IMPORTANT – TECHNICAL NOTES
POWER REQUIREMENTS & HEATING SPEEDS
Techniks Model 00450 operates on a 440-480 VAC, 20 amp, 3-phase power supply. Tool holders for smaller
cutting tools require less power to heat, but must be heated to a higher temperature than larger tools to
perform insertion and extraction.
NOTE: Do not activate the heat controls without a toolholder in position.
AUDIBLE FEEDBACK
During operation, ShrinkSTATION machines power source generates an audible feedback tone that
changes frequency depending on the tool holder size and temperature. It is not unusual to hear a pitch
change as the tool holder temperature increases. Do not be alarmed if you hear this tone as it is normal.
If you are heating a large tool holder, it is unlikely that you will be able to hear the tone generated at all.
SHRINKFIT TOOLHOLDERS
Techniks ShrinkSTATION machines make it easy and safe to perform shrink fit tool changes without
causing damage to the toolholder or cutting tool, as long as the machine is correctly installed and proper
operating procedures are followed. ShrinkSTATION machines are designed to work best with Techniks
shrink fit tool holders made from H13 tool steel with bore diameters from 1/8” to 1-1/4” (3mm to 32mm).
They are designed for shrink fitting tools with carbide shanks. Tool shank diameter tolerance is critical. At
least an H6 tolerance is advised for optimum performance.
Make sure toolholders are clean and free from defects before inserting the tool in the tool holder. If debris
or a burr is inserted into the tool holder with the tool, tool life may be reduced. Damage to the tool or
toolholder may also occur as the tool may be difficult or impossible to extract.
NOTE: Holders must be at room temperature before attempting to extract the cutting tool.
CUTTING TOOLS
Cutting tool shanks must be perfectly clean and free from burrs, scoring, or any damage. Any imperfections
in the shank can cause the cutting tool to lodge permanently in the toolholder. Burnished shanks can slip
in Shrink Fit holders under some conditions. Sand blasting the cutter shanks has improved the holding
power.
Techniks ShrinkFIT holders are made of H13 tool steel, tempered at 1050˚F. Heating a tool holder to or
above temper point will permanently damage the holding power of the tool holder. Never use an alternate
heat source on shrink fit toolholders or damage to the toolholder and cutting tool may occur.
