Abstract
The invention discloses a kind of low-angle inclined hole processing technology, detailed process is as follows for the low-angle inclined hole processing technology: horizontal distance L, L=sin (α) the * h of the negative angle surface bottom and top that process needed for 1. being calculated according to the negative angle angle [alpha] of required processing inclined and the depth h of required cutting；Do not have to turn sequence again after the low-angle inclined hole processing technology clamped one time positioning, clamping is quick, high production efficiency.The processing method can make the three-axis numerical control of low-angle inclined hole process being easy for change.Inclined hole hole machined and its alloytype face position three-axis numerical control one-pass molding, machining accuracy are high.Without making tooling, turn five axis of sequence, processing cost is low, has more huge economic value and social value.
Description
Technical field
The present invention relates to inclined hole processing technique fields, specifically provide a kind of low-angle inclined hole processing technology.
Background technique
Currently, national three-axis numerical control equipment is generally more, general three axis of inclined hole production tooling is completed, or is turned sequence and set in five axis
Standby to complete, it is not only expensive that Five-axis numerical control milling machine belongs to high-end devices, but also processing cost is high, so would generally select three
Tooling belonging to a category is made on axis lathe.
Such processing method there are the drawbacks of be:
The position precision in hole is difficult to guarantee.It needs to turn sequence in process, from new Set and Positioning, so will lead to converted products
There is deviation in center.Difficulty of processing increases, and needs the linking of two processes, process-cycle to increase, influences processing efficiency.
People are highly desirable to obtain a kind of low-angle inclined hole processing technology that technical effect is excellent.
Summary of the invention
The object of the present invention is to provide a kind of low-angle inclined hole processing technology.The processing technology technique, changes
In enterprise production process, for, because some inclined holes need to turn sequence or production tooling, influencing processing in whole process and producing
The problem of precision of product, production efficiency, human resources are saved, reduced production cost, has substantially increased the profit of enterprise.

Its range of the tilt angle a of the low-angle inclined hole is within 25 degree, while the diameter d in hole is related to hole depth h
Connection.Bore dia d >=4L；Horizontal distance L=sin (a) the * h of the negative angle surface bottom and top that are processed needed for being calculated according to depth h；
Detailed process is as follows for the low-angle inclined hole processing technology:
1. the negative angle surface processed needed for being calculated according to the negative angle angle [alpha] of required processing inclined and the depth h of required cutting
Horizontal distance L, L=sin (α) the * h of bottom and top；
2. determining the two-edged slotting cutter of corresponding size according to L value, the head section diameter D of two-edged slotting cutter meets: inclined hole hole
Diameter >=25%D >=L；
3. selected two-edged slotting cutter is processed, the shank diameter size d after making processing meets (D-d)/2 >=L；
4. numerical programming program (along inclined hole center line) controls cutter and cuts along inclined hole center line.
5. the straight shank milling cutter after workpiece and processing is separately mounted on three coordinate machine bed, first workpiece is carried out in advance with drill bit
Drilling, the bit diameter≤(d-L) d are inclined hole diameter, and L is the horizontal distance of negative angle surface bottom and top；
The low-angle inclined hole processing technology is carried out fast using the three coordinate machine bed inclined hole workpiece shallower to low-angle
Speed, efficient processing.
Do not have to turn sequence again after the low-angle inclined hole processing technology clamped one time positioning, clamping is quick, production efficiency
It is high.The processing method can make the three-axis numerical control of low-angle inclined hole process being easy for change.Inclined hole hole machined and its alloytype face position three
Shaft and NC Machining Test one-pass molding, machining accuracy are high.Without making tooling, turn five axis of sequence, processing cost is low, has more huge economy
Value and social value.
