One, fracture of wire 1.

Discharge condition not beautiful -- reduce P cost, if P value reduces scope bigger still fracture of wire, can consider to reduce I cost, till ceaseless silk. This operation can reduce treatment efficiency, if frequent fracture of wire, ask referenced and the following content, find out the prime cause that causes fracture of wire. 2.

Out of order developing fluid, if fluctuation nozzle cannot stick treatment, when open perhaps mode is machined, normally position of fracture of wire is machining area. -- reduce P cost, check mouth of fluctuation gush water to whether damage, if damage,change in time please. 3.

Electric conduction piece wears away serious or too dirty, normally position of fracture of wire is near electric conduction piece. -- rotate or change electric conduction piece, undertake cleaning. 4.

Seal wire ministry is too dirty, cause blow silk, normally position of fracture of wire is near seal wire ministry. -- clean seal wire component. 5.

Pulling force is too large -- the filar tension FW in moving low parameter, especially when taper cut. 6.

Quality of material of electrode silk, workpiece has a problem. -- change electrode silk, reduce P and I cost, till ceaseless silk. 7.

The waste silk in waste silk bucket spills over, with the machine tool or bottom surface contact, cause short circuit, just start treatment to be met normally fracture of wire. -- the bucket of waste silk of waste silk replace that will spill over, clear in time waste silk bucket. 8.

Receive filar annulus to be in fracture of wire -- check those who receive filar annulus to press silk to compare, mark fiducial value is 1: 1.

5 ~ 1.

6. 9.

Cooling water of electric conduction piece is inadequate, normally position of fracture of wire is near electric conduction piece -- loop of examination cooling water. 10.

Go ionic water conductivity is exorbitant, normally position of fracture of wire is machining area -- the conductivity that inspects water, be like out of tolerance, should change in time colophony. 11.

Go ionic water water quality is poor, normally position of fracture of wire is machining area. -- the water in cistern appears cloudy or peculiar smell, the clean water that perhaps adds a machine tool has a problem, should clear in time cistern, had changed filter paper core. 12.

Silk is pulled, place of next guide pulley of nose pottery and porcelain have waste silk to embed or movement of guide pulley bearing is ineffective vivid. -- clear and readjust installs guide pulley of pottery and porcelain, change when necessary guide pulley bearing. 13.

Balance annulus has shaken big, carry silk is not smooth. -- corrective silk fast, with tensiometer corrective silk tension. 2, treatment rate is low 1.

Did not press standard craft treatment, fluctuation nozzle is apart from workpiece prep above 0.

1mm -- stick treatment as far as possible. 2.

The craft file that found is incorrect. -- the treatment requirement related correct input, make reasonable craft file. 3.

Revised treatment parameter, reduced P, I to be worth overmuch meeting to bring about treatment speed to be reduced considerably especially. -- need parameter of craft of reasonable modification discharge. 4.

Out of order developing fluid, short of standard develops hydraulic pressure power. -- if cannot stick treatment really, need to know treatment rate correctly. 5.

Workpiece is out of shape condition of the discharge when bringing about treatment is not stabilized, repair especially cut. -- reasonable arrangement craft, control stuff is out of shape. 6.

If ACO chose in parameter (voluntary process is optimized) , in treatment the meeting below not stable circumstance reduces treatment efficiency. -- below the situation that stabilizes in cut, can cancel ACO function. 7.

More to corner work, parameter of use high accuracy can obtain taller precision, but can reduce efficiency. -- reduce cost of corner strategy STR appropriately, can raise treatment rate. 8.

Mode 30 treatment, discharge stability is bad, rate is slow-----Modification parameter UHP, can raise 2 costs. 9.

Long cut rate slow. -- can measure the opposite treatment of every knife make down a bit, if want to rise,repair cut the rate of one, but will advocate cut deflection measures make down 0.

005mm ~ 0.

01mm. 10.

Advocate be sure to cuts efficiency than before drop. -- undertake care and maintenance in time to the machine tool. 3, the surface has filar mark 1.

Electrode silk quality has a problem. -- the proposal uses the raw material that hold cost. 2.

Workpiece material problem, or material contains impurity. -- change workpiece material. 3.

Workpiece interior organizes local internal stress to release can cause work specific place has stria to happen. -- optimize treatment craft, reduce material interior stress to be out of shape. 4.

Working fluid temperature exorbitant or temperature change is too big. -- must control fluid with refrigeration machine lukewarm, and assure proper environmental temperature. 5.

