Tarus DHMS

For Drilling of Tube Sheets The DHMS Multiple Spindle BTA Drilling Machine solves a big problem as a result of its clever design. TubeSheets have thousands of small diameter holes drilled very close to each other at fixed distances referred to as "pitch". Â Adding multiple spindles increases drilling productivity, but as the spindles near the edge of the TubeSheet, 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. Â In order disengage a drill to avoid conflict near the edge of the TubeSheet, the drill that is not to be used must be physically removed. Â Further, the drill bushing nosepiece must be removed. The TARUS DHMS is different... the drill feeds and bushing nosepieces are independently driven and controlled by the CNC and can be programmed to be used in any combination for any cycle. Â For example, all five spindles can run for one cycle, and the very ne xt cycle can extend any chosen nosepiece and drill / drills. To make this function even more useful, TARUS developed sophisticated Tool Life Management System 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. This machine is available with 2 to 5 spindles. Â Spindle vertical spacing (pitch) is manually adjusted as needed.
