Q:What are the main factors that affect the quality of metal cutting?

It is of great significance to correctly understand the connotation of the surface quality of the parts and to analyze the various technological factors affecting the surface quality in the process of mechanical processing, to improve the surface quality and to improve the performance of the products.

Q:What is the difference between metal cutting machine tools and metal forming machine tools?

Metal cutting machine tools are cutting, grinding or special processing methods to process all kinds of metal workpiece, so as to obtain the required geometry, size, accuracy and surface quality of the machine tools (except hand carried).

Q:What is the arrangement principle of cutting order in machining?

First datum, then other.That is to say, we should first process the surface that is used as the base of the precision, and then finish the other surfaces with the machined standard as the reference.

Q:How about the metal cutting parameters?

According to the cutting force allowed by the process system, including the machine feed system, workpiece rigidity and surface roughness requirements during finishing, determine the feed rate.

Q:Causes of retention of mechanical metal chip cutters

In metal cutting, the reason why the cutting edge causes the accretion is that the cutting metal is formed by bonding with the tool before the high pressure and big friction force in the cutting zone.

Q:Method of programming for metal cutting machine tools

According to the processing mode is divided into 12 categories:Lathe, drilling machine, boring machine, grinder, gear cutting machine, thread cutting machine, milling machine, planer, broaching machine, EDM machine tool, machine tool, cutting, and other machine tools.

Q:What's the name of the machine that processes cutting tools?

Carbide cutting tools, mainly grinding machines, but also to use wire cutting equipment.

Q:What is the rigidity of process system in metal cutting?

When the lathe tool cuts the workpiece, the cutting forces on the cutting edge and the workpiece are affected by equal and opposite cutting forces, while the component Fy of the cutting force has the greatest influence on the machining accuracy. Under the influence of the cutting force, the tool (due to the deformation of the process system) and the relative decline of the workpiece.

Q:What is the relationship between metal cutting and numerical control machine tools?

You learn metal cutting completely, CNC operation is simple, mainly learning programming.

Q:What kinds of typical machine tools are involved in wood processing machinery? What's the difference between metal cutting and metal cutting?

Wood processing equipment and metal cutting equipment have similarities and differences. Common points are: both the main movement and auxiliary movement of the cutting process, and drilling machine and lathe is completely metal cutting equipment variation. The difference is: the cutting mechanism is different, the tool used is different.
