The automatic vertical lifting right-angle grinding machine is designed for grinding welded corners on small sheet-metal box structures.
The equipment is controlled by a PLC system and driven by a servo motor, allowing the lifting stroke and speed to be freely set.
During the grinding process, the operator only needs to place the workpiece in the fixed position for grinding.
No special operating skills are required, and the operator does not need to apply physical force.
This significantly reduces labor costs and largely automates the grinding process.
It greatly improves the efficiency compared with traditional manual grinding, delivering high grinding quality and excellent consistency.

Integrated machine body with a small footprint.
User-friendly interface; grinding stroke, speed, and cycles can all be set, offering a high level of automation.
Professional grinding control system ensures stable and high-quality grinding performance.
Visual touch-screen settings with a clean and simple interface; easy operation with foot-pedal start.
High grinding accuracy, fast processing speed, and stable quality.
Easy machine maintenance.
Suitable for grinding stainless steel, carbon steel, aluminum alloy, and other metal materials.
Capable of grinding R1–R18 fillet radii.
