Q:Introduction to metal cutting machine tools

Metal cutting machine is a cutting machine used to process metal parts of the working machinery. It is a manufacturing machine, also known as machine tools or machine tools, machine tools in China, often referred to as the habit.

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

Mechanical surface quality refers to the micro roughness of the machined surface after the machining, also known as roughness. The surface quality of the machined parts directly influences the physical, chemical and mechanical properties of the machined parts. The performance, reliability and life of the product depend to a great extent on the surface quality of the main parts.

Q:How is the cutting force calculated in a metal cutting unit?

The power consumed in the cutting process is called the cutting power Pm (GB Po). The cutting power consumption for Fz and Fx power and Fy direction without displacement, so no power consumption.

Q:Metal cutting machine tool manufacturing is mainly mechanical, machine, drilling machine, grinding machine etc.. Its safe operation

The metal cutting machine tool manufacturing machinery is all machines, lathes, drilling, mainly planer, grinder etc.. The common accident machine, foul workpiece and chip flying impact cutting and grinding burn injury fracture collapse.

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

First principal second:First, the main surface is processed, and then the minor surface is processed.

Q:Method of programming for metal cutting machine tools

According to the degree of automation: manual, motor, semi-automatic, automatic machine tools.According to the quality of machine tools: instrument, machine tools, medium-sized, large and heavy machine tools.

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

Welding tools such as cubic boron nitride and so on, and high frequency welding equipment.

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

The so-called process system stiffness, refers to the workpiece surface processing in the cutting force to the component Fp, the tool relative to the workpiece in the direction of the Y shift ratio: k=Fp/y

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

The most simple, wood processing and metal cutting are essentially different, the metal cutting process is the shear slip process of grain, so the characteristics of the decision and wood processing and inevitable differences exist, the principle of processing equipment.

Q:What are the unsafe modes of metal cutting machine tools?

No earthing protection,what is more,the rotating part has no shield.
