Abstract
The utility model aims to provide a forcing chip breaking inner-cooling drill. Service life of the inner-cooling drill is prolonged, using cost is saved for clients, and work efficiency is improved. The forcing chip breaking inner-cooling drill comprises a handle part and an edge part, and the key lies in that the cutting surface of the end portion of the edge part is provided with a chip breaking groove. The cutting surface of the edge part is provided with the chip breaking groove, forcing chip breaking in a machining process can be guaranteed, and therefore the edge of the drill is protected. The edge of the forcing chip breaking inner-cooling drill is of a forcing chip breaking structure, and the edge is protected. Meanwhile, polishing is conducted on the chip breaking groove, the degree of finish of the chip breaking groove is improved, and chip discharging is facilitated. The drill cutting part is used for removing the spike effect, a coating covering surface is firmer, and the service life of the drill is prolonged.
Description
Technical field
The utility model belongs to cutter manufacturing technology field, specially refers to cold brill in a kind of forced chip-cutting.
Background technology
Drill bit is mainly used in the roughing in hole as an important component part in the machining usefulness cutter.Along with the development of mechanical industry, the user is to having proposed requirements at the higher level delivery date of the crudy of product, process reliability, working (machining) efficiency, cutter etc.The interior cold brill point of a knife of traditional design the continuous situation of iron filings the time occurs easily in boring, and sometimes even cause cutter to break, also having one is exactly that chip removal is not smooth, and coating covers insecure.
The utility model content
The purpose of this utility model is to propose cold brill in a kind of forced chip-cutting, with the service life of cold brill in improving, saves client's use cost, increases work efficiency.
Cold brill comprises shank and blade in the forced chip-cutting of the present utility model, and key is that the cutting face of described blade end is provided with a chip-breaker.Cutting face at blade arranges chip-breaker, can guarantee cutter forced chip-cutting in process, thus the protection cutting edge roundness.
Further, polishing is carried out on described chip-breaker surface, not only can reduce the roughness of cutter, makes chip removal more smooth and easy, but also can allow the cutting face of cutter remove the spike effect, makes the coating on cutter surface more firm.
The cutting edge of cold brill is taked the structure of forced chip-cutting in the forced chip-cutting of the present utility model; protected cutting edge; simultaneously chip-breaker is carried out polishing; improved the fineness of chip-breaker; be beneficial to chip removal; allow the cutter cutting tip remove the spike effect, make the coating coverage rate more firm, prolonged the service life of cutter.
Description of drawings
Fig. 1 is the structural representation of cold brill in the forced chip-cutting of the present utility model.
Fig. 2 is the structural representation of chip-breaker.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment:
As shown in Figure 1, 2, cold brill utilizes numerical control five-axle interlock grinding machine in the forced chip-cutting of present embodiment, independently writes knives routine and processes, and its matrix material adopts carbide alloy, and the surface is provided with the TIALN-H coating.Specifically, cold brill comprises shank 1 and blade 2 in the forced chip-cutting, and the cutting face of described blade 2 ends is provided with a chip-breaker 3.In the cutting face of blade 2 chip-breaker 3 is set, can guarantees cutter forced chip-cutting in process, thus the protection cutting edge roundness.
Further, polishing is carried out on chip-breaker 3 surfaces, not only can reduce the roughness of cutter, makes chip removal more smooth and easy, but also can allow the cutting face of cutter remove the spike effect, makes the coating on cutter surface more firm.
Claims (2)
1. the interior cold brill of forced chip-cutting comprises shank and blade, it is characterized in that the cutting face of described blade end is provided with a chip-breaker.
2. cold brill in the forced chip-cutting according to claim 1 is characterized in that described chip-breaker surface carries out polishing.
