WALDRICH COBURG GM 20/10 – Year 1978
Planer Milling Machine
The machine is formed of the following main assemblies: a bed with two movable tables, a fixed bridge (two columns on each side of the beds, a cross-rail and a cross-beam) and two heads (a milling head on the right side and grinding head on the left side).
The heads displace on the cross-rail guideways. Inside of each head the ram is guided with the main spindle. The movable tables can be fixed between them with screws (as a single-table), but one of them can independently works from the other.
Three metallic telescopic covers (two fixed on external ends of the tables and one between tables) protect bed guideways.
