Turks Heads

The Turks Head is a metal forming machine. It may be compared to an adjustable draw die but is actually infinitely adjustable within its limiting dimensions.

Advantages of a Turks Head:

To those unfamiliar with this type of equipment, the question naturally arises – “Why use a turks head in place of other drawing methods?”

  • Turks heads permit forming directly from round to square, rectangles and special shapes
  • A turks head can take a bigger reduction per pass, when compared to other forming methods
  • Because the rolls are infinitely adjustable there is great flexibility in production capabilities
  • Lower maintenance costs since rolls can be reground for continued use
  • Turks heads maintain uniform tolerances
  • The turks head rolling principle produces less inherent friction

Turks heads are used for the direct formation of round material to squares, rectangles and special shapes. A turks head machine operates on the rolling mill principle and imparts the same qualities to metal as a rolling mill does: superior surface finish, accurate size and shape, and improved grain structure of the metal. However, turks heads differ from rolling mills in the number and arrangement of rolls. A turks head utilizes two pairs of rolls, one pair is arranged horizontally, while the other is arranged vertically. The material is formed and shaped through the turks head by either a pulling device such as a capstan, or by driven rolls in power-driven models.

Each type of FENN turks head is designed to meet a particular requirement of precision wire or rod shaping. With the exception of power-driven models, all types require a pull-through power source such as a drawbench, bull block, double capstan, a shedding drum or a rolling mill. In both ferrous and nonferrous metal forming industries, turks heads are used as single units and in tandem on common stands for wire and rod shaping.

TYPES OF FENN TURKS HEADS:

Universal Models: Includes 2 axes of adjustment: moves up & down, and in & out. Any square or rectangle within the capacity of the turks head can be set up by merely adjusting the position of the rolls; easiest for set up of standard width and thickness.

Plain Models: Includes 4 axes of adjustment so each roll moves independently. Because rolls are set up directly in line with each other, plain models are best for producing special shapes.

Combination Models: Includes 6 axes of adjustments. Can be used as either a U-type or P-type turks head. Provides the most flexibility in setting up the rolls.

FENN turks heads can be power-driven, pull-through, or mill type.

Pull-Through Turks Heads: Require an external pulling device, such as a capstan.
Advantages Include:

  • Tension applied to the material by the pulling device minimized camber
  • Capable of running speeds up to 1,500 FPM
  • Easy roll adjustment
  • Rolls can be reground, promoting longer usable life and lower maintenance costs

Power-Driven Turks Head: Eliminates the need for a pull-through device.
Advantages Include:

  • Less floor space is occupied without a pulling device, such as a capstan
  • Elimination of a capstan reduces material waste, saving precious metal and scrap
  • Top and bottom configurations allow for direct roll drive
    • Direct roll drive is better for constant tension on delicate, low tensile product
  • Easy roll change technology utilizes gear mesh systems which allows for quick removal of the roll without disconnecting joints
  • Regrindable rolls promote longer usable life and lower maintenance costs

Turks Head Mills: Used to create a profile for large wire, rod, bar or strip.
Features Include:

  • Standard models include top and bottom roll direct drive
  • Customized software available to meet your specific production requirements
  • Gauging and closed loop feedback systems can be incorporated
  • Can be made as standalone units or part of a much bigger line
  • Mill solutions are available for a variety of materials
Available Turks Head Options:
  • Manual Fine Adjustment Gearbox: Connected to the adjusting screws, it enables high accuracy and precision adjustments.
  • Motorized Adjustment: Servo motor and gearbox are connected to an adjusting screw. Encoders built into the motors relay the position for precise control of width and thickness.
  • External Coolant System: Can be incorporated for temperature control in complete lines.
  • Asymmetric Rolling: Available on Power-Driven and Turks Head Mills, allows operator to drive top and bottom rolls at different speeds to prevent bowing of material.
  • Guiding Systems: Ensures accuracy and alignment with rolls of input material.

To obtain high production speeds and hold tolerances within acceptable limits, certain basic operation rules must be followed. Proper application of the machine equipment is very important, the turks head is not intended to be a substitute for a rolling mill – but can be combined to accomplish certain applications. Particular fundamental rules are applicable to both machines were size control, surface finish, accessories or combination use is applied.

