Abstract
The invention relates to a micro-hole grinding and drilling technology. The micro-hole grinding and drilling technology comprises the following steps: adding diamond particles or cubic boron nitride particles on a solid cylinder drill bit to form a grinding and drilling bit, determining the diameter of the grinding and drilling bit to be 0.2-0.7mm according to machining requirements, clamping and holding the grinding and drilling bit on a main shaft of a machine tool through a chuck, clamping materials to be machined on a workbench of the machine tool, and carrying out machining under the adjustment and rotation of the main shaft of the machine tool, wherein the rotation speed of the main shaft is 10000r/min, and the feeding amount is 0.001-0.01mm/r. By means of the micro-hole grinding and drilling technology, machining difficulty of holes is reduced, machining time is shortened, and working efficiency and machining quality are improved.
Description
Technical field
The invention belongs to mechanical processing technique, be specifically related to a kind of micro hole abrasive drilling technique.
Background technology
At some difficult-to-machine materials as titanium alloy, high temperature alloy, the Metal Substrate carbide composite material, the upper machining small such as carbon fibre reinforced composite, can adopt the methods such as laser, electric spark, drill bit drilling.But what these methods had will just can carry out being processed with under the specific (special) requirements condition, some working (machining) efficiencies are low, have to add cutter consumption in man-hour larger, cause the quality in the hole that processes not high enough, long processing time, difficulty of processing is larger.
Summary of the invention
The purpose of this invention is to provide a kind of on difficult-to-machine material the micro hole abrasive drilling technique of machining small, reach the difficulty of processing that reduces hole, shortened process time, improved the purpose of operating efficiency and crudy.
Technical scheme of the present invention: a kind of micro hole abrasive drilling technique, this processing step is as follows:
Set up diamond particle or the cubic boron nitride particulate is made the abrasive drilling drill bit on the solid cylinder drill bit;
Selecting available abrasive drilling bit diameter according to processing request is 0.2-0.7mm;
The abrasive drilling drill bit is clamped on machine tool chief axis by chuck;
By material clamping to be processed on platen;
Under machine tool chief axis adjustment rotation, processed, the speed of mainshaft is greater than 10000r/min, and the amount of feeding is 0.001-0.01mm/r.
Described abrasive drilling drill bit is by metal adhesive, diamond particle or cubic boron nitride particulate to be bonded on the solid cylinder drill bit.
Described abrasive drilling drill bit is by electroplating, diamond particle or cubic boron nitride particulate to be bonded on the solid cylinder drill bit.
The present invention compared with prior art has following beneficial effect: (1) the present invention reduces the difficulty of processing in hole, has shortened process time, has improved operating efficiency and crudy; The present invention can be on multiple difficult-to-machine material machining small, especially for the processing of the aperture on difficult processing metal, the aspect ratio aperture processing that realization that can be more convenient is larger.
