       What points should be noticed in tantalum machining parts?

     The melting point of tantalum is 2980 C, which is only inferior to tungsten (3380 C) and its density is 16.67 g/cm3 which in commonly used refractory metals.Under annealing condition, tantalum has good plasticity, stable at high temperature, and can absorb and hold gas.tantalum has Acid resistant,It is a biological material.Tantalum is widely used in electronic, chemical, medical and other industries. At the same time, tantalum is also an indispensable material for making cemented carbide.

     Tantalum has high melting point and high density, and has good plasticity under annealing condition, and its performance is stable at high temperature.The annealed tantalum material is soft and tough, which will cause serious adhesion when cutting and cause the adhesion and wear of the tool.Especially when cutting speed is lower than 20m/min, the phenomenon of sticky knife and tearing is more serious. When the cutting speed is higher than 40m/min, the tearing phenomenon is greatly reduced.Cutting tools require cutting tools as sharp as possible and cutting speed should not be too low.Generally, cemented carbide is used as tool material, commonly used are YG8, YW2 and so on.The geometric parameters of the cutting tool are: gamma O=35o to 45o, alpha O=5o to 8O, r=90o, r=90o, r=5o, O1=-2o to 2O, B gamma =0.1 to 0.3mm, R epsilon, and the surface roughness of the front and rear surfaces are 0.16 ~ 0.32 Mu to reduce friction and knives. The choice of cutting amount is as follows: the car is c=30 to 70m/min, ap=5 to 8mm, f=0.2 to 0.4mm/r, the car, the semen car, the c=50 to 80m/min, AP less than 1.5mm, f=0.1 to 0.3mm/r.

      In cutting, the cutting fluid with cooling and lubrication should be used, and the flow rate should be sufficient.
