Q:Cubic boron nitride cutting tools for processing what materials

Suitable for machining high hardness materials and nonferrous metals

Q:What is the sintering and electroplating tools ah? What is the difference?

Sintering definition:Macro definition: at high temperature (not higher than the melting point), other key green ceramic particles, grain growth, voids (pores) and grain boundary gradually reduced by the material transfer, the total volume shrinkage, density increases, and finally become a dense microstructure of polycrystalline sintered body, this phenomenon is called sintering.Microscopic definition: solid molecular (or atomic) are attracted to each other, by heating the particles to obtain enough energy for migration, make the powder particles bond, produce strength and lead to the densification and recrystallization process called sintering.

Q:Processing about 60 degrees of material, what is good?

Cubic boron nitride cutter.High hardness steel castings casting forming, high hardness and difficult machining, casting surface roughness, especially large steel castings, casting defects may occur (such as hard, white, etc.) to meet performance requirements of tool materials such problems is very high. Cubic boron nitride cutting tool BN-S20 material can not only low speed, high speed machining of steel castings, but also large margin and intermittent cutting high hardness steel castings

Q:Open teeth is how one thing, the specific operation process.

Cutting tools require special tools to be polished, just like a tool.A tooth is in the part of cutting edge or polished into a jagged, double and single, full and half tooth tooth.

Q:Processing 316 stainless steel should be very sticky knife, how to choose the tool?

The processing of 316 stainless steel, stainless steel after quenching, and high hardness stainless steel imports, in addition to the use of high hard tools, processing stainless steel cutter to relatively sharp, preferably with the famous brand of special stainless steel cutter.

Q:What is the reference system of tool geometry?

Cutter angle reference systemThere are mainly three kinds of reference systems for cutting tool angles: the orthogonal plane reference system, the reference plane of the reference plane and the assumed working plane reference frame.The plane orthogonal reference system consists of a base of Pr, Ps and Po are cutting plane plane space three plane projection system called orthogonal plane reference system. Since the three projection planes of the reference system are perpendicular to each other, and meet the requirements of the three-dimensional Cartesian coordinate system, the reference system is the most commonly used reference system.Method: the plane reference system consists of base Pr, Ps and Pn cutting plane method of plane space of three plane projection system is called the method of plane reference system.The work assumes that plane reference system: the base Pr, it is assumed that the working plane Pf and plane back Pp space formed by the three plane projection system called assumed working plane reference system.

Q:What are the factors that affect the tool life

The material of the workpiece being machined.Better thermal conductivity of the workpiece material, by cutting away from the workpiece and by more heat, more conducive to reduce the cutting zone temperature, reduce wear of the tool workpiece; the hardness and strength of the material is high, the cutting force is greater, the greater the power consumption, the cutting temperature is higher, so that the tool wear.

Q:Turning steel pipe, what is good?

The following two kinds of cutting tools can be used for cutting steel pipe:1 if the hardness is low, so it is sticking to the knife on the lower, available hard alloy cutter "," turning speed is slightly higher, the appropriate amount of feed, the additional coolant side.2 if the hardness of the steel pipe is high or the knife is high, it is recommended to use the diamond cutter". High cutting speed, feed rate, side car additional coolant.

Q:What is the most important influence on the cutting tool?

The roughness usually requires the feed rate to be determined, so the parameters of efficiency and economy should be calculated according to the requirements of the drawing

Q:What is the role of shield machine tools

Profiling cutterThe shield machine is usually designed with two profiling tools (one spare), which are arranged at both ends of the spokes. During the construction, according to the requirements of over excavation and over excavation, the cutter can be extended out and retracted from the two ends of the spoke, so as to achieve the purpose of imitating cutting. The maximum value of the profiling knife is between 80 and 130mm. The shield machine advancing, on the curve turning or correction, by copying the overbreak cutting soil to create the necessary space, ensure the shield machine in the excavation on the surrounding soil, less interference under the condition of small curve and promote smooth turning and rectification, and the shield machine set profiling knife.
