What is high precision CNC machining?
High precision CNC machining is computer-controlled milling, turning, or related machining performed to very tight dimensional tolerances. It is used when component fit, function, surface features, and repeatability are critical. Cir-Q-Tek uses multi-axis and multi-tasking equipment, CAD/CAM programming, and high-end metrology inspection to produce complex parts with tolerances as close as ±0.0005 inches.
What materials can be CNC machined?
CNC machining can be used with standard metals, high-strength and high-temperature alloys, engineered plastics, ceramics, composites, and other non-metal materials. Cir-Q-Tek also finish machines aluminum, zinc, magnesium, iron, and stainless steel castings. Material selection should reflect the part’s strength, weight, heat, corrosion, electrical, and application-specific requirements.
What information is needed for a CNC machining quote?
For non-PCB and non-PCBA machined items, Cir-Q-Tek requires CAD and 3D data and/or fabrication drawings to prepare a quote. Complete files should identify dimensions, tolerances, material, finish, quantity, revision level, and any critical inspection requirements. Providing this information early helps confirm manufacturability, select efficient machining methods, and reduce delays during quoting and production.
How tight can CNC machining tolerances be?
Achievable tolerances depend on the material, part geometry, feature size, machining process, and inspection requirements. Cir-Q-Tek’s CNC capabilities can maintain tolerances as close as ±0.0005 inches for appropriate applications. Not every feature needs the tightest tolerance, so identifying function-critical dimensions on the drawing can improve manufacturability and help control production cost.
Can you machine prototypes and production quantities?
Yes. Cir-Q-Tek supports parts in virtually any quantity, from prototype and pre-production components through recurring production orders. The team can help address machining and manufacturing challenges during the design stage, then scale the approved part into repeatable production. Parts stocking and just-in-time shipping are also available to help customers manage scheduled releases and inventory needs.
What CNC processes do you offer?
Cir-Q-Tek offers CNC milling and turning using high-performance, multi-axis, and multi-tasking machinery. Capabilities include live tooling and multiple spindles, which can combine operations and produce finished parts from a single setup where appropriate. These resources support complex geometries, intricate features, cylindrical forms, threads, and precision finish machining for cast components.
How is the quality of machined parts verified?
Machined parts are inspected using high-end metrology equipment under strict supervision in ISO 9001, ISO 13485, and IATF 16949 certified facilities. Inspection planning should focus on the dimensions and features that affect assembly, safety, or performance. Cir-Q-Tek’s certified processes provide added assurance for customers serving medical, automotive, industrial, and other demanding markets.
Can Cir-Q-Tek help improve a part design before machining?
Yes. Cir-Q-Tek provides engineering support to assist with part design and resolve machining or manufacturing challenges. Reviewing a design before production can identify difficult-to-machine features, unnecessary tight tolerances, material concerns, or opportunities to reduce setups. CAD design and CAM programming expertise help translate functional requirements into efficient, repeatable manufacturing strategies.
