There are two ways to support the ball screw pair of a desktop stone cutting machine on the workbench. One form is a single support; Another form is the support at both ends. The desktop stone cutting machine clamps the outer rings of a pair of tapered roller bearings and pre tightens them to improve the rotational accuracy of the bearings, increase the rigidity of the bearing device, and reduce the vibration of the bearings during machine operation.

The double piece desktop stone cutting machine has a staggered tooth clearance structure with circumferential springs. Two thin desktop stone cutting machines are set together, and each desktop stone cutting machine has two circumferential grooves. Short columns are installed on the end face of the desktop stone cutting machine to install springs. When assembling, ensure that the spring has sufficient tension to make the left and right sides of the two thin table stone cutting machines tightly adhere to the left and right sides of the wide table stone cutting machine, in order to eliminate the gap on the tooth side.
