New Spindel Manufacturing

Lucas has the extensive knowledge required to manufacture new spindle bars for existing machines through our reverse engineering process, or we can work directly from your engineering drawings. We specialize in large spindle bars typically 5,6 and 7-inch in diameter.

As an upgrade to most new spindles we recommend a replaceable taper socket that can extend the life and accuracy of a new spindle for many years. We have a large amount of pre-engineered taper sockets, or we can design a custom socket with the necessary taper for your machine.

We have modified spindles in various and unusual ways to accommodate rebuilt or remanufactured machines.

 

Drawbar Rebuilding

There may be a time when your machine will require a Power Tool Ejection system rebuild. We strongly recommend that this not be attempted in-house. We regularly rebuild these systems and follow the outline below.

Spindle and PTE Mechanism

As part of the rebuild process it is very common for Lucas to suggest that we regrind the spindle taper or install a replaceable taper socket to achieve the necessary bearing contact for proper tool retention. Better tool bearing also creates more stability and accuracy while cutting.

OTT Drawbar

We have designed and manufactured many spindles engineered to accommodate OTT Jakob drawbars. We have an exclusive program for new or remanufactured spindles that not only can accommodate OTT drawbars, but also are capable of utilizing replaceable taper sockets.

Let Lucas do the complete design, manufacture and assembly of your spindle and drawbar.
