Abstract
The invention relates to a numerical-control machining technique for an aluminum part shell. The machining technique comprises the steps that a numerical-control machine tool is used, and a blank of the aluminum part shell is fixedly clamped; and then rough machining and finish machining are conducted, cutting liquid is supplied, the machine tool is started to make a machining tool slowly approach the blank subjected to rough machining, and then the finish machining is conducted on the blank. Compared with the prior art, a user just needs to take down a workpiece, repeated disassembling and clamping through two machine tools are not needed, in this way, the number of times of clamping is reduced, and working efficiency is improved.
Description
Technical field
The present invention relates to a kind of numerical control processing technology, especially relate to a kind of numerical control processing technology of aluminum component housing.
Background technology
At present, in the process of producing aluminum component housing, the processing technology generally adopted is all generally first roughing on machine tool, and then uses machining center fine finishining, needs two lathes, two cover clamping devices, and needs twice clamping.This technique has obvious shortcoming, is summarized as follows:
A, two lathes: this technique needs to take two lathes, this is a kind of invisible waste.The lathe saved can be used in the processing of other products, increases the processing and manufacturing ability of producing line.The operator's operation of original needs, become now two people, such company needs how to pay wage to workman, increases enterprise operation cost.
B, twice clamping: workpiece twice clamping has several shortcoming:
One, need making two to overlap frock, making frock needs to produce relevant expense, increases the cost of Product processing:
Two: need a polygamy tooling, machine tool needs a set of, machining center also needs a set of, cause processing cost to increase, and the many inconvenient management of tool category, quantity;
Three: twice clampings increase machining time, and production efficiency declines.
The technical problem how solving above existence becomes one of present problem demanding prompt solution.
Summary of the invention
Object of the present invention is exactly provide a kind of clamping times that reduces, the numerical control processing technology of the aluminum component housing of increasing work efficiency to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A numerical control processing technology for aluminum component housing, adopts a number of units control machine tool, adopts following steps:
(1) blank of aluminum component housing is fixed to clamp,
(2) roughing: according to the automatic Choice and process cutter of housing profile to be processed, process tool slowly near blank, utilizes sensor to be input in the control system of lathe by the data of cutting by startup lathe after tool contact blank:
(3) fine finishining: open cutting fluid, starts lathe by the blank of process tool slowly after roughing, carries out fine finishining to blank.
In the roughing stage, the rotating speed of machine tool chief axis is 600-800r/min, and controlling the speed of cutter is that the speed of 5-8mm/s is processed blank.
Finishing stage, the rotating speed of machine tool chief axis is 1500-2000r/min, high-speed cutting, and controlling the speed of cutter is that the speed of 3-5mm/s is processed blank.
Finishing stage, the cutting fluid added is the commercially available trade mark is the cutting fluid of SPH-39, and the feed rate of cutter is 0.1-0.2.
Compared with prior art, workpiece only need take off by the present invention, do not need with two lathes dismantle back and forth, clamping, which reduces clamping times, improve operating efficiency, have the following advantages:
1, technique is simple: only need an operation card, operator also easily identifies;
2, processing cost is low: original needs two lathes, are first only needing one, save cutting fluid, the electricity charge etc.;
3, machining accuracy is high: the machining accuracy of machining center is high, this guarantees the machining accuracy of workpiece;
4, librarian use is few: original needs two operators, only need a people now;
5, working (machining) efficiency is high: the working (machining) efficiency of machining center itself is high, and does not need multiple clamping, dismounting workpiece, saves a large amount of time;
6, NC postprocessing degree is high: in process, operator does not need hands-on, alleviates the labour intensity of operator.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.
Embodiment
A machining center is processed, and workpiece is fixed by frock, fixture, is clamped by operator, then according to the profile feature of part, writes procedure, Choice and process cutter.Then start lathe, machine spindle speed 600-800r/min, move tool setting gauge with the speed of 5-8mm/s, by tool setting gauge slowly near workpiece, namely contact workpiece is passed to data in machine tool control system, and required cutter tool setting completes by same method successively.Subsequently machine spindle speed is adjusted to 1500-2000r/min, open cutting fluid, cutting fluid type adopts SPH-39, and lathe can perform instruction according to finishing numerical control program, does not need operating personnel's hands-on, now feed rate is F=0.1-0.2, treat program finishes execution, workpiece only need take off by operator, do not need with two lathes dismantle back and forth, clamping, which reduces clamping times, improve operating efficiency.Enumerate following data to be described:
Before not improving:
Class's output: 40/class, production cost: 18.5 yuan/part, workman's labour cost: 3.6 yuan
After improvement:
Class's output: 70/class, production cost: 11.5 yuan/part, workman's labour cost: 2.5 yuan
As can be seen from data above, after process modification, production efficiency improves a lot, and the quality level of product also improves, and scrappage declines, and production cost just reduces many accordingly.
