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. As an experienced vertical lathe rebuilding company, we work with machines where table condition, spindle performance, crossrail alignment, and machine geometry directly affect part accuracy.
Our role is simple: keep your Bullard machines accurate, reliable, and productive for as long as possible through expert rebuilds, repairs, and modernizations. Our vertical turret lathe repair work focuses on identifying the mechanical, electrical, and geometric conditions behind accuracy problems, unreliable operation, or unexpected downtime.
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:
For a vertical lathe rebuilding company, these conditions need to be evaluated together. Wear in the table, crossrail, ram, spindle, or positioning system can affect machine geometry and show up as dimensional or finish problems at the part. Correcting these conditions is also important when the goal is to ensure machining repeatability across large or high-value workpieces.
We focus on:
The scope of vertical turret lathe repair depends on what the machine is doing and where the problem originates. Some machines need targeted mechanical or electrical repairs, while others require more extensive rebuilding to correct accumulated wear and restore dependable operation. For CNC-equipped Bullards, CNC equipment repair services in Illinois can address problems involving controls, drives, feedback systems, and other CNC-related components.
Types of Bullard Machines We Service
We work on both legacy and later-generation Bullard models, manual and CNC, including:
If your specific Bullard model isn’t listed, we are still interested in discussing it—our experience covers many custom configurations and older machines. As custom machine tool rebuilders, we evaluate the machine’s condition, current accuracy, production requirements, and existing systems before determining whether repair, rebuilding, modernization, or a combination of work is appropriate.

Keep Your Bullard Machines Earning
When a Bullard vertical turret lathe or boring mill is down or out of tolerance, schedules slip and large, high-value parts back up quickly. Timely vertical turret lathe repair can address developing mechanical, alignment, control, or drive problems before they create additional production issues. When wear is more extensive, rebuilding can provide a practical way to keep proven Bullard equipment in service.
Tell us your Bullard model, size, and the issues you are seeing, and we’ll outline targeted repair, rebuild, or retrofit options to get it back to the level of performance your operation depends on. Working with an experienced vertical lathe rebuilding company helps ensure the scope is based on the machine’s actual condition rather than replacing components that may not be contributing to the problem.
