Precision Machining: Competitive Solutions for High-Volume Needs
Manufacturers seeking a world-class supply base that can deliver high-volume, precision turned parts with <10 PPM and best in region pricing rely on Greystone.
Greystone’s ability to leverage over 90 years of manufacturing experience, a skilled work force and robust quality system – including internally designed and fabricated 100% automated handling and inspection systems – means that no one is more cost-effective in North America at meeting the machining needs of industries that include automotive, industrial, defense and others.
Machining and a wide variety of secondary operations (see below) are performed in our 75,000 square foot, IATF16949 certified, Rhode Island facility housing over 90 CNC and Hydromat rotary transfer and multi-spindle machines.
Note: if you need anodizing or electroplating of hard chrome, zinc, zinc nickel, zinc phosphate, or electroless nickel, combining both Greystone machining and plating will save you money and hassles with communications between machine source and plater.
Rotary Transfer Machining
With 42 Hydromat rotary transfer machines utilizing both CNC and conventional capabilities, Greystone is one of the largest rotary transfer machining shops in the world. Rotary transfer machining capabilities include drilling, cross drilling, boring, turning, milling, external and internal recessing, threading, tapping and broaching, allowing Greystone to produce very complex components in a matter of seconds. Our machines range from 10-16 stations and can accommodate parts up to 40mm in diameter.
Multi-Spindle Machining
Greystone meets customer multi-spindle machining needs with a mix of Index, Schutte, Acme and Tornos six and eight-spindle machines. This expanding multi-spindle machining capability is both conventional and fully CNC programmable based on product requirements. Our equipment set is capable of spindle stopping and cross drilling operations allowing for completion of parts with very fast cycle times.
Secondary Operations
Further reduce your costs and turn times with Greystone secondary operations that include:
- 100% automated inspection
- Coin and leak testing
- Interior (ID) and outer diameter (OD) grinding
- Lapping
- Deburring by:
