Cemented Carbide Tool Drilling Technology
Cemented carbide tool drilling process includes the method of covering with a metal cutting tool on the workpiece cutting a cylindrical bore.
Cemented Carbide Tool Drilling Technology |
Entity cemented carbide drilling is the most common tool drilling process drilling diameter of the hole should be determined in advance, and can be completed in a single step, in the solid material. |
Cemented carbide tool drilling process and follow-up related to the process, such as trepanning, reaming, reaming and boring. Common to all these drilling process combined rotation main movement and linear feed motion. Sets of holes are mainly used for large diameter holes, unlike entity drilling as the need to consume a large amount of power. The set of holes drilled is not the whole diameter of the drilling hole, but in the circumference of the hole on drilling a ring. It is not all the materials are removed to chip form, but left a core surrounding the center, therefore, such a drilling process is mainly used for through-hole applications; reaming is to expand the existing hole with a special tool, this the drilling process is cutting out a large number of metal; finishing reaming of existing holes in the periphery of the hole. This drilling process will remove a small allowance, so as to achieve a better surface quality and small tolerances.

With the development of modern shallow hole drilling technology, dramatic changes in the need for pre-processing and subsequent processing. Modern tool to make a the entity hole drilling can be done in a single step, and generally does not require pre-processing center hole or boot hole. Because of the good quality of the hole, so generally do not need to improve the measurement accuracy and surface quality reprocessed.
In some respects, the drilling can be compared with the turning and milling, chip breaking and chip requirements are relatively high, this is the most important for the drilling process. The drilling process is limited by the hole diameter and depth, the hole depth is greater control of the drilling process and chip requires more demanding. There are many parts need drilling shallow holes, the metal removal rate is higher than the quality and reliability of the hole.
