What are the requirements for drilling tools for drilling?

Posted on

The bit is directly broken part of the rock, its shape, structure, material, processing technology, etc. directly affect the crushing effect and the life of the bit. The drilling requirements for the drill bit are:
Shape reasonable structure, high drilling speed, long life, wear resistance, sufficient mechanical strength, easy to insert the hard alloy, have good powder discharge performance, manufacture, easy disassembly and grinding, and low cost.

Sheet Metal Fabrication

Sheet metal fabrication processing is formed by laser cutting or stamping process, shear and bending, bending, bending, welding, riveting. The Sheet metal fabrication used are cold-rolled plate (SPCC), hot-rolled plate, galvanized plate (SHCC) (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum (5052), stainless steel. Sheet metal fabrication processing steps: according to the parts drawing (3D) expanded into a plan (2D), laser cutting or die stamping shape, CNC punching each bending part, should pay attention to the direction of the burr of the workpiece. Then the students are welded or riveted (some). Surface treatment after processing: electroplating, passivation, sand blasting (powder), anode treatment. Products are generally made for the connection and the outer cover. Applications in robotics, drone, communications, medical devices, industrial automation equipment.
