6.7.7 Place hands on the left and right control wheels and move both hand wheels clockwise the
same amount to apply an even cut.
The Light Emitting Diode (LED) feed balance system tted to the Express Dual 3000 spin
grinding machine is designed to ensure that the operator has a simple visual indication that
ensures that feed of cut is applied parallel across the length on any reel.
• Set the grind stone to the reel as with any other Express Dual, adjusting the independent
handwheels until there is a light and steady contact between reel and grind stone across
the entire length of the reel.
• Press the green “reset” button to “zero” the display (zero the grinder to the reel) the central
green LED illuminates and both counters zero.
• Winding the right hand handwheel will make the amber LED to the right of display centre
illuminate (further winding would then illuminate the red led to the right of the display)
counter readout increases in value.
• Winding the left hand handwheel will extinguish red and/or amber LED’s and return to
the green LED illuminated. Both counters now read the same. Equal feed has now been
applied to both sides and the feed is balanced (PARALLEL) – no taper has been applied.
NOTE It is important that the control wheels are moved equally.
6.7.8 Apply a good hard cut. Do not be afraid of the aggressive nature of the grinding process.
