Blanchard® Machine Tool Rebuilding & Repair

At Precision Service Machine Tool Rebuilders, large-frame machine tools have been our specialty since 1983—and Blanchard® rotary surface grinders are a core part of the installed base we support.

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

Why Blanchard Owners Work With Us

Blanchard surface grinders are built for fast stock removal and flat, repeatable surfaces on large parts. Over time, even these rugged machines experience:

Wear on columns, saddles, and rotary tables
Spindle, bearings, and drive system issues
Magnetic chuck and table flatness problems
Geometry and tram errors that show up in grind patterns
Aging, unreliable electrics and controls

We focus on:

Restoring factory-level flatness and parallelism
Improving reliability and uptime under real production loads
Extending machine life at a fraction of new replacement cost
Modernizing electrics and controls for easier support and operation

Types of Blanchard Machines We Service

We work on both legacy and modern Blanchard rotary surface grinders, manual and CNC, including:

Small to mid-size Blanchard grinders
Typical sizes in the 16″–36″ class for smaller plates and parts
Large-capacity Blanchard grinders
Machines with work tables and swings in the 42″–72″+ range
High-production Blanchard machines
Automatic-cycle and CNC-equipped models used in continuous production
Legacy and specialty Blanchards
Older mechanical, semi-automatic, and custom variants still in daily use

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