DM SERIES MULTI-SPINDLE GUNDRILLS
The DM50 and DM75 Model gundrill machines are specially designed for the North American market where accuracy, flexibility, robustness, and low cost are key customer requirements.
The multiple spindle designs, available in configurations from two to six spindles, are especially suited for high volume gundrilling applications up to Ø1.0 inch (25.4 mm).
Automation is incorporated into the machine design based on customer preference and the machine throughput required to meet customer productivity requirements.
High production, multiple machine cell configurations can be designed to meet any production requirement.

Tailstock Options
The DM Series multiple spindle machines can be equipped with a variety of tailstock configurations, depending on part type, method of load/unload, and flexibility desired.
Motor and gearbox driven counter-rotation with hydraulically actuated clamping cone part clamping is typical for most cylindrical workpiece applications.
Automation Options
- Lift & carry transport.
- Chain drive transport.
- Overhead gantry load.
- Robot load / unload.
