INSTALLATION INFORMATION: Main power requirement 8 kVA; Connection to earth with flex cable min 6 AWG; Tolerance on supply voltage / frequency +/- 10% ,+/-2%; Ambient temperature of the control unit 41 deg. F 86 deg. F; Required air flow approximately 12. cubic ft / min (20m cu./ hr); Required air pressure 90 psi (6 bar) -- 150 psi (10 bar). CONTROL SYSTEM: 1. HARDWARE: GE Fanuo 16 hardware system for 4 CNC axes; 10-4' LCD color screen; Hauser operator panel. 2. DATA LMUT: / OUTPUT: One serial interface RS-232. 3. AXIS CONFIRMATION "X", "Y", "C", "U": "XY"AXIS: Continuous path control with linear and circular interpolation, tool radius compensation and feed rate calculation along the toolpath; Direct linear measuring system, resolution 0.00 0004" (0.000 1 mm). "C" AXIS: Interpolation axis for "X", "Y". This guarantees that the "U" axis is always set perpendicular to the tangent of the workpiece contour at the point of contact of the grinding wheel; Resolution of the measuring system 0.00 1 deg; Automatic switchover between planetary motion and CNC interpolation axis via M code. "U" AXIS: Programmable feed axis for the infeed to grind various diameters; Resolution of the measuring system 0.000004" (0.0001 mm.). 4. RAPID STROKE, "Z" CONTROL: Separate control system which communicates with the Fanuc via M codes; 10 different grinding levels (upper and lower reversing point and stroke speed) to be pre-set on the operator panel -- or -- unlimited number of levels programmed within the part program; Separate LED display. Target value: 0-000 1" (0.00 1 mm). 5.

MODES OF OPERATION: Machine referencing (home); Manual: axes push-buttons, electronic handwheel for all axes; Automatic: consecutive and single block; Program test with or without axes motions; Manual data input; Editing; Automatic machine switchoff when grinding unattended. MACHINE FEATURES: CNC: Dressing cycles for bore and contour grinding with compensation of the diameter reduction for dressing cylindrical grinding wheels. Graphics package, consisting of: Programming support with illustrations and parameters. Used in conjunction with the Hauser machining cycles, such as, bore grinding, contour grinding; MSS grinding wheel calibration, dressing buffer and pocket grinding; Graphic display on color screen of contours and rated bore diameter of a completcd machining program (2D)-. Rotation of the coordinate system. Rotation of the workpiece coordinate system around a center point. Smallest input unit 0.001 deg. Multiple block-skip function, with six additional skip keys on panel. MACHINE: MSS Multi-Sensoric System: 1. Function Automatic calibration of the grinding wheel; Working procedure Periodic calibration of the grinding wheel with the help of a sound sensor unit and automatic activating of a diameter compensation; Effect Allows autonomous finish grinding of bores and contours; 2. Function Automatic suppression of air grinding; Worlding procedure With the help of sound sensor units, the contact between the grinding wheel and component is monitored and allows the changeover from working speed to rapid traverse and vice versa; Effect Allows autonomous suppression of air grinding; Additional functions Acoustic and optical grinding contact indication. Ability to balance grinding wheels. EQUIPMENT CONSISTS OF: Sensoric control unit with pre-amplifier and necessary supports. Can connect up to six sensors; Unit with diamond contact plate, impact sound sensor and dressing diamond; Two impact sound sensors. CNC controlled "W" axis for automatic positioning and interpolating with "X", "Y". AC SERVO DRIVE: Machining speed 0 -- 31.49" / minute. (0 -- 800 mm / minute); Traversing speed 78.74" / minute (2,000 mm / minute); Resolution of the measuring system 0.00002" (0.0005 mm). COMPLEMENTARY FUNCTIONS: The controlled "W" axis permits the use of the G105 grinding cycle for machining bore shoulders or for expanding bores without the alternating motion, as well as any kind of feeds within the pocket grinding cycle; Tool length corrections are automatically compensated over the CNC "W" axis. Worktable adaptation for workpieces up to 3,300 lbs. (1,500 kgs). NOTE: Cost estimates are requested for budgetary purposes only.
