Selecting an Drill Unit System*
Drill-Unit systems usually include the following components:
- Drill Unit Self-Feed Drill Unit
- Spindle Attachment
- Spindle Drive
- Control Components
Determining the Requirements:
- Select the 2000 Series or 2100 Series Self-Feed Unit depending on your precision and stroke requirements.
- Choose your Spindle Attachment.
- Determine the Horsepower, Spindle Speed and Thrust recommended from the "Drill Parameter" chart. The Spindle Drive can then selected from the "Drive Selection" chart.
- Choose a Pre-Engineered Pneumatic Control System for directional stroke control and sequencing of the system.
Optional accessories, such as Position Switch Kits are available to integrate the system with other operations or PLC controls.
* The above selection criteria is provided for your information. Our Sales and Engineering staff will be happy to recommend the Drill Unit System for your project. All components are factory assembled and tested. Field connections are clearly marked. Our "Safety, Installation, Operating and Maintenance" Manual is shipped with each system.
