一 . Introduction to the Important Structure and Function of The Stone Carving Machine
The structure of stone carving machine is complex, users should have a deep understanding, but even so, the use of stone carving machine is not difficult. In fact, many users do not know much about the structure and each part of the stone carving machine, so today's edition wants to introduce you to an important part of the stone carving machine.
Machine tool body is the structure entity of stone carving machine, which mainly includes main moving parts, feed moving parts (such as worktable, tool holder), supporting parts (such as bed, column, etc.).
In addition, CNC machine tools such as stone carving machines are equipped with cooling, lubrication, indexing parts, tool setting and measuring devices. Compared with ordinary machine tools, CNC machine tools have undergone great changes in overall layout, appearance modeling, transmission mechanism, tool system and operation mechanism, in order to meet the requirements of CNC technology and give full play to the characteristics of stone carving machine.
To sum up, it includes the following changes:
The stone carving machine adopts high performance main drive and spindle components. It has the advantages of high transmission power, high stiffness, good vibration resistance and small thermal deformation.
The feed drive of stone carving machine adopts high efficiency transmission parts. With the characteristics of short transmission chain, simple structure and high transmission accuracy, ball screw pair and linear rolling guide pair are generally used.
Stone carving machine has perfect automatic tool exchange and management system.
Stone carving machines generally have automatic workpiece exchange, workpiece clamping and loosening mechanism in the processing center.
Stone carving machine tool itself has high dynamic and static stiffness.
The stone carving machine adopts fully enclosed housing. Because the stone carving machine tool is automatically processed, in order to operate safely, it usually uses the fully enclosed cover of the movable door structure to completely enclose the processing parts of the machine tool. For semi-closed-loop and closed-loop stone engraving machine, there is also a detection feedback device. Its function is to detect the actual movement speed, direction, displacement and processing status of the machine tool, and to convert the detection results into electrical signals to feed back to the CNC device. The detection feedback devices mainly include induction synchronizer, grating, encoder, magnetic grating and laser range finder.
