Function and structure: It adopts imporded high-quality tool steel,special cutting-tool.It is specially durable.The installation of the cutting tool can be adjusted. The cutting tool can be sharpened again and again.its use life is vary long. The moving cutting knife stand is a step designing to make cutting force resolve and increase the cutting force times. The material of the moving cutting knife stand is T7A high-quality tool steel.its hardness and softness is reasonable.it is not easily broken or worn.it adopts high-strength steel screw(8.8 grade)to fix is.the structure is fim and durable. The main body is Q235A thick-wall high-quality steel to avoid that the machine is used for machine is used for a long time and affect its mechanical performance. The axle core of the machine is finished processing once to ensure concentric circle and verticality error is not larger than 0.05mm.Each part has reference hole.Twice roughfinish and fine finishing are carried out. The part has strong changeability and high precision.
