As a kind of high speed, high efficiency, cost-effective production equipment, Full Automatic Hydraulic Machine is convenient to operate, simple process, to a great extent reduce labor waste. However, sometimes there will be faults such as unstable processing accuracy in internal or external situations, increasing the difficulty of problem elimination. Below, Yuhuan Yonggao summarizes several main reasons for the instability of machine tool processing accuracy to help everyone deal with it.

1, the workpiece size is accurate, the surface finish is poor

Fault cause: the tool tip is damaged, not sharp; The machine tool resonates and is not placed smoothly; Machine tool crawling phenomenon, processing technology is not good.

Solution: The tool is not sharp after wear or damage, then re-sharpen the tool or choose a better tool to re-set the tool; The machine tool has resonance or is not placed smoothly, adjust the level, lay the foundation, and fix smoothly.

The reason for mechanical crawling is that the guide rail of the drag plate is badly worn, the ball of the lead screw is worn or loose, the Full Automatic Hydraulic Machine should pay attention to maintenance, the wire should be cleaned after commuting, and the lubricating oil should be added in time to reduce friction; Choose the coolant suitable for workpiece processing, and choose a higher spindle speed as far as possible when it can meet the processing requirements of other processes.

2, the workpiece produces taper size head phenomenon

Fault cause: The level of Full Automatic Hydraulic Machine placement is not adjusted well, one high and one low, resulting in uneven placement; When turning a long shaft, the contributing material is relatively hard, the cutting tool is relatively deep, resulting in the phenomenon of letting the knife, and the tail seat thimble is different from the spindle.

Solution: Use the level to adjust the levelness of the machine tool, lay a solid foundation, fix the machine tool to improve its toughness; Choose a reasonable process and appropriate cutting feed to avoid cutting tool force, adjust the tail seat.

3, the driver phase light is normal, and the size of the workpiece processed is large and small

Fault cause: Full Automatic Hydraulic Machine drag plate long-term high-speed operation, leading to screw and bearing wear; The repeated positioning accuracy of the tool holder has a deviation in long-term use, and the drag plate can accurately return to the starting point of processing every time, but the size of the machined workpiece still changes. This phenomenon is generally caused by the spindle, the high-speed rotation of the spindle makes the bearing wear seriously, resulting in the change of processing size.

Solution: Use the dial indicator to lean against the bottom of the tool holder, and edit a fixed cycle program through the system to check the repeated positioning accuracy of the drag plate, adjust the lead screw clearance, and replace the bearing.

Check the repeated positioning accuracy of the tool holder with a dial indicator, adjust the machine or replace the tool holder; Use a dial indicator to check whether the workpiece is accurately returned to the program starting point, if possible, then overhaul the spindle and replace the bearing.
