Slotting. The different helix angles ensure that any developing vibration resonance is absorbed. The unequal helix angle promotes vibrationfree operation a swell as enables high feed rates and simultaneously reduces the undesired 'grab' effect or "corkscrew effect" during the milling process.
AlTiN coating increases surface hardness and improves tool life allowing higher metal removal rates. These unequal helix Steel cutters with corner radii are designed for higher speeds and deeper cuts. .

HAND OF CUT – Right Hand (RH): Counterclockwise rotation of the end mill is required in order to cut. Most end mills are right hand. Left Hand (LH): Clockwise rotation of mill is required to cut. HEEL – The back edge of the relieved land. HELIX ANGLE – Angle formed by a line tangent to the angle of the flute grind, and parallel to the centerline of the tool. The cutting edge angle which a helical cutting edge .
Unequal helix angle to improve high tree processing resistance to chipping. The cutting edge adopts the division angle and the spiral angle are not equal Change the feed pre blade Make the milling wave form of each edge no longer the same.
Single Variable Helix A typical variable helix end mill consists of unequal flute spacing at various points along the cutting edge of the tool. The unequal flute spacing dampens vibration that is generated by the milling process. This vibration dampening permits faster feed .
END MILLS. Slow, regular, and fast helix angles are also available. An example of a slow helix is one in which the helix angle of the cutter is about 12 degrees. A regular helix angle may be 30 degrees, and a high helix angle is 40 degrees or more. Selection of helix angle will depend on the machining task.
Unequal flute spacing helps disrupt rhythmic patterns created by the cutting edge of typical end mills, which helps suppress the development of damaging harmonics. The patented unequal helix design aids in eliminating the damaging harmonics that occur during typical machining by changing the angle at which each cutting edge enters and exits the material during the milling process.
Unequal Helix End Mill 4flt Zcc High Performance. HPC Endmills / HPC Fräser • Unique geometry design with unequal helix angle (38°/41°) in optimal combination of top grade, KMG 405. • Suitable for roughing and finishing of steel, alloy steel and stainless steel, heat resistance super alloy.
Apr 19, 2017· A unified analytical cutting force model for variable helix end mills. The cutting forces of oblique element are modeled by shearing force components due to shearing at the shear zone and edge force components due to rubbing in the tertiary zone. In the primary shear zone, a modified JohnsonCook model is introduced to account for...
Unequal Index reduces chatter. Coating increases tool life, enhances chip flow and lubricates through the cut. Standard with special edge prep to reduce breakin period allowing for higher productivity.
Jun 03, 2008· The ZCarb family of end mills features an unequal helix geometry designed to maximize stock removal and improve productivity in milling operations. The SCarb end mills are designed for machining aluminum and nonferrous materials and are said to increase material removal rates and improve surface finish.
end mill. The general rule is use less flutes for deeper cuts, with four or higher flutes for light cuts. The reason for this is the venerability of chip packing that can lead to destruction of the end mill. If the machine and program have the ability to trochoid mill, a method which is done by engaging circular arcs using an end mill smaller than the slot width (see Figure 1), a larger number of
At YIDA, we insist on maintaining the highest standards of quality control so that we can reach the greatest levels of customer satisfaction and meet the demands of our end users.
In stage one, unequal flute spacing disrupts the rhythmic pattern created by the cutting edge of common end mills. This suppresses the development of damaging harmonics. In stage two, the unequal helix design aids in eliminating the damaging harmonics by changing the angle at which each cutting edge enters and exits the material during the milling process.
