FSG-2A818/3A818 HIGH PRECISION SURFACE GRINDER

FSG-2A8 1 FEATURES HIGH PRECISION SU FSG-2A818.3A818 These grinders have been specially developed and improved in recent years by us to continuously offer you reliable high performance precision surface grinders. And as a guarantee of that reliability we offer one full year limited warranty including parts and labor for mechanical as well as electrical components. The Double-V crossfeed guideway span has been designed applying kinematics to calibrate for minimum bending moments, thus achieving maximum support capability for table and workpiece. All essential castings are made of a high grade of cast iron that is stress relieved by annealing, therefore ensuring t he greatest stability and rigidity with low stress. An interlock has been placed between the electrical cabinet door and power supply as an added safety feature. The maximum distance from table surface to spindle centerline is 18 (450m) which provides more clearance for grinding. FSG-3A818 Note:Machine shown with optional accessories Longitudinal table movement is driven by hydraulic unit. Cross movement is driven by AC motor. Vertical feed is driven by AC motor and equipped with automatic downfeed device and manual micro downfeed device.

MACHINE CONSTRUCTION FSG-3A818(Plunge Grinder) High Precision Cartridge type Spindle Spindle is supported by 4 pieces of class 7(P4) super precision angular contact ball bearings which have been accurately measured, selected and preloaded, and then assembled in offer superior waterresistance, thus increases the life of the spindle bearings. a temperature controlled room to ensure better grinding accuracy and surface finish. The labyrinth seal type structure is designed to offer superior waterresistance, thus increases the life of the spindle bearings. 2HP Low Vibration Spindle Motor By using a 2HP class V3 low vibration spindle motor, both fine grinding and rough grinding can be performed to obtain exceptional grinding result.

FSG-2A8 3 MACHINE CONSTRUCTION HIGH PRECISION S Table Reversing Mechanism By using proximity switches, the operator can easily set a suitable table stroke for each workpiece to save grinding time and obtain higher grinding efficiency. The proximity switches have been properly covered for operator safety. Table Guideways DURABLE SLIDEWAYS MACHINE BASE SLIDEWAYS ARE INATED WITH TURCITE-B AND PRECISELY HAND CRAPED. LOW FRICTION SLIDWAYS INCORPORATED WITH AN AUTOMATIC INTERMITTENT LUBRICATION SYSTEM ENSURE HIGH ACCURACY AND LONGER WAY LIFE. The table traverses on hardened and round guideways with accurately sieved steel ball bearings, providing smooth, accurate and efficient table movement. Control Station(FSG-3A818) Elevating Micro Feed Device (FSG-3A818) The elevating system is equipped with a precision 0.0001 graduated micro feed device, consisting of a worm and wormgear for precise manual positioning of the corss axis. The control station can be easily adjusted to a comfortable position for the operator s convenience. All switches, indicators, lamps, LEDS, and displays are ergonomically designed for ease of operation.

Touch the stylus of the indicator to the table surface. Traverse the table in and out, The indicator variation shall be within 0.00008"(0.002mm). Runout of Wheel Spindle Conical Surface Apply a test indicator to the rear, middle and front points of conical surface of the wheel spindle, and rotate the wheel spindle, the variation shall be under 0.00006"(0.0015mm). Parallelism of Table Surface to Table Longitudinal Movement Attache the base of test indicator the the wheel head. Touch the stylus of the indicator to the table surface. Move the table left to right and reverse. The indicator variation shall be within 0.0001"(0.0025mm). Spindle Dynamic Balancing Test Before delivery, the spindle of each machine has to be calibrated by a portable precision dynamic vibration measuring equipment. The final amplitude of spindle vibration shall be under 0.0012"/s(0.03mm/s) Parallelism and Squareness of Wheel Spindle Centerline to Table Surface Attach the base of a test indicator to the wheel head. Touch the stylus of the indicator to the table surface. Traverse the table in and out. The indicator variation shall be within 0.00016"(0.004mm). Steel Ball Sifting Steel balls used in longitudinal movement are all heat treated and sieved by automatic machine which assures the diameter tolerance of steel balls in the same machine is under 0.00008"(0.002mm) Flatness of Ground Workpiece Due to excellent rigidity and stability of machine structure, the flatness tolerance of ground workpieces shall be 0.00012"(0.003mm) or better.
