The purchase requirements of CNC punching machine
1. Driving mode of CNC turret punch press
There are three driving modes of CNC turret punch press: hydraulic, mechanical, and servo-mechanical. The use cost of the mechanical drive method is relatively low, and the maintenance is simple, but the disadvantage is that it is noisy and mold release is a bit harsh.
The hydraulic type has a relatively high cost, but it has low noise and smooth mold release. In addition, there are requirements for the use of hydraulic equipment. The temperature cannot be lower than -5 degrees in winter and 70 degrees in summer. Therefore, cooling and heating equipment must be installed to ensure the normal operating temperature of the equipment. The all-electric servo drive is a new technology in recent years. The punching speed is higher than the above two types, but it is mostly used for punching thin plates. Therefore, it can be selected according to three driving modes.
2. The thickness of the turret
Because the thickness of the turret determines the amount of deformation of the turret, the deformation probability of a thin turret is relatively higher than that of a thick turret. Once the turret is deformed, it will directly cause mold gnawing and cannot be repaired. The turret can only be replaced. The use of a thick turret will allow the mold to have good neutrality, high guiding accuracy, and strong anti-eccentric load capacity, which greatly increases the service life of the mold. At present, thick turrets are mostly used both domestically and internationally. Of course, it depends on the material to be processed. Generally, it refers to punching workpieces of the same or several pass types on a plate with a thickness of more than 4mm and less than 15mm. It is suitable for choosing a fully automatic thick plate CNC turret punching machine.
3. The module number of the turret
According to the number of hole types, the number of stations of equipment is specifically selected. Most CNC punch presses on the market currently have 32 stations, but in many cases, 32 stations are still wasteful for most users. In fact, there are 24 stations and 20 and 18 stations. Practical, there are also 16 stations, but this is not very convenient because there is no D station, and blinds can not be made, so it is not very convenient to use. The 18 and above stations do not have this problem, and they all have at least one D station.
