Gleason M&M Model 3025 Gear Measuring Machine System

The Gleason Corporation M&M Model 3025 is a CNC analytical gear inspection system designed for high-precision measurement of cylindrical gears and related components. Built on a rigid metrology platform, this system provides comprehensive evaluation of gear geometry using generating-style inspection methods.

Measurement Capabilities:
Involute profile analysis.
Lead / helix measurement.
Pitch (single, cumulative).
Runout (radial and axial).
Tooth spacing and indexing accuracy.
Composite error evaluation.
Gear and spline inspection (internal & external).
Capability for worm and similar geometries (application dependent).

Machine Configuration:
Axis Configuration: 4-Axis CNC.
X-Axis: Radial probe positioning.
Y/Z-Axis: Axial and vertical positioning.
C-Axis: Precision rotary table for indexing and rolling inspection.
Inspection Method: Generating / analytical probing.
Control: Original CNC control (non-operational).
Probe System: Mechanical/electronic probe (type dependent on configuration).

Capacity (Typical for Model 3025 Platform):
(To be verified by buyer).
Maximum Workpiece Diameter: ~25 in (635 mm).
Distance Between Centers: ~30 in (762 mm).
Maximum Module / Diametral Pitch Range: Broad range covering fine to coarse gears.
Workpiece Types: Spur, helical, spline, worm, and similar cylindrical forms.

Mechanical Construction:
Heavy-duty metrology-grade base (commonly granite or polymer composite).
Precision linear guideways and axis drives.
High-accuracy rotary C-axis for gear rolling inspection.
Enclosed inspection area with guarding (configuration dependent).
Electrical / Control.
Legacy CNC control system (non-functional).
Original drives, cabling, and interface hardware present.

Suitable candidate for:
CNC control retrofit.
Modern probing system integration.
Software upgrade to current metrology platforms.

Condition Overview:
Machine is currently non-operational.
Offered as-is, where-is.
Believed to be mechanically complete (subject to inspection).
Ideal for rebuild, retrofit, or parts recovery.

Applications:
Gear manufacturing quality control.
First article inspection (FAI).
Process validation and troubleshooting.
Tooling and cutter verification.
R&D and metrology lab environments.

Value Proposition:
Proven Gleason Corporation metrology platform.
Significantly lower acquisition cost vs. new analytical gear inspection systems.
High-value mechanical base suitable for modernization.
Opportunity to restore full analytical inspection capability at reduced capital investment.

Notes:
Specifications are based on typical configurations for this model and should be independently verified
Inspection and evaluation are recommended prior to purchase.
