Features of PB130 DRO Planer Type Boring and Milling Machine
1. The spindle box is installed on the column and moves vertically along the column guideways; column is fixed on the slide and moves transversely along bed guideways; rotary table is installed on the slide and moves longitudinally along bed guideways.
2. Headstock is clamped by disk spring and released hydraulically; slide is clamped and released hydraulically.
3. Bed, column, headstock and other main parts adopt resin sand molding high-strength castings.
