Automatic Operation¶
WARNING
Start automatic operation after ensuring that the dry-run function is released and each override switch setting (spindle, rapid traverse, cutting traverse) is appropriate. [Unexpected speed of spindle and each axis]
The length of the bar stock must be shorter than the spindle length unless a bar feeder is used. Do not insert bar stock into the spindle while the spindle is rotating. [Spindle runout increase/Collision with bar/Bar bending]
Some switches have covers preventing unintentional switch actuation. Keep covers closed except when pressing the switches. If a switch cover is damaged, contact the DynamiTech Service Department. [Switch actuated unintentionally/Unexpected machine operation]
Before opening the operator door during a machining operation, make sure that the door interlock function is activated. Close the operator door before restarting the machine operation. [Serious injuries]
When changing the machine lock function from valid to invalid, ensure change is performed after executing a cycle. [Gap generated between program command and machine position]
Confirm the cycle start indicator is extinguished and the program end indicator is illuminated before exchanging the workpieces. [Program not completed, causing machine to start operating]
Before carrying out unmanned operation over extended periods, or machining using an inflammable coolant workpiece, install automatic fire extinguishing equipment. [Fire]
CAUTION
Before mass production, check the program and perform a test cutting in single block mode. [Workpiece and cutting tool collision]
When machining bar stock on a machine equipped with a bar feeder or spindle through-hole, use straight bar stock only. When machining bar stock with a diameter smaller than that of the spindle (or draw bar), use a guide bush. [Machine vibration/Impaired machine accuracy]
Keep the chip conveyor operating all the times during automatic operation. [Chip accumulation causing chip conveyor damage]
If abnormal noise or vibration is generated during machine operation, determine the cause and take appropriate action. [Machine damage/Impaired machining accuracy]
When releasing the hard overtravel on a machine with that function, the axis movement interlock can be released by pressing the [2nd O.T. Release] button. Do not move the axis in the direction in which the hard overtravel occurred. For safety reasons, feed the axes using the handle feed ×1 until the hard overtravel status has been canceled.
