1. The selection of models should be based on the shape of the work, material, cutting characteristics, diameter and material of tools, rotation speed (cutting speed), etc.
2. The drilling capacity displayed in the above table is based on values representing a drilling depth of two times the diameter of the drill.
3. The standard attachment for the hydro speed regulator is RB-3140. Please specify an optional Hydro Speed Regulator if required. (Optional Hydro Speed Regulator Models: RB-3160, RB-31100, R-3180A, R-31130A)
4. Maximum weight of the attachment that can be mounted when machining downwards is 50 kg.
5. Make sure to use a collet chuck or spindle nose when the hardness of carbide drills and tool shanks is higher than that of general HSS (high-speed steel) drills.
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®.
