THE POWER OF TECHNOLOGY AND PRECISION

Milwaukee Gear Company employs the highest quality performance standards at each step in the design assistance, manufacturing, and testing processes.

Quality Standards

Every Milwaukee Gear employee is responsible for maintaining the customer's quality requirements. Design engineering is based on AGMA standards. During gear manufacturing, staff constantly monitors and checks quality on the latest equipment available. Manufacturing inspections are measured and stored electronically with documentation available. ISO 9001:2008 certified


Quality Assurance Program

Milwaukee Gear has earned ISO 9001:2008 certification by adhering to a comprehensive quality assurance program, which includes the following elements:

Purchased Product Controls

A supplier rating system monitors performance and provides data to assist suppliers in assessing their improvement efforts.

Process Control

Computerized operation routings, quality control plans and set-up sheets are generated for each production lot. Preventative maintenance activities help maintain or improve up-time and process capability on manufacturing equipment.

Inspection and Testing

Defect prevention methods data generated by operators and inspectors is recorded and reviewed at final audit inspection. Detailed instructions are listed on the corresponding Quality Control Plans.

Control of Measuring and Test Equipment

All gauge calibration equipment is traceable to the National Institute of Standards and Technology (NIST). Our Gauge Master program categorizes, manages and tracks all gauges for calibration and recall. The Crib Master program allocates and automatically tracks all gauging used in the production process. This software also is utilized for its gauge repeatability and reproducibility features.

Statistical Techniques

Statistical software is used throughout the manufacturing process to perform Machine and Process Capability Studies along with in-process monitoring of critical quality characteristics. Historical data is constantly used to assess the effectiveness of machine and process improvements.

Continuous Improvement

To maintain the highest levels of customer satisfaction, Milwaukee Gear uses the elements listed above as well as other methods to realize continuous improvement throughout our operation.

Quality Gear Geometry Laboratory

Our state-of-the-art Gear Inspection Laboratory features the Klingenberg and M&M, CNC controlled, four-axis gear inspection centers. These instruments incorporate the most advanced coordinate measurement technology in the world and can automatically supply extremely accurate verification of gear tooth topography.

Our Inspection Laboratory is equipped to measure and chart lead, involute profile, size, pitch variation, run-out and total composite value. We have a large selection of master gears available for inspecting tooth composite errors. Our laboratory provides an isolated environment with temperature and humidity controls to ensure the integrity of all test results.
 
Nital Etch and MPI Inspection
Milwaukee Gear's laboratory offers nital etch inspection per ANSI/AGMA 2007-B92. Nital etching is a non-destructive, in-process inspection method that detects surface tempering and/or rehardening in all gear grinding processes. We also can provide Magnetic Particle Inspection (MPI) to detect cracking.
Inspection Systems
Our Gauge Block capabilities include Master Grade, certified and traceable to the National Institute of Standards and Technology (NIST), dedicated for calibration only. Other equipment includes a digital optical comparator plus instrumentation required for surface finish and Rockwell hardness inspection.

Quality Gear Geometry Laboratory

As a final check of both quality and performance Milwaukee Gear tests gear drives on our in-house test plate in our assembly area.

All readings are documented on test sheets and saved as part of the quality control records.

Units are spin tested and checked for...
  • Fastener tightening torques
  • Horsepower draw/efficiency factor
  • Gear noise and sound level
  • Lubrication leaks
  • Bearing and lubricant stabilization temperatures
