Calculations of cutting conditions
Product attributes
Straight shank with clamping flat (Weldon) according to DIN 6535 HB.
Helix angle = 44-46°.
Rake angle = 15°.
End face design - radius
With coolant holes
ta-C coating is designed for machining non-ferrous metals, aluminium alloys with higher Si content, copper, brass, bronze and plastics. Due to its small thickness, very low coefficient of friction and low tendency to stick, ta-C coating is suitable for materials with a tendency to stick as it prevents build-up on cutting edges.
For machining of soft materials, for example aluminium and non-ferrous metals.
Feed direction possibility
Oil coolant.
Carbide materials are characterised by high compressive strength, high hardness and therefore high wear resistance, but also limited flexural strength and toughness.
