Haas Lathe Classic Control Panel Overview 256

"Haas Lathe Classic Control Panel Overview" describes the Classic Haas Control (CHC) lathe panel from Haas Automation®, Inc. The class identifies the different areas of the control keypad and describes the function of each individual key. The Classic Haas Control (CHC) lathe control panel has three distinct regions. Manual controls of the Haas lathe, such as the HANDLE, EMERGENCY STOP, and FEED HOLD key, function much like the manual controls of other machines. The display screen shows all relevant information needed during the machining process. The control keypad allows the operator to enter a variety of machine commands. After taking this class, users will have a comprehensive understanding of the control panel's different functions and be able to successfully perform basic operations , including powering up and powering down, checking and activating coolant, sending the turret to machine zero, activating the chip conveyor, and leaving messages.
