Description

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)
