Drilling
Drilling machining is the use of rotating drill bit to process the workpiece, the cutting edge part of the drill bit rotates on the workpiece while applying pressure at a constant speed to complete the diameter and depth of the hole.
Common drill materials include carbide, high speed steel, tungsten steel and ceramics. These materials have different hardness, wear resistance.Selecting the right bit and suitable machining parameters can better control the dimensional accuracy, perpendicularity and wall finish of the hole.
Always use reaming, boring or grinding as a secondary machining to bring the size and surface finish of the hole to a higher level
Drilling has an indispensable position in the manufacturing industry.
Processing & Standard
Common drilling processing is first based on the characteristics of the material, drilling depth, hole size, material hardness has been modulated, normalizing and other conditions to select the corresponding processing equipment and the correct tool deployment. For example, ordinary Q235, GR40, GR70, 16Mn, carbon steel, the material is soft, and the general twist drill can be processed, compared to F60, S316L, S2205 and other special materials need to use special tools (TDMX, TC4...)
However, it is always necessary to choose comprehensively according to the processing requirements, such as the hole diameter tolerance ±0.01mm, the inner wall finish of the hole Ra0.8~1.6, and the verticality of ⊥ Φ0.05 also need to be assisted by boring, reaming, grinding and other processes
