Common troubleshooting of deep hole machine tools B


Six, the blade has a short life and a cutting edge.

Cause analysis and measures:

A, low cutting speed, large feed. Increase the speed and reduce the feed.

B, the workpiece and the guide sleeve are not the same. Check the accuracy of the adjustment guide sleeve.

C, the cutting speed is too high. Reduce the speed.

D and guide keys wear too much; replace the guiding key or replace the guiding key material to improve its wear resistance. E, insufficient cooling flow and pressure, increase cooling pressure and flow rate.

Seven. The temperature rise of the spindle box is abnormal.

Cause analysis and measures:

A, insufficient lubricating oil or lubricating oil not to the lubricating point; check the oil quantity and lubrication point.

B, the bearing is too tight; adjust the bearing nut.

C, bearing improper selection, can not withstand high speed. Replace high speed bearings.

D,The bearing force of shaft is too large and the deformation is serious. Replace high stiffness bearings.

E, fuel tank heat dissipation is poor; instead of independent tank, increase the volume of oil tank or increase the oil cooler.


Eight. Abnormal gearshift of spindle box.

Cause analysis and measures:

A, control handle abnormal, transmission key or location key damage; replace damaged parts.

B, gear positioning abnormal; check gear position, replace damaged parts.


Nine. Abnormal gearshift of spindle box.

Cause analysis and measures:

A, control handle abnormal, transmission key or location key damage; replace damaged parts.

B, gear positioning abnormal; check gear position, replace damaged parts.


Ten, iron chip wound chuck body.

Cause analysis and measures:

A, iron scrap length, adjust cutting parameters, make iron scrap shorter.

B, cancel the chuck body, increase the spindle hole, and change the spindle hole to chip.

C, the workpiece is fixed and not rotated, and the tool rotates
