Coated tool features

The coated tool combines the advantages of high strength, high toughness and high hardness and wear resistance of the substrate, which improves the wear resistance of the tool without reducing its toughness. Wide range of coating tool versatility, the processing range significantly expanded, the use of coated tools can get significant economic benefits. A coated tool that can be used instead of several uncoated tools can greatly reduce tool variety and inventory, simplify tool management and reduce tool and equipment costs. However, after the tool is coated in the existing coating process, the coating material has a large internal stress due to the difference of the material properties of the coating material, the large internal residual stress of the coating, the low bonding strength between the coating and the substrate, the easy peeling of the coating, And the coating process also caused the matrix strength decreased, coating blade re-grinding bad, complex coating equipment, expensive, high process requirements, coating a long time, the cost of cutting tools and other shortcomings.

Three-sided cutter

Three-sided cutter, can be divided into straight-tooth three-sided blade and wrong tooth three-sided blade. It is mainly used in the horizontal milling machine step surface and one or both ends through the shallow groove. In addition to the three-sided edge cutter with the main cutting edge, the two sides also have deputy cutting edge, thereby improving the cutting conditions, improve the cutting efficiency and reduce the surface roughness value. However, after resharpening the width of the larger changes, three-sided inserts cutter can solve this problem.

Integral thread cutter with chamfer function

The overall thread milling cutter with chamfer function is similar in structure to the general one-piece thread milling cutter but has a special chamfering edge at the root of the cutting edge for machining the thread end chamfer while machining the thread. Machining chamfering in 3 ways, when the tool diameter is large enough, chamfer edge can be used directly out of chamfering, the method is limited to the processing of female thread chamfering. When the tool diameter is small, chamfering can be used to machine the chamfer by circular motion. However, the use of chamfer cutting edge chamfer cutting edge, pay attention to the thread cutting tool and the thread should have a certain gap, in order to avoid interference phenomenon. If the machined thread depth is less than the effective cutting length of the tool, the tool will not be able to achieve the chamfer function, so choose the tool should ensure that the effective cutting length and thread depth match each other.
