How to identify the hardness and wear resistance of the toothed blade

Sufficient strength and toughness, machine knife material needs to have sufficient strength and toughness to withstand the high pressure of the toothed insert and to work under the shock and vibration conditions often occurring during the cutting process without causing chipping and breaking. 

High heat resistance and heat resistance are the main indicators for measuring the cutting performance of toothed insert materials. It refers to the performance of the toothed insert material to maintain the agreed hardness, wear resistance, strength and toughness under high temperature conditions. The toothed blade material should also have the ability to be easily oxidized at high temperatures and a good anti-adhesive and anti-diffusion ability, that is, the material should have good chemical stability. Good thermal physical properties and thermal shock resistance, the better the thermal conductivity of the toothed blade material, the easier the heat of cutting away from the cutting zone, which helps to reduce the cutting temperature.
