On the mechanical properties of the engraving machine and several factors that affect the carvings are?

Engraving machine mechanical properties as well as the influencing factors of sculpture carving machine including flatness, on the mechanical properties of the vertical degree between shaft and positioning accuracy, repetitive positioning accuracy, etc. Main impact plate flatness, artifacts, the difficulty of the leveling. Vertical degree between shaft mainly affect the size precision of workpiece, XY axis perpendicularity large is a rectangle is typical of a diagonal is not equal, the perpendicularity of the Z axis and XY plane is with flat bottom sword is typical of a large span larger milling plane, surface rough. Positioning accuracy affect the size error of workpiece, mainly depends on the precision of the leadscrew, compensation ability of the control system, the change of environmental temperature. When processing more than 300 mm, must consider the influence of the positioning precision of workpiece size. Repeat positioning accuracy main influence cutter machining, machining, etc. Engraving machine adopts roller screw drive, without crawling phenomenon, can realize micro feed. Repeated positioning precision mainly depends on the control accuracy, generally for two control resolution. Environmental factors that affect carvings include mainly includes the surrounding environment of power supply, vibration, temperature and humidity, dust, lightning, etc. The influence of power supply for processing is the most direct, main show is control system disorders. CNC control system of every feature of various electronic devices, there is a certain voltage and frequency range. Overload operation of any component parts inevitably lead to the instability of the whole system, common phenomenon is processing deviation. Influence of vibration is the knife is frequent, the surface is not smooth. Common reason is to touch in the manufacturing process of machine tools, machine tools installation levelness is unqualified, surrounded by punching machine. The influence of environment temperature and humidity control system of the performance, the performance of the drive motor. When the environment temperature more than 40 degrees, the control system control and possible errors and drive motor drive torque may reach rating. Dust main effect, heat dissipation and the sensitivity of the sensor of electronic components. Common phenomenon including light inspection failure, computer CPU fan does not turn, etc. The main factors influencing the material performance carving is the material type, hardness and toughness. Material categories including metal materials and nonmetal materials. In general, the greater the hardness, workability, the viscosity, the greater the processability. Impurities, the more processability, material particles, the greater the hardness, workability, the worse. A general standard is: the higher the carbon content, processability, the higher alloy content, workability, non-metallic element content is higher, the better processability ( But the amount of non-metallic in general materials is strictly control) Suitable for carving non-metallic materials including organic glass, resin, wood, etc. , are not suitable for carving non-metallic materials including natural marble, glass, etc. Suitable for engraving metal materials including copper, aluminium, mild steel hardness less than HRC40, not suitable for engraving metal materials such as hardened steel. Factors influencing the sculpture processing cutting tool including cutting tool materials, geometric parameters and grinding technology. Tool material is used in carving processing hard alloy material, it is a kind of alloy powder, the main performance indexes of the material performance is the average diameter of powder. The smaller the diameter, cutting tool, the wear-resisting, tool durability. Tool sharpness main influence cutting force. The smaller the knife is sharp, cutting force, processing more smoothly, the higher the surface quality, but the less tool durability. So, when processing different materials should choose different sharpness. When processing is soft and sticky material, need some sharp knives, when processing material hardness is bigger, to reduce the sharpness, improve tool durability. But not too blunt, otherwise the cutting force is too large, affect processing. Is the key element of a cutting tool grinding finishing grinding wheel mesh. High mesh cutting edge grinding wheel can be polished out more exquisite, can effectively improve the durability of cutter. Mesh high grinding wheel can be polished the surface more smooth after the knife, can improve the surface quality of cutting.
