Quality Assurance

TDB Machining is committed to delivering products of the highest quality to our customers. We proudly uphold an ISO 9001:2015 certified quality management system.

CNC Machining Built on the Cornerstone of High-Quality

At TDB, CNC machining quality control is the cornerstone we’ve always built on. Every individual involved with our CNC machining is held to the highest standards of quality and integrity... It’s in our DNA! As a leading machine shop, the focus of our quality management system is to meet or exceed customer specifications on all machining products and services, to be in a state of continual improvement, and to provide the highest level of customer satisfaction.

We are proud of our quality system certifications; however, quality is more than the accreditation. It’s how TDB approaches every step of our process – from initial discovery to final shipment. When you work with TDB, you’ll experience the meticulous attention to detail we deploy in reviewing your specifications, prints, models, and documentation requirements before your work ever reaches the production floor of our CNC machining facilities. Our investment early in the process helps ensure positive returns in the end.

Quality Control Processes

A strict and thorough internal quality control system is established and maintained in place to ensure critical information gets where it’s needed before it’s needed.

  1. Inspection on raw materials: Checking the quality and quantity of the raw materials delivered to the manufacturing facility.  Any discrepancies or defects must be reported and resolved before the raw materials are accepted for use in the production process.
  2. Acceptance of raw materials: Verifying that the raw materials meet the required quality standards and are suitable for use in the production process.  This step is critical, as it ensures that the final product will meet the required quality standards and that any issues with the raw materials are identified and resolved before production begins.
  3. Inspection on production process: Monitoring the production process to ensure that it is being carried out according to the required standards and specifications.  Any deviations or issues must be identified and resolved as soon as possible to prevent any impact on the final product's quality.
  4. Acceptance of the product: Checking the final product to ensure that it meets the required quality standards and specifications.  This is the final step in the quality control process, and it is critical to ensure that the product is of the required quality and that any issues are identified and resolved before the product is shipped to customers.
