The universal milling machine is a horizontal lifting-table milling machine whose worktable can rotate within a horizontal plane at a certain angle (usually ±45°). This key feature allows it to perform not only conventional machining of flat surfaces, grooves, and gears, but also complex machining such as helical grooves, bevels, and indexing, by adjusting the worktable or using attachments, making it extremely versatile. Through worktable rotation and the addition of a universal milling head, one machine integrates multiple functions such as horizontal milling, vertical milling, angle milling, boring, and drilling, truly achieving "one machine for multiple purposes." It is an indispensable piece of equipment for machining helical surface parts (such as helical gears, helical milling cutters, drill bit helical grooves, and worm gears). The universal milling machine for sale produced by ShanQuan uses high-rigidity materials, is durable, easy to maintain, and offers excellent economy and cost-effectiveness.
