  • Air-cooling system for precision measuring machines
    Patent number: 5027527
    Abstract: Precision measuring machine (10) has a bed (12) with a tailstock (14) and headstock (16) mounted thereon. Anvils (36, 42) are respectively mounted on the tailstock and headstock. Duct walls enclose the lower portion of the bed so that fan (62) can move air therepast. Cap shrouds (72, 82) receive air from fan shrouds (68, 84) to flood air over the tailstock and headstock. Anvil shrouds (76, 90) respectively cover anvils (36, 42) and receive air through tubes (80, 92) to also flood the anvils with air. In this way, the precision measuring machine is bathed in ambient air to reduce dimensional changes due to temperature changes.
