LMT Fette rolling heads create exterior profiles of any type. Cold forming enables high accuracy in just seconds. As a user, thread rolling provides you with several advantages in comparison with machining: Production time is extremely short, while high thread strength and consistent dimensions are achieved. You also benefit from excellent surface quality and long tool life. All of those advantages combined set the bar for chipless forming.
Top quality rolled threads and knurls guarantee you excellent component reliability and durability. You can roll endless threads or short threads in front of or behind a collar. Nearly all materials with a minimum stretch of approx. 5% can be rolled. With a thread rolling head, you can even roll thin-walled pipes with the help of an internal mandrel.
LMT Fette axial rolling heads have two to three, and in special cases up to six, thread rolls with pitch-free profile rings. The rolls swivel along their horizontal axis, so that the workpiece /the rolling head is axially shifted around the thread pitch with a full revolution. Since the rolls "traverse" axially over the workpiece, they can produce threads of any length and with diameters of 1.4 to 230 mm. Together with our customers, we have developed our axial rolling system even further. Discover our newest generation, the EVOline. Its modular design makes it easy to assembly and very reliable.
LMT Fette radial rolling heads were developed primarily for short threads with a very short run-out. They enable extremely short processing times with stationary or rotating workpieces. The LMT Fette radial rolling head traverses axially over the workpiece, independet of feed. With a release mechanism, the rolls penetrate the workpiece radially. The desired profile is generated with a single revolution of the roll. The profile of the rolls matches that of the workpiece being produced. The profile length is limited to the roll width. The LMT Fette radial rolling heads are available with diameters from 3 to 45 mm.
The LMT Fette tangential rolling heads can be used in several diverse applications, such as machines with controlled feed, CNC lathes, or in machining centers. Their high-precision performance enables a short thread run-out and an extremely short threads, even between tips or bedhind a collar. LMT Fette tangential rolling heads have two rolls which contact the workpiece from the side. The rolls form the thread as they move perpendicular to the workpiece during the feed motion. The roll profile corresponds to the profile of the workpiece being produced. The profile lenth is limited to the width of the rolls. The LMT Fette tangential rolling heads are available with diameters from 1.6 to 64 mm.
Knurls are the preferred choice when non-slip or decorative surfaces are required on cylindrical components. As part of a shaft-hub connection, knurls also fulfill several technical functions. They transmit high torques and thus ensure a very good force flow between components. This wide range of application areas makes for different demands on knurl profiles and their quality.
LMT Fette has developed innovative knurling systems to meet your individual requirements and at the same time enable fast, economical and reliable production. With the new tangential knurling system EVOline from LMT Fette it is possible to produce clean and chip-free knurls both in front of and behind a shoulder or a disturbing contour. Even particularly small distances from a shoulder are no problem with this solution.
LMT Fette peeling heads allow you to cover a special area of application: the peeling of the initial diameter to ensure chipless thread production. Use this high-performance tool with indexible inserts to efficiently reduce the diameter of round material and profiled material with a diameter range of 2 to 50 mm. The peeling heads have short production times with high cutting speeds and large feeds. This way, you can achieve narrow production tolerances and excellent surfaces. This system is easy to implement and operate and has a long tool life with low maintenance effort.
We would be happy to provide you with more information.
