      Most of cutters in the market is difficult to avoid the angle deviation problem of Figure 2 and Figure 3 because it is necessary to take into account inserts from different brands; However DEREK cutter is based on the DEREK own inserts, which results in the installation and matching machining as shown in Figure 1. It can achieve a near-perfect 90° design.

      Frequently Asked Questions
      Q1 What materials can the DEREK MFWN90 square face milling cutter process?
      The MFWN90 series is designed to machine a wide range of materials including 45# steel, 42CrMo alloy steel, QT500 ductile iron, stainless steel, and heat-resistant alloys. With different insert grades (JP5125, JP5225, JC1135, JC3115), it covers steel (P), stainless steel (M), cast iron (K), and heat-resistant alloy (S) applications.
      Q2 What is the advantage of DEREK inserts over other brands in achieving 90° milling accuracy?
      Most face milling cutters on the market must accommodate inserts from various brands, which inevitably causes angle deviation. DEREK cutters are designed and matched exclusively with DEREK's own inserts, allowing near-perfect 90° cutting geometry with minimal angular deviation — verified using ZOLLER precision tool presetting equipment from Germany.
      Q3 What insert grades are available for the MFWN90 series, and what are their applications?
      Four insert grades are available: JP5125 — suitable for steel and stainless steel; JP5225 — suitable for steel, stainless steel, and heat-resistant alloys; JC1135 — optimized for steel; JC3115 — optimized for cast iron. JP5125 and JP5225 feature PVD nano coating for high hardness and oxidation resistance.
      Q4 How does DEREK control surface roughness in finishing operations?
      DEREK achieves superior surface finish through precision control of insert run-out. In comparative tests on 42CrMo material using a MFWN90-50-22-4T-R cutter at Vc=200m/min and Fz=0.1mm/t, DEREK consistently delivered better surface roughness results than competitors under identical cutting conditions.
      Q5 Does the MFWN90 series support coolant-through capability?
      Yes. Most models in the MFWN90 series (up to 125-40-8T) are equipped with coolant holes (marked √ in the specification table). Larger diameter models such as 160-40-10T, 200-60-12T, and 250-60-14T do not include coolant holes. Air cooling can also be used as demonstrated in the 45# steel machining case.
      Q6 What is the recommended cutting parameter range for the MFWN90 series?
      Based on actual machining cases, recommended parameters are: Cutting speed (Vc) 140–201 m/min; Feed rate (Fz) 0.1–0.29 mm/tooth; Cutting depth (Ap) 0.3–2.5 mm; Cutting width (Ae) 30–130 mm. Exact parameters depend on workpiece material, insert grade, and machine rigidity. DEREK recommends starting with conservative parameters and optimizing based on results.
