Our grinding operations utilize precision equipment specifically selected for accuracy, repeatability, and versatility across diverse component requirements. We maintain multiple grinding platforms including surface grinders, cylindrical grinding capabilities, and specialized jig grinding equipment for complex geometries and precision tooling applications.

Primary grinding equipment includes multiple Harig surface grinders featuring both manual and automatic operation modes, complemented by an Okamoto automatic wet surface grinder for production efficiency and consistent surface finish quality. Our Chevalier universal cylindrical grinder provides both internal and external grinding capabilities with 5" x 12" capacity for precision shaft and bore finishing operations.

Specialized grinding capabilities feature a Moore No. 3 jig bore for ultra-precision boring and grinding operations requiring exceptional accuracy and surface finish quality.

Key grinding and finishing services include:

• Surface grinding with automatic and manual capabilities for flat surface finishing
• Cylindrical grinding for both external and internal diameter precision finishing
• Precision honing operations using dedicated Sunnen equipment for bore finishing
• Complete deburring and finishing services for all machined components

Surface Quality and Precision Standards

We specialize in achieving surface finishes and dimensional tolerances that meet the most demanding specifications across aerospace, defense, and precision industrial sectors. Our grinding processes consistently deliver surface finishes measured in micro-inches, supported by comprehensive quality control protocols and precision measurement capabilities.

All grinding operations are performed in our temperature-controlled facility, ensuring dimensional stability throughout the process and eliminating thermal variations that could affect final component accuracy. We utilize precision measurement instruments including micrometers, bore gages, and coordinate measuring equipment to verify dimensional requirements and surface finish specifications.

Quality achievements in grinding operations include:

• Surface finish capabilities measured to demanding micro-inch specifications
• Dimensional tolerances achievable to ±0.0001" on critical ground surfaces
• Flatness and parallelism control for precision reference surfaces and critical interfaces
• Cylindricity and concentricity control for shaft and bore grinding applications
• Complete documentation and certification for aerospace and defense components

Material Expertise and Application Experience

Our grinding capabilities accommodate the full spectrum of materials commonly specified in precision manufacturing, from standard tool steels and stainless alloys to exotic aerospace materials requiring specialized grinding techniques and parameters. We maintain grinding wheel inventories and parameter databases optimized for each material type and application requirement.

We have developed extensive experience in grinding operations for defense and aerospace components, where surface integrity, dimensional stability, and performance characteristics are critical to component function. Our applications include precision surfaces for optical systems, sealing surfaces for hydraulic and pneumatic components, and reference surfaces for measurement and assembly fixtures.

Integration with Manufacturing Processes

Our grinding and finishing services integrate seamlessly with our CNC machining operations, providing complete component finishing under one roof. This integrated approach eliminates additional handling, reduces lead times, and ensures consistent quality control throughout the entire manufacturing process from initial machining through final finishing operations.

We coordinate grinding operations with upstream machining processes to optimize overall manufacturing efficiency and component quality. This includes strategic material removal planning, finish allowance optimization, and processing sequence development to achieve both dimensional requirements and superior surface quality in the most cost-effective manner.

Whether your components require precision surface grinding for sealing applications, cylindrical grinding for bearing surfaces, or specialized jig grinding for complex geometries, Nortek Inc. combines advanced grinding capabilities with proven expertise to deliver finishing services that meet your exact specifications. Our commitment to surface quality, dimensional accuracy, and customer satisfaction makes us the preferred choice for demanding grinding applications.

We understand that grinding and finishing operations often represent the final manufacturing steps that determine component performance and assembly success. Our attention to detail, quality focus, and comprehensive finishing capabilities ensure your components meet both specification requirements and application performance expectations.
