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.

In the process of mechanical processing, the commonly used methods for sheet metal cutting include manual cutting, semi-automatic cutting machine cutting, and CNC cutting machine cutting. Manual cutting is flexible and convenient, but it has poor quality, large size errors, large material waste, and a large amount of subsequent processing workload. At the same time, the labor conditions are harsh and the production efficiency is low. The profile cutting machine in semi-automatic cutting machines has good quality in cutting workpieces, but due to the use of cutting molds, it is not suitable for cutting single pieces, small batches, and large workpieces.
