Since CNC lathe machining is a high-precision process characterized by concentrated operations and minimal workpiece clamping, it places stringent demands on the cutting tools used. The following outlines the key considerations for selecting these tools:
When selecting cutting tools for CNC lathe machining, the following factors should be considered:
① Tool specifications and precision: The type, specifications, and precision grade of the CNC cutting tools must meet the specific requirements of the CNC lathe machining process.
② High precision: To accommodate the high-precision nature of CNC machining and features such as automatic tool changing, the tools themselves must possess high precision.
③ High reliability: To ensure smooth machining operations without interruptions caused by unexpected tool damage or latent defects, the tools and their associated accessories must demonstrate excellent reliability and strong adaptability.
④ High durability: Whether used for roughing or finishing, CNC lathe tools must offer greater durability than those used on conventional machine tools. This minimizes the frequency of tool replacement, regrinding, and resetting, thereby enhancing machining efficiency and ensuring consistent quality.
⑤ Effective chip breaking and evacuation: Unlike conventional machining, where chips can be manually cleared in a timely manner, chips generated during CNC lathe machining can easily become entangled around the tool or workpiece. Such entanglement can damage the tool, scratch the machined surface, or even lead to accidents involving personnel and equipment, thereby compromising machining quality and safe machine operation. Therefore, tools must possess superior chip-breaking and chip-evacuation capabilities.
