Universally applicable
The TNC 640 is particularly well suited for
milling, turning, HSC and 5-axis machining
on machines with up to 18 axes. The TNC
640 is especially attractive for the following
areas of application:
Milling/turning machines
• Simple, program-controlled switchover
between milling and turning
• Comprehensive turning cycle package
• Constant surface speed
• Tool-tip radius compensation
Universal milling machine
• Shop-fl oor programming in HEIDENHAIN
conversational format
• Fast presetting with a HEIDENHAIN
touch probe
• Electronic handwheel
High speed milling
• Fast block processing
• Short control-loop cycle time
• Motion control with smoothed jerk
• High spindle speed
• Fast data transfer
Boring mill
• Cycles for drilling, boring and spindle
alignment
• Drilling oblique holes
• Control of quills (parallel axes)
Five-axis machining with swivel head
and rotary table
• Tilting the working plane
• Cylinder surface machining
• Tool Center Point Management (TCPM)
• 3-D tool compensation
• Fast execution through short block
processing times
Machining centers and automated
machining
• Tool management
• Pallet management
• Controlled presetting
• Datum management
• Automatic workpiece measurement with
HEIDENHAIN touch probes
• Automatic tool measurement and
breakage inspection
• Connection with host computer
