High-efficiency mesh drilling new method

Abstract

The invention discloses a high-efficiency mesh drilling new method. A workpiece to be processed is cylindrical, the method has the specific steps that S1, drill bits are aligned with each row of holeson the cylinder workpiece; S2, location holes are drilled: a hole with a certain depth is drilled on the surface of an unmachined cylinder workpiece by using a drill bit; S3, a main hole is drilled:according to the machining requirements, the drill bit in line with the hole diameter is selected, and the required hole depth is machined at the position of each location hole on the cylinder workpiece; when a certain amount of feed is drilled, the drill bits need to be retired for chip removal, reception is conducted, and the drilling of the hole is completed; and S4, pressure-relief holes are drilled: the pressure-relief holes with a certain depth are drilled at both ends of the cylinder workpiece by using the drill bit that is thicker than the drill bit drilling the main hole, when the workpiece with thousands of holes needs to be machined for several days in a row, once shut down or unexpected power off happens, run and machine directly as long as restarted, and the hole machined lasttime is continued to be machined.

Description

technical field

[0001] The invention relates to a new high-efficiency mesh drilling method, which is applied to mechanical processing in the field of equipment manufacturing such as automobiles, moulds, printing machinery, packaging machinery, food machinery, and aerospace. Background technique

[0002] In machining, when drilling a hole with a small diameter and a large depth, especially when drilling a hole on a steel part, there are usually the following main problems: difficulty in chip removal, difficulty in tool cooling, and easy skewing of the drilling axis. Whether these problems can be properly solved is related to the quality and productivity of deep hole processing, processing accuracy and thermal deformation of the tool, etc., and may even make the processing impossible. For example, when drilling a deep mesh, if the chips cannot be discharged in time, the chips may be blocked in the chip flute of the drill bit, which will not only affect the machining accuracy, ...
