Anderson Spindle Rebuild
Restoring High-Speed Stability in Anderson CNC Routers Many Anderson CNC routers are equipped with high-speed electrospindles designed for continuous-duty routing in: Over time, sustained high RPM, dust exposure, and thermal cycling can affect spindle performance. If your Anderson router is experiencing vibration, finish degradation, or rising spindle temperature, the HSD spindle assembly may require evaluation.…

Grinding Spindle Rebuild vs Replacement
A Cost & Value Comparison Guide When a grinding spindle begins to lose finish quality, develop vibration, or show thermal drift, one of the first questions is: Should we rebuild the spindle — or replace it? The answer depends on spindle condition, structural integrity, production urgency, and long-term cost strategy. This guide breaks down the…

Grinding Spindle Preload: Why Microns Matter
How Bearing Preload Affects Finish, Stability, and Thermal Performance In precision grinding applications, spindle preload is one of the most critical — and least understood — variables affecting performance. Grinding tolerances are often measured in microns. At that level, even slight changes in bearing preload can influence: Preload is not just a setting — it…

Hardinge Collet Runout Issues — Spindle or Tooling?
How to Diagnose the Real Cause of Turning Accuracy Problems Hardinge machines are known for precision collet systems and tight concentricity. So when runout increases or part accuracy drifts, the natural question is: Is the collet worn — or is the spindle developing instability? Misdiagnosing this can lead to unnecessary spindle service — or worse,…

Hardinge Grinding Spindle Running Hot
Diagnosing Thermal Instability in Precision Grinding Applications Grinding spindles operate under sustained radial load and continuous duty cycles. A small change in internal condition can cause measurable heat increase — long before catastrophic failure occurs. If your Hardinge grinding spindle: The spindle may be signaling internal instability. Heat is rarely random in a precision grinding…

Hardinge Spindle Vibration at High RPM
Diagnosing Instability in Precision Turning & Grinding Applications Hardinge machines are engineered for stability and precision. So when vibration appears — especially only at higher RPM — it is rarely random. If your Hardinge lathe or grinder: The spindle is often the primary component to evaluate. This guide explains the most common causes of high-RPM…

Why Your Hardinge Lathe Is Losing Finish Quality
A Practical Diagnostic Guide for Turning Precision Hardinge lathes are built for tight tolerances and smooth finishes. So when surface quality starts to decline — even slightly — it usually means something in the system has changed. If you’re noticing: The cause is rarely random. This guide walks through the most common reasons Hardinge turning…
