4 Machining Services Supplier Qualification 4.1 Minimum Requirements Facilities and Equipment 4.1.1 In order to conform to this standard, the machining services supplier shall have the following on-site facilities at a minimum: — building or enclosure; — machining services; — handling and lifting equipment appropriate for the machining service; and — inspection equipment adequate for the characteristics being inspected. Activities 4.1.2 The machining services supplier’s facility shall have the on-site equipment and personnel to perform the following required activities: a) receiving verification; b) machining; c) marking; and d) final inspection. 4.2 Machining Quality Levels (MQL) General 4.2.1 Three machining services supplier quality levels—MQL 1, MQL 2 and MQL 3—are defined in this standard. Table 1 provides a reference of the requirements from this standard that a machining services supplier shall meet for the corresponding MQL. MQL 1 Machining Services Supplier 4.2.2 The base level of qualification to ensure that the machining service provided meets specific customer and industry requirements is MQL 1. A MQL 1 machining services supplier, at a minimum, shall have a self- certified quality management system. The MQL 1 machining services supplier shall determine the processes needed for the management of machining services. A MQL 1 machining services supplier shall supply the machining services defined in 3.1.8. The MQL 1 machining services supplier shall conform to the QMS elements identified in Section 5.
