CNC Machining Rock Hill SC | Milling, Turning, Inspection | Farris Group
Rock Hill operations need machined components that fit, seal, and align the first time. We provide CNC machining services in Rock Hill, SC for carbon steel, stainless, and aluminum components used in housings, bearing blocks, plates, shafts, and precision brackets. Our machining floor operates under ISO 9001:2015 certification, with routed travelers, tool life controls, and inspection plans that keep parts conforming.
We review models and drawings for GD&T, datum strategies, tolerance stacks, and thread specifications. Material is verified by grade and heat lot. We document setups and inspection plans so repeat runs track to the same outcome.
Where Tolerance Meets Throughput
We run 3- and 4-axis CNC milling for prismatic parts. Strategies include high-efficiency roughing and finish passes that protect surface finish. We maintain flatness and perpendicularity using stable workholding and verified probing cycles. CNC turning covers shafts and bushings with concentricity targets. Live-tool features and milled flats are completed in the same setup where possible to reduce stack-up.
Threads follow UNC, UNF, and metric standards. We drill, tap, and ream to size on dedicated cycles. Bores are finished with boring heads to achieve true position. Typical capability holds ±0.001 in on standard production, with tighter windows when the print calls for it and the process supports it. Surface finishes can target Ra 32 to Ra 16 on critical faces.
Deburring is controlled with manual and mechanical methods. Edges are broken to a specified radius. Stainless parts can be passivated (ASTM A967) on request. Aluminum parts can be routed to anodize or coating when required. Identification can be engraved or marked for traceability.
Inspection includes in-process checks with calibrated gauges and final verification with CMM or height stand routines for critical features. We record dimensions for key characteristics and supply reports when requested. Tooling and gauges are calibrated and logged.
Packaging protects edges and finishes. Kits can be grouped by assembly or machine center. Labels match your part numbers and revision levels.
Ready For Audits, Ready For Work
Many Rock Hill customers support public programs. We are a FedLinks Verified Federal Vendor, so we deliver material certifications, inspection reports, and process documentation that align with procurement. Records are organized for quick review.
