Service & Preventative Maintenance of CNC HASS Machine

24 April 2024 C.1 Background The Manufacturing Sciences & Technology Branch (MSTB) of the Army Research Laboratory (ARL) requires a preventative maintenance and service contract for three Computer Numerical Control (CNC) HASS Machines (SN: 1147998, SN: 1167245, SN: 1167195). The three CNC HASS Machines are crucial to the MSTB as they can manufacture the intricate machine parts as needed for the MTSB. The CNC HASS machines can also mill, drill, bore, tap, and perform various other work all without changing the attachment of the work piece. The machines can automatically bring several various different tools to the work location, making them versatile and crucial to the operations of the MTSB.

C.2 Objective

The Contractor shall perform the necessary work to ensure the three (3) CNC HASS Machines (SN: 1147998, SN: 1167245, SN: 1167195) are properly serviced and maintained annually under a one (1) base year and four (4) option year agreement.

C.3 Requirement
