The Difference Between a Normal Punch Press and A High-Speed Punch Press

In the machinery manufacturing industry, punching machines are essential tooling processing machines and equipment.

There are also many types and specifications of precision punching machines. What is the difference between a high-speed punch press and a normal punch press?

Is it just the difference in speed? Is the high-speed press better than the general one?

High-speed presses are better than ordinary ones in terms of precision, tensile strength, speed, system software stability and actual operation of the structure, but it does not mean that high-speed presses are better than ordinary ones.

The specific purchase must also be based on the actual decision to be sure.

1, rate: ordinary type generally in the following 110 ~ 200 times, while the high-speed in 200 ~ 1100 times up and down.

2, shell raw materials: high-speed punching machine shell raw materials with high rigidity and use performance, more stable precision, while the ordinary type is not.

3, Operating method: general ones have manual type, foot pedal and CNC machine tools, etc., while high-speed ones are CNC machine tools and fully automatic ones.

4, precision: general have general and high precision, and high-speed are high precision, even to 0.01mm.

5, use: general punching machine is important for electronic components and other manufacturing industry parts of the molding, drop and other cold punching die processing process; high-speed punching machine is commonly used in the manufacture of high precision parts.

6, grinding tool: general punching machine grinding tool is the key to single stamping die, maintenance costs increase; high-speed punching machine grinding tool can be both single stamping die can also be even into the die.

7, Price: High speed is higher than the general price.

8, Eccentric shaft: The design scheme of the eccentric shaft of the high-speed punching machine is much stronger than normal, which can bear a lot and is not easily deformed.

9, the system software stability: high-speed punching machine important system software using pressure display, a little higher stability.

Then how to choose high-speed punching machine?

High-speed punching machine precision selection: as the saying goes, "no diamond, don‘t take the porcelain work", "work to be good at its work, must first benefit from its tools".

The market demand is becoming more and more fierce, and a company should not only save cost but also improve the quality of products in order to sustain the development trend and enhance its competitive ability.

Punching machine accuracy key.

1. Parallelism

2. Perpendicularity

3. The total gap

To ensure that the fixed points under the dynamics are within the difference, to promote the production of each commodity are up to standard, and the spare parts in the mold will not be destroyed.

The accuracy of the punching machine is comparable to the accuracy of Japanese punching machine, and it is within the JIS standard. The special processing technology makes the crankshaft maintain the true roundness, so the parallelism of the upper and lower fixed points is extremely accurate.

The high precision punching machine not only can produce good products, but also has less damage to the mold, which not only saves the time of mold maintenance but also saves the maintenance cost.

High-speed punching machine speed selection: There are two kinds of speed in the market called high-speed punching machine.

One is Z high speed 400 times/minute and the other is 1000 times/minute.

If your product tooling requires a speed of 300 times/minute or higher, you should choose a press with 1000 times/minute.

Since the equipment cannot be applied to the limit, and the presses within 400 cycles/minute usually do not have a forced lubrication system, only grease is used to lubricate the bone part.

The punching needle structure adopts the slider type, the accuracy cannot be guaranteed, in the long-term work damage quickly, the accuracy is reduced, the mold is easily destroyed, the equipment and mold overhaul rate are high, and the delay endangers the delivery date.

The appearance of high-speed punching machine structure: quality structure can guarantee the accuracy of the equipment.

The press foot base is the basic of the machine, and the shell is the guarantee of the accuracy of the machine.

The crankshaft and the key steel connected to it are all made of imported steel from Japan.

The bearings are made of SKF bearings from Sweden. In order to have higher precision in the punching work (dynamic), the press adopts a spring balance system behind the ram.

The punching machine adopts frequency-controlled motor, which has low functional loss and saves up to 30% of power for the same tonnage in high-speed punching machine.
