High-Vacuum Containment and Control Preface Congratulations! You have purchased a precision vacuum positioning device from Nor-Cal Products. This unit is capable of many years of use with minimal care and maintenance. This manual is a tool to aid you in obtaining this service. We at Nor-Cal Products encourage your comments and suggestions on this manual. Product Description The PMXYZ series precision manipulators are a family of aluminum units which offer exceptional value per dollar.
High-Vacuum Containment and Control Installation ******** WARNING ********* Shipping vibration can loosen screws. The user must check to verify the screw fasteners have not backed off on the unit during shipment. This is critical for safe operation. ***********THIS IS IMPORTANT ************ The standard PMXYZ Manipulator can be installed directly from the packing. As usual, care should be exercised to protect the knife seal edge. The standard units mount to a 2.75" or 6" OD flange.
High-Vacuum Containment and Control PAYLOAD CONSIDERATIONS The PMXYZ Series instruments have a 20# equipment payload for vertical operation (NOT inverted). This payload is based upon the total load on the traveling flange with the base flange securely attached to the customers chamber, providing a strong and stable mounting. The payload center of gravity must be within the diameter of the traveling flange OD (Normally 2.75") and within 8" of the flange face.
High-Vacuum Containment and Control Adjustments Your PMXYZ manipulator is correctly adjusted prior to shipment. This section is included to aid the user in making changes in these settings if he so desires. LINEAR CROSS ROLLER BEARINGS: The linear bearings are adjustable on thePMXYZ manipulator. There are two sets of 3 each, 8-32 set screws that apply tension to the sets of cross rollers. To adjust, the 4 SHCSs must be loosened to allow roller bar movement.
High-Vacuum Containment and Control Lubrication All exterior bearings, micrometers, lead screws and guide rods are lubricated with GHT-2 high temperature lubricant. The user will need to add more lubricant from time to time, depending on the frequency and temperature of bakeouts and operating environment. **************WARNING************ Additional lubricant must be added to the lead screw (or Z axis micrometer threads) as the use and environment requires.
High-Vacuum Containment and Control CONVENTIONAL BAKEOUT: SUMMARY: The PMXYZ manipulator can be baked with standard UHV bakeout procedures. See safety warnings under "Lubrication". It is not necessary to remove the micrometers prior to standard bakeout. For high temperature bake-out, or repeated bake-outs of long duration, we do recommend micrometer removal. MICROMETER REMOVAL: 1.Position both X & Y micrometers at mid travel. Lower the Z micrometer to it's minimum. 2.
