Bullard

Bullard Machine Tool Rebuilding & Repair

At Precision Service Machine Tool Rebuilders, large-frame machine tools have been our specialty since 1983—and Bullard® vertical turret lathes and vertical boring mills have always been a core part of the equipment we support.

Our role is simple: keep your Bullard machines accurate, reliable, and productive for as long as possible through expert rebuilds, repairs, and modernizations.

Why Bullard Owners Work With Us

Bullard machines were built to take heavy cuts on large, critical components. Over time, even these rugged vertical turret lathes and boring mills experience:

Wear on columns, crossrails, rams, and tables
Spindle and gearbox issues
Geometry, alignment, and indexing errors
Aging electrics, controls, and drive systems

We focus on:

Restoring or improving original accuracy
Improving reliability and uptime
Extending machine life at a fraction of new replacement cost
Modernizing controls and support systems while preserving the iron

Types of Bullard Machines We Service

We work on both legacy and later-generation Bullard models, manual and CNC, including:

Vertical Turret Lathes (VTL)
Vertical Boring Mills (VBM)
Bullard “Spiral Drive” and “New Era” vertical turret lathes
Bullard Cutmaster series
Bullard Man-Au-Trol and Dynatrol machines
Bullard Dynatape and other CNC-equipped Bullards
Standard and high-column Bullard configurations for large swing and tall workpieces

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