Giddings & Lewis

Giddings & Lewis® Machine Tool Rebuilding & Repair

At Precision Service Machine Tool Rebuilders, large-frame machine tools have been our specialty since 1983—and Giddings & Lewis® has always been a major part of the installed base we support.

Our role is simple: keep your G&L equipment accurate, reliable, and productive for as long as possible through expert rebuilds, repairs, and modernizations.

Why Giddings & Lewis Owners Work With Us

Giddings & Lewis machines are built for heavy cuts and tight tolerances on large, critical components. Over time, even these rugged platforms experience:

Wear on ways, ballscrews, and tables
Spindle, ram, and headstock issues
Geometry and indexing errors
Obsolete, unreliable CNC controls and drives

We focus on:

Restoring factory-level accuracy
Improving reliability and uptime
Extending machine life at a fraction of new cost
Modernizing controls and automation

Types of Giddings & Lewis Machines We Service

We work on both legacy and modern G&L models, manual and CNC, including:

Horizontal Boring Mills (HBM)
T-bed horizontal boring mills (including RT and PT series)
Table-type and floor-type horizontal boring, drilling, and milling machines
Vertical Turning Centers / Vertical Lathes (VTL/VTC)
V Series vertical turning centers and lathes
Large VTC-style vertical turning centers
Machining Centers & CNC Mills
G&L machining centers and CNC horizontal mills for large, complex parts

If your specific G&L model isn’t listed, we are still interested in discussing it—our experience covers many custom and older machines.
