Motor spindles for light milling Conceived to be used on machine tools for the watch industry components manufacturing, spindles for light milling effectively combine high rigidity and compact design.

Motor spindles with two grinding wheels for the grinding virtually zero shaft axial expansion or indexed electric spindles for turning are just some of the spindle examples manufactured on request. Power: Up to 100 kW; Moment: Up to 1200 Nm …

Details. The high rigidity and high precision of these spindles guarantees high geometrical accuracy and excellent surface finish. They are especially effective for the internal grinding of deep holes.

Even for conventional machines with belt driven spindles, TDM has developed a big variety of spindles. For high performance and for long life each spindle is balanced dynamically and equipped with special grease for reaching high speeds and spindles are rigorously tested in multiple test-runs.

With a single motor spindle many tools are available. It therefore increases significantly the number of available tools and thus the possibilities of machining. For efficient results, the new multi-tools are extremely dynamic and can reach 80’000 rpm depending on the model.
