How to protect and extend the tool service life in the CNC machining operation(2)

- Mar 12, 2018 -

    In fact, the tools wear with geometry angle, cutting force, cutting heat and cutting amounts of these factors relations, so the durability and service life of the cutter can be extended by human subjective effort.

  • Improved tool geometry angle

    Cutter angle and the blade shape will directly affect the changes of cutting force. Such as: the front angle increases, the chip is small in deformation; cutting light, the cutting force and heat will drop. On the premise of guarantee the knife has enough strength, we should try to take larger front angle and increase the length of the blade for cutting, thus to make the cutting heat relatively decentralized and the cutting temperature will also drop.
