Frequently Asked Questions (FAQ):
Q1: What types of cast iron is this insert suitable for?
A1: The CTJNR 2525M-16CEA is specifically engineered for turning grey cast iron (GCI), ductile iron (DI/NCI), and compacted graphite iron (CGI). Its grade and geometry are optimized for the abrasive nature of these materials.
Q2: What tool holder does this insert require?
A2: This insert requires a standard CTJNR style turning tool holder. The 'M' hole designation indicates the screw type used for clamping.
Q3: What are the recommended cutting parameters for this insert?
A3: Optimal parameters depend on the specific cast iron grade and operation (roughing/finishing). As a general guideline for grey cast iron, typical ranges are: Cutting Speed (Vc): 150-350 m/min, Feed Rate (fn): 0.15-0.45 mm/rev, Depth of Cut (ap): 1.0-6.0 mm. Detailed parameter charts are available upon request.
Q4: Does this insert come with a coating?
A4: Yes, it features a specialized CVD or PVD coating designed to maximize wear resistance and thermal protection when machining cast iron. Specific coating types can be customized based on application needs.
Q5: What is the significance of the '16CEA' designation?
A5: The '16' refers to the 0.8 mm nose radius (common coding: 08=0.8mm, often denoted as '16' in some systems). 'CEA' indicates the specific grade classification optimized for cast iron turning, balancing toughness and wear resistance.
Q6: Can I use this insert for interrupted cuts?
A6: While primarily designed for continuous turning, the robust carbide substrate and geometry offer good performance in light to moderate interrupted cuts common in cast iron components. For heavy interruptions, specific grades may be recommended.
Q7: Are custom grades or geometries available?
A7: Yes, Pingdu Shunfa offers customization options for substrate, coating, and edge preparation to suit unique machining challenges. Please inquire with your specific requirements.
Q8: What packaging and quantities are available?
A8: Inserts are typically supplied in standard plastic or cardboard boxes (e.g., 10 pieces per box). Bulk packaging options and larger quantities are available to meet production demands.
