Abstract
The utility model relates to inner deep hole processing device, be made up of handle of a knife, main cutting edge, front cutting edge and helical flute, described main cutting edge, front cutting edge and helical flute adopt the machine-shaping of high-speed steel one, it is characterized in that: described main cutting edge, front cutting edge and helical flute are coaxially arranged, described helical flute is between multiple front cutting edge, and described helical flute is communicated to the end of handle of a knife by the end of front cutting edge.The utility model band helical flute, chip removal is unobstructed; Can reconditioning repeatedly; The utility model solves the unmanageable difficult problem of inside workpiece counterbore, simple to operate, long service life.
Description
Technical field
the utility model relates to a kind of cutter, is specially inner deep hole processing device.
Background technology
at present, reduce manufacturing cost become all trades and professions first will faced by problem, in machinery industry, under the prerequisite not affecting properties of product, reduce the consumption of material, that just reduces cost of goods manufactured, as: remove the excessive part in connection, directly process counterbore the inside of to be coupled, directly use bolt-connection, this kind of counterbore has certain difficulty in process.
Summary of the invention
the purpose of this utility model is to provide simple, the easy to operate inside deep hole processing device of a kind of structure, can overcome a difficult problem for inner counterbore processing, improve the working (machining) efficiency of such workpiece.
the technical solution of the utility model is: inner deep hole processing device, be made up of handle of a knife, main cutting edge, front cutting edge and helical flute, described main cutting edge, front cutting edge and helical flute adopt the machine-shaping of high-speed steel one, it is characterized in that: described main cutting edge, front cutting edge and helical flute are coaxially arranged, described helical flute is between multiple front cutting edge, and described helical flute is communicated to the end of handle of a knife by the end of front cutting edge.
the diameter of main cutting edge described in the utility model is greater than the diameter of front cutting edge.
operation principle of the present utility model is: by handle of a knife through counterbore bottom outlet, with the cutter bar clamping handle of a knife in machine spindle, starting device, while main shaft rotates, main shaft is to opposite direction feeding, and the main cutting edge of device and front cutting edge be cutting material simultaneously, thus reaches processing object; Main cutting edge and shank are in the same side, and device main cutting edge and front cutting edge can cut workpiece simultaneously, can cut by multiple-cutting-edge simultaneously, reduce cutting resistance, and band helical form chip area, chip removal is unobstructed, and available cutter and tool grinding machine is reused after carrying out reconditioning.
the beneficial effects of the utility model are: the utility model band helical flute, and chip removal is unobstructed; Can reconditioning repeatedly; The utility model solves the unmanageable difficult problem of inside workpiece counterbore, simple to operate, long service life.
Accompanying drawing explanation
fig. 1 is the utility model overall structure schematic diagram.
Detailed description of the invention
inner deep hole processing device, be made up of handle of a knife 1, main cutting edge 2, front cutting edge 3 and helical flute 4, described main cutting edge 2, front cutting edge 3 and helical flute 4 adopt the machine-shaping of high-speed steel one, it is characterized in that: described main cutting edge 2, front cutting edge 3 and helical flute 4 are coaxially arranged, described helical flute 4 is between multiple front cutting edge 3, and described helical flute 4 is communicated to the end of handle of a knife 1 by the end of front cutting edge 3.
the diameter of main cutting edge 2 described in the utility model is greater than the diameter of front cutting edge 3.
operation principle of the present utility model is: by handle of a knife through counterbore bottom outlet, with the cutter bar clamping handle of a knife in machine spindle, starting device, while main shaft rotates, main shaft is to opposite direction feeding, and the main cutting edge of device and front cutting edge be cutting material simultaneously, thus reaches processing object; Main cutting edge and shank are in the same side, and device main cutting edge and front cutting edge can cut workpiece simultaneously, can cut by multiple-cutting-edge simultaneously, reduce cutting resistance.