The machine tool is exterior the environment is harsh, vibration is bigger. -- improve a machine tool external environment. 6.

Electric conduction piece wears away serious. -- electric conduction piece rotates or will change. 7.

Inadequacy of cooling water of electric conduction piece falls on. -- clean relevant component. 8.

Seal wire ministry is too dirty. -- undertake care and maintenance to seal wire ministry. 9.

Working fluid is too dirty. -- clear lotion chamfer and cistern, change working fluid. 10.

Observe whether discharge condition is stable, long whether to when cutting, short-circuit time cancel an appearance. -- if repair,cut have short circuit, can raise UHP cost 1 ~ 2. 11.

It is normal to if repair electric current of the discharge when cutting,reach voltage, but rate is very low. -- can reduce opposite deflection amount. 12.

Out of order developing fluid, short of standard sheds appearance to hydraulic pressure force and gush. -- on the examination, whether do next nozzle damage, if have damage, answer to change in time. 13.

Filar tension is flabby. -- calibration silk fast reach tension. 4, the surface is repaired not only 1.

Opposite deflection amount is too small. -- increase opposite deflection amount appropriately. 2.

Workpiece material is out of shape bring about long speed of the cut when cutting is inhomogenous. -- reasonable arrangement craft, reduce material to be out of shape. 3.

The quality of electrode silk is poor. The proposal uses the raw material that hold cost. 4.

Seal wire ministry is too dirty. -- undertake care and maintenance to seal wire ministry. 5.

Electric conduction piece wears away serious. Electric conduction piece rotates or will change. 6.

Craft parameter chooses a mistake. -- the treatment requirement related correct input, make reasonable craft file. 7.

Out of order developing fluid, short of standard sheds appearance to hydraulic pressure force and gush. -- on the examination, whether do next nozzle damage, if have damage, answer to change in time. 5, cut appearance error is big 1.

In the as a result of electrode silk lag when cut corner, can cause horny ministry dent. -- expensive to corner claimed accuracy work, should choose the parameter that has corner strategy. 2.

Be out of shape mediumly to reduce greater work to machine a process, can improve from treatment craft: (1) sunken model: Do twice advocate cut, first will advocate cut compensation increases unilateral 0.

1mm ~ 0.

2mm has first time advocate cut, let its stress release, quantity of reoccupy standard deflection undertakes the 2nd times advocate cut. (2) punch: 1) the allowance of of short duration that should leave two place or two place above, machine with opening type when process designing. 2) arrangement rises reasonably cut the position and the position that prop up. Dig bore a hole as far as possible, avoid from material exterior and direct cut. 3.

Silk is not perpendicular. -- undertake silk afresh corrective. 4.

The machine tool is exterior the environment is harsh, vibration is bigger. -- improve a machine tool external environment. 5.

Problem of quality of material of electrode silk, workpiece. -- the proposal uses the raw material that hold cost, data that does not have character issue. 6.

Position of workpiece outfit clip and fluctuation nozzle space are too large. -- adjust the method that hold clip. 7.

Silk fast or filar pulling force is not steady. -- adjust or calibration silk fast with tension. 8.

To fluid conditional happening changes apparently, cause filar vibration bigger. -- on the examination, mouth of water finishing in season, if gush water mouth damages, answer to change in time. 9.

Whether do the axis of the machine tool and fluctuation arm produce collision, cause mechanical precision to produce a change. -- if axis perhaps go up, next arms produce collision, cause precision unusual, answer to contact service personnel in time to undertake maintaining. 6, workpiece sunken heart or bosomy abdomen 1.

Among workpiece sunken heart: But will advocate cut reach repair cut parameter Ssoll the value is reduced, increase silk fast, tension, raise rate of cut of last knife constant speed, increase long 1 and advocate cut the opposite deflection amount between. 2.

Abdomen rouses among workpiece: The method of as sunken as processing workpiece heart is contrary. 7, differ in roll end diameter of straight body work 1.

The quality of electrode silk is poor. -- the proposal uses the raw material that hold cost. 2.

Optimize parameter. 1) raise filar rate, increase filar pulling force a little. 2) adjust parameter CCON. 3) when process designing, taper compensation is added in the program. 8, sunken model feed is in filar mark 1.

Use circular arc to be cut - circular arc cuts a way. When process designing, use circular arc to be cut - circular arc cuts a way, circular arc size is 0.

5mm can. 2.

Use cut - cut bit of detached way. When process designing, will every time feed place setting is in different position, avoid from same point feed, retreat a knife. CNC Milling
