CNC cutting machine cutting quality industry standards

With the development of modern machinery processing industry, the requirements for the quality and precision of cutting have been continuously improved, and the requirements for improving production efficiency, reducing production costs, and having high-efficiency automatic cutting functions are also increasing. As a part of the cutting machine industry, the products we provide will be the most modern and technological. Welcome everyone to discuss cooperation. Details:/
CNC cutting machine cutting quality industry standard CNC cutting machine in the daily use of the operation, the grasp of cutting quality requires comprehensive consideration of various factors, for enterprises and users, how to integrate various factors, at the beginning of equipment purchase There is a preliminary understanding of the quality of the CNC plasma cutting machine manufacturers. The following Chinese cutting machine trading network will be referenced to industry-related standards. The relevant parameters of plasma cutting will be introduced briefly for everyone.
First, the width of the incision It is one of the most important eigenvalues ​​evaluating the cutting quality of the CNC cutting machine, and also reflects the radius of the smallest circle that the cutting machine can cut. It is based on the size of the incision at the widest point, most plasma cutting machine incision width between 0.15 ~ 6mm. Impacts: 1. Excessive incisions not only waste material, but also reduce cutting speed and increase energy consumption. 2. The width of the kerf is mainly related to the nozzle aperture. In general, the kerf width is always 10%~40% larger than the nozzle aperture. 3. When the cutting thickness of the cutting machine increases, it is often necessary to use a larger nozzle aperture, and the incision will also be widened. 4, increase the width of the incision, will increase the amount of deformation of the cutting piece.
Second, the surface roughness It is used to describe the appearance of the incision surface, to determine whether the need for re-processing after CNC cutting machine. It is a measure of the Ra value on the cross-section of the incision depth at 2/3. As the result of the action of the cutting air flow in the longitudinal direction of the cutting advance, the main form is the cutting corrugation. The surface roughness after cutting by the oxyacetylene method is generally required: Grade 1 Ra ≤ 30 μm, Grade 2 Ra ≤ 50 μm, Grade 1 Ra ≤ 100 μm. The value of the incision Ra for plasma arc cutting usually exceeds the flame cutting level but is lower than the laser cutting Ra value (less than 50 μm)
Third, the squareness of the cutting edge It is also an important parameter that reflects the cutting quality, and it is related to the degree of reprocessing required after the CNC cutting machine cuts. This indicator is usually expressed in verticality U or angle tolerance. In general: when plasma arc cutting, the U value is closely related to the plate thickness and process parameters, usually in U ≤ (1% ~ 4%) δ (δ is the plate thickness), laser cutting U ≤ 0.5mm
