How to choose right CNC plasma cutting machine for your metal work

China's CNC cutting industry developed relatively late, there are more than a dozen domestic manufacturers of CNC plasma cutting machine, the annual market demand is about 350-400, basically meet the domestic market demand, imports less than 10% of the total market.

The product development of cutting industry in our country has broken the traditional boundary between welding and cutting. Its products have crossed the two major industries of welding and cutting. Many enterprises produce welding and cutting equipment at the same time. There are also disorderly market competition in the cutting machine industry, which is manifested in mutual depreciation, price reduction and digging; little or no investment in R&D; little difference in mechanical and control level with foreign products, but not thorough understanding of foreign control systems, only staying at the level of application; no cooperation between enterprises. Can not unite to open up the market, such as in the procurement of supporting parts of the enterprise together will reduce costs and other issues.

1. Cutting accuracy of CNC plasma cutting machine: For construction industry, the general requirement is less than <0.5mm; but for automotive mirrors, the requirement is less than <0.01mm. At present, the cutting accuracy provided by various machinery manufacturers is generally below (+0.2 mm), but this can not just read the introduction of product specifications, in acceptance should have a complete set of test cutting accuracy procedures, to measure the actual cutting accuracy of the product, we generally have more than a dozen test samples. Through the test, we can master the flatness of the cutting platform and the synchronous control level of the control system.

2. Cutting speed of CNC plasma cutting machine: we can talk about speed on the premise of satisfying the cutting precision. Because the cutting platform is short, it is difficult to judge whether the highest speed is reached with the eyes. We can use the software simulation function of the servo driver of the cutting machine to check whether the motor has reached the highest speed. When testing the cutting speed, it does not need to be cut to improve the speed of addition and subtraction. Each shaft can be tested separately, and can be tested at the same time.

3. Automatic typesetting optimization function of NC plasma cutting machine: on the edge of the cutting machine, considering the processing cost and the particularity of the type of work, generally will not arrange people with high education to do, which requires the operation of the cutting machine to be simple, easy to understand, not too complex, otherwise it will cause an embarrassing situation that the machine can not afford to support. Noodles. It is better to have the function of avoiding defects, because sometimes there are bad products in the domestic floor glass. The graphics library of special-shaped cutting should be flexible and flexible, so that the graphics made by CAD can also be involved in typesetting.

4. Maintenance of CNC plasma cutting machine is convenient: I/O signal and mechanical sensors should not be equipped with too much, unnecessary switches and indicators should be as few as possible, because once a mechanical device failure will affect the use of the cutting machine, components with fewer failure probability, wiring is also less, easy to find fault and replace components, the most Fortunately, the state of each I/O signal can be debugged on the screen. Maintenance cost is an important factor that must be considered when buying a machine. 5. Saving energy: In the same cutting size requirements can be completed, the choice of energy-saving CNC plasma cutting opportunities to bring many benefits to the enterprise. One is to protect the environment and save energy; the two is to save the daily expenses of enterprises.
