Z Endmill! Universal endmill

Generally, Operators have had to change tools when work material is changed. As a result, it was inevitable to stop production. Z Endmill can be used not only to carbon steel but also to stainless system materials, and from roughing to finishing, which leads to saving tool change time and increasing productivity.

Newly applied irregular flute spacing and ‘S’ shape curved edge decrease cutting loads. Special edge treatment was designed to prevent chipping problem and tool breakage.

New AℓCrN coating layer guarantees better coating lubrication and wear resistance. When machining mild steel or sticky steel materials, you can see the best surface finish and longer tool life.

Z Endmill contributes to increasing productivity and tool life up to 30% by machining various kinds of workpieces with just one tool.

Cutting condition by overhang

Notice

■ Cutting conditions of the shank taper type in case of being clamped at neck. When the overhang is increased by 1D, decrease R.P.M and feed 10%.

■ In case of the straight type adjust conditions according to the overhang. Ex) When the overhang is 3D and is increased by 1D, decrease R.P.M and feed 10%.

■ Cutting conditions are up to the machine’s condition and the shape of cutting.■ Use cutting fluid that is proper to the workpiece and produces few temperature reaction.
