Double column, also known as flat guide hydraulic cutting machine, with a pressure of generally 25 to 30 tons, belongs to the second generation of cutting machine products. It is a four column flat hydraulic cutting machine with similar driving principles, but with four column transmission Make the body run more evenly

There are three differences between a four column cutting machine and a double column cutting machine:

1. The double column cutting machine is a second-generation product from the 1970s and 1980s. The four column cutting machine is the latest light industrial processing product of the fourth generation.

2. The double column cutting machine is a single bar, single oil cylinder configuration with low balance and accuracy. The fourth generation adopts computer-controlled automated machine equipment with double oil cylinders and four column automatic balance connecting rod structure, and is designed with a double-sided fast feeding device, which is more than five times the production efficiency of the second generation cutting machine.

3. Due to price differences, the second-generation products have been largely discontinued, and only small cutting machine manufacturers produce them. The use of manufacturing materials is low, unreliable, and the price is also low. The price of the fourth generation precision four column cutting machine is twice that of the double column cutting machine.

Regarding cutting speed: The speed of a two column cutting machine is similar to that of a 30 ton four column cutting machine. If the tonnage of the four column cutting machine is slightly larger, the speed will not be as fast as that of a two column cutting machine. The speed is related to the size of the hydraulic system configuration and the size of the oil cylinder. I don't know what product you make. The general speed should be sufficient, but special requirements can be customized.

【 In depth investigation 】 Differences between hydraulic flat cutting machine and hydraulic flat cutting machine

Oil pressure and hydraulic pressure are actually the same, but the main differences are in structure and component configuration, with significant differences in height and price The current hydraulic oil is 2500 barrels per 175 liters.

Generally, new machines are replaced every six months, and then every one or one and a half years. In East and North China, the anti-wear type 46 is used, while in South China, the anti-wear type 54 is used. Due to weather conditions, the viscosity of the oil directly affects the stability of the pressure.
