feeder, left and right yaw feeder, roller feeder, leveler, material rack, etc.
The automatic punch feeder is easy to operate and has high precision. As long as the feed is set on the touch screen during operation, the servo system automatically determines the feed length for each time according to the preset value. The operator only needs to watch whether the machine is working normally, and does not need to adjust each time.
The PLC system controls the automatic feeding action, automatic clamping action and automatic cutting action. The use of this machine can greatly reduce the labor intensity of the operator and improve production efficiency.
