Surface finish, concentricity, and part geometry all depend on spindle integrity. Gilman’s grinding spindles are built for absolute consistency, delivering micron-level accuracy and minimal vibration under the most demanding loads. Whether you’re building a new grinding platform or upgrading an existing machine, a properly engineered spindle translates directly into smoother finishes, reduced scrap, and longer wheel life.
Grinding performance begins and ends with the spindle. Gilman ensures yours performs flawlessly from day one.

Every grinding process demands a unique combination of stiffness, speed, and temperature regulation. Gilman offers a full range of spindle configurations built to exceed the requirements of today’s high-precision applications.
For flat grinding and fine finishing operations, Gilman spindles deliver the smoothness and rigidity required for ultra-flat surfaces and consistent dimensional control.
These spindles are ideal for machine tool builders seeking reliable, repeatable results in large or small-format surface grinders.
Roundness and geometry depend on consistent spindle behavior across high rotational speeds. Gilman cylindrical grinding spindles maintain stability under radial and axial loads, ensuring high-quality part finishes across long production runs.
Demanding production lines need robust spindles that can run continuously without losing precision. Gilman’s centerless grinding spindles are built for endurance.
From aerospace components to high-end optics, unique grinding applications require unique spindle solutions. Gilman’s custom grinding spindles are engineered to integrate seamlessly into your system.
Each spindle is designed from the ground up to meet your machine’s geometry, load capacity, and finish requirements.
Grinding operations live or die by predictability. When your spindle maintains alignment and temperature stability, your process runs smoothly and parts meet spec—cycle after cycle. That’s why Gilman grinding spindles are engineered to handle heat, vibration, and wear with unmatched consistency.
Grinding precision is built on discipline—and that’s where Gilman excels.

Machine builders trust Gilman spindles because every design decision is based on data, collaboration, and performance.
Automation integrators rely on them for specialized tooling that fits into advanced robotic and multi-axis systems.
Maintenance managers and production supervisors depend on them for long service life and predictable uptime.
Gilman grinding spindles help all three succeed:
Your success is measured in uptime, finish quality, and repeatability—and that’s exactly what Gilman delivers.
Precision machine tool builders use Gilman grinding spindles to achieve industry-leading surface finishes and dimensional accuracy. Designed for repeatability, these spindles allow builders to offer customers superior part quality and longer machine life—all with predictable lead times and responsive support.
For aerospace and defense manufacturers, precision isn’t optional—it’s mission-critical. Gilman spindles are engineered for repeatable accuracy in extreme conditions, supporting grinding operations on turbine blades, housings, and high-value alloys. Every unit is backed by full documentation, traceability, and U.S.-based production integrity.
In medical machining, even a fraction of a micron can matter. Gilman grinding spindles support the ultra-fine tolerances and smooth finishes required for surgical components, implant manufacturing, and medical imaging equipment. Quiet operation, vibration control, and compliance-ready documentation simplify vendor qualification and quality audits.
Advanced automation requires grinding spindles that are compact, durable, and easily integrated into automated cells or robotic end-effectors. Gilman designs purpose-built spindles for these environments, enabling flexible manufacturing lines that maintain precision without operator oversight.
In demanding production environments—like heavy equipment or off-road components—Gilman grinding spindles deliver both toughness and accuracy. Their robust construction withstands heat, vibration, and long-duty cycles, ensuring reliability even under the most rigorous workloads.
Each industry’s challenges are unique, but the performance expectation is the same: consistent, reliable precision. Gilman delivers that standard across every spindle design.
The process begins by understanding your grinding requirements—surface finish goals, part geometry, duty cycles, and thermal constraints.
Engineers exchange CAD models and simulations to validate alignment, balance, and integration fit before production begins.
Grinding spindles are produced under controlled conditions in Grafton, Wisconsin, using precision grinding, honing, and dynamic balancing equipment.
Every spindle undergoes rigorous testing—vibration analysis, concentricity verification, and thermal mapping—to ensure compliance with design tolerances.
Your spindle arrives fully tested, documented, and ready for installation. Engineering and service teams remain available for technical support throughout the product lifecycle.
These features translate into measurable performance—fewer regrinds, longer wheel life, and smoother operation across every cycle.
To support design teams and production engineers, Gilman provides tools and documentation that simplify spindle selection, integration, and maintenance.
Every resource is designed to make specifying a grinding spindle easier—and to give engineers confidence in every decision.
Gilman’s heritage in precision manufacturing began in the 1950s with spindles built for the U.S. Navy. That same commitment to domestic quality and innovation continues today. When others shifted offshore, Gilman remained committed to U.S.-based production, protecting jobs, craftsmanship, and consistency.
Every spindle that leaves our facility reflects that heritage—precision that endures, quality that’s traceable, and performance you can rely on.
