Sand belt grinder is a grinder that uses a rapidly moving sand belt as a grinding tool for grinding and polishing. Sand belt grinders are divided into universal sand belt grinders, external sand belt grinders, internal sand belt grinders, flat sand belt grinders, and profile sand belt grinders. Since the 1950s, sand belt grinders have developed into high-end grinding machines; Efficient precision machining equipment. The machining accuracy of sand belt grinders can generally be guaranteed within ± 5 microns, with efficiency several times higher than grinders using grinding wheels, and power consumption only a fraction of it.
Taking M4120/M4130 flat sanding belt grinder and M4212 curved sanding belt grinder as examples, the superiority of sanding belt grinder is briefly explained below.
M4120 and M4130 flat sanding belt grinders, this series of flat sanding belt grinders introduces advanced polishing technology from abroad, using high-speed, strong, water-cooled sanding belt grinding. It has the advantages of continuous, high efficiency, one-time completion of coarse and fine polishing, easy operation, environmental protection and safety. This type of machine tool is equipped with three sets of grinding heads as standard. The workpiece is subjected to rough, fine, and fine grinding processes from right to left through a conveyor belt equipped with a stepless speed regulator (worktable below the grinding head). Users can also reduce or increase the number of grinding heads (customized) according to the surface technical requirements of the workpiece and the quality of the blank surface. During polishing, high-strength magnetic force is used to hold the workpiece without the need for other fixtures, thereby improving production efficiency. The machine tool is also equipped with a demagnetization device, which automatically demagnetizes and flushes the output workpiece. If equipped with an intelligent feeding device (customized according to the characteristics of the workpiece), a fully automated production line can be achieved. The machine tool adopts a circulating cooling system, equipped with a dedicated water tank and a dust filtering and discharging device.
The M4212 curved sanding belt grinder is a dual station (dual grinding head) specialized sanding belt grinder for curved surface profiling. Pioneering domestically, filling the gap in domestic surface and side polishing and grinding technology. This machine tool uses wet strong sand belts as abrasives and implements curved surface grinding through proportional contour plates. It has various technological advantages such as advanced structure, high geometric accuracy, easy operation, strong reliability, and high production efficiency, especially suitable for large-scale side polishing and forming surface polishing and grinding of knives, scissors, measuring tools, metal stamping parts, and die-casting parts.
The M4130 sand belt grinder not only provides a delicate polishing texture, but also offers an unprecedented speed experience.
