TARUS
DHMS Multi Spindle BTA Deep Hole Drilling Machine

The TARUS DHMS Multiple Spindle Deep Hole Drilling Machine solves a big problem as a result of clever design.

Tube sheets have thousands of small diameter holes drilled very close to each other at fixed distances referred to as 'pitch'. Adding multiple spindles increases drilling productivity, but as the spindles near the edge of the tube sheet, not all the spindles are able to drill without conflicting with the lip.

Most other multiple spindle drilling machines drive the drill feeds of all the spindles simultaneously.  In order disengage a drill to avoid conflict near the edge of the tube sheet, the drill that is not to be used must be physically removed. Furthermore, the drill bushing nose piece must be removed.

The TARUS DHMS is better. The drill feeds and bushing nose pieces are independently driven and controlled by the CNC and can be programmed to be used in any combination for any cycle.  For example, all five spindles can run for one cycle, and the very next cycle can extend any chosen nose piece and drills.

To make this function even more useful, TARUS developed sophisticated tool life management lystem to keep track of when a drill was changed and when it is due to be changed again even if the use of the spindles is not uniform and also in the event that a drill was changed out of cycle due to wear or damage.

The DHMS is available with 2 to 5 spindles.  Spindle vertical spacing (pitch) is manually adjusted as needed.
