Abstract
The utility model discloses a PCD cutter in processing ring shape groove depth hole, cold hole in the terminal surface is equipped with before the cutter, the cutter tail end is ring channel and hole integration PCD, the ring shape slot part position of cutter tail end is equipped with interior cold hole to one side. The utility model discloses the main very low and processing circle ring channel of present processing technology efficiency of solving is out of shape great technical problem, and it has the machining efficiency height, the circle ring channel is good with the deep hole concentricity, and chip removal advantage such as effectual.
Description
Technical field
The utility model relates to the process tool technical field of annular groove deep hole type part, and specifically, what relate to is a kind of PCD cutter processing annular groove deep hole.
Background technology
In field of machining, the hole that often can run into some annular groove deep hole types needs processing, and the type annular groove and the usual concentricity requirement of deep hole very high.For the hole that concentricity requirement is high, our common way one first adopts cover lathe tool to process circular annular groove, and then with PCD (polycrystalline diamond) tool sharpening deep hole; Another kind is that the milling cutter first adopting diameter less first processes annular groove, and then with PCD tool sharpening deep hole.Above two kinds of process efficiencies are very low, and annular groove is out of shape, and concentricity is not easy to ensure; Like this, just can only put in place with the disposable processing of special type PCD cutter.
With above two kinds of methods processing annular groove deep hole, but two kinds of modes have following shortcoming:
1, cover lathe tool processing annular groove and deep hole substep are processed, and concentricity is overproof, causes annular groove to be out of shape; And working (machining) efficiency is low.
2, with the milling cutter processing annular groove that diameter is less, time, working (machining) efficiency is low, fractures and have obvious tool marks in groove in easily causing little milling cutter to be processed.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, there is provided a kind of PCD cutter processing annular groove deep hole, this cutter can solve existing processing technology efficiency very low and the hole of processing and the larger technical problem of annular groove Concentricity tolerance; Have that working (machining) efficiency is high, annular groove and deep hole degree good, and in the advantages such as intracardiac cold type bits are effective.
For realizing above-mentioned object, the utility model provides a kind of PCD cutter processing annular groove deep hole, described cutter front end face is provided with interior cold hole, and described cutter tail end is cannelure PCD integrated with hole, and the annular groove position of described cutter tail end is provided with cold hole tiltedly.
Preferably, described cannelure PCD integrated with hole, wherein the concentricity in annular groove and hole is within 0.01mm.
Preferably, the concentricity in described annular groove and hole is within 0.01mm.
Preferably, described Tool in Cutting sword top point of a knife exceedes the whole cutter centre of gyration, and center cutter can be avoided to cause excessive cutting resistance because linear velocity is low, and this resistance causes workpiece material to be out of shape and tool nose tipping.
In the utility model, there is interior cold structure at front end face and the tail end annular groove center of described cutter body, can easily chip when cutting, and fully can cool chip removal again.
The utility model beneficial effect:
1, the utility model cutter is when processing annular slotted eye, can ensure that the concentricity in annular groove and hole is within 0.01mm.
2, the utility model is when processing annular slotted eye, with normal PCD Tool in Cutting speed processing; Original scheme is completed by two tool sharpenings, and present one puts PCD tool sharpening in place, and working (machining) efficiency improves a lot.
3, the utility model cutter adds in front tail end intracardiac cold, ensure that processing dimension is stablized, improves product coarse rugosity and qualification rate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cutter front end and end construction schematic diagram;
In figure: annular groove PCD11 integrated with hole, cold hole 12, PCD blade 13 tiltedly, interior cold hole 14.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of PCD cutter processing annular groove deep hole, described cutter front end face is provided with interior cold hole 14, and described cutter tail end is cannelure PCD11 integrated with hole, and the annular groove position of described cutter tail end is provided with cold hole 12 tiltedly.
Preferably, the concentricity in described annular groove and hole is within 0.01mm.
Preferably, described Tool in Cutting sword top point of a knife exceedes the whole cutter centre of gyration (in figure PCD blade 13), avoids center cutter to cause excessive cutting resistance because linear velocity is low, and this resistance causes workpiece material to be out of shape and tool nose tipping.
In the utility model, there is interior cold structure at described cutter front end face and tail end annular groove center, can easily chip when cutting, and fully can cool chip removal again.
The utility model tail end is cannelure PCD11 integrated with hole, is applicable to processing annular groove deep hole type part, is specially adapted to process annular groove and the higher part of deep hole degree requirement.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
Claims (3)
1. process a PCD cutter for annular groove deep hole, it is characterized in that: described cutter front end face is provided with interior cold hole, described cutter tail end is cannelure PCD integrated with hole, and the annular groove position of described cutter tail end is provided with cold hole tiltedly.
2. the PCD cutter of processing annular groove deep hole according to claim 1, is characterized in that: described Tool in Cutting sword top point of a knife exceedes the whole cutter centre of gyration.
3. the PCD cutter of processing annular groove deep hole according to claim 1 and 2, is characterized in that: described cannelure PCD integrated with hole, wherein the concentricity in annular groove and hole is within 0.01mm.
