Davenport Machine introduces a new dimension of accuracy and repeatability for your Model B and Davenport HP machines: the HP Head.

By redesigning and improving the manufacturing process for the revolving head and the five integral spindles, Davenport introduces the new High Precision (HP) Head. Now standard on the Davenport HP, the new design stiffens the machine revolving spindles by replacing bronze or needle bearings with ABEC 9 angular contact radial bearings. This improvement now delivers spindle run-out consistently less than 0.0005″.

While the revolving head has remained consistent in its design, the manufacturing process has been upgraded to produce a more precise part. The result is a head that provides index repeatability to within 0.0006″.
