How Can You Reduce Tooth Wear in a High-Speed Precision-Machined Straight Cylindrical Gear
High-speed power transmission places immense stress on gear teeth. Among all gear types, the Precision-Machined Straight Cylindrical Gear is particularly vulnerable to tooth wear when operating at elevated velocities. Wear manifests as abrasive scoring, pitting, or even plastic deformation—each reducing efficiency and risking catastrophic failure. For engineers and maintenance teams, the question is not if wear will occur, but how to systematically minimise it.

What Is the Correct Way to Lubricate and Clean a Thread Plug Gauge (LG) Without Damaging It
Precision measurement tools are the backbone of quality control in manufacturing, and among them, the Thread Plug Gauge (LG) holds a critical position. Used to verify internal thread dimensions, this instrument demands meticulous care. Improper cleaning or lubrication is one of the fastest ways to alter its certified dimensions, leading to false passes or rejects. At NERES, we have spent decades studying gauge wear patterns, and we consistently find that correct maintenance extends the service life of a Thread Plug Gauge (LG) by up to 300% while preserving its calibration integrity. This guide outlines the only professionally accepted methods for cleaning and lubricating these gauges without compromising their geometry.
