Machining Case
Testing Equipment: Tool Presetting and Measuring Machine from ZOLLER, Germany
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.

FAQ
Frequently Asked Questions
Q
What materials can the DEREK MFWN Square Face Milling Cutter process?
The DEREK MFWN Square Face Milling Cutter is designed to process a wide range of materials including 45# steel (HB180), 42CrMo alloy steel, QT500 ductile iron, stainless steel, and heat-resistant alloys, depending on the insert grade selected (JP5125, JP5225, JC1135, or JC3115).
Q
Why does DEREK achieve a near-perfect 90° design compared to other brands?
Unlike most cutters on the market that must accommodate inserts from multiple brands — resulting in angle deviation — DEREK cutters are designed specifically around DEREK's own inserts. This dedicated matching ensures installation precision that achieves a near-perfect 90° cutting angle, as verified using ZOLLER tool presetting and measuring equipment from Germany.
Q
What insert grades are compatible with the MFWN90 cutter series?
The MFWN90 series is compatible with WNGU080608N-GM inserts in the following grades: JP5125 (Steel & Stainless Steel), JP5225 (Steel, Stainless Steel & Heat-resistant Alloy), JC1135 (Steel), and JC3115 (Cast Iron). SECO inserts are also compatible.
Q
What are the recommended cutting parameters for finishing 42CrMo mechanical parts?
For finishing 42CrMo mechanical parts, the recommended parameters are: Face milling cutter MFWN90-50-22-4T-R (Φ50), cutting speed Vc = 201m/min, feed rate Fz = 0.29mm/t, cutting depth Ap = 0.3mm, and cutting width Ae = 30.0mm. The PVD nano coating on DEREK inserts ensures stable wear resistance throughout the operation.
Q
How does DEREK control axial runout to improve surface roughness?
DEREK employs precision manufacturing and strict quality control of insert seating geometry to minimize axial runout after insert installation. As demonstrated in comparative testing with the MFWN90-80-27-5T-R (Φ80, 5 teeth) cutter, DEREK's precision runout control delivers significantly better surface roughness results under identical cutting conditions compared to competing products.
Q
Does the MFWN90 cutter series support coolant-through capability?
Yes, most models in the MFWN90 series support coolant-through (marked with √ in the specifications table), including sizes from Φ50 up to Φ125. Larger models such as the Φ160, Φ200, and Φ250 variants do not include coolant holes (marked with -). Air cooling can also be used effectively, as demonstrated in the 45# steel machining case.
