rough surface or smooth surface , no chamfer or good chamfer for CNC machining ?

Have you considered why the cnc quotation is so different when purchasing? i want make a reply according our experience . 1: rough surface for the products , i am no pictures show , because our factory no rough parts . 2:no chamfer , maybe everyone know , the sharge edge will hurt people ….

What are the advantages of Longitudinal lathes ?

Because the structure of the longitudinal lathes is different from the traditional CNC lathe, the processing efficiency and processing accuracy of the core machine are higher than that of the CNC lathe. The longitudinal lathes adopts two-axis arrangement of tools. This design greatly saves the processing cycle time. By shortening the tool exchange time between…

Advantages and disadvantages of powder spraying/coating

Advantages of powder spraying: a) High construction efficiency. For large-area operations, the construction staff can install multiple electrostatic spray guns and spray multiple at the same time, which can effectively shorten the spraying time and improve the spraying efficiency; b) Powder spraying is the corona discharge of the electrostatic spray gun to make the powder…

Uses and characteristics of tinned copper

Copper tin plating can deposit a layer of bright metallic tin on the surface of copper. Copper-based electroless tin plating solution is mainly used for electroless tin plating of copper to increase the welding performance and decoration of copper. Used in the electronics industry, household appliances, food packaging, with anti-oxidation, increasing the beauty of copper…

When designing a mold, what are the main points and difficulties of the design?

Key points: Analyze the product (specific material bai performance, appearance requirements, whether du undercut, whether there is a special process, whether the zhi type is defective) Difficulties: Improve mold life, control costs (the easiest to process), and have a comprehensive grasp of the best appearance of the product. Simply put, it is the design. The…

What is the difference between aluminum alloy hard oxidation and ordinary oxidation ?

The difference between hard anodizing and ordinary anodizing: Advantages of aluminum alloy hard oxidation: 1. The surface hardness of aluminum alloy after hard oxidation can reach up to about HV500. 2. The oxide film thickness is 25-250um. 3. Strong adhesion, according to the oxidation characteristics of hard oxidation: 50% of the formed oxide film penetrates…

What are the advantages of silicone molding ?

Vacuum injection molding, namely vacuum compound mold, also called silicone compound mold, needs to be applied to silicone mold. The castable is defoamed, mixed, preheated, and molded under vacuum conditions, and the process of secondary curing and molding is performed in a thermostat at 60℃-80℃ for 2-3 hours, and the imitation of silicone compound molding…

What are the advantages of wire cutting?

Advantages of wire cutting: 1. CNC wire cutting processing is contour cutting processing, no need to design and manufacture forming tool electrodes, which greatly reduces processing costs and shortens the production cycle. 2. Directly use electric energy for pulse electric discharge machining. The tool electrode and the workpiece are not in direct contact, and there…
