Mould technology progress promotes report to machine the promotion of machine tool function

1 foreword in recent years the swift and violent development of mould industry, posed new challenge to mould technology. Electric spark is machined all the time since the core part that is mould technology, producing the effect that hold the balance in noting model moulding to build especially. At present the in progressing to had replaced a mould to make a few electric spark of technology of high speed milling machine working procedure, because this somebody thinks,its develop a trend to will replace electric spark treatment. But if be opposite,the advantage with respective technology of figuration of this two old patterns and inadequacy give serious analysis to be able to discover, because treatment of high speed mill suffers what milling machines means itself characteristic to restrict, it can not replace electric spark to machine in mould treatment. Narrow like deep chamfer seam, inside the clear treatment side clear part, arris, subtle, complex, accurate treatment, deep model the treatment of antrum, still have the treatment that exceeds hard data, these are the place that process capability place is deficient in high speed mill, treatment of contrary electric spark has absolutely advantage however. Additional, electric spark treatment falls in the effect that at present numerical control technology develops new condition, forward the numerical control of deeper administrative levels, higher level changes direction to develop quickly. Machine tool of electric spark of new-style nowadays numerical control emerges in endlessly, the function of the machine tool of numerical control electric spark of all sorts of brands had comprehensive promotion. The product of series of new fund SA with machine tool of scintilla of cipher telegram of essence of Beijing ACTSPRK numerical control is later development exemple (graph 1) , the property that in introduce machine tool of numerical control electric spark to be made in the mould, acquires promotes. Machine tool of electric spark of 2 numerical control is in series of SA of machine tool of scintilla of cipher telegram of essence of numerical control of graph 1 ACTSPRK the mould is made in obtained property promotes 2.

Of 2 treatment efficiency raise treatment of electric spark of contemporary mould requirement to improve efficiency of thick, finish machining considerably below the premise that assures precision. Wait for a domain like appearance of things of goods of mobile phone crust, home appliance, electric equipment, electron, ask the discharge time of workpiece of will large area shortens considerably, want to reduce surface roughness again at the same time. After the requirement discharges, some moulds undertake manual polish is handled no longer, this not only shortened handling time and the trouble of dispense with aftertreatment, promoted a mould quality at the same time. The requirement of these efficiency respects raised taller requirement to the function of machine tool of numerical control electric spark. Series of SA of machine tool of scintilla of cipher telegram of essence of ACTSPRK numerical control uses pure Switzerland to import pulse power source to make the productivity of treatment rises substantially. AEP is full automatic aggrandizement of process designing system the retrieval that machines a condition function, can undertake multistage the switch that machines a condition, through undertaking multistage the switch that machines a condition, can undertake each condition issues the treatment of optimal surplus, can shorten handling time, raise treatment precision. If use the red copper electrode of 20 ㎜ of Φ ,go up in 4Cr5MoSiV1 steel makings treatment 0.

5 ㎜ are deep, achieve lens side effect (make an appointment with Ra 0.

1 μ M) when be being used only 3.

5 hours (graph 2) ; When one antrum rough machining uses model of pen of transverse treatment Ha Fu 0.

8 hours, finish machining achieves Ra0.

Of 8 μ M bright and clean degree when be being used only 1.

2 hours. AEP is additionally full automatic the auxiliary time that process designing function reduced process designing, friendly man-machine interface makes the operation becomes very quick, also rose to machine efficiency on certain level. Machine tool of efficient numerical control electric spark is the capital that pattern company expands competition ability of market of market space, promotion, yi Yu of the new product that its are developed and becomes, new technology is welcome. Graph 2 lens face processes type graph 3 treatment breath out husband pen model 2.

Function had the increases machine tool of electric spark of current and advanced numerical control automation of 3 automation degree to rise in the round. Series of SA of machine tool of scintilla of cipher telegram of essence of ACTSPRK numerical control is optional match AEC (electrode exchanges unit automatically) place location system with fast outfit (EROWA, 3R) , treatment of so whole electric spark wants to load electrode knife library before treatment only, work out good machine program, can run automatically, use fiducial ball and measure a head to have fixed position, the carries out electrode and work place automatically measurement in treatment and amend, the treatment that monitor, need not operate artificially, broke a tradition to machine trival operation mode. The outside searching automatically center that additionally the machine tool has, search inside center, look for horn, electrode to look for axis of parallel, C automatically to rotate coordinate is fastened need not the automation that the function such as the successive treatment of corrective workpiece, many workpiece reflected Gao Shuiping of machine tool of numerical control electric spark.
