Air hydraulic drilling unit
Air hydraulic drilling unit BE 33
The basic design of the BE 33 consists of a vane motor powered compressed air, a pneumatic cylinder, and a closed hydraulic system. The total stroke length can be variably subdevided into rapid advance and working feed over the whole range. The throttle / check valve in the hydraulic system permits exact setting of feed rate and high speed return.
Features
• Very compact design
• Built-in hydraulics for controlled working feed
• Adjustment of drilling depth with positive stop guarantees a high degree of accuracy
• Extra stable spindle bearing
• Low noise level
• Minimal air consumption
