3.2 Operation Cautions and Warnings

Operation Notices

There are safety risks for operators. Follow the safety instructions and operating specifications to avoid the following hazards:

  •     Electric Shock
  •     Burns
  •     Damage to Equipment, Tools, and Tool Holders

Safety Instructions

  • The shrink fit machine uses a 3-phase 208/240V power supply. For details, please refer to “1.2: Specifications”. Before the equipment is powered on, the voltage and current capacity of the power cord must satisfy the specifications on the electrical parameter table.
  • The power cord must be firmly connected and grounded. A ground failure will create the risk of electric shock to the operator.
  • The external power supply must be connected to the air switch.
  • To prevent electric shock hazards from lightning, disconnect the power supply during thunderstorms.
  • When the equipment is cleaned, maintained, repaired, or not used for a long time, the unit must be unplugged.

Warning: There may still be residual voltage (current) after the device is powered off. Wait five minutes before working on any internal components.

  • All electrodes are potentially dangerous. Do not touch the live parts. Operators must ensure that their clothes and body are dry and must not work in a humid environment. 
  • Wear protective shoes when operating the machine.
  • In the process of hot loading and unloading the cutting tool, the operator must wear protective gloves to avoid being burned.  

Any metal object close to the induction range of the heating head will be quickly heated to a high temperature. Therefore, it is not safe to wear metal jewelry such as rings, necklaces, and bracelets while the machine is being used.

  • People with pacemakers and other metal objects in their bodies must stay away from the shrink fit machine.
  • Do not use the machine with damaged or removed safety devices.

Qualified Operator

The HSF-450 should not be operated without proper training. Only trained professionals and technicians may operate the HSF-450. It is the operator's responsibility to prevent the equipment from causing harm to other personnel and objects.

Working Environment

This HSF-450 needs a well-ventilated area for proper heat dissipation during use. Do not block the air inlet and outlet of the device. 

1. Avoid placing the HSF-450 in areas with.

  • Sunlight, near heat sources, and large temperature changes.
  • High humidity.
  • Excessive dust.
  • Unstable/Uneven foundation

2. Environmental Requirements

  • Environment temperature: 23°F~40°F (-5℃~40℃).
  • Relative humidity: ≤85%.
  • Installation space: 2 meters x 1.5 meters.

3. Pressure source requirements

  • Air pressure 75 to 87 PSI (0.5 to 0.6 MPA).
  • Dew point temperature: lower than 1°F (-17℃).
  • Requires clean air, no moisture or oil mist.

4. Cooling water requirements

  • Machine coolant mixed to manufacturer's specifications.

5. Power system requirements:

  • The power supply and electrical cable must support 3-phase 208/240V 15A 50/60Hz. More information can be found at “1.2: Specifications”.
  • Do not turn on the power to the HSF-450 before the electrical cable is connected.
  • The power supply must be turned off when the equipment is not used for a long time.

Tool Safety

Wear heat resistant gloves when handling the tool holder or cutting tools to avoid accidental burns.

 Caution：

  • Tools must have an H7 grind or lower. Tools with H8 grind and higher may come out of their tool holders while machining. 
  • Unevenness, scratches, bumps, and improper laser labels on cutting tools will affect the heat expansion process.
  • Do not use any flammable or explosive cleaning products during the heating process.
  • Clean the bore of the tool holder before loading to avoid residual chips and cutting fluid on the tool shank. The residual oily substance of the tool holder may be burned during the heating process.

Tips & Tricks: When a shrink fit tool holder won’t be used for a long time, spray the tool holder with an anti-rust oil.

Shrink Fit Tool Safety

  • Do not start the heating process without a tool holder loaded and the heating head properly in place.
  • When the heating is over, immediately start the cooling process. This prevents heat radiation from the tool and tool holder from  damaging the heating head. 
  • If the cutting tool is not installed or removed within the set time, let the tool holder cool down completely before trying again. Immediate reheating is not recommended. Continuous heating may cause damage to the tool holder and heating head.
  • If the cutting tool still cannot be installed or removed, it may be caused by the following reasons:
  1. Incorrect setting parameters of shrink fit machine
  2. Improper tool shank diameter
  3. Damaged tool shank
  4. Carbon deposit in clamping hole

The heating time cannot exceed 20 seconds, heating for a long time will cause the heating head to overheat. When the heating head overheats, the machine will shut down until the machine cools.
