Center-work Operation (Tailstock Specification)
In general chuck work machining, the operation flow is as indicated below.
1)
Set the tailstock spindle interlock function valid.
2)
Clean the workpiece, chuck, and tailstock by supplying compressed air.
3)
Clamp a workpiece in the chuck.
4)
Check the following items:
•
Make sure that the status indicator
[CHCL]
is lit.
•
Check the workpiece to see if it is correctly clamped in the chuck.
5)
Press the
(TSINC) switch to hold the workpiece with the tailstock spindle center.
6)
Check the workpiece to see if it is correctly clamped in the chuck.
7)
Check the following items:
•
Make sure that the status indicator
[CHCL]
is lit.
•
Check the workpiece to see if it is correctly clamped in the chuck.
8)
Press the
(TSO) switch to bring the tailstock spindle into the "OUT" state.
9)
Display the PROGRAM (memory) screen and make sure that the cursor is at the head of the
program.
10)
Check the setting of the switches (mode selection switches, OVERRIDE dial, etc.).
11)
Close the front door.
12)
Press the
(START) switch to start machining of the workpiece.
13)
After the completion of the machining, make sure that the M02 or M30 command has been
executed.
Front door lock is released when the M02 or M30 command in the program is executed.
14)
Open the front door.
15)
Retract the tailstock spindle.
If the tailstock spindle is retracted, the workpiece is held only by the chuck and the
workpiece may fall.
After the completion of the machining, make sure that the workpiece is supported not to
fall from the chuck if the tailstock spindle center retracts from the workpiece.
16)
Remove the workpiece from the chuck and clean the workpiece, chuck, and tailstock by
supplying compressed air.
17)
Measure the workpiece to check if the finished dimensions are within the specified
tolerance.
18)
Machine and measure the next workpiece in the steps 2) to 17) above.
