XK2414 × 80 model trouble removal of workbench of milling machine of boring of door of numerical control dragon

001mm, every 200mm distance has one to labelled at 0 o'clock, overall length of workbench lathe bed 16.

5m, means of two joining together. 1. Breakdown phenomenon machine tool is being finished after removing first when electrify is debugged, numerical control system can be started normally, drive also can normal electrify, below REF mode of operation, it is normal that Y axis and Z axis clear, but X axis cannot be finished clear movement, in + X direction suspends campaign after mobile 200mm, the machine tool appears 20002 call the police: Channel 1 Axis X Zero Reference Mark Not Found (passageway 0 referenced mark did not find the X axis of 1) . 2. The largest space between the 0 mark that trigger of definition of 34060 REFP_MAX_MARKER_DIST(of data of machine tool of breakdown analysis examination is started and follow) set value, former set value is 200, theoretic X axis every shift 200mm is sure through labelling at 0 o'clock (every 200mm has one to labelled at 0 o'clock on grating feet) , data of modification machine tool has one to labelled at 0 o'clock inside the 34060 distances that are the 300 shift when ensuring X axis clears, breakdown did not remove. Below JOG mode of operation, can regular point uses rod of X, Y, Z, laser detects the fixed position precision of X axis and relocation precision, it is in machine tool limits. Below AUTO mode of operation, machine program cannot move, machine tool data 20700 by 0 long instead 1 (definition machine tool need not clear to be able to implement machine program automatically circularly) hind, machine program can move automatically, but use G code (G54-G59) the workpiece coordinate that builds is incorrect, the machine tool is other the function is normal. Classics above is checked and check, considering this fault is to happen after the machine tool removes first electrify debugs a state next occurrence (it is means of two joining together as a result of the lathe bed of workbench of this machine tool, grating feet is fixed go up in two lathe bed, when carrying, must bring grating rule first take out from inside grating feet box, tear open grating feet box below, wait for lathe bed to remove after installation has been adjusted, bring back grating feet again in installing grating feet box) , on purpose is initial decide cause axis of machine tool X to clear the reason of breakdown is: When the machine tool removes, bring grating rule be taken out from inside grating feet box and answer the attaint when outfit its 0 mark. 3. Trouble removal checks grating feet area, discovery has on grating feet belt smeary with scratch trace, after cleaning, answer outfit still cannot remove breakdown, grating feet takes physics to injure cannot repair. To eliminate fault correcting machine tool quickly investment is produced (buy grating feet newly to need 1 ～ of 3 months order goods periodic) , instead of axis of decision general X half closed circuit, information of feedback of coder of the buy inside electric machinery of servo of use X axis makes positional ring, the method is as follows. (The data of 34200 machine tools of axis of 1) modification X (by 3 instead 1) , the area of return-to-zero mode instead of X axis spacing hits a return-to-zero mode. (2) is made and install machinery to bump piece, increase a spacing journey switch that puts in small incidental expenses 's charge, adjust spacing journey switch and machinery to bump piece the position, the input signal of switch of join spacing journey inputs module to the DMP of PLC. (3) uses STEP7 software to modify PLC program, read the input signal that take and processes spacing journey switch, will the 2nd survey a system effective instead the first survey a system effective. Use STEP7 software revises FC30 functional piece content is as follows: M009: S M59.

1 (X axis feed makes can, the machine tool prepares to clear) A 137.

7 (read the input signal that takes spacing journey switch) =DB31.

DBX12.

7 (begin to search 0 pulse signal) R DB31.

DBX2.

1R DB31.

DBX21.

7R DB31.

DBX1.

6 (the 2nd measure a system to disable) S DB31.

DBX1.

5 (the first survey a system effective) (the data of 32700 machine tools of axis of 4) modification X (by 1 instead 0) , the pitch error that cancels X axis is compensated (the ability when complete closed circuit needs) , the Backflash that measures the backlash of X axis to compensate X axis (0) in. (5) adjusts X axis data of relevant machine tool, the system that reduces X axis checks precision, be worth the data of 36400 Contoures Tol of X axis by 0 original.

02 adjust for 0.

03, be worth the 36030 Standstill_pos_Tol data of X axis by 0 original.

02 adjust for 0.

03, eliminate the system after changing half closed circuit by complete closed circuit 25050 (Axis X 1 Contourmonitoring) and 25040 (Axis X1 Standstill Monitoring) call the police twice. Solved XK2414 × quickly through above measure 80 model the breakdown of milling machine of key of door of numerical control dragon, although the precision of axis of machine tool X drops somewhat, but the machine tool is main functional rehabilitate is normal, and the bogie structural frame that precision of the machine tool after repair satisfies AC locomotive of car of engine of Shaoshan series electric power, subway, high-power completely board makings 10.

The treatment craft of 5mm asks. Axis of machine tool X changes half closed circuit to use already had a year, it is normal that the machine tool is used. CNC Milling
