Raceway diameter scope: φ 8.731 ~ φ 80mm;
Workpiece minimum outer diameter: φ 22.9mm;
Workpiece maximum outside diameter: φ 370mm;
Operating process of the present utility model is as follows:
Starting device, change the emery wheel 23 of corresponding specification, artificial material loading and clamping, manually tool setting, reset then, bistrique 9 vertical direction are stopped at the limes superiors position, and emery wheel 23 width median planes stop at workpiece 14 axial line positions, workbench 4 is stopped at workpiece 14 transpositions stopping position, and the diamond pen 5 of NC dresser 6 is stopped at finishing zero-bit vertically upward.
Automatically circulation time at first enters the finishing program.This moment, workbench 4 moved right, and made emery wheel 23 convergence trimmers 6.Bistrique 9 descends after arriving the X-axis trim bit, makes emery wheel 23 arrive Y-axis finishing start bit.Open grinding wheel spindle 24 then, grinding wheel spindle 24 horizontal (Z axle) was offset a setting value (correction side-play amount) forward after startup was finished, finishing is returned in the finishing campaign of the corner about 90 ° (angle can be set) of a direction of trimmer 6 beginnings again, stops up to the finishing zero-bit.Move a distance (twice correction side-play amount) then behind the bistrique 9, trimmer 6 rotates to other direction from the finishing zero-bit, returns finishing afterwards, stops up to the finishing zero-bit.The Z of grinding wheel spindle 24 is to resetting, and bistrique 9 goes upward to the surpassed distance position, the finishing EP (end of program).
Workbench 4 moves to left and arrives X-axis grinding start bit then, and bistrique 9 drops to Y-axis grinding and feeding start bit, begins reciprocal grinding program.
Back and forth during grinding, workbench 4 is finished once reciprocal, bistrique 9 feed compensations once or twice, until being ground to a certain setting size.Bistrique 9 rises to the surpassed distance position then, and workbench 4 is shifted to the right to workpiece 14 transpositions stopping position, and hand inspection ditch footpath and contact point determine that next step is to enter the finishing program or enter workpiece indexing program.
If enter the finishing program, then workbench 4 is shifted to the right to the X-axis trim bit, and bistrique 9 descends and enters Y-axis finishing start bit+correcting compensation amount, enters follow-up crushing program.Finishing is finished back bistrique 9 and is risen to the surpassed distance position, and workbench 4 moves left to X-axis grinding start bit, and bistrique 9 is got back to the mill amount of Y-axis grinding start bit+before this, begins grinding program.
If enter the transposition program, then start index table, workpiece 14 rotates 180 °.
Transposition finishes, and workbench 4 moves to left and arrives X-axis grinding start bit, and bistrique 9 drops to Y-axis grinding start bit.Begin reciprocal grinding program then.
After being ground to size, workbench 4 is shifted to the right to the workpiece transposition position of stopping, and bistrique 9 rises to the surpassed distance position.Circulation suspends, and carries out manual measurement and bistrique mill set positions eventually.
Setting finishes, and workbench 4 moves to left and arrives X-axis grinding start bit, and bistrique 9 drops to Y-axis grinding start bit, continues reciprocal grinding program then, until the size of setting of mill eventually.
After being ground to size, workbench 4 is shifted to the right to the workpiece transposition position of stopping, and bistrique 9 rises to the surpassed distance position.60 ° of workpiece transpositions.Bistrique 9 drops to Y-axis grinding start bit, and workbench 4 moves to left and arrives X-axis grinding start bit, begins reciprocal grinding program then, until the size of setting of mill eventually.
So grinding is finished in circulation six times (or eight times, ten times).Reset then.
Circulation suspends, the manual detection size.Determine whether to enter again the grinding circulation according to the size that detects.
If size is qualified, then artificial loading and unloading enter next circulation again.
If off-dimension, the artificial mill size eventually of setting enters grinding program once more.
