1. High-precision

Core technology of Electro Pneumatic Drilling Units is played very well, which completely strengthened the versatility of the product and thus made the high precision of Drilling Units reflected extremely.

2. High rigidity

Axial rail structure is used, which greatly improved the overall rigidity and fully guaranteed the stability of the hole machining.

3. High performance

A unique dual sealing structure and round body that is easy and convenient to be installed are available at the end of spindle, which can meet variety of holes machining requirement.

Products can be equipped with Self Feeding Drilling Unit

1. Hydraulic Damper (PURROS® Hydro Speed Regulator)

Speed can be adjusted arbitrarily from lower to higher by a hydraulic feeding speed control device.

2. Multi-axis machining head (PURROS® Multiple Spindle Heads)

Multi-axis machining head can be amounted, which can achieve high efficiency drilling and meet different requirements of machining axes and axis spacing. Extensive multi-axis machining head sizes are available in PURROS®.

3. Desktop support (PURROS® Universal Stand)

Such desktop support is suitable for any machining directions, which can fix the Drilling Units angle freely.
