Overview

In the machining process, the plate cutting commonly used methods are manual cutting, semi-automatic cutting machine cutting and cutting machine cutting. Manual cutting flexible and convenient, but the poor quality of hand cutting, size error, material waste, follow-up processing workload, while poor working conditions, low production efficiency. Semi-automatic cutting machine in the profile cutting machine, cutting the workpiece quality is better, because of its use of cutting mold, not suitable for single, small batch and large workpiece cutting. Other types of semi-automatic cutting machine, although reducing the labor intensity of workers, but its function is simple, only suitable for some of the more regular shape of the parts cut. CNC cutting relative to the manual and semi-automatic cutting method, can effectively improve the efficiency of cutting plate, cutting quality, reduce the operator's labor intensity. Some small and medium enterprises in China even in some large enterprises in the use of manual cutting and semi-automatic cutting is also more common.

China's machinery industry, steel use has reached more than 300 million tons, the amount of steel cutting is very large; with the development of modern machinery industry, the sheet metal cutting work efficiency and product quality requirements also increased. So the market potential of CNC cutting machine is still very large, the market outlook is more optimistic.

Stepper drive, analog servo drive to today's all-digital servo drive;

The main varieties of CNC cutting machine include the following:

CNC flame cutting machine

CNC plasma cutting machine

CNC laser cutting machine

CNC high pressure water jet cutting machine

Other special special cutting equipment (such as CNC pipe cutting machine, CNC profile cutting machine, other non-metal special cutting equipment, etc.)

2, the characteristics of various types of CNC cutting machine and its application

CNC cutting machine, cutting with a large thickness of carbon steel cutting capacity, cutting costs are low, but there are cutting deformation, cutting accuracy is not high, and cutting speed is low, cutting warm-up time, perforation time is long, more difficult to adapt to fully automated The need for operation. Its application is mainly limited to carbon steel, large thickness of the plate cutting, in the thin carbon steel sheet cutting will gradually be replaced by plasma cutting.

CNC plasma cutting machine, plasma cutting with a wide cutting area, can cut all the metal sheet, cutting speed, high efficiency, cutting speed of up to 10m / min or more. Plasma cutting underwater can eliminate the noise, dust, harmful gases and arc pollution during cutting, effectively improving the environment of the workplace. With the fine plasma cutting has made the cutting quality close to the laser cutting level, with the high-power plasma cutting technology is mature, cutting thickness has exceeded 100mm, widening the CNC plasma cutting machine cutting range.

CNC laser cutting machine, with cutting speed, high precision, laser cutting machine is expensive, high cutting costs, only suitable for sheet cutting, high precision requirements of the occasion,

CNC high pressure water jet cutting machine, suitable for any material cutting (metal, non-metallic, composite), cutting high precision, does not produce thermal deformation, with environmentally friendly cutting methods. Its shortcomings lies in the cutting speed is slow, low efficiency, high cutting costs.
