Inspection Process

The inspection process at Custom Milling and Machining, Inc. starts when the material comes into the building. First, the material is checked for surface imperfections. Next it is checked for size and correct grade of material. The material is then cleaned, labeled and stored.  

During manufacturing, the parts being made are inspected consistently 10%-100% of the time, depending on the tolerances they require. This is done at each operation the parts undergo; parts are also visually inspected for cosmetics and deburred at each operation. When the parts are complete, 10%-50% of them are randomly inspected for a final inspection. At this time, a final inspection report is filed. Upon request, documentation can be obtained throughout the entire manufacturing process.

Calibration of inspection equipment is conducted for accuracy every one to two years, depending on the usage of the tool. This is traceable back to N.I.S.T. Any tooling that is found to be out of tolerance and not fixable, will no longer be used and will be replaced. General tooling such as calipers are clearly labeled “Reference Use Only”.

Non-Conforming Material

Custom Milling and Machining, Inc. does not accept non-conforming material. If non-conforming material is received, it is immediately sent back to the supplier. At this time, the customer is notified that the material was rejected and new material will be ordered. If this will delay shipment of the parts to be made, the customer will be promptly notified. 

Corrective Action Policy

In the event a part does not comply with a print, the part is reworked or replaced as soon as possible at no cost to the customer. At this time, an internal review is done to see why the parts were made incorrectly. Once the problem is discovered, it is fixed immediately and an internal report is filed stating the reasons for the problem.  

Packaging and Shipping Policy

At Custom Milling and Machining, Inc., parts are visually inspected for cosmetics and deviations before packaging takes place. Parts are also counted twice to assure the correct quantity of the order. They are dipped in a rust inhibiter to protect the finish before they are bagged. Parts are then put into boxes weighing no more than fifty pounds and are adequately packed to prevent damage to the parts during transportation and handling.  The final inspection report is also placed in the box before shipping.
