A roll type tap that does not expel chips.Features· The TAFLET series uses workpiece plastic fluidity to raise screw threads and create female threads.· It does not produce chips and provides stable screw accuracy.· The fiber flow of the material is not interrupted and therefore the strength of the female threads is strong.Applications· Ideal for rolled threading of non-ferrous metals such as aluminum.

Material Requirements: A known disadvantage of thread rolling is its incompatibility with hard materials. The materials to be rolled must have a hardness not greater than HRC 40. Materials that can be rolled are low-carbon steels, mild steels, stainless steels, copper alloys, and often, aluminum. Moreover, the material must have the right degree of ductility. The recommended range is 12 to 20% elongation factor.

Threadforming tap

In the in-feed process, the profile grooves of the rolls have the pitch of the thread to be produced. The rolls, driven at the same speed, move in the same direction. During rolling, the workpiece moves due to friction with no axial shifting. As the thread produced by this means is an exact copy of the rolling dies, threads of this kind have a very high pitch accuracy. The maximum length of the thread is limited by the width of the dies (30-200 mm).

Highly accurate female thread machining is performed without producing chips, due to plastic distortion of aluminum and aluminum alloys.

Thread Rolling Speeds: Thread rolling speeds depend on the mechanical and power limitations of the machine, the thread diameter, and the material and hardness of the metal stock. Rolling speeds can range from 30 to 100 m/min. Low rolling speeds are required for hard materials while high speeds are for soft and ductile materials.

UKO carbide circle thread rolling dies are made of the highest quality materials. Manufactured to exacting standards, we can offer standard and customized thread rolling dies for in-feed and through-feed applications. Thread forms are precision ground and dies are produced to fit most types of circular screw nail thread rolling machine.

A rise up type tap that does not expel chips.Features· The TAFLET series uses workpiece plastic fluidity to raise screw threads and create female threads.· It does not produce chips.· Less inconsistent screw precision.· The fiber flow of the material is not interrupted and therefore the strength of the female threads is strong.Applications· Suitable for roll threaded screw machining of mild steel and stainless steel with hardness of 20 HRC or less.

Thread rolling is an integral cold-forming process, used to produce a variety of threads, knurls and helical gears. The process involves deforming a metal blank by rolling it through a die. This process forms external threads along the surface of the metal blank. Internal threads can be formed using the same principle. In contrast to other widely applied threading operations such as thread cutting, thread rolling is not a subtractive process. That means it doesn’t remove metal from the stock. Rolled threaded fasteners offer advantages such as stronger threads, precise final dimensions, good surface finish, and a lower coefficient of friction.

Steel and non-ferrous alloys are equally suitable. Capable of high-speed cutting, features greatly improved durability, and provides high-efficiency tapping.

In-feed rolling uses a timed machine cycle. This is used for the general rolling of parts up to the maximum width of the face of the dies, less die chamfers. In-feed rolling dies, also known as plunge rolling, are suitable for threading with a shoulder or a headed workpiece.

Coolant and Lubricant: Coolants or cutting fluids are extensively used in thread cutting, but these are also necessary for thread rolling. Deforming the metal also generates heat which can compromise both the dies and stock. Moreover, coolants can act also as lubricants to reduce the friction between the dies and stock.

Circular thread rolling die gives more control to the rolling process, with power to all rolls and controlled penetration rates. This allows harder and more difficult materials to be threaded.

Chamfer Angle: Chamfer is the tapered conical surface at the start of a thread. Before rolling, the edge at one end of the stock must be machined to have a chamfer. A correct chamfer angle must be set to properly shape the thread at the end. The recommended chamfer angle is 30° for most cases.

Suitable for increasing the life of the tap or as a countermeasure against chipping, while cutting aluminum (cast, rolled and forged) and other light alloys.

Thru-feed rolling is used for rolling threads that exceed the maximum face width of the dies, as well as for continuous rolling of long threaded bars. Here, the rolling dies have grooves with no pitch; the groove cross-section is that of the standard flank profile. The thread pitch is produced by skewing the die axes by the pitch angle of the thread. This means the workpiece is given an axial thrust and moves one pitch length in the axial direction for every full revolution. As the axial thrust kicks in immediately when the workpiece enters the assembly, larger threads are not formed to full depth in one pass.

Feeding: There are three basic techniques for feeding the stock into the dies: radial in-feed, tangential feed, and through feed. In radial in-feed, the dies move radially towards the axis of the stock. For tangential feed, the pitch of the stock approaches the rollers from its side making square, tangential contact. Lastly, through feed involves a cylindrical die that mates against the stock causing it to move axially.

It is a roll tap that's capable of tapping without lubrication for burred thin iron plates and steel with relatively short processing length at the size of M6 or less.
