Boring machine and drilling method

Abstract

This invention relates to a drilling machine, which comprises workpiece, driving unit, execution unit, controlling unit and energy supply unit according to the order of the controlling, dynamic and energy delivery, characterized in that inside the system it adds the vibrating unit, applying vibrodrill mode to process; the drill bit will do axial harmonic vibration except the ordinary rotating and feed. This invention also discloses a drilling method based on the said drilling machine, characterized in that when drilling, the drill bit will do axial harmonic vibration except ordinary rotating and feed.

Description

Technical field: [0001] The invention relates to mechanical design and machining technology, and in particular provides a drilling machine and a drilling method. Background technique: [0002] In the prior art, there have always been some big problems about the machining of tiny or deep inclined holes, such as the drill bit is easy to break, the life of the drill bit is low, the work efficiency is not high, or even cannot be processed at all, etc., especially It is especially difficult to process tiny and deep oblique holes in materials such as titanium alloys, stainless steel, and high-strength steel. [0003] At present, electrical processing methods such as laser beams, electron beams, and electric sparks are generally used to process such tiny holes. But the above processing methods all have their own defects. Processing methods such as laser beam, electron beam and electric spark drilling use light and electricity to generate high heat to melt or vaporize the material...

AI Technical Summary

Problems solved by technology

However, increasing the jig also brings many problems, such as the difficulty of alignment, the extension of non-processing time, etc.

Moreover, because the chip flute of the tiny drill bit is shallow, it is difficult to discharge chips. Adding a drill template is equivalent to deepening the drilling depth, further deepening the difficulty of chip removal. It is even more difficult to process difficult-to-machine materials such as stainless steel with ordinary twist drills. For example: for a part made of 9Cr18 (stainless steel type), 4 tiny deep oblique holes need to be processed on the part with a diameter of φ0.45 0 +0.02 mm, the hole depth is about 4~5mm, and the hole depth ratio exceeds 10 times. At present, electric spark drilling is used, and three sets of reamers are used for reaming at the same time. Finally, manual grinding is used to correct the flow rate, hole diameter accuracy and surface roughness. Unable to guarantee, the flow stability is poor, the flow dispersion is large, it is not suitable for control, and it is difficult to meet the design requirements
