Problems solved by technology

[0002] At present, the drilling tools used in machining are composed of chisel edge, cutting edge, helical cutting edge, and side edge. The cutting edge is on a helical cutting surface and has a single co-position cutting structure. Inside, the cutting edge is subjected to the rotating cutting force and the outward conduction force from the center at the same time. Under the action of the double force, the cutting edge at the intersection of the cutting edge and the helical cutting edge is always very easy to be damaged. It is not absolutely balanced and there is a swing phenomenon. Simply relying on the helical cutting surface to stabilize the tool causes damage to the helical cutting surface and the helical cutting edge. It is generally understood that the smoother the surface, the higher the strength. High, none of the essential structural properties of the substance are revealed, therefore, the existing hole machining tools are low in efficiency, easy to damage, poor in stability, and poor in drilling accuracy

Abstract

The invention provides an alloy tool bit twist drill, and mainly relates to a drilling tool used for machining. The tool is high in stability, high in heat dissipation efficiency, long in service lifeand easy to position during drilling machining. The alloy tool bit twist drill comprises a tool handle, a spiral tool body and an alloy tool bit, and under the condition of the same material, the alloy tool bit twist drill is applied to millimeter strength; the strength of the alloy tool bit twist drill on the millimeter scale is at least improved by 50% or above compared with that of a twist drill of a common structure, and the average pressure borne by a cutting face of the alloy tool bit twist drill on the millimeter scale can be improved by 50% or above.

Description

Technical field: [0001] The invention relates to an alloy cutter head twist drill, the alloy cutter head twist drill is used in the drilling and milling process of mechanical processing and fitter maintenance. The new mechanical processing theory believes that the cutting efficiency of the segmented or stepped cutting edge is high, but when the stepped After the cutting edge is gradually extended, the effect will be significantly reduced until it disappears, so this theory is still not really a correct theory. Background technique: [0002] At present, the drilling tools used in machining are composed of chisel edge, cutting edge, helical cutting edge, and side edge. The cutting edge is on a helical cutting surface, showing a single co-position cutting structure. Inside, the cutting edge is subjected to the rotating cutting force and the outward transmission force from the center at the same time. Under the action of the double force, the cutting edge at the intersection of ...
