Webster & Bennett Machine Tool Rebuilding & Repair

At Precision Service Machine Tool Rebuilders, large-frame vertical turret lathes and vertical borers have been our specialty since 1983—and Webster & Bennett vertical boring and turning machines are exactly the kind of production-grade equipment we’re built to support.

Our role is simple: keep your Webster & Bennett machines accurate, reliable, and productive for as long as possible through expert rebuilds, repairs, and modernizations—whether you’re running classic fixed-rail vertical borers, elevating-rail machines, or CNC-upgraded Webster & Bennett vertical turning centers.

Why Webster & Bennett Owners Work With Us

Webster & Bennett machines are built for serious turning, boring, and facing of large, round components. Over time, even that level of iron sees:

Wear on tables, columns, cross-rails, rams, and saddle ways
Spindle and ram issues (noise, heat, chatter, runout)
Table bearing wear showing up as face runout or taper
Backlash in axis drives and feed systems
Cross-rail twist or sag causing out-of-flat or out-of-parallel conditions
Hydraulic and lubrication problems affecting clamping and motion
Electrical failures in motors, drives, contactors, and panels
Obsolete CNC, DRO, and drive components that are hard to support

We focus on:

Restoring or improving factory-level geometry
Improving uptime and consistency on critical production machines
Extending machine life at a fraction of new replacement cost
Modernizing drives, electrics, and controls when it makes sense
Protecting the value of proven Webster & Bennett iron already on your floor

Types of Webster & Bennett Machines We Service

We work on both legacy and modern Webster & Bennett machines, manual and CNC, including:

Single-column fixed-rail vertical boring and turning machines
Elevating-rail Webster & Bennett vertical borers
Webster & Bennett vertical turret lathes used for heavy OD/ID turning
Webster & Bennett machines that have been retrofitted with CNC controls
Webster & Bennett vertical turning centers with tool changers and auxiliary attachments

If your specific Webster & Bennett model isn’t listed, we’re still interested in discussing it.

Machine-specific PM plans for Webster & Bennett vertical borers and VTLs
Regular geometry checks and wear tracking to catch issues early
Planned repairs and phased rebuilds to spread cost over time
Guidance on when to repair, partial-rebuild, full-rebuild, or modernize
Tapered faces, out-of-flat conditions, and misaligned bores on large rings and housings
Chatter and poor surface finish on heavy OD/ID turning and facing cuts
Excessive backlash in cross and vertical axes affecting profiles and location
Spindle or ram noise, heat, or vibration from bearing, balance, or alignment issues
Table runout, wobble, or indexing errors from bearing or drive wear
Cross-rail twist or sag, showing up as out-of-parallel or stepped faces
Electrical failures in motors, drives, contactors, DROs, and legacy CNC/relay systems
Obsolete electrical and control components that are difficult or uneconomical to source

Our Webster & Bennett Rebuild Process

Evaluation & Scope

Detailed inspection, geometry checks, and (where applicable) test cuts, followed by a clear written scope and quotation.

Disassembly & Cleaning

Down to major assemblies as required; components cleaned, inspected, and tagged for repair or replacement.

Geometry & Structure

Ways restored, slides fitted, twist and sag addressed, motion components rebuilt or replaced.

Subsystem Rebuilds & Upgrades

Spindles, gearboxes, lubrication, guarding, electrics, drives, and controls rebuilt or modernized.

Reassembly & Calibration

Machine reassembled, leveled, aligned, and function-tested over full travel and speed ranges.

Run-Off & Documentation

Cutting tests where appropriate, plus accuracy data, alignment records, and updated electrical/control documentation.

Keep Your Webster & Bennett Machines Earning

When a Webster & Bennett vertical borer or VTL is down—or parts start drifting out of tolerance—it doesn’t just affect one job. It affects schedules, delivery dates, and customer confidence. Our job is to turn that risk back into a long-lived, high-performing asset.

Tell us your Webster & Bennett model, the type of work you run on it, and the issues you’re seeing. We’ll lay out repair, rebuild, or retrofit options to bring it back to the level of performance your operation depends on.
