Problems solved by technology

[0002] Hole processing is very common in the mold manufacturing industry. In the process of deep hole processing, it needs to go through: drawing analysis—deep hole programming—deep hole processing—slow wire programming—slow wire cutting—slow wire repairing. A series of processes, this process consumes a lot of processing time, and each perforated fixed part takes about 30 minutes. At the same time, due to the loss of parts such as drill bits during processing, the processing cost is greatly increased. At the same time, the processing also requires Workers can only complete it manually and in cooperation with other processes. This processing method seriously affects production efficiency and increases the cost of manual processing. In order to solve this problem, ordinary mold factories usually choose drills for processing. During processing, it will cause excessive consumption of the drill bit, and at the same time, the drill bit processing cannot guarantee the accuracy of the deep hole. In order to solve the above problems, it is very necessary to design a drilling process

Embodiment

[0020] In the early stage of the process, we directly drill holes on the hard material surface, and the hole center is not allowed to deviate during actual processing;

[0021] Later, the plan was improved: the center of the hole was pre-drilled first, and then the drill was used to drill the hole. The centering drill played the role of guiding the drill to locate the center of the hole, and the effect was obviously improved:

[0022] A. Use a center drill to pre-drill the center of the hole to 2mm;

[0023] B. Use a drill bit to drill holes, exit the workpiece every 6mm and drill again to facilitate chip removal and protect the drill bit;

[0024] C. Do not penetrate when the drill bit is drilling, reserve 6mm on the bottom surface and do not penetrate;

[0025] D. Finally, a separate program is produced to directly punch through the hole;

[0026] The loss of the drill bit during solid drilling is not large, and the drill bit is easily damaged when drilling a hole. This me...

Abstract

The invention relates to a drilling process for deep hole machining for a hard material. A pre-drilling process is carried out at first, a pre-drilling bit is chosen to carry out pre-drilling on hole positions of a product, and during a pre-drilling process, tool setting is carried out at first, a pre-drilled hole with a depth of 0.5mm is machined for all the hole positions after the tool setting, foundations of the machined hole positions are moved by 0.5mm up and down after the operation is completed, the operation is repeated for many times, depths of 1-4mm, of the pre-drilled holes, are guaranteed, and pre-drilling operation is completed. The drilling process disclosed by the invention has the characteristics of avoiding breakage of the drilling bit, reducing a wear degree of the drilling bit and then lowering a production cost, omitting a wire wrapping process and then greatly increasing a machining speed of drilling, avoiding different hole diameters and then ensuring accuracy of the product, avoiding offset of the hole positions, and reducing consumption of the drilling bit and then prolonging the service life of the drilling bit, and the like.
