High Productivity Carbide Milling Inserts For Thread Milling , Tungsten Carbide Inserts

Carbide Milling Inserts 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.
