Before crossing electric-hydraulic proportion valve regulation main spindle box, hoist cable oil cylinder amount of tension is to be applied to large floor boring and milling machine come the side of adjustment ram position
The conventional indemnifying measure of bed side's ram bending deformation.Its compensation process is similar to " the compensation of pitch error ", it is desirable to have certain technical ability
Human users, and very loaded down with trivial details：Firstly the need of the margin of error of 50 millimeters of spaced position when manually repeatedly measurement side's ram stretches out,
This error amount is manually entered by digital control system man machine interface and stores, then by digital control system inside PLC program conversion
After reason, offset is exported electro-hydraulic proportional valve, drive cylinder action to eliminate error.If configuring accessory head on square ram, because
Accessory head varies in weight, and when ram stretches out, deflection deformation degree is different, thus each accessory head to need independent measurement to go out corresponding
Error amount.Accessory head is more, and measurement, the data processing are also more.And, lathe is after trimming or through long-play
Afterwards, all parts relative position can change, and corresponding actual error value also can change, and is at this moment accomplished by all again
Measurement, and the old error amount update all that system is stored, such guarantee lathe has good machining accuracy.
