The precision spindle for execution and alignment control of machine tools with SK - TC shank is an essential tool to ensure the correct geometry of machine tools. Primarily used as a verification device, it allows checking the alignment of the machine spindle with respect to the axes, ensuring high precision in machining operations.

 

Manufactured with high-quality materials and subjected to rigorous inspections, the test spindle features an AT2 taper accuracy, a roundness of 0.001mm, and a concentricity of 0.003mm, values that ensure high performance in the geometric control of machines. Its surface, with a roughness Ra of less than 0.4, minimizes measurement errors, while the runout with respect to the SK - TC taper of 0.003mm guarantees stability and reliability in verification operations.

 

The use of the precision spindle for execution and alignment control of machine tools with SK - TC shank is crucial during maintenance operations or after collisions between the tool holder spindle axis and other components, such as tables in milling machines or machining centers. In lathes, on the other hand, the control bar allows alignment between the turret or tool holder spindles and the rotation axis, optimizing the precision of the production process.

 

The test spindle is supplied in a vertical wooden box, ensuring protection during transport and storage. Each unit comes with a test certificate, which includes the verified dimensional values, including the concentricity measured at three points at different heights. For models equipped with a flange, the perpendicularity of the flange to the bar is also certified, ensuring perfect alignment.
