The B5020 vertical slotting machine is built for machining flat surfaces, forming surfaces, keyways and stamping dies on metal workpieces. It fits mass‑production factories, single‑piece & small‑batch workshops, repair shops and infrastructure construction‑site small‑part processing. The machine achieves grade‑3 machining accuracy. Main components include bed body, ram, rotary worktable, feed box, gearbox, electric system and lubrication unit. Its crank‑rocker mechanism converts gear rotary motion into reciprocating ram movement for slotting operations.
