1. The core purpose and usage of comma blades
1. Deep groove processing
Due to its unique arc-shaped cutting edge design, the comma blade is particularly suitable for deep groove cutting (such as deep grooves above 3.5D). Its high tip strength can reduce cutting vibration, Ensure machining accuracy (error can be controlled within ±0.01mm), commonly used in slot machining of aviation parts and precision molds39.
Usage suggestions: Use with high-rigidity toolholders, and give priority to coated inserts (such as TiAlN coatings) to improve wear resistance.
2. Special-shaped groove and narrow slit machining
The arc-shaped cutting edge of the comma blade can flexibly cope with special-shaped grooves (such as T-slots, dovetail grooves) and narrow slit machining, especially when machining difficult-to-cut materials such as stainless steel and titanium alloys, which can effectively reduce the risk of chipping311.
Usage suggestions: Adjust cutting parameters according to the hardness of the material. For example, when machining heat-resistant alloys, it is recommended to reduce the linear speed. 20%-30% to extend the life of the blade.
3. Thread and profiling
Some comma blades can achieve trapezoidal thread turning or complex surface profiling by adjusting the clamping angle, which is suitable for oil pipelines, automobile transmission shafts and other scenes11.
Usage tips: With the macro program programming of CNC machine tools, the processing efficiency can be improved by more than 30%.
2. Key factors for selecting comma blades
1. Material and coating
Base material: Prefer cemented carbide (such as ultra-fine grain tungsten steel), taking into account wear resistance and impact resistance39.
Coating technology: PVD coating (such as AlCrN) can improve high temperature stability , suitable for high-speed cutting; CVD coating (such as diamond coating) is suitable for high-silicon aluminum alloy processing11.
2. Geometric parameter adaptation
Cutting edge arc: select the blade radius according to the groove width (such as R0.2mm is suitable for micro grooves, R1.0mm is used for wide groove roughing).
Rake angle and back angle: positive rake angle design (+6°~+10°) can reduce cutting force and is suitable for thin-walled parts processing; negative rake angle blades are used for heavy-duty cutting9.
3. Compatibility and economy
Blade interface: choose a universal tool holder (such as Screw-on interface), compatible with multi-brand tool bars, and reduce tool change costs3.
Cost-effectiveness evaluation: compare the cost of a single blade (life × cutting volume), rather than simply looking at the unit price. For example, if the life of a certain brand of blade is extended by 50%, the overall cost can be reduced by 30%
