How to choose engraving machine?
- Select the model:For example, in the industry mainly engaged in wooden doors, doors and windows, the domestic plate is generally 1220*2440mm, so it is necessary to choose a suitable engraving machine, such as Excitech 1325 engraving machine. If the process is complex, such as engraving patterns and reliefs on doors, and more tools are needed to complete the work piece, you can choose automatic tool changing equipment, which is generally 2-3 times more expensive than ordinary machines (here, it is necessary to remind the spindle motor *.For machining cylindrical or other special-shaped work pieces, such as table and chair legs, stair handrails, bathroom sanitary ware, casting, automobiles, yachts, wind power generation, rail transit and other curved surfaces, five-axis and five-linkage machining can be selected.Heart, such as the bridge-type large gantry five-axis machining center produced by Excitech CNC; If you are a furniture maker and need to process wood reliefs in batches, you should choose a multi-head woodworking engraving machine or a multi-head lathe bed mobile machining center: if the carved wood board material is relatively large, if the fixture is used around it, the middle of the material will bulge out, resulting in different depths of carving, so you can choose a woodworking engraving machine with a vacuum adsorption table (there is a special stone carving machine for carving stone; There are jade carving machines for carving jade); If it is mass production of panel furniture, panel production line equipment can be selected. For example, excitech CNC is a plate-type production line which is composed of computer board saw, PTP single-arm router and milling center, automatic loading and unloading equipment and so on, and integrates “design, production and processing”.
- The choice of spindle:In the woodworking industry, spindles are generally divided into air cooling, water cooling and self-cooling. Water-cooled spindle has good cooling effect, but complicated maintenance. Clean water is usually used. If it is used for a long time, the scale will corrode the internal fittings of the spindle. The air-cooled spindle is easy to maintain and use, and the cooling effect is not as good as that of water cooling.For different materials, customers can choose different power. For example, the main shaft below K is used for carving ordinary acrylic board, and the vibration amplitude of the main shaft with low power is stable, which ensures the smooth surface of the carving material and has better effect. Eagle The engraving bathroom industry and the mold industry can use more than 1KW power, with strong cutting force and high processing efficiency.According to different models, it can also be divided into manual tool change and automatic tool change spindle. If you need to drill holes frequently in production, you can choose a machine with a row of drills.
- Transmission form:Transmission forms are mainly divided into lead screw transmission and rack transmission. Lead screw transmission is mainly used in advertising engraving machine, with high cutting precision, but low machining intensity and slow speed.Rack drive: high force and high speed, but slightly worse than lead screw drive accuracy.Rack is divided into straight teeth and helical teeth, the transmission accuracy of straight teeth is relatively poor than that of helical teeth, and the meshing degree of rack and gear is far less than that of helical teeth. Helical gear transmission is stable, with low noise and large transmission torque. Here, I suggest you choose imported brands of oblique teeth, such as Atlanta, Germany and Henrian.Guide rails: Japanese and German brands of guide rails are of high quality in the current guide rail market, such as TK self-lubricating guide rails in Japan. Other transmission forms include gear box and reducer. The gear box drive is belt drive, which reduces the speed and increases the torque at the same time, with low accuracy and needs to be adjusted regularly; The reducer has low noise and high transmission accuracy .
