With the DTC series spindles, tools can be clamped directly on the shank. They have a pneumatic release unit, which means that tools can be changed quickly and easily. The tool length does not have to be measured after every tool change. The DTC is ideal for the partial automation of production processes in which many different tools with the same shank diameter are used. As a result, cost-effectiveness can be increased as set-up times are reduced and no acquisition costs are incurred for tool holders.
