derekType–MFWN Square Face Milling Cutter

Kr=90°

Standard diameter: 50-250mm

More options for inserts

Feature:

■6 cutting edges achieve better machining economy.

■Insert has wide-area applications which is suitable for machining cast iron, steel, stainless steel and difficult-to-machine materials.

■Excellent matching of cutter body and insert is close to perfect 90 degree vertical.

■A variety of machining areas is feasible including surface, step, groove and vertical milling.

■The design of large front angle and dynamic slope provides low resistance and vibration during machining. The roughness of workpiece surface is also improved.

Machining Case

Vertical machine

Processed material: 45# steel

Material hardness: HB180

Speciafication of mill:

MFWN90-160-40-10T-R

Insert: WNGU080608N-GM JP5125

Cutting rate(Vc): 140m/min (280r/min)

Feed(Fz): 0.15mm/t (Vf=420mm/min)

Cutting depth(Ap): 2.5mm

Cutting width(Ae): 130mm

Coolant: Air

Contrast Experiment：Angle Deviation

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.

Contrast Experiment：Surface Roughness

Insert：WNGU080608N-GM JP5225

Cutting speed(Vc)：200m/min

Feed rate(Fz)：0.1mm/t

Cutting depth(Ap)：1.2mm

Cutting width(Ae)：40mm

■ Better roughness result received under the same cutting conditions due to DEREK precision control of run-out.
