The ball screw cannot self-lock not because the friction angle is relatively small (it should be a large helix angle or lead angle), but because the transmission efficiency is too high (or the friction coefficient is too low).
The gantry planer is mainly used for planing large workpieces, and can also be used to clamp multiple parts on the workbench for simultaneous processing, which is the mother machine of the industry. The table of the gantry planer carries the workpiece through the portal frame in a straight reciprocating motion, and the idle stroke speed is greater than the working stroke speed. The beam is generally equipped with two vertical turrets, and the turret slide can rotate an angle in the vertical plane, and can make transverse feed movement along the beam.

Move the table to the innermost part, pad the grinding head with wood, and then remove the wire sleeve gear, and then take out the bearing.
Try not to remove the lead screw, because it is not easy to install!

Grinding machines are generally widely used in the construction machinery industry, and general grinders can be divided into cylindrical grinders, internal grinders, surface grinders, gear grinders, guide rail grinders, centerless grinders, tool grinders, etc., and the more commonly used in life are cylindrical grinders and surface grinders. It is widely used. Taiwan Jiande grinder is not bad. >>>More
