The machine body is the mechanical structure of the stone engraving machine, which mainly includes the main moving parts, the feeding moving parts (such as the work table, the tool holder), and the supporting parts (such as the bed, the column, etc.).
In addition, CNC machine tools such as stone stone engraving machines are also equipped with cooling, lubrication, indexing parts, tool setting and measuring equipment. Compared with ordinary machine tools, CNC machine tools have undergone great changes in overall layout, appearance, transmission mechanism, tool system and operating mechanism. The purpose is to meet the requirements of CNC technology and give full play to the characteristics of stone engraving machine.
To sum up, it includes the following changes:
(1) The engraving machine uses high-performance main drive and spindle components. It has the advantages of large transmission power, high rigidity, good vibration resistance and small thermal deformation.
(2) The engraving machine feed drive adopts high-efficiency transmission parts. The utility model has the characteristics of short transmission chain, simple structure and high transmission precision, and generally adopts a ball screw pair and a linear rolling guide pair.
(3) The engraving machine has a complete automatic tool exchange and management system.
(4) The stone engraving machine generally has automatic workpiece exchange, workpiece clamping and relaxation mechanism on the machining center.
(5) The stone engraving machine itself has a high dynamic and static stiffness.
