Hurco M-codes: reference table

Mon, 01 Jan 0001 00:00:00 +0000

On Hurco machining centers, M-codes control the machine functions: spindle, coolant, tool changes, rotary axis clamping, probing, and laser functions. The basics of tool changes and spindle commands apply here just as on any other control.

Essential M-codes

Code	Function
M00	Program stop: stops the spindle, coolant, and program execution.
M01	Optional program stop, often used when the operator needs to re-clamp the workpiece.
M02	End of program: stops spindle, coolant, and axis feed.
M03	Starts the spindle clockwise.
M04	Starts the spindle counterclockwise.
M05	Turns off the spindle.
M06	Triggers an automatic tool change.
M08	Turns on coolant system 1.
M09	Turns off coolant systems 1 and 2.
M30	End of program: marks the end of the main program.
M98	Calls a subprogram.
M99	Return from a subprogram.

Example

T1 M06 ; load tool 1
S8000 M03 ; spindle clockwise, 8000 rpm
M08 ; coolant on
G01 X50 Y20 F500
M09 ; coolant off
M05 ; spindle off
M30 ; end of program

M07	Turns on coolant system 2.
M08	Turns on coolant system 1.
M09	Turns off coolant systems 1 and 2.
M10	Turns on coolant systems 1 and 2.
M12	Clamps the C axis (rotary table).
M13	Unclamps the C axis (rotary table).
M20	Advances the indexer by one position.
M21	Starts the lubrication cycle.
M25	Retracts the Z axis to its home position (tool change position).
M26	Selects the workpiece probing signal.
M27	Selects the tool probing signal.
M29	Activates synchronous tapping.
M30	End of program: marks the end of the main program.
M32	Clamps the A axis (rotary table).
M33	Unclamps the A axis (rotary table).

M35	Unclamps the B axis (rotary table).
M36	Turns off the servo drives.
M38	Captures and sets the state of the laser “OK” signal.

M68	Activates flood coolant.
M69	Deactivates flood coolant.
M76	Normal A-axis operation (default setting).
M77	Reverses A-axis operation.
M78	Normal B-axis operation (default setting).
M79	Reverses B-axis operation.
M80	Positive C-axis rotation direction (default setting).
M81	Negative C-axis rotation direction.
M98	Calls a subprogram.
M99	Return from a subprogram.

Machine-dependent availability

Which M-codes are actually available depends on the machine model and its equipment, such as a pallet changer, rotary table, or laser measurement system. The documentation for your specific WinMax control is authoritative.
