CONTROL

The machine has a CPU1511 for control, X, Z and C-axes

AMC operator panel with SIMATIC HMI Touch operated 9” TFT colour display

The machine can be used in manual mode, and also have a semi auto function where it is possible

put in some parameter.

There is two different way:

Manuel infeed.

There must be set 4 parameter from the screen:

a. Position z-axis right side

b. Position z-axis left side

c. The speed mm./min. the z-axis should move.

d. Number of seconds that must dwell in the ends (Example 10)

Automatic infeed:

There must be set 15 parameter from the screen:

a. Position z-axis right side

b. Position z-axis left side

c. Start diameter (example 142.512)

d. Final diameter (example 142.000)

e. Grinding rough (how much should be grind per time in diameter, example 0.060)

f. Grinding fine (how much should be grind per time in diameter, example 0.003)

g. Number of fine cut (Example 5)

h. Number spark out (Example 2)

i. Speed workpiece rough grinding

j. Speed workpiece fine grinding

k. Speed workpiece spark out

l. Z-axis speed rough grinding

m. Z-axis speed fine grinding

n. Z-axis speed spark out

o. Number of seconds that must dwell in the ends (Example 10)
