Lubrication

Headstock

The headstock has a pressurized lubrication system that consists of an oil pump, an oil pressure safety switch, a supply tank, oil hoses, and a manifold with oil distribution lines. The oil distribution lines direct oil to key locations, such as the spindle bearings and upper headstock gearing, to ensure that they always remain well lubricated.

The oil pump automatically starts and begins lubricating the headstock components when the master power switch is turned ON and the STOP button is reset. This ensures the headstock bearings and gears are properly lubricated before the spindle is started to protect these components against damage from a dry start-up.

Review the lubrication system diagram illustrated in Figure 97 to familiarize yourself with the function and relationship of the headstock oil system components.

Oil Pressure Safety Switch

To prevent costly damage to the headstock gears and bearings from lack of adequate lubrication, an oil pressure safety switch (see Figure 98) is installed on the output side of the pump and will shut the lathe down if oil pressure is lost for any reason.

If the headstock components are not adequately lubricated before and during operation, lathe damage could occur. Never bypass the oil pressure safety switch for any reason.
