FEATURES
FSG-3A818.jpg

These grinders have been specially developed and improved in recent years to continuously offer you reliable high performance precision surface grinders.

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 movement, thus achieving maximum support capability for table and workpiece.

All essential castings are made of a high grade cast iron that is stress relieved by annealing, therefore ensuring the 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"(455mm) which provides more clearance for grinding.

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.

Automatic Surface Grinding Cycle

  1. Turn switch (18) to the () position. Push button (17) to feed the wheel down close to the workpiece. Then move the wheel down in increments of 0.0001" (0.002mm) with the microfeed device until a spark is generated.
  2. Total stock removal is set at the elevating handwheel.
    Maximum stock removal is 4.950"(99mm).
  3. Turn switch (13) to the () position and set the crossfeed increment on switch (10). Turn switch (18) to the () position and set the downfeed increment from 0.0001"(0.002mm) to 0.002" (0.04mm) at switch (20).
  4. Set the required sparkout times (0~9) at switch (22) and set desired wheel retract at switch (15) to have the wheel raise to the preset position after the sparkout passes have been completed.
  5. Push button (8) to start the auto-grind cycle.

Automatic Plunge Grinding Cycle

  1. Turn switch (18) to the () position. Push button (17) to feed the wheel down close to the workpiece. Then move the wheel down in increments of 0.0001" (0.002mm) with the microfeed device until a spark is generated.
  2. Total stock removal is set at the elevating handwheel.
    Maximum stock removal is 4.950"(99mm).
  3. Turn switch (13) to the (o) position. Turn switch (18) to
    the () position and set the downfeed increment from
    0.0001"(0.002mm) to 0.002"(0.04mm) at switch (20).
    Set the amount of table strokes required between each
    downfeed increment of switch (21).
  4. Set the required sparkout times (0~9) at switch (22)
    and set desired wheel retract at switch (15) to have the
    wheel raise to the preset position after the sparkout
    passes have been completed.
  5. Push button (8) to start the auto-grind cycle.
