Selection Criteria For CNC Lathe Cutting Tools

CNC lathe machining is a high-precision process characterized by concentrated machining steps and minimal workpiece clamping; consequently, it places stringent demands on the cutting tools used. Dongguan Tongli Metal Products Co., Ltd. outlines the key considerations for selecting these tools below:
When selecting cutting tools for CNC lathe machining, the following factors should be considered:
① Tool type, specifications, and precision grade: These 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, CNC machining poses a risk of chips tangling around the tool or workpiece. Such tangling can damage the tool, scratch the machined surface, or even cause injury and equipment accidents, compromising both machining quality and operational safety. Therefore, tools must possess superior chip-breaking and chip-evacuation capabilities.
