All our knurls are made in the UK with ISO 9000 certified material suppliers using steel manufactured in the European Union. Conventional ‘bump’ knurling methods are undesirable for smaller diameter parts as the forces will deflect the workpiece. To control this problem, a straddle knurl holder should be used to provide support to the workpiece while the knurling operation is performed. Low profile straddle knurling holders are adjustable to accomodate a range of part diameters. Internal Holders are intended to be used boring bar style .
Thread forming and thread rolling are processes for forming, rather than cutting, screw threads, with the former referring to creating internal threads and the latter external threads. In both of these processes threads are formed into a blank by pressing a shaped tool, commonly called a ‘thread rolling die’ against the blank, in a process similar to knurling. These processes are used for large production runs because typical production rates are around one piece per second. Forming and rolling produce no swarf and less material is required because the blank size starts smaller than a blank required for cutting threads; there is typically a 15 to 20% material savings in the blank, by weight. Unless faced off, the end threads of a rolled fastener have a cupped end, as the surplus material in the tapering down final threads collapses uniformly over the end of the blank. Profimach provides high precision two and three dies spline and thread rolling machines.

Provide companies domestically and internationally with outstanding customer support via machinery, tooling, and industry expertise.
Users who lack thread mics rely instead on the “3-wire method”, which involves placing 3 short pieces of wire of known diameter into the valleys of the thread and then measuring from wire to wire with standard anvils. A conversion factor is then multiplied with the measured value to infer a measurement of the thread’s pitch diameter. Tables of these conversion factors were established many decades ago for all standard thread sizes, so today a user need only take the measurement and then perform the table lookup . The 3-wire method is also used when high precision is needed to inspect a specific diameter, commonly the pitch diameter, or on specialty threads such as multi-start or when the thread angle is not 60°. Ball-shaped micrometer anvils can be used in similar fashion .
These are energy efficient machines and are reckoned in the market for trouble-free functioning and durability. Our simple to use machines requires low maintenance and are offered in different specifications. Our machines are superior in functioning, durable and robust in construction. Mayes & Warwick manufactures a wide range of knurl wheels for all engineering uses, and hold a vast range of stock. The ranges covers Flat Knurls, Convex Knurls, Shell Knurls and Conical Knurls.
Dies can be supplied on a special basis for other machines and face depths, as well as from other special materials. In addition, other thread forms, left hand threads and multiple leads can be supplied; either as Duplex, single or split face dies. Precision CNC thread rolling services for steel, stainless steel, carbon steel, aluminum, brass, bronze, copper, Monel®, titanium, acetal, nylon, phenolic, PVC and PTFE.
In addition to Accu Trak, ISMS distributes dozens of high quality precision tooling lines, such as Somma Tool, CJWinter, & Albrecht Chuck. including conical, convex, concave, and attachment style dies to fit various Thread Rolling Attachments and Machines. We are committed to a 1-2 week delivery for all specials having a standard tooth form. ACCU TRAK Tool Corp. specializes in the manufacturing of standard and special knurling wheels and holders. The Fabplus philosophy is to make your next machinery purchase risk free by offering you affordable reliable machines with the industry’s best warranty on parts and labor.
A common example of die-cast threads is on cable glands (connectors/fittings). The tooling used for thread milling can be solid or indexable. For internal threads, solid cutters are generally limited to holes larger than 6 mm (0.24 in), and indexable internal thread cutting tools are limited to holes larger than 12 mm (0.47 in). The advantage is that when the insert wears out it is easily and more cost effectively replaced.
Most customers supply their machined components at a specified oversized diameter. Then we develop the correct size and grind the finished diameter as part of our preparation process. Designed for the thread rolling of standard screws, bicycle parts, automobile parts, small household electric appliances and various and various machinery parts. Our Photographer “Haffa®” made new pictures of our thread rolling machine RWT 20X CNC/AC sym with bar feeding automation for us. Accu Trak Knurling Tools are manufactured to extremely high standards from premium alloys.
knurling roll wholesalers and sellers can also find fascinating bargains upon making bulk purchases. The machine is composed by two sets of rolling rollers, PLC control system and the machine base to support the whole machine working. If knurling pistons is to be done, make sure it is done by someone with experience, and with a good working Perfect Circle Nurlizing Machine.
We are able to produce knurling tools for rolling machine or for lathe knurling tools. It is used to put knurling wheels on the notch of thermal barrier aluminum profile to improve the horizontal shearing force of the profile. Automated knurling rolling machine available are mainly modified to your particular requirement, especially electric needs, as these vary from countries. Appropriate electric conditions are vital to ensure the machine works to full capacity. These knurling rolling machine also enhance workplace hazards as the machines have an overhead protective gear to safeguard the operator.
