 HOW TO CALCULATE THE TIME NEEDED TO GRIND A ROLL
L=length of roll
T=grinding time(seconds)
- Measure the length of roll face to be ground........MM.
- Set the spindle speed of the lathe........RPM.
- Set the feed speed of the tool carriage........MM/SEC.
- Use timer to measure the time needed for tool carriage to move 100 MM.
N=seconds
- Divide by 100 and multiply by N to get total grinding time T=L/100 x N(Total grinding time in seconds)
- Input the total grinding time T by time setting switch on the control panel.The range is 60 to 60,000 secinds.
EXAMPLE:
n=120 seconds
t=2000/100 x 120=2400 seconds
Time setting key in 2400
EXAMPLE:
o~96 SECONDS
100 MM = 96 SECONDS
1 MM = 0.96 SECONDS
GRINDING TIME 0.96 x 2500 = 2400 SECONDS
