Product Description
The GMMA-60L is our most versatile mid-size plate beveler. It walks along the plate edge on its own feed motor and cold-mills the bevel with a 3 kW milling head, so a single operator can prepare V, Y and J bevels on 6–60 mm plate without flame cutting or grinding. The bevel angle is adjustable from 0° to 90°, which also lets it mill a vertical face or a J-groove radius.
Key Features
- Cold milling: no heat-affected zone, no oxide scale, weld directly after beveling
- Bevel angle adjustable 0–90°, covering V, Y, J and square-face preps
- Up to 55 mm bevel width in multiple passes, 15–20 mm per pass in Q235
- Automatic walking feed 0–1500 mm/min, stepless
- Works on the shop floor or on a support table; plates from 300 mm long
