About this file
This document is an Annual Preventive Maintenance (PM) Program Task List for machinery located at Tinker Air Force Base, Building 9001, Door E69-3, in Tinker AFB, Oklahoma 73145. The document was prepared by KOMT (Kansas-Oklahoma Machine Tools, Inc.) in partnership with Makino and is dated November 11, 2025.
The PM program covers three machine models with multiple serial numbers: A81NX (SN: 1570, 1571, 1582), A71NX (SN: 599, 600, 601, 602), and U86 (SN 150). For the A81NX and A71NX models, the task lists include comprehensive annual maintenance activities across numerous subsystems including machine controller backup and accuracy checks, spindle cleaning and O-ring replacement, B-axis and ATC arm unit servicing, tool magazine and automatic pallet changer maintenance, cooling systems inspection, hydraulic and pneumatic unit servicing, chip disposal and cutting fluid supply system maintenance, splash guard and air dryer inspection, broken tool sensor and measuring unit checks, and Chipblaster equipment maintenance. The A71NX list includes additional tasks such as battery replacement for the NC backup system and absolute pulse coder/scale, and control board cooler maintenance. The U86 machine has a separate, more abbreviated task list focused on parameter and program backup, filter changes, head and component cleaning, alignment verification, clutch tension confirmation, and static accuracy verification. All task lists are designed to ensure optimal performance and extend equipment operational life.
