Model FC-500D


The Models FC-200D, FC-300D, and FC-500D feature a unique video optical system with 15x–120x zoom magnification and a black and white video monitor. This system provides a higher magnification and/or a larger field of view than most machine-mounted optical comparator systems. In addition, the video camera moves with the worktable for easy set-up and for inspection during and after grinding. Their rigid construction and a 3-HP variable speed grinding spindle allow for vibration-free grinding and fast stock removal.

The Model FC-500D is a larger, more versatile machine and features vertical grinding spindle travel, a wheel travel range of 500 mm and an oscillation stroke of 70mm. The Model FC-500D is also designed for grinding reamers, drills, end mills, and multi-step form tools.

Machine Features

  • One-piece cast iron base provides extra rigidity and minimizes vibration
  • Infeed slide and grinding head slide use Schneeberger precision linear ways for accuracy and long life
  • Oscillation is adjustable in position and frequency
  • Heavy duty cross table pivots with two pairs of precision (ABEC-7) angular contact bearings
  • Cross table pivots up to 240 degrees with two adjustable positioning stops and quickly locks in any position
  • Video Optical System with 15x–120x zoom magnification range and a 12″ monitor allows for measurement and inspection of radii from 0.001″ to 0.375″ (0.025mm to 9.5mm). Moves with the worktable for easy setup and inspection
    during or after grinding.
  • The scale shown on the video monitor can be used to represent increments for various applications. The zoom optics provide magnification from 15x–120x. The magnification can be adjusted using a sample of known size, and
    locked so that the scale will accurately show the desired increments. The 1″ on the scale represents: 1/32″ (74x), 1/16″ (37x), 1/8″ (18x), 1mm (58x), 0.5mm (116x), 0.50″ (46x), 0.020″ (115x), etc.
  • Work table moves rapidly to and from the grinding position from under pneumatic control
  • Controls are placed for ease of use; the work table infeed hand wheel can be fixed in position on the RH or LH side, depending on operator preference (RH mounting is shown)

Optional Accessories

  • Brake truing device with offset bracket to mount in quick-clamping fixture. Allows truing of wheel without changing the tool setup (FC-500D only)
  • Round tool grinding attachment with 0–60 RPM variable speed drive and 24-position dividing plate. Comes with twenty-three ER40 collets to hold from 3mm (1/8″) to 26mm (1″) shank size.
  • Round tool grinding attachment with customer-specified spindle taper and fine adjustment of angle. Comes with 24-position index plate and removable tail center (FC-500D only).
  • Universal quick-clamping fixture rotates 360 degrees and inclines -20 to +20 degrees in two planes to allow for conical relief,cylindrical relief, or a combination of both. (Standard quick-clamping fixture is solid; for conical relief only.) Includes 1/2″, 5/8″,3/4″, and 1″ square workpiece holders.
