Abstract

The invention provides a method for machining a deep hole. The method includes the steps that firstly, a drill bushing hole is machined, wherein the drill bushing hole 3 is machined in the center of the deep hole 5 needing to be machined in a part 4 to be machined; secondly, a drill bushing is inserted, wherein the drill bushing 1 is additionally arranged and installed in the drill bushing hole 3, and the center hole 2 of the drill bushing 1 and the deep hole 5 are the same in diameter; thirdly, the deep hole is drilled, wherein a lengthened drill bit passes the center hole 2 of the drill bushing 1 to drill the deep hole 5 into required depth. By the adoption of the technical scheme, compared with the prior art, the drill bushing generates certain guiding and fixing effects on the drill bit, the phenomenon that the drill bit vibrates is effectively controlled, the requirement for the machining depth is met, the requirements for the location degree and the roundness of the machined hole are met, and the drill bit is prevented from being broken off.

Description

A kind of method of deep hole processing
Technical field
The present invention is a kind of method of deep hole processing, belongs to Machining Technology field.
Background technology
The situation needing drilling deep hole on product is often run in machining; because hole is darker in process; the length of drill bit is longer; beat is more serious; drill bit often can vibrate owing to locating inaccurate; make the deep hole position deflection of processing, size uneven, the situation of broken drill also occurs sometimes.
Summary of the invention
The present invention designs for above-mentioned the deficiencies in the prior art a kind of method providing deep hole processing just, its objective is and utilize drill bushing to create certain guiding and fixation to drill bit, drill bit is trembled be effectively controlled, ensure that the positional precision of machining hole and the requirement of circularity, prevent the generation of broken drill fault.
The object of the invention is to be realized by following technical measures:
The method of this kind of deep hole processing, is characterized in that: the method step be:
The first step, processing drill bushing hole, need center position processing drill bushing hole (3) of deep hole processing (5) at part to be processed (4);
Second step, diamond setting cover, add a drill bushing (1) and be arranged in drill bushing hole (3), the centre bore (2) of drill bushing (1) is identical with the diameter of deep hole (5);
3rd step, drilling deep hole, the degree of depth extremely needed by centre bore (2) drilling deep hole (5) of drill bushing (1) with lengthening drill bit.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the inventive method embodiment
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solution of the present invention is described in further details:
Shown in accompanying drawing 1, the method for this kind of deep hole processing, is characterized in that: the method step be:
The first step, processing drill bushing hole, need the center position processing drill bushing hole 3 of deep hole processing 5 at part 4 to be processed;
Second step, diamond setting cover, add a drill bushing 1 and be arranged in drill bushing hole 3, the centre bore 2 of drill bushing 1 is identical with the diameter of deep hole 5;
3rd step, drilling deep hole, pass through centre bore 2 drilling deep hole 5 of drill bushing 1 to the degree of depth needed with lengthening drill bit.
Technical solution of the present invention compared with prior art, drill bushing creates certain guiding and fixation to drill bit, the phenomenon that drill bit is trembled is effectively controlled, ensure that the requirement of working depth, ensure that the position degree of institute's machining hole and the requirement of circularity, prevent the generation of broken drill fault.
