We follow all major quality standards such as ISO 9001 and AS9100 to guarantee product quality, and ensure that we provide parts that meet all relevant customer requirements, as well as regulatory requirements.

By using the latest process controls and production best practices, we are able to ensure full transparency throughout the entire manufacturing process. To learn more about our CNC quality assurance program, you can contact us online, or get more information and details below.

Our Quality Checking Process

Our quality checking process involves a number of different steps. Some of these quality checks are standard, while others (such as materials inspection) may carry an additional cost. Contact us for more details and to determine which QC/QA steps may be necessary for your product.

Pre-manufacturing digital inspection – Before production begins on your product, CNCNOW will begin by performing a digital inspection of your CAD files and other digital assets. Our engineers and technicians will look for any potential errors or problems that may pose an issue in the production process, and work with your team to resolve these issues before production begins.
Materials inspection – We also offer materials inspection at our facility. If you are concerned about the quality of the materials that are being used for your parts or components, we can perform comprehensive assessments to ensure that your raw materials meet your engineering specifications.
Post-manufacturing IQC inspection – We will perform an IQC (internal quality control) inspection of each component as it exits our production line. Our standard six-point inspection includes a visual check, a warp check, tolerance check and more. We can customize this inspection based on your specific needs, and use batch inspections for large-scale production orders to ensure the proper balance of cost and quality.
Final inspection report – Once your order has been completed, a final inspection will be conducted of your components and parts, and issued to you along with your order. This inspection will detail any variations in quality and tolerances, and ensure that you have a full understanding of the quality of your order – giving you peace of mind.

Depending on your needs, we are happy to build a customized quality assurance program that will work for you. We have experience working in industries including aerospace and medical devices, where quality is paramount – and we use this expertise to guarantee that your machined components will meet even the most strict quality standards.

Quality Reports

We offer a variety of different quality reports for our customers. Here are some more details about each report.

Standard Inspection Report

This report is included in every single order from CNCNOW. It can be customized based on your particular needs. Our standard reports will include information such as:

Verification of critical dimensions for inspected components (such as bounding boxes, hole diameter and location, and material thickness/depth
Total part quantity and number of inspected parts
Surface finish verification
Removal of burrs and sharp edges
Threads and tolerances (if applicable)

Full Dimensional Inspection Report

For more detailed projects, our full dimensional inspection report is available. This includes all of the information in the standard report. However, it also includes a detailed assessment of the following dimensions:

Bounding box
Hole locations and diameters
Thicknesses
Depths

Actual measurements are provided for these dimensions, which are verified using multiple components. We will use calipers, gauges, and electronic Coordinate Measuring Machines to verify these dimensions.

Mill/Material Test Report

Our material test reports are available for every CNC machining project. We will verify the properties of the metal or material you are using, including aspects such as:

Material grade
Heat number
Specifications/edition year of material
Dimensions of material
Mechanical properties of the material
Chemical analysis
Heat treatment
verification (if applicable)

If you have concerns about material quality from your supplier or you are manufacturing a very high-precision part for an industry like aerospace or medical devices where no material imperfections can be tolerated, we recommend a mill/material test report to verify material integrity and grade.
