High-precision drilling head / multi-spindle - H.P. HEAD
Davenport Machine introduces a new dimension of accuracy and repeatability for your Model B and Davenport HP machines! 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 has stiffened 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".
The revolving head has remained consistent in it's design, however, 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".
ting time is minimal.
The New Davenport HP Head Provides:
- Increased spindle rigidity
- Improved part diameter accuracy
- Improved surface finishes
- Improved part roundness
- Less part taper and deflection
- Substantially increased spindle life
- Improved spindle index repeatability
- Improved spindle run-out
- Wear resistant coating that reduces galling and increases revolving head life
