Turks Heads

 

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.

The Turks Head operates on the rolling mill principle and imparts the same qualities to the metal as the Rolling Mill does, namely, superior surface finish, accurate size and shape, and improved grain structure of the metal. They differ from a Rolling Mill in the number and arrangement of rolls. The metal forming machine utilizes two pair of rolls, one pair is arranged vertically and the other pair horizontally. In all types of Turks Heads the rolls are infinitely adjustable.

Each basic 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, a Bull Block, a double capstan, a shedding drum or a Rolling Mill.

To obtain high production speeds and hold tolerances within acceptable limits, certain basic operating rules must be followed. Proper application of the machine equipment cannot be overemphasized. It must be understood the Turks Head is not intended to be substitute for a Rolling Mill, but can be combined for certain applications. However, certain fundamental rules are applicable to both machines where size control, surface finish, accessories or combination use is concerned.

ADVANTAGES OF A TURKS HEAD
To those unfamiliar with the operation, the question naturally arises – Why use a Turks Head in place of other drawing methods?

The following are important advantages that the Turks Head offers:

  • Permits forming directly from round to square, rectangles and special shapes
  • Takes bigger reductions per pass
  • Greater flexibility because rolls are infinitely adjustable lower maintenance costs – rolls can be reground
  • Maintains uniform tolerances
  • The Turks Head rolling principle produces less inherent friction

In both the ferrous and nonferrous metal forming industries, Turks Heads are used as single units and in tandem on common stands for wire and rod shaping. They also used in tandem with Rolling Mills, Bull Blocks and Drawbenches.

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

SURFACE FINISH
Although surface irregularities cause no particular difficulty, a higher quality entry stock will result in a better finished product. Bad surface defects cannot be eliminated completely, and failure to remove oxides and scale 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 the rolls causing roll separation and consequent tolerance changes as well as bearing overload.

CUSTOMIZATIONS NOT OUR ONLY CAPABILITY
FENN Manufactures a range of precision standard pull-through and power-driven Turks Heads with high bearing capacities at high speeds. Our design and manufacturing techniques ensure that our metal forming machines are able to hold close uniform tolerances on shaped wire.

Many years of experience in the design and manufacture of equipment to produce shaped wire gives FENN a big advantage when our customers have unique applications which require custom designed Turks Heads.

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’.
