LHM type vertical honing the operation of the machine and the use
1 before starting the preparation work:
1.1 check hydraulic oil tank inside the hydraulic oil is added to the liquid level liquid temperature above the central part of the project, whether oil requirements, The first open oil surface should be higher.
1.2 check cooling fluid whether meet the requirements (plus JiXieYou, diesel oil or their mix the oil)
1.3 check the parts are complete, strong and reliable, pipe joints is already tightened.
1.4 check fixtures of adjustment and ground stem, whether it has the center axis superposition.
1.5 check the hydraulic system is functioning properly, hydraulic actuators are in place to correct.
1.6 check appliances control system is normal or not effective.
1.7 check every turn, whether good lubrication sliding parts, smooth operation, reliable.
1.8 check pressure gauge, electric lamps are normal work.
2 honing operating procedures:
2.1 measurement to the inner diameter of the steel tube mill size, sure honing surplus; Clean up the optimum scrap steel pipe inside and outside the sundry, remove pipe mouth burr.
2.2 according to the ground steel tube diameter and length, choose the appropriate positioning circle and tighten bolts will stay grinding steel pipe to the correct position clamping and strong.
2.3 according to the inner diameter of the steel tube ground, choose corresponding ground stem and grinding head each article sand bases, install a good ground stem.
2.4 according to the ground and honing steel making allowance requirements, choose the right into to speed up the pressure, grinding, expanding stem rotation speed, adjust set up.
2.5 according to the length of the steel tube ground, to adjust the trip length, make grinding head in the up and down limit when oil-stone show at each end steel making one-third to one 5 article sand long advisable.
2.6; Large steel tube workpiece honing, workbench exit, workbench the advance to the normal position honing, check the steel pipe center and ground stem center whether one.
2.7 will pack good article sand a (already rubber article sand) grinding head and ground rod connections, grinding head slowly close to steel tube and into the steel tube about half the length of the article sand.
2.8 start frequency conversion motor make grinding head spin, start stepping motor make up a expansion, the article sand, and starting to reciprocating oil cylinder into that grinding head start reciprocating motion, start cooling pump to steel pipe mouth and cooling fluid flow into the normal honing.
According to the work experience and 2.9 honing honing machining allowance, can operation panel counter on reciprocating number set honing, reciprocating number to, honing automatic stop, avoid excessive honing caused discarded product.
2.10 vertical honing machines starting, operation should pay attention to in the rotation, sliding positions may not have any objects and human body part has nothing to do exist, so as not to hurt and mechanical damage.
2.11 a honing machine cycle over, should quit grinding head in steel measured and prevent excessive honing steel scrap caused.
2.12 honing the measurement of exit to end or grinding head should first the grinding head back to the mouth, and loosen the push up, and then closed cooling pump and ground stem rotation motor, quit grinding head.
2.13 through the inner diameter measurements, such as not grinding to request, continue to meet the requirements of nangjing, finally polishing with emery cloth.
