What does CNC machine shop mean?
A CNC machine shop uses Computer Numerical Control (CNC) technology to precisely manufacture custom parts from metal, plastic, and other materials. CNC machines follow programmed instructions to cut, mill, turn, and shape components with exceptional accuracy and repeatability. Criterion specializes in precision CNC machining for mission-critical industries requiring tight tolerances down to ±.0002".
How much does CNC machining cost?
CNC machining costs vary based on part complexity, material type, tolerance requirements, quantity, and finishing needs. Factors include machine time, tooling, material costs, and inspection requirements. At Criterion, we provide detailed quotes based on your specifications. Contact our estimating team for a precise quote tailored to your project requirements and production volume.
What tolerances can you achieve in CNC machining?
Criterion Precision Machining consistently achieves tolerances as tight as ±.0002" (±0.00508mm) for critical dimensions. Our Swiss turning, multi-axis CNC milling, and precision turning capabilities, combined with advanced inspection equipment including CMM and optical measurement systems, ensure dimensional accuracy for medical device, aerospace, defense, and photonics applications.
What materials can you machine?
We specialize in machining challenging materials including titanium alloys, stainless steels (300 and 400 series), aluminum alloys, PEEK and specialty plastics, and various exotic alloys. Our expertise with difficult-to-machine materials makes us ideal for medical device implants, aerospace components, defense systems, and precision optical housings.
Do you offer prototyping services?
Yes, Criterion provides production-intent prototyping using the same equipment, processes, and inspection standards as full production runs. Our prototype services allow you to test fit, function, and manufacturability before committing to high-volume production. Once approved, we transition seamlessly to production without reprogramming or requalification.
Are you ISO certified and FDA registered?
Yes, Criterion Precision Machining is ISO 13485 and ISO 9001 certified, FDA registered, and ITAR registered. We maintain a certified Quality Assurance program with multiple inspection points throughout manufacturing. Our certifications demonstrate our commitment to quality standards required for medical device, aerospace, and defense applications.
What is your typical lead time for custom parts?
Lead times vary based on part complexity, quantity, material availability, and current production schedule. We work closely with customers to accommodate project timelines and can expedite urgent orders when needed. Contact our project management team to discuss your specific timeline requirements and receive an accurate delivery estimate.
Do you provide inspection reports and certifications?
Yes, we provide comprehensive documentation including Certificates of Conformance, detailed final inspection reports, material certifications, and dimensional inspection data at no additional charge. Our quality documentation meets the stringent requirements of medical device, aerospace, and defense industries, ensuring full traceability and regulatory compliance.
