Every spindle is purpose-built to your exact application. No off-the-shelf limitations. No unnecessary rework. Just the right fit, right away.
Direct Access to Experts
When you work with Gilman, you're not handed off to sales. You're talking directly with engineers who understand your design constraints and performance goals.
CAD and Specs Upfront
Download CAD files and spec sheets right from our configurator, or get quick access through our engineering team — helping you finalize design and integration faster.
Machine-Level Understanding
We don’t just make spindles — we understand how they fit into full machine systems. That means better integration, better support, and better long-term performance.
Unmatched Proven Experience
With over 70 years of engineering excellence behind every design, Gilman has the track record to back every claim. We’ve solved the tough problems before — and we’ll do it again.
Responsive, Reliable Lead Times
Tired of vendors ghosting you? We’re not that kind of partner. We provide clear timelines, honest updates, and fast answers — because your schedule matters.
Certified Quality You Can Stand Behind
IS09001-certified, U.S.-built, and performance tested in-house. You’ll never have to wonder whether a Gilman spindle meets spec — it already does.
Case Study: Belt‑Driven Three‑Spindle Cluster Module
An outdoor power equipment OEM needed a high‑precision machining solution for their engine casting production line. The design challenge: integrate three belt‑driven spindles into a compact, dial‑type machine station with extremely tight center‑line tolerances and uninterruptible tooling operation.
Solution by Gilman Precision:
- Designed a three‑spindle cluster using 4000C‑series belt‑driven spindles
- Two spindles at 4,620 RPM, one at 2,310 RPM, driven from the rear
- Equipped with 55 mm nose bearings, 45 mm drive bearings, ABEC‑7 angular‑contact, synthetic grease, labyrinth seals, and air‑purge provisions front and rear
- Mounted on hardened‑way Gilman slide assemblies with hydraulic cylinder actuation
- Initial spec for pitch location was .0005", but Gilman’s modules achieved exceptional accuracy within .0002"
Results:
- Met extreme bore‑location requirements without the customer’s anticipated “steering” needed
- Enabled simultaneous machining of three critical areas on engine castings in one station
- Delivered compact and benchmark performance in a tightly packed production environment
