TURBO-HEAD LX-1060
UVA air-driven grinding spindle Operating manual AIR SUPPLY |
|
A supply of clean, dry air of from 50 to 116 psi (3.5-8.0 kg/cm2) is required. Attachment to the shop air line is made in series with the control unit, Fig. 8A. This incorporates an air filter, pressure regulator, oil mist lubricator and oil mist air dehumidifier. Make sure the absorption cartridge of the dehumidifier is blue (active). It will turn red as it absorbs moisture. Reactivate by removing and drying thoroughly until the blue tint returns, then reinsert. - Dump any water collecting in the housing 15 by opening petcock 16. Excessively humid air may require that a second absorption unit be fitted in series with, and in advance of, the control unit.
The air and oil mist tubing of the control unit should be blown clean with compressed air each time the spindle is put into service. Take pains to check all connections for dirt, as foreign matter working into the bearings would seriously damage the spindle. LUBRICATION Turbo-Head is oil-mist lubricated. Use Gargoyle DTE Heavy Medium or a similar oil. Check the air pressure in the line between oil mist lubricator 2, Fig. 8A, and spindle. 4-10 psi (.3-.7 kg/cm2) is correct. For earlier control units, having the arrangement shown in Fig. 8B, the correct reading is 15-22 psi (1-1.5 kg/cm2). Regulate pressure by adjusting the handle of 7, Fig. 8A. If fitted, slacken locknut 20 before adjusting. Do not touch the factory-set screw 23 marked AIR. Adjust for an oil supply of 20—30 drops/min. by regulating screw 17. An abundant supply will produce a high spindle temperature. A meagre supply will produce a low spindle temperature. Adjust so as to maintain a temperature of 27° F (15° C) above shop temperature at the spindle nose. Check the oil supply daily! Never run Turbo-Head unless the oil mist lubrication is on! |
