11.4.4 Choosing tools
Dynamic balancing must be better than G=2.5 (ISO 1940 standard) at the electro-spindle's
maximum rated speed.
Always respect the following conditions when selecting a tool:
• Only use fully sharpened tools, and make sure that they are securely locked in the tool holder.
• Never use bent or damaged tools, chipped tools, or tools that are not perfectly balanced.
• Always make sure that the mating surfaces of a tool are perfectly clean and dent free before
fitting the tool in the collet and tool holder.
• Never use tools at speeds in excess of the rated speed by the manufacturer.
• Always ensure that the following essential requirements are met before using any tool at high
speed:
- The tool must be of compact, short, and lightweight design.
- The tool must be a precision instrument, and any inserts must be secured tightly.
- The tool must be balanced and must mate symmetrically with the tool holder.
- The cutting surfaces of the tool must be located near its centre of rotation.
