Abstract
The invention discloses a method for machining a deep stepped slotted hole. The method includes the step of classifying step cutters according to similar sizes. The method for machining the deep stepped slotted hole is characterized in that a step drill comprising a front drill bit with the size smaller than a slotting through diameter is adopted when a slotted portion is machined, a small guide hole is machined under the guide action of a large hole, chamfering is carried out under the guide action of the small hole, and the deep stepped slotted hole is finally reamed and formed in a classified manner. The method has the advantages that the machining takt time is shortened, the cost of the cutters is reduced, and the machining stability is improved.
Description
Technical field
The present invention relates to the hydraulic part field of machining, be specifically related to the processing method that a kind of dark step is crossed slotted eye.
Background technology
The processing of ladder cutter is generally adopted in the processing of crossing slotted eye for the dark step of hydraulic part for a long time, fraising can guarantee axiality so then, but when the cutter step is more not only cutter adjust difficulty, and when stepped hole differs bigger, the cutting speed of cutter is difficult for setting, and the hole step is more simultaneously, the chip removal difficulty, cause tool wear to accelerate, the cost of charp tool rises, and beat strengthens, and cutting is unstable.Realize low-cost cutting at a high speed based on above research by work step and cutter structure.
Summary of the invention
The objective of the invention is to improve beat in order to reduce the cost of charp tool, improve processing stability.
In order to achieve the above object, technical scheme of the present invention is as follows:
Dark step is crossed the processing method of slotted eye, comprises the step cutter is carried out classification by similar sizes.
Described dark step is crossed the processing method of slotted eye, it is characterized in that adopting when processing groove location anterior drill bit to bore less than the step that groove connects the footpath.
Described dark step is crossed the processing method of slotted eye, it is characterized in that macropore is the little pilot hole of guiding processing, with the aperture is being the guiding reaming, last classification ream moulding.
The beneficial effect that the present invention reaches:
1) shortens the processing beat;
2) reduce the cost of charp tool;
3) improved processing stability.
The specific embodiment
Dark step is crossed the processing method of slotted eye, comprises the step cutter is carried out classification by similar sizes.
Described dark step is crossed the processing method of slotted eye, it is characterized in that adopting when processing groove location anterior drill bit to bore less than the step that groove connects the footpath.
Described dark step is crossed the processing method of slotted eye, it is characterized in that macropore is the little pilot hole of guiding processing, with the aperture is being the guiding reaming, last classification ream moulding.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
Claims (3)
1. dark step is crossed the processing method of slotted eye, it is characterized in that comprising the step cutter is carried out classification by similar sizes.
2. dark step according to claim 1 is crossed the processing method of slotted eye, it is characterized in that adopting when processing groove location anterior drill bit to bore less than the step that groove connects the footpath.
3. dark step according to claim 1 is crossed the processing method of slotted eye, it is characterized in that macropore is the little pilot hole of guiding processing, with the aperture is being the guiding reaming, last classification ream moulding.
