This process uses a pusher blade to insert the work piece into coldforming area between both flat dies. Afterwards the thread is formed within one working stroke. Beside Circular dies Profiroll offers the flat thread rolling dies manufacturing as well. 70years of experience in grinding technique guarantee best resulsts.
Thread rolling is primarily a cold forming process done at room temperature, but a niche does exist for hot rolling when materials are greater than Rockwell C 45, because die life would be seriously compromised. Like centerless grinding, its sister process, the thread rolling process can be infeed or thrufeed.
We offer Flat Thread Rolling Dies which made up of premium grade raw material and advanced technology. These dies are extremely robust in nature. These products are subjected to strict tests based on various parameters to ensure delivery of fine quality and defect free products.
Popular Flat Thread Rolling Die Profiles. Single face thread rolling dies, with single setting application. Recommended for lapfree rolling, hard rolling and special thread and form rolling applications on all types of reciprocating machines Duplex doublefaced thread rolling dies, with two or fourway setting.
Thanks to our wide experience in developing our own coatings such as NIT and GG coating, specially conceived to improve wear resistance and increase the die life of our flat thread rolling tools, we are able to produce special flat dies for difficult thread rolling applications such as hard to roll parts after heat treatment 8.8, 10.9, 12.9 classes or hard to roll materials such as stainless
Threading is the process of creating a screw screw threads are produced each year than any other machine element. There are many methods of generating threads, including subtractive methods many kinds of thread cutting and grinding, as detailed below deformative or transformative methods rolling and forming molding and casting additive methods such as 3D printing or
The procedure supplants the parts malleable material with hardened steel die formed to thread size and form. Unlike the weakening effect of cutting threads that remove material, thread rolling moves molecules into the thread form, making it dense to improve quality and strength.

Thread Length vs. Roll Length o Roll work face needs to be calculated for each part to make sure proper clearances are used. o We offer this as a free service to our customers to make sure that the thread roll process and tooling life are optimized. o Rule of thumb Roll WF 2.5 x Pitch Thread Length CJWinter
Flat dies and thread rolls with 30 longer tool life. DE EN All our thread rolling dies are made by grinding process, thus meeting the highest standards in profile quality and precision, guaranteeing an excellent tool performance. We can also apply our special coatings on reground tools to increase die life
Flat thread rolling dies with sharp corners on the run out threads generates stress concentration areas which result in fatigue cracks in the thread rolled screw. With the Radius Run Out RRO offered by KADIMI, the smooth radius in the root of the thread continues right up to the point where the thread blends in the shank of the screw.

New investments in modern technologies for Eurospecial, a company located in Bulciago Italy specializing in the construction and regeneration of flat rolling dies for screws and bolts, as well as in manufacturing parts with complex profiles.. In fact, Eurospecial recently adquired two new thread grinding machines for flat rolling dies. Timely delivery and quality processing are a guarantee
Thread rolling is the preferred method for producing strong, smooth, precise, and uniform external thread forms. Thread rolling is different from other types of threading processes like cutting, grinding, and chasing. Thread rolling is a cold forging process that can be performed on any ductile metal.
THREAD GRINDINGProduce very accurate threads on hardened materialsThree basic methods are used. 1. Center type grinding with axis feed Work spins slower similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool. even multiple shaped grinding wheel can be used .
The first requirement for thread rolling flat dies is the ability to massproduce fasterners economically. We examine all dies closely using our proprietary grinding equipment, giving special consideration to heat treatment, and supply dies suitable for different purposes. For selection, please also refer to the table on page184
