HSF-325 OPERATION NOTICES
1. To prevent damage to the machine, toolholders, and cutting tools, please
read this User’s Guide carefully. This machine uses induction heating, and
the temperature of the toolholder being heated will rise rapidly according to
the heating time! Please confirm the characteristics of your toolholders and
cutting tools (material, external diameter, tolerances, etc.) to set accurate
heating cycles, in order to prevent damage to your toolholders, and extend
the life of the machine.
2. Stainless toolholders can easily damage the induction heating head. Stainless
toolholders may still be used in this machine; however, due to their lower
heating efficiency, they require more heat, which can cause the induction
head to overheat during repeated operation. The heating process should be
monitored closely. If the heating head gets overheated, please stop operation
temporarily until the heating head has cooled. Continuing operation while the
head is overheated will damage the induction heating head.
3. DO NOT use high-speed steel (HSS) cutting tools in induction heating
operations. Due to the similar heating characteristics between the tool and
the toolholder, it can be difficult or impossible to remove HSS cutting tools
from steel toolholders.
4. It is very important to know the diametrical size of your toolholders and
cutting tools. The machine is designed to heat toolholders to a sufficient
temperature to allow the cutting tools to shrink in/out (around 300°C). If the
temperature exceeds 350°C and the cutting tool still cannot be shrunk in/out
of the toolholder, it is likely an issue with the toolholder geometry, or the grind
tolerance of the cutting tool.
4.1. If the fit between the toolholder and cutting tool is too tight, it will be difficult
to shrink out the cutting tool. If the fit between the toolholder and cutting tool
is too loose, the tool is more likely to pull out of the holder during cutting
operations. Please choose cutting tools with the appropriate precision.

Haas Automation, Inc. | www.HaasCNC.com | 800-331-6746
4.2 Make sure to clean off any oil on the toolholder or cutting tool prior to use.
The heating procedure will carbonize any residual oil and make it more
difficult to remove the cutting tool. For cleaning off oil, we recommend
using a clean rag/cloth or solvent tank.
5. DO NOT turn on the induction heating head without a toolholder present!
To prevent damage to the machine, do not turn on and heat up the induction
head when a toolholder is not present. Prior to removing the toolholder
during the heating procedure, please press STOP to turn off the machine, to
avoid heating without an object present.
6. After a certain period of use, if you discover that the induction head is
deformed or has turned a darker color (initially, it is white), this could be
the result of the head producing too much heat (above 400°C). Reduce the
heating cycle, and service the head, as needed.
7. This machine uses a high-voltage power source. Do not dismantle and
service this machine unless properly trained. To ensure safe operation and
reduce electromagnetic interference, make sure an appropriate ground
wire is properly installed. If you are experiencing issues, contact your local
HFO for service.
8. DO NOT approach or operate this machine if you are wearing a pacemaker
or other device that can be affected by electromagnetism.

Operation Instructions
1. Before operation
• Ensure you have a proper connection to a 3-phase 220V AC power source
with proper ground wire.
• Install the correct tool sleeve and an appropriate toolholder.
• If needed, use one of the provided tool springs to set the length of the tool.
Adjust the cutting tool to the appropriate length, and ensure the toolholder
bore and the cutting tool are clean and free of oil (use a rag/cloth to remove
oil residue).
• Lower the induction heating head over the clamping portion of the toolholder.
The table below shows the recommended heights:

2. Select the operating function
At startup, the machine will remain in standby until a mode is selected. Use
the [ < > ] keys to select the Manual or Auto function, and then push the
Enter key to select the highlighted function.
3. Manual Function:
In Manu. mode, push and hold the Manual Heating Button (13) to start
heating. Heating will stop when the button is released. The red LED will turn
on during heating, and the LCD display will count the heating time until the
button is release, or after 10 seconds.
Push the Cooling key to start the air blast cooling; push the Stop button to
turn off the air blast.
! Notice: This machine has a fast heating capacity! The maximum
recommended heating temperature is 400°C. Temperatures higher than 400°C
may damage the toolholders.

4. Auto. Function:
In Auto. mode, use the [ < > ] keys to create and select between settings
for several different tools. Press the Enter key to switch between different
settings (tool diameter, heating time, cooling time, shrink in and shrink out).
Use the [ < > ] keys to adjust the values for each setting. The machine will
record and save the tool settings each time they are changed.
Push the Start key to start heating; it will stop after the set time is reached.
Once the heating cycle is complete, insert/remove the cutting tool. Push
the Cooling key to start cooling; it will stop after the set time reached. Push
the Stop switch to stop heating/cooling at any time.

• The red LED on the Manual Heating Button will turn on during the heating
period. The machine will record data every time the Manual Heating Button
is pushed.
• We recommend waiting 2 seconds after the heating period to insert the tool
into the toolholder.
! Notice: In addition to the Stop button, the Function key will turn off the heating
cycle.
! Notice: If you are not sure about the heating time, please refer to the
recommended heating and cooling times in the tables provided.
! Notice: After the heating procedure, if you are not sure whether the toolholder
and cutting tool are cooled, please use the appropriate tools and
safety equipment to remove the tools.
! Notice: This machine has a fast heating capacity! The maximum recommended
heating temperature is 400°C. Temperatures higher than 400°C may
damage the toolholders. Please contact your toolholder supplier for
detailed heating specifications.
