Solid Carbide End Mills for Thread Milling with High Productivity / Excellent Thread Quality
Feature Advantage:
In non-rotating parts, thread milling is a good alternative to tapping and can also be used instead of thread turning.
With a thread milling cutter, the thread can be machined very close to the shoulder or the bottom of the hole.
In long chip materials, interrupted cutting in milling provides good chip control.
The same tool is used for a wide range of thread diameters and there is no upper limit for the hole size.
Full threading near the bottom of the blind hole can be machined.
It can be adjusted for specific tolerances.
Long processing range requirements and preferred solutions to avoid vibration.
Good chip control.
Good chip evacuation provides reliable performance.
Advantageous results are provided in hard material processing, as well as in poor machinability and chip shape.
The internal coolant supply facilitates threading in difficult to machine materials.
In the event of a tool break, it is easy to remove the tool without damaging the workpiece.
Thread profile deviation:
The thread shape of the thread milling cutter has a small error and can be ignored.
This depends on the relationship between the threading diameter and the cutting diameter and also on the pitch.
A good rule of thumb is that the proportional relationship between the threading diameter and the diameter of the threaded tool should be no less than 1.5.
Technical Information:
Choose the shortest tool possible.
The same thread milling cutter can also be used for larger thread sizes with the same pitch.
Machine tool requirements:
Thread milling requires a machine that can move along the X, Y, and Z axes simultaneously.
The X and Y axes determine the diameter of the thread, while the Z axis controls the pitch.
Thread milling is best done under dry machining.
A variety of different micro-lubrication systems using compressed air along with a small amount of special oil facilitates chip evacuation.
Recommended Cutting Parameters:
In internal thread milling, the tool periphery will be faster than the tool centerline.
In most milling machines, the feedrate (mm/min) is programmed based on the centerline of the spindle. This must be included in the calculation of thread milling to avoid shortening, vibration or complete fracture of the tool life.
Thread milling cutters can use the same cutting speed as conventional end mills.
For shallow cutting, the feed rate should not exceed 0.15 for a well-machined threaded surface.
