How to calculate the production cost of CNC milling parts? How does non-standard trend milling parts attract customers? After milling, how can these parts be made into zero? What are the advantages? How to make these parts create zero and weld efficiently? How can these three zero items simply open the welding process? In essence, for most welding operations, the fixture is necessary for starting the welding process. The welding head does not require a welding post. The larger the welding hole after welding, the higher the weld spot reinforcement must be solved by using the fixture. During the half welding, the welding wire must also be used for processing.

The first steel pipe must be welded first, and the weld must be uniform. For the weld, it must be welded in advance. The weld must not be too thin, low current, uneven, or have cracks in the cylinder wall. For welded steel that cannot be used, if there are cracks, cut the small seam on the two metal plates and angle steel to be tangent to the two metal plates, causing cracks.

1. The welding seam should be controlled smoothly as much as possible, preferably through wire; The reserved welding line is positioned optimally (from the pole); When reserving a position; Welds should be as mobile as possible to minimize the probability of weld oxide.

2. Reserved welds and machined grooves; Reserved processing groove; Welding and beveling meet multiple requirements. After planing, they can have a certain roughness. After planing, they are prone to cracking. Before welding, the roughness of the groove is lowered. When cold welding a groove, the thickness of the production layer in the groove exceeds the thickness of the welding wire. At the welding repair site, there will be weld drops and penetration into the groove. Due to thermal deformation, cracking and loosening of the welding rod can also cause welding deformation.

Planing: Planing is the process of adding guided wedges to both ends of a concave tube to make contact with the outer diameter of the tube, blocking or pulling out of the hole to retain weld beads.

Grinding: Grinding is the process of using a file, grinding wheel dresser, grinder to deburr, reamer or reamer, and hydraulic or pneumatic polishing tools to remove surface roughness.

Vacuum pump manufacturers can also process various alloys, such as chromium steel, chromium vanadium alloy, cemented carbide, glass, ceramics, gemstones, and so on. This machine tool can also process various alloys, such as chromium stainless steel, nickel chromium iron alloy, chromium nickel vanadium alloy, and aluminum alloy.

1. Firstly, determine the process requirements of the parts and the batch size of the workpiece to be processed. The proposed function of the CNC lathe is to prepare for the early stage, and the prerequisite for the reasonable selection of the CNC lathe is to meet the process requirements of typical parts. The process requirements for typical parts mainly include the structural dimensions, processing range, and accuracy requirements of the parts. The control accuracy of a CNC lathe is selected based on the accuracy requirements, namely, the dimensional accuracy, positioning accuracy, and surface roughness of the workpiece.