SIZE CONTROL
The unique design and construction or interlocking slides permit infinite adjustment of the turks head rolls. Within the physical size of each turks head, FENN has engineered the highest possible bearing capacity using precision heavy-duty bearings. Built with extreme accuracy by FENN’s highly skilled craftsman, FENN turks heads (when properly used) form sections to close tolerances.

SURFACE FINISH
Although surface irregularities cause no particular difficulty, a higher quality entry stock will result in a better finished product. It is important to remove oxides and scale as this build up will cause the rolls to wear more rapidly. It is further recommended that lime coatings be removed from wire prior to forming, since it tends to build up on rolls and causes separation and consequently tolerance changes as well as bearing overload.

STANDARD AND CUSTOM METAL FORMING SOLUTIONS
FENN manufactures a range of precision pull-through and power-driven turks heads with high bearing capacities at high speeds. Our design and manufacturing engineers ensure that our metal forming machines hold close uniform tolerances on shaped wire. FENN can design and build customized turks head equipment to act as standalone machinery or be integrated into an existing or new process.

FENN’s people made the difference.

Our business was looking to continue the progression of new and improved equipment to meet the changing needs of our customers. We chose to work with FENN on this project because of their willingness to collaborate on design features to meet our specific requirements for a machine of this size. This was a 15-month process from initial discussion to final program sign-off and machine installation. Communication was excellent throughout the building process. We were able to collaborate on any items, whether it was with FENN’s executives or directly with the machine builders. As with any custom first-off machine, there were minor issues that needed to be addressed. FENN corrected each of these and provided dedicated staff and resources to do so, which is one of the reasons we chose them for this project. The machine is actually exceeding our expectations. After having gone through a similar project 10 years ago, the FENN team improved all aspects of this project – from communication to delivery to the final product. From the initial outreach and conversation with the executive team, all the way through the delivery and minor issue corrections, it was done with people. FENN’s people made the difference. Since the beginning, a very important part of our decision making-process was wanting to work with a company that closely resembles the culture of our business and FENN met and exceeded our expectations.

FENN was very easy to work with

We decided to have our worn-out W-125SA Torin mechanical coiler retrofitted to a 2-axis servo coiler because our production required more feed length than a standard mechanical offered. We have other FENN-Torin coilers in our shop and are pleased with the support and customer service. The 2-axis retrofit has met our expectations as far as ease of set-up, since there was really no learning curve to the set-up and programming of the retrofit. We are now able to take spring production jobs we couldn’t run before on the mechanical W-125SA. FENN was very easy to work with during the retrofit process, keeping us updated on progress of the rebuild with pictures and a video of the finished machine. We recommend the Torin retrofit program as an economical way of rebuilding used FENN-Torin coilers, it was the right choice for us. We are also purchasing a rebuilt/retrofitted FENN-Torin FZ-115 6-axis coiler, to be delivered in February 2020.

FENN-Torin is our choice

In 2018 Mann-Hummel decided to replace an outdated cam driven spring coiler on a high-speed valve assembly machine. We use these valves in our oil filters for O.E. and Aftermarket customers. The equipment had become inefficient and spare parts were becoming difficult to find. The age and design of the equipment also made it difficult to train new personnel. We recognized it was time to modernize. We are not experts in making springs, so we had to increase our knowledge before making this important purchase. We researched on the internet and contacted several spring suppliers. After making several contacts we decided to observe several brands of spring coilers in a production environment. This also gave us the opportunity to ask questions about the equipment they had purchased. After talking with several spring technicians in the field we decided on a FENN-Torin Spring Coiler. Our Torin coiler has been in use for about a year now. Efficiency has increased and overall equipment repair cost is down. Although there have been learning curves with the new equipment FENN-Torin has supported us every step of the way. We are currently looking at a second coiler coupled with an assembly machine. FENN-Torin is our choice.

Top-Notch Machines

In 2009 we decided to purchase our first ‘Z’ CNC Coiler. The efficiencies gained by reduced setup time, increased throughput, and significantly reduced scrap rate while holding extremely tight tolerances was immediately realized through a complete statistical analysis. The machine paid for itself within months. Success with our first Torin ‘Z’ CNC led Springfield Spring to purchase another ‘Z’ CNC coiler, followed by three more of the latest model, the Torin FZ Series. Our five newest Torin spring coilers replaced all of our mechanicals, freeing up substantial space for new business endeavors. Fenn not only produces a top-notch machine but their sales, service, applications, and technical professionals are second to none. Fenn acts and responds like a business partner, not your traditional machine ‘dealer’.
