Q: If the hardness is too high to bring the tool too brittle, metal processing of high hardness of the tool will bring any benefits.: The high hardness of the tool and the tool wear resistance are closely related (such as the surface of the abrasive wear, generally after the knife surface wear as a tool wear standard), good wear resistance, tool life is high. The high hardness of the cutting tool material, from the material properties of the workpiece is increasing, the most basic concept is: the hardness of the tool must be higher than the hardness of the workpiece, otherwise not cut.A good performance of the tool, only with high hardness is obviously not enough, but also has excellent comprehensive performance, including mechanical properties, physical properties and chemical properties. The mechanical properties of the tool generally include: high hardness, high toughness, high strength, high hardness (hardness); physical properties including tool: thermal conductivity, thermal expansion coefficient; chemical performance refers to the low affinity chemical tool and workpiece. In addition to consider the cost of diamond tools and PCBN cutting tool performance is excellent, the cost is very expensive.

Q: What is the difference between the choice of the angle of the rough and the fine?: It depends on the kind of material you are working on.The selection of the front angle: generally rough car to take a smaller front angle or negative rake angle, the purpose is to improve the cutting edge of the force and heat conditions, improve the cutting edge strength and impact resistance. In order to reduce the elastic and plastic deformation when the chip is cut off and the friction resistance between the chip and the front, the cutting force and cutting heat are reduced, and the machined surface quality is improved.After the selection of angle: rough machining, in order to ensure the strength of the cutter, choose the smaller angle; finishing, to ensure the surface quality, should be selected after a larger angle;The selection of the main deflection angle: roughing should choose a larger main angle, in order to reduce vibration, improve the durability of the tool and chip;The selection of the auxiliary deflection angle: the side slip angle should be smaller to reduce the residual area and reduce the surface roughness value;The choice of cutting edge angle: select negative value in roughing process, the purpose is to improve the heat dissipation condition and impact resistance, take the positive moment when finishing, improve the surface quality.

Q: What are the commonly used tool materials: The common tool material: high-speed steel, cemented carbide (including cermets), ceramic, PCBN (cubic boron nitride), PCD (PCD), its hardness is a hard, so in general, the cutting speed is higher than the one.

Q: Cutting tool materials: Other tool materials:(1) ceramic cutting tool: a kind of cutting tool made of alumina (Al2O3) or silicon nitride (Si3N4) as matrix, and then adding a small amount of metal at high temperature.(2): artificial diamond is an allotrope of carbon, is currently the most hard tool materials, the micro hardness is 10000HV.

Q: What is the classification of the hardness level?: Hard alloy tool hardness is generally between HRA89.5~92.8, the hardness of HSS is generally between HRC62~65, super hard high speed steel hardness is between HRC69~70, the hardness of carbon tool steel in general about HRC62, the hardness of diamond in the HV10000, the hardness of silicon carbide in HV4500, titanium carbide coating hardness HV3800, corundum hardness in the HV2400, tungsten carbide hard alloy hardness in 1300.

Q: Open teeth is how one thing, the specific operation process.: Open? It is wateredAfter the general tool blank out need grinding edge, look at what you have in front of the cutter, angle, mainly to prevent the cutting tool when there is a collision, but also to sharp, generally open the sharp angle better, but life is relatively short, 5-10 degree can be looked at to. The

Q: What are the causes of tool wear and breakage?: The tool wear is mainly divided into abrasive wear, chemical wear and so on. In general, the main reasons are different, such as abrasive wear is generally considered to be normal wear and tear, is due to the friction between the tool and the material being processed

Q: What is the relative motion between the tool and the blank?: 1 processing of standard gear: standard rack cutter indexing line and the blank of the dividing circle tangent and do pure rolling2 (processing) into the gear: standard rack cutter line deviation from its pitch line a bit XM, the line and the blank of the dividing circle tangent and do pure rolling.Problems can contact, hope to adopt.
