Summary: Grinder of roller of HS403 of Italian Pomini company numerical control, measure the arm measures crural composition twice by E, Q, in using easy appear measure probe of grating of crural E, Q to be worth breakdown of data out of tolerance. Adopt doorsill of summary enlarge out of tolerance value, change measure officer of crural armature, air to measure the measure such as sensor of crural grating position and protective spacing component to have repair. Keyword: Grinder of numerical control roller measures brachial grating probe one, equipment of hot-rolling of 1880mm of breakdown treasure steel has grinding machine of roller of HS403 of company of 5 Italy Pomini numerical control. Measure a system to use independence to measure an arm configuration. In order to assure grinding and measure mutual hands-off, improve grinder efficiency. Measure the arm measures a foot twice to comprise by E, Q (graph 1) , by drive of synchronism of ball guide screw. Because high accuracy grinder is right synchronism sex demand is high, in using easy appear measure probe of grating of crural E, Q to be worth breakdown of data out of tolerance. 2, does breakdown case study cause the reason that measures probe of grating of crural E, Q to be worth out of tolerance to be: commonly? Ji  impossible is low doorsill of out of tolerance of value of probe of grating of Ning of beat of the circle that run strip putting in order, Q is worth a setting to father too. ② grinder E, Q measures a foot twice to get larger outside force, cause two measure a foot different situation, protect signal movement. The termination before ③ E, Q measures a foot twice touchs an odd side to wear away serious. The toggle switch setting that ④ grinder E, Q measures a foot to protect grating is too acute. Through be checked regularly and changing, probe is inhomogenous wear away to be able to avoid commonly. After the toggle switch that protects sensor presses drawing set commonly, the cover is surveying brachial case inside, cause trouble not easily. And setting of value of doorsill of out of tolerance is too severe, measure an arm to retroflexion frequent, measure a foot to suffer outside force or mechanical clearance to produce different situation, it is the main reason that causes this trouble. 3, breakdown means of settlement 1.

The measure that has installed Yan Cai to take in the light of value of doorsill of out of tolerance because roller diameter change is bigger, especially all-purpose grinder, tool change is frequent, still need to undertake holding the grinding of bearing box kind in the palm sometimes, can consider to magnify doorsill of out of tolerance is worth slightly. General but will relax to 1.

5 ～ 2mm (former 1mm) . Specific means can use SIEMENS process designing implement enter 840D HMI picture: F6 START UP F1 MACHINE DATA F10 User Data presses a picture on the right side of Search, key in MD_TAPERTHRESSHOLDF carriage return to affirm. MD_TAPERTHRESHOLDFORMANREALIGN numeric by 1 instead 1.

5 ～ 2, carriage return affirms. Press on SIEMENS interface set pushbutton again, let a machine tool remember revising. Undertake axis of artificial E, Q search afresh on grinder JOG interface finally ginseng. 2.

Measure the step that different situation takes the foot in the light of inside and outside (1) if inside and outside measures a foot to suffer outside force to be out of shape serious, must undertake machinery restores, direct even whole changes measure crural armature. Measure a foot to suffer such loss commonly, still need an examination to measure an arm level, perpendicular, check the status of the component such as component of spacing of sensor of position of torsional bedspring, grating, protection. (2) if inside and outside measures a foot to get outside force only minim is not synchronous (2 ～ 5mm) , but the basis measures brachial calibration lever, adjust directly measure the foot is measured inside the arm adjustment screw A (graph 1) . Measure a foot to contact calibration lever demarcate at the same time till two piece, can use 0.

The thin spacer help of 25mm increases adjust range; The relative position that should check the part such as protective spacing at the same time, checking a method is: Measuring the foot is mixed a small spacer is inserted between demarcate piece (ply about 1.

2mm) , adjust helix lever C, till movement of safe spacing switch. Attention, after should measuring a foot to be far from demarcate piece sometimes, the position that E axis and Q axis indicate is not 0. If produce this kind of situation, must undertake NCK replacement (NCK Reset Procedure) . NCK replacement measure is: Grinder is in park position urgently, press F10 key, by START-UP (begin to start) key, NCK is installed afresh, affirm with YES next, axial position by set. (3) the drop that causes as a result of reason of grinder itself machinery sometimes is different pace, the consistency of central line level that needs the center that adjusts calibration lever and roller will solve. The means of settlement is: Below the premise that makes sure inside and outside measures crural center to already agreed with roller center line, move measure brachial calibration order, make measurement unit fixed position is in demarcate piece place. Computation shows on CNC screen SERVICE the position of E axis and Q axis is poor. Adjust demarcate fast position to be worth till the position of E axis and Q axis identical. Differ around diameter the value to carry option of Caliper Preset Correction of grinder Machine picture again beforehand buy. Such value is greater, also can come true through revising corresponding MD. Also want to undertake NCK replacement finally of course. 4, manufacturer of machine tool of numerical control of experience brief summary undertook leaving factory installing to machine tool data, great majority is effective, but different operating mode and use condition undertake basis of user of need of data of bed of extension having a department optimize configuration again. Take the machine tool that surveys a system to should undertake mechanical, electric calibration to measuring a part regularly. CNC Milling
