Frequently Asked Questions
What is the difference between the DEREK HN45 and SN45 45° Face Mill?
The HN45 uses HNMX0907ANSN-R inserts and is available in diameters from 50 mm to 315 mm, making it suitable for heavy-duty cast iron and steel machining. The SN45 uses SNMX1205ANN-M inserts with a thicker edge (6 mm) and is optimized for steel and stainless steel applications, available in diameters from 50 mm to 200 mm. Both feature a 45° approach angle for low vibration cutting.
What materials can DEREK 45° Face Mills machine?
DEREK HN45 and SN45 face mills are designed to machine a wide range of materials including P (steel), M (stainless steel), K (cast iron), and other common engineering materials. The specific insert grade selection (e.g., ZP5125, ZP5225, JP5225) determines the optimal material compatibility for each application.
What is the maximum cutting depth achievable with the SN45 face mill?
The SN45 face mill features a thick insert design with an edge thickness of 6 mm and a minimum thickness of 4.5 mm, which ensures a maximum cutting depth (Ap) of up to 8 mm. This robust design also provides excellent resistance to insert breakage during interrupted or heavy cuts.
Do DEREK HN45 and SN45 face mills support coolant-through capability?
Yes. Smaller diameter models (50 mm to 125 mm for HN45, and 50 mm to 125 mm for SN45) are equipped with coolant holes (marked √ in the specification table). Larger diameter models (160 mm and above) do not include built-in coolant holes, as indicated by "-" in the specification table.
Which insert grades are recommended for machining cast iron with the HN45 face mill?
For cast iron machining with the HN45 face mill, the ZP5125 insert grade (composition: HNMX0907ANSN-R) is recommended and is available in stock. This grade is rated as Excellent (▲) for P Steel and K Cast Iron applications, making it ideal for materials like HT300 with hardness up to HB200.
Can DEREK 45° Face Mills be used on both vertical and horizontal machining centers?
Yes. DEREK HN45 and SN45 face mills are compatible with standard vertical machining centers, as demonstrated in the machining case examples. The dynamic slant design and low vibration characteristics also make them suitable for use on horizontal machining centers. Always refer to the recommended cutting parameters (Vc, Fz, Ap, Ae) for optimal performance on your specific machine.
