FAQs
What is precision CNC machining and how is it different from conventional machining?
Advanced precision machining, specifically precision CNC machining, uses computer-controlled tools to cut parts to extremely tight and repeatable tolerances, producing complex geometries with a level of accuracy and consistency that conventional machining cannot achieve. While traditional machining relies heavily on manual operation and operator skill, advanced precision machining integrates CAD/CAM programming, automation, and often GD&T standards to ensure each feature is manufactured exactly to specification. This results in highly accurate, uniform parts across large production runs, making advanced precision machining the preferred choice for industries where reliability and precision are critical.
What is “contract manufacturing” and how does it relate to EMS (Electronics Manufacturing Services)?
You outsource some or all production to a partner who builds to your specs. EMS is a subset focused on electronics design/assembly/testing for OEMs. Lets you scale, cut costs, and focus on R&D/core competencies.
Which industries commonly use precision machining services?
Aerospace, defense, medical, semiconductor, energy, communications, industrial, health tech. High-spec sectors rely on certified, traceable processes.
What information do you need from me to provide a quote?
When requesting custom machining services, the accuracy of your quote depends on the completeness of the information you provide. Typically, this includes 3D CAD files in STEP or IGES format, a detailed 2D drawing with all tolerances and surface finish requirements, the desired quantities, material specifications, and target deadlines. If your project requires special processes such as heat treatment, coating, or specific inspection protocols, these should be clearly noted. Complete and accurate information allows custom machining services providers to deliver faster, more precise quotes and avoid delays in production planning.
How fast can I get a quote back?
For CNC precision machining services, quote turnaround times vary based on job complexity and the quality of the information provided. Simple parts with clear CAD files and drawings are often quoted quickly, while complex assemblies or incomplete submissions may require additional time for review. If your project is time-sensitive, communicate this urgency upfront, and many CNC precision machining services providers can prioritize urgent jobs, but incomplete or unclear details can extend the process.
What factors affect lead time for machined parts?
In precision machine and manufacturing operations, lead times for machined parts are influenced by several factors, including material availability, part complexity, required finishing steps, and the current workload of the shop. Components requiring multiple operations, tight tolerances, or intricate features will take longer to program and produce. Outsourced processes like heat treating or specialized coatings can add days or weeks to the schedule. Early discussions about these variables can help you plan accurately and align production timelines with delivery needs.
Do you offer prototyping and low-volume runs?
Separate prototyping cells avoid disrupting high-volume lines. Our business is based in ‘High mix, low-volume” production where prototyping is pretty standard
What certifications should I look for in a shop (and why)?
When working with a provider of engineering consulting services, certifications are a reliable indicator of a shop’s capabilities and quality systems. ISO 9001 certification demonstrates a strong quality management framework, while AS9100 ensures aerospace-level controls and full process traceability. For medical device components, ISO 13485 certifies compliance with rigorous manufacturing and quality standards. Choosing a shop with the right engineering consulting services certifications ensures your parts will be produced consistently, meet industry requirements, and maintain full documentation for regulatory compliance.
How do you ensure quality, what inspection tools do you use?
In precision component manufacturing, quality is ensured through advanced inspection technology and strict quality control procedures. This often includes coordinate measuring machines (CMMs), portable probing systems, and documented QC plans, all supported by inspection equipment traceable to NIST standards. Serialized inspection reports provide traceability for each part, and first article inspections or certification samples can be provided to verify compliance before production. These steps ensure that precision component manufacturing delivers parts that meet or exceed all specified requirements.
Will you sign an NDA and protect my intellectual property?
Reputable providers of engineering consulting services take intellectual property protection seriously and will readily sign a non-disclosure agreement before beginning work. Established shops have secure data management systems to protect your CAD files, specifications, and project documentation from unauthorized access. It’s important to define ownership of tooling, design files, and any proprietary code in the contract, ensuring you retain full rights upon project completion. This safeguards your intellectual property while building trust and transparency in the engineering consulting services relationship.
