Frequently Asked Questions
Q1 What materials can the SN45 series face mill be used to process?
The SN45 series face mill is designed for a wide range of workpiece materials, including steel (P), stainless steel (M), cast iron (K), super alloys (S), and hardened materials (H). The SNMX1205ANN-M insert with JP5225 grade is especially suited for 45# steel and similar carbon steels.
Q2 What insert is compatible with the SN45 series face mill?
The SN45 series is compatible with DEREK's SNMX1205ANN-M insert. The recommended grade for general steel machining is JP5225. These inserts are available in stock and rated as Excellent for steel and stainless steel applications.
Q3 What are the recommended cutting parameters for the SN45 face mill on 45# steel?
Based on the machining case, the recommended cutting parameters for 45# steel (HB180) using the SN45-125-40-10T-R are: Cutting speed (Vc) 200m/min at 500r/min, Feed per tooth (Fz) 0.2mm/t (Vf=1000mm/min), Cutting depth (Ap) 2mm, Cutting width (Ae) 50mm, with water coolant.
Q4 What sizes are available in the SN45 face mill series?
The SN45 series is available in a comprehensive range of diameters from 50mm to 200mm, including: 50mm (4T/6T), 63mm (6T/8T), 80mm (7T/10T), 100mm (8T/12T), 125mm (10T/16T), 160mm (12T/20T), and 200mm (14T/24T). Both right-hand (R) and left-hand (L) versions are available for most sizes.
Q5 Do the SN45 face mills support coolant-through capability?
Yes, most SN45 series models support coolant-through (marked with ✓ in the specifications). Models with diameters up to 125mm (D50–D125) include coolant holes as standard. Larger models (D160 and D200) do not include coolant holes but can still use external coolant supply.
Q6 How do I select the correct SN45 face mill for my application?
To select the correct SN45 face mill, consider the following: (1) Machine spindle bore and arbor diameter (d), (2) Required cutting diameter (D) based on workpiece width, (3) Number of teeth (T) — more teeth allow higher feed rates, (4) Workpiece material — refer to the insert grade compatibility chart, and (5) Whether coolant-through is required.
