The methods for processing stainless steel parts to improve production efficiency and quality, and reduce worker labor intensity and production costs are roughly as follows: 1) Tool material selection Due to the high cutting force and high cutting temperature when processing stainless steel parts, the tool material should try to choose YW or YG carbide […]
The difficulties in processing stainless steel workpieces mainly include the following aspects: 1. High cutting force. The stainless steel workpiece has high strength, large tangential stress and large plastic deformation during cutting, so the cutting force is large. 2. High cutting temperature. The thermal conductivity of stainless steel workpieces is extremely poor, causing the cutting
1. Straight grain drawing on the metal surface refers to the straight-line texture processed by mechanical friction on the surface of the metal plate. It has the dual function of brushing scratches on metal surfaces and decorating metal surfaces. There are two types of straight line drawing: continuous silk pattern and intermittent silk pattern. Continuous
PVD (Physical Vapor Deposition) refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target material and ionize the evaporated material and gas, and utilizes the acceleration of the electric field The evaporated substance and its reaction products are deposited on the workpiece. 1. Prevent gas
Screw pumps are widely used in sewage treatment plants to transport water, wet sludge and flocculant liquids due to their variable volume transport, strong self-priming ability, reversibility, and ability to transport liquids containing solid particles. . The selection of screw pump should follow the principles of economy, reasonableness and reliability. If the design and selection
Screw pump, also known as “screw pump” and “Archimedes screw pump“. A pump that uses the rotation of spiral blades to cause the water body to spiral upward along the axial direction. The screw pump device includes three parts: the prime mover, the variable speed transmission device and the screw pump. It is specifically composed
Causes of tool chipping during CNC machining center processing 1. Feeding too fast causes the tool to chip. 2. Feeding too fast at the beginning of cutting causes the tool to chip. 3. Loose clamping (tool) causes the tool to chip. 4. Loose clamping (workpiece) causes tool chipping. 5. Insufficient rigidity (tool) causes tool chipping.
Reasons for machine collision caused by CNC machining center programming: Insufficient safety height or failure to set it. The tool on the program list and the actual program tool are written incorrectly. The tool length (blade length) and actual machining depth on the program sheet are written incorrectly. The depth Z-axis fetching and actual Z-axis
The reason why the workpiece in CNC machining center is overcut. Knife bounce, the tool is not strong enough and is too long or too small, causing the knife to bounce. The cutting allowance is uneven (for example: 0.5 on the side of the curved surface and 0.15 on the bottom). Improper cutting parameters (e.g.
Ductile iron is known as the “best of both worlds” metal, meaning that it has the strength of cast steel and the excellent corrosion resistance of cast iron. The advantages of ductile iron are as follows: 1. The strength of ductile iron is comparable to that of cast steel. Ductile iron has a higher yield
