Frequently Asked Questions
FAQ Reference
Q What is the adjustment accuracy of the CBA25 boring head?
The adjustment dial features a vernier design where one small graduation/grid on the dial corresponds to a diameter adjustment of exactly 0.01 mm, enabling high-precision finishing operations.
Q What base material is used to manufacture these boring heads?
These new type micro finish boring heads are constructed using premium 3Cr13 stainless steel, offering outstanding wear resistance, toughness, and long-term dimensional stability under rigorous machining conditions.
Q How does the step-back adjustment method prevent backlash errors?
To eliminate mechanical play, you first adjust the dial clockwise to a diameter slightly smaller than your target measurement, and then dial it back counterclockwise to the final targeted scale division before locking the fastening screw.
Q Is it necessary to purchase a separate insert seat for the CBA25?
Yes, different boring ranges (e.g., 25-33mm, 32-40mm, or 39-47mm) require corresponding matching insert seats. Please check the range specifications or consult with us to determine the exact insert seat for your requirements.
Q Are the boring heads compatible with blades from other manufacturers?
Yes. The modular design of these boring heads allows them to work seamlessly with designated blades of identical standard specifications across various brands, eliminating the need for customized tool grinding.
Q What is the standard packaging and lead time for shipments?
Standard orders are packed securely in carton boxes. We usually dispatch ready stock within 15 days, while standard bulk production or custom configuration orders take around 30 days.
