5results about How to "Smooth chip removal" patented technology

The application provides a special drilling tool for drilling a taper hole and a manufacturing method thereof, and steps are as follows: step 1, preparing a blank; step 2, processing a taper; step 3, processing a grinding groove; step 4, processing a main flank surface 2 of a chisel; step 5, grinding two main flank surfaces 1 of a drill tip; and step 6, grinding a first chip flute. The application is used for drilling a small inner hole and a large outer hole, effectively improves the drilling efficiency of the taper hole, and solves the processing problem of one-time forming of the taper hole.

The utility model discloses a kind of cutter structures of product end face roll diamond pattern, comprising: tool row, the inside of tool row is equipped with mounting hole, and the mounting hole both ends are adjacent to the two side walls of tool row and are penetrated;First mandrel, is set in the inside of mounting hole;Second mandrel, with the first mandrel side by side arrangement, and the second mandrel and first mandrel outer surface are all provided with knurling cutter;The utility model whole cutter is connected as rigid structure, easy to use, stable and reliable, part bushing end face knurling pattern can be forward and backward synchronous processing by two knurling cutters, guarantee pattern depth consistency, high efficiency, when replacing different products, tool row installation dismounting adjustment is convenient, knurling cutter height adjustment is also convenient, and adjustment effect is good, chip removal is smooth during processing, easy to use.

The utility model relates to the technical field of diamond saw blades, in particular to a multi-notch diamond saw blade. According to the saw blade, the open grooves formed between the adjacent diamond tool bits extend towards the center of the saw blade base body, chippings generated in the cutting process can be effectively contained, chipping discharging is smoother, cutting resistance caused by chipping accumulation is reduced, and therefore the cutting efficiency is improved. The lengths of the adjacent open grooves are different, stress generated in the cutting process is effectively dispersed, the stress is prevented from being concentrated in a specific area, and therefore the influence on the strength of the saw blade base body is reduced, the structural stability of the saw blade base body is enhanced, and the service life of the saw blade is prolonged.

The utility model relates to furniture processing technical field especially relates to a solid wood furniture punching device, including work table, the work table central position department is equipped with the through -hole that penetrates, the work table top is equipped with lifting mechanism, the working end of lifting mechanism installs board no.

The utility model belongs to the technical field of machining tools, particularly relates to a wear-resistant and heat-dissipation integrated composite coating inner-cooling drill, and aims to solve the problems that a drill body of an existing device rotates at a high speed to cut into a workpiece, the temperature of a contact area is sharply increased due to strong friction between a drill tip and the surface of the workpiece, and the drill tip is thermally deformed due to overhigh temperature; in order to solve the problems that in the prior art, drilling precision is affected, and tool abrasion is accelerated, the following scheme is provided: the wear-resistant and heat-dissipation integrated composite coating inner-cooling drill comprises a drill handle, a drill body and a guide part; the drill bit has the advantages that the spiral chip grooves form a concave-convex structure on the conical surface of the guide portion, actual contact area of the drill bit and a workpiece is greatly reduced, friction force and heat generated by friction are reduced, temperature of the drill bit can be reduced, thermal deformation is reduced, service life of the drill bit is prolonged, dimensional deviation of the workpiece caused by thermal expansion can be reduced, and service life of the drill bit is prolonged. And therefore, the machining precision of the workpiece is further improved, and the high-quality machining effect is achieved.
