Key advantages of using such a set include:
Enhanced Machining Quality: Superior accuracy leads to better surface finishes and part precision.
Extended Tool Life: Reduced runout and vibration minimize tool wear.
Increased Productivity: Reliable clamping allows for higher material removal rates and shorter production times.
The collets in these sets conform to international standards like DIN ISO 15488 (formerly DIN 6499), guaranteeing wide compatibility with ER collet chucks from various manufacturers.
Technical Highlights:
Exceptional Accuracy: These collets are manufactured to very tight tolerances. High-precision collet chucks utilizing these collets can achieve runout accuracies of around 0.00012" (3 µm) at 3 times the diameter, which is crucial for fine finishing and maintaining tight tolerances.
Large Clamping Range: ER collets are known for their generous clamping range. For example, ER collets from sizes like ER16, ER20, ER25, ER32, and ER40 typically have a compression range of 1 mm (.040"), reducing the number of collets needed to cover a given tool shank size range.
Rigidity and Stability: The design of the ER collet system, especially when used with precision chucks, provides high rigidity. This dampens vibrations, leads to a smoother machining process, protects the machine spindle, and allows for more aggressive cutting parameters.
Standardization: Adherence to ISO 15488 ensures that these precision collets can be used in a vast ecosystem of standard ER collet chucks and tool holders.
