③． NC数控下料，NC下料时首先要编写数控加工程式，利用编程软件，将绘制的展开图编写成NC数拉加工机床可识别的程式，让其根据这些程式一步一刀在平板上冲裁各构形状平板件，但其结构 受刀具结构所至，成本低，精度于0.15。
Factors that affect the quality of the cabinet of the sheet metal processing machine case?
When sheet metal processing cabinet, we all know that the requirements of the current client are very high, and the requirements of the appearance are very strict. In fact, this appearance is not only related to the beauty of the problem, but also directly reflects the quality of the product, but also has a great effect on the use of the future. The appearance of the cabinet is self-evident, in order to avoid the appearance of the impact of the quality of the product, in production and production, must be careful, when there are problems in appearance, must be timely remedies, or even elimination.
Methods / steps
Blanking: there are various ways of blanking, mainly in the following ways.
Scissors: it is a simple material for cutting the strip by cutting the cutting bed. It is mainly prepared for the molding of die blanking. The cost is low and the precision is less than 0.2.
(2). Punching machine: it is a kind of shape material that can be blanked out by one or more steps on the plate. The advantage is that it takes short time, high efficiency, high precision and low cost, and it is suitable for mass production, but it is necessary to design a mold.
(3).NC numerical control blanking, NC is the first to write the numerical control process program, using the programming software, the drawing of the expansion map is written into the NC number drawing machine tool can be identified, so that the program according to these programs one step on the plate blanking the flat plate, but its structure is subject to the tool structure, low cost, precision 0.15.
(4). Laser cutting is used to cut the structure of the flat plate on a large plate by laser cutting. It needs to write a laser program like the NC material. It can lower the complex shape of the flat plate, and the cost is high and the precision is in the 0.1..
Sawing machine: mainly use lower aluminum profile, square tube, picture tube, round bar material and so on, with low cost and low precision.
Sheet metal processing cabinet cabinet is to be paid attention to:
1, the coating on the cabinet cabinet surface must be uniform, no flow hanging, the phenomenon of bottom.
2, the logo should be complete, clear and durable, and the serial number should not be missing.
3. Each panel of the cabinet cabinet must be smooth without distortion and distortion. The opening on the cabinet door should be uniform and neat.
4, the size should meet the requirements, the error should not be too large.
There are different factors in the quality difference of chassis cabinet. Because of different manufacturers' technology and different material selection, the quality of the chassis is different. Because of the different needs, the chassis cabinet also shows different types, but there are reasons for the difference. The quality of the cabinet of the sheet metal processing cabinet is different, the product at that level exists in the market. It is usually not necessarily the price when the technician is selecting material. It is only part of the reason and not all. For the technical personnel, they pay more attention to whether the material itself is up to the standard, and the manufacture of the cabinet cabinet. Generally, the material is made of steel. This material may rust because of the special reasons. It may not be checked by one by one in the selection and purchase of materials. It may be mixed with some defective materials in these materials.
