Fire Prevention

WARNING

Failure to observe the following warnings may result in a fire or machine damage. DynamiTech is not liable for any fire whose cause is other than a product defect.

When machining using coolant

  • Receive the MSDS (MATERIAL SAFETY DATA SHEET) from the coolant manufacturer directly yourself as the customer and use coolant without any chemical effects on the machine. Take careful note of the effects on the human body and the storage method described in the MSDS.

  • Before starting automatic operation, check the amount of coolant in the coolant tank, and replenish coolant if necessary. When insufficient coolant is applied to the cutting point, the machined part will heat up due to insufficient cooling, and this may result in a fire.

  • Do not use a flammable coolant such as oil-based coolant, as it has high risk of a fire which may spread to the entire machine. If a flammable coolant is used out of necessity, any consequent fire or accident must be dealt with as the users' responsibility.

  • Always monitor the machining process and do not carry out unmanned operation. Install appropriate automatic fire extinguishing equipment to quickly extinguish fire at an early stage.

  • Check the flash point and the ignition point of the coolant to be used. Manage the material of the tools and workpieces, and tool wear so that the temperature during machining does not exceed these points.

  • When coolant becomes a mist inside the machine, it may burn explosively in abnormal temperature conditions. Change the coolant discharge method so that no coolant mist becomes suspended inside the machine, or install equipment to collect the coolant mist generated.

  • Use an explosion-proof mist collector.

  • Check the instructions on coolant in the manuals in advance, and follow them.

When machining without using coolant (including dry cutting and semi-dry cutting)

  • Check and manage the materials of the tools and workpieces to be used to prevent fire due to heat generated in the machining process.

When machining workpieces made of flammable material

  • Always monitor the machining process and do not carry out unmanned operation. Install appropriate automatic fire extinguishing equipment to quickly extinguish fire at an early stage.

  • Check and manage the tools and machining conditions to be used so that the temperature during machining does not exceed the ignition point.

  • Materials such as magnesium may burn explosively when exposed to water while burning. Check the fire-fighting methods and equipment in advance, and install the equipment at suitable locations for quickly extinguishing fire.

Before starting automatic operation

  • Reconfirm that all parts of the tools and tool holders are securely tightened. Insufficient tightening leads to insufficient tool clamping, and may result in an accident or a fire caused by heat.

  • Reconfirm that the workpiece is securely clamped. If a workpiece is not clamped securely, it may shift and make contact with a tool, resulting in a fire caused by heat.

  • Do not use worn or damaged tools. If worn or damaged tools are used, chips may clog them, resulting in a fire caused by heat.

  • Before starting automatic operation, reconfirm that the tools and programs to be used are correct. Failure to use the correct tools and programs may result in an accident or a fire. Especially with a program in which the same pattern is executed repeatedly, confirm that the tool is selected correctly before starting the second set of repetitions after the first machining.

  • Create a program after confirming the machining conditions so that the heat generated by rubbing is minimal. Creating programs without this consideration may result in a fire or machine damage.

  • The conversational programming function creates NC programs based on general machining conditions, but the final responsibility for determining the machining conditions rests with the user. DynamiTech is not liable for the machining outcome of the conversational programming function.

  • During and after machining, completely remove chips if necessary. Failure to remove chips completely may result in a fire, depending on the workpiece material and machining conditions.
