Marposs offers TBD, the Tool Breakage Detector, a time-saving laser-based solution for broken tool detection on machine. TBD on milling machines and machining centres permits to keep under control the process, thanks to a very short tool checking cycle.

Fast and reliable detection achievable by the TBD allows to reduce production time and to avoid expensive work-pieces scrap due to wrong cutting process by damaged or broken tools. All functionality is contained within the TBD unit compact housing, which can be mounted outside the machine area, saving space on the table.

It is possible to choose among different working modes, which endow TBD with a great flexibility. Switching the power to the maximum gives TBD the chance to recognise a tool placed at a longer distance (up to 2 m), with a standard capability to check the breakage. If a smaller tolerance is required, the reduced power can be set obtaining a smaller beam. Furthermore, a user can choose the filtering level of the signal. In fact, during the checking cycle, some coolant drops could interrupt the beam or coolant stuck on the tool could create variation in the signal received. Setting ‘Hi Filter’ makes the software of the TBD more restrictive in order to give the more reliable response. On the other hand, choosing ‘Low Filter’ TBD responds in a faster way, as the filter is less severe.

Lastly, it is possible to choose the appropriate range of spindle speed, up to 5000 rpm.

Also, Marposs SpA has recently introduced the new TBD HS, High Speed, on its wide range of products for tool checking on milling machines and machining centres. The new TBD HS is a programmable system for non contact checking hi-speed tools, particularly committed to those applications where there is the need for hi-speed spindles, up to 80,000 rpm.
