The double column is also called the plane guide hydraulic cutting machine. The pressure is generally 25 tons to 30 tons. It belongs to the second generation cutting machine product. The four-column plane hydraulic cutting machine has similar driving principle, but the four-column transmission makes the machine run more balanced.
There are three differences between the four-column cutting machine and the two-column cutting machine:
1. The double-column cutting machine is the second generation 70-80s product. The four-column cutting machine is the fourth generation of the latest light industrial processing products.
2, double-column cutting machine is a horizontal bar, single cylinder configuration, balance rate and accuracy is lower, the fourth generation uses computer-controlled automatic machine equipment double cylinder, four-column automatic balance link structure, and designed with bilateral fast feeding device, is The second generation of cutting machines is five times more efficient.
3, the price difference, the second generation of products basically stopped production, only small cutting machine manufacturers have production, the use of manufacturing materials is low, unreliable, and low prices. The price of the fourth-generation precision four-column cutting machine is twice that of the double-column cutting machine.
Regarding the cutting speed: the speed of the two-column cutting machine and the 30-ton four-column cutting machine are similar. If the tonnage of the four-column cutting machine is slightly larger, the speed will not catch up with the two-column. The speed is related to the size of the hydraulic system and the size of the cylinder. I don't know what product you are doing. The general speed should be sufficient, and the special requirements can be customized.
[In-depth investigation] the difference between hydraulic flat cutting machine and hydraulic flat cutting machine
The oil pressure and hydraulic pressure are actually the same. The difference is mainly in the structure and the configuration of the parts. The difference between the height and the height is also quite large. The price difference is still quite large. The current hydraulic oil is 2,500 barrels and 175 liters.
Generally, the new machine is replaced in half a year, then it is changed once in 1 year or 1 year and a half. In the East China and North China, the No. 46 anti-wear type is used. In South China, the No. 54 is used. Because of the weather, the oil consistency directly affects the pressure. Stability.
