Attention Should Be Paid When Cutting Tantalum Sheets

2024-01-05 18:00:06

Tantalum sheet has high melting point, high density, good plasticity in annealing state and stable performance at high temperature. The annealed tantalum material is soft and tough, which will produce serious adhesion phenomenon in cutting and cause the tool bond wear. Especially when the cutting speed is lower than 20m/min, the phenomenon of sticking knife and tearing is more serious. When the cutting speed is higher than 40m/min, the tearing phenomenon is greatly reduced.

tantalum sheet

Cutting should be as sharp as possible, cutting speed should not be too low. Carbide is generally used as tool material, commonly used YG8, YW2 and so on. Using larger rake Angle and the Angle, cutting tool geometry parameter is: gamma 35 ~ 45 O, O O = alpha = 5 ~ 8 O, O O Κ r = 90 O, Κ 'r = 5 O, gamma O1 = - 2 O ~ 2 O, gamma = 0.1 ~ 0.3 mm, b r epsilon = 0.2 ~ 0.5 mm, surface roughness Ra< behind before; 0.16 ~ 0.32 m to reduce friction and adhesion.
