Technical Description
- Pneumatic motor for grinding tool rotation and eccentric spindle movement with infinitely speed setting
- Infinitely adjustment of eccentric spindle movement, range 0 – 3 mm
- Grinding time adjustable by timer
- Grinding disk rotation clockwise while eccentric movement counter-clockwise
- Spring loaded drive spindle for precise working pressure adjustment
- Crosshatched grinding due to individually adjustable rotation speeds thus resulting in a perfect utilization of abrasives, absolute seat flatness and reproducible grinding results
- Mirror finish valve seat surfaces
- Because of the precise machine arm positioning to the seat centre, the pre-selection of working pressure, grinding time and abrasives there are no negative or indefinite influences involved (always
- possible while doing grinding manually).
- Working range: 3/8” – 12” (10- 300 mm)
- Seat diameter: min. 10 mm (¾") max. (6") 150 mm (mounted to stand)
- Seat diameter: min. 100 mm (4") max. (12") 290 mm (with 3-jaw-chuck)
- Submerging depth: 350 mm (13 ¾")
