Enter processing program, workpiece is processed.
For the present embodiment lathe by taking certain gauge size as an example, processing semiaxis part major parameter is as follows:
1) range of work: the lathe is mainly used for processing the flange hole and threaded hole of all model semiaxis of semiaxis wire body, partly
Axis 600~1200mm of overall length, workpiece maximum flange excircle 250mm, minimum 131.2mm；
2) beat: R002 semiaxis (6 holes, unthreaded hole) series ≯ 46 seconds/root is processed, is clamped comprising fixture positioning, includes
Artificial loading and unloading；
HF17030 semiaxis (12 holes, unthreaded hole) series ≯ 75 seconds/root includes that fixture positioning clamps, above and below artificial
Material；
3) state before processing: before boring flange hole, semiaxis centre bore is machined in place.
Current similar Processes and apparatus mainly uses the forms such as vertical drill, multi-drill, numerical control drilling, and market general device is protected substantially
Precision is demonstrate,proved in 0.2mm or so.Present main engine plants, which require, improves semiaxis supporting part precision.Many enterprise requirements flange drillings position
Precision is set in 0.1mm, under conditions of using three-dimensional coordinates measurement, it is difficult to ensure that bore position precision is relative to centre bore and end face
Status requirement.The present embodiment lathe and similar product techno-economic comparison:
Similar Processes and apparatus for semiaxis drilling processing mainly uses vertical drill, multi-drill, numerical control drilling at present, lathe
Form, market general device basic guarantee precision is in 0.2mm or so.Driller center (vertical plus remodeling) currently used in the market,
Because not positioned using centre bore, although two pieces clamping, cannot can not be kept away in processing while workpiece loading and unloading, non-cutting time
Exempt from.Present main engine plants, which require, improves semiaxis supporting part precision, many enterprise requirements flange drilling position precisions in 0.1mm,
Under conditions of using three-dimensional coordinates measurement, it is difficult to ensure that bore position precision is relative to centre bore and the status requirement of end face.This
Lathe and existing market other equipment major technique, econmics comparison see the table below 1:
Table 1: this lathe and existing market other equipment contrast table
By comparing measuring and calculating, using this product compared with brill attacks center, by the factory for producing 1000000 abilities per year, every year may be used
To save production unproductive time 8330 hours.
The present embodiment processes semiaxis flange hole and threaded hole double-station lathe in the specific implementation,
What is be not specifically noted in all description of the invention is the prior art or can be realized by existing technology,
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description, and it is all this
A little modifications and variations should all belong to the protection domain of appended claims of the present invention.
