Abstract

The invention relates to drilling processing, and provides a micro hole processing device. The micro hole processing device comprises a high speed drill, wherein the high speed drill comprises a plurality of main shafts, a plurality of chipping suction covers, an electric control system and a cooling device, each chipping suction cover is provided with a dust collection pipeline, the cooling device is provided with a plurality of liquid guiding pipes, each chipping suction cover is provided with a liquid guiding pipeline, and each liquid guiding pipe stretches into the corresponding chipping suction cover along the corresponding liquid guiding pipeline. The invention also provides a micro hole processing method. The micro hole processing device is adopted by the micro hole processing method, and the rotating speed of a drilling tool is 15-120 Krpmin, and the feed amount of the drilling tool is 0.01-0.4 m/min. According to the micro hole processing device and the micro hole processing method, provided by the invention, the high speed drill is additionally provided with the cooling device, cooling liquid is guided into the chipping suction covers through the liquid guiding pipes, cooling and lubricating effects on the drilling tool can be formed, the broken rate of the drilling tool is greatly reduced, liquid accumulation is unlikely formed on a working platform, the rotating speed and the range of the feed amount of the drilling tool are limited when a micro hole is further processed, the drilling requirement can be met, and the broken rate of the drilling tool can be further reduced.

Description

Technical field [0001] The invention relates to drilling processing, in particular to a processing device for micro-holes and a processing method thereof. Background technique [0002] Due to the high hardness of the stainless steel plate, the drilling process is more difficult, which leads to the micro-hole processing on it, especially for the micro-hole processing of less than Ф0.8mm, the drilling tool must have a higher speed. Because the conventional micro-hole processing drill has a small diameter and low surface hardness, it is easy to break the drill tool. It is difficult for commonly used drilling rigs to meet the speed requirements for micro-hole processing, and PCB drilling machines are generally used for processing, which can obtain higher speeds. At the same time, due to the high heat generated during drilling and processing of stainless steel plates, and the exhaust cooling of conventional PCB drilling rigs is not enough to quickly reduce the high temperature produc...

Problems solved by technology

At the same time, due to the high heat generated when drilling stainless steel plates, the exhaust cooling of conventional PCB drilling machines is not enough to quickly reduce the high temperature produced by drilling tools, which can easily lead to drilling quality problems and drill tool breakage And other bad phenomena, which also makes micro-hole processing, especially in China, a current problem
