What should I do if the spindle sleeve of the turret milling machine does not rebound

The non-rebound of the spindle sleeve of the turret milling machine is usually caused by insufficient elasticity of the reset spring or mechanical jamming. It is necessary to check the condition of the spring, adjust the mechanical components or replace the damaged parts.

Insufficient spring force

Phenomenon: The spring ages or gets damaged, resulting in insufficient rebound force, and the sleeve cannot reset automatically.

Solution: Replace the main shaft reset spring and ensure that the new spring's specifications match those of the original equipment.

Mechanical jamming

Phenomenon: The moving parts of the sleeve (such as guide rails and bearings) get stuck due to insufficient lubrication or accumulation of impurities.

Solution

1.Clean the guide rails and bearings and remove impurities;

2.Check the lubrication system and replenish or replace the lubricating oil.

The preload force was improperly adjusted

Phenomenon: The preload of the main shaft bearing is too large or too small, affecting the rebound of the sleeve.

Solution: Readjust the preload of the bearing to the standard range.

Other possible reasons

Disc spring failure: If the relevant springs of the clamping device are damaged, they need to be replaced simultaneously.

Transmission component failure: Check whether the drive belt, couplings, etc. are loose or worn.
