Turner Machine Company, Inc. offers several choices of machinery for straightening metal tube. Specifically, the range of machines covers machines with 6 or 10 rolls. All of our machines feature pairs of vertically opposed driven rolls. 6-roll machines can straighten to at least 1 in 1000, and 10-roll precision machines straighten to at least 1 in 2500.
In 1984, Turner acquired the Mackintosh-Hemphill USA product line followed in 1994 by the products of Wyko England.
New machines generic to Mackintosh-Hemphill maintain 900 model designations (examples being 916, 920, etc.). Machines generically related to Wyko continue to use the designation WS (examples are WS4 / WS104, etc.).
With this rich heritage, we are able to ensure we can provide the best machine to straighten a diverse range of tubes and qualities required to suit the 21st century.
6-roll tube straightening machines
Our history in the production of 6-roll rotary straightening machines goes back to the dawn of tube straightening. For many applications, 6-roll machines will continue to be the standard machine in use around the world.
special straightening applications
10-roll tube straightening machines
Turner has been the forerunner is the design and manufacture of 10-roll precision straightening machines for several decades. The majority of these units are fitted with our famed CASAM system making setting up for a new tube size a quick and painless operation.
Complete Precision Straightening Lines
Turner designs and manufactures complete precision straightening lines with the tube handling equipment fully integrated into our range of smaller 10-roll CASAM (computer aided setting and management) powered machines.
Turner often processes requests for nonstandard straightening applications. Our engineers welcome the chance to demonstrate their inventiveness and skills to come up with special designs and features to solve specific special and unusual straightening applications.
setting and management
The Turner CASAM system is recognized as the world leader in computer control of straightening machines.
Developed 1988, CASAM was the world's first dedicated system to automatically set and manage a tube straightening machine. The system enables the straightening machine to be rapidly changed from one tube size to the next. When fitted to a fully motorized machine, CASAM can automatically change tube size in less than one minute.
CASAM provides very accurate roll positioning and ensures that each operator sets the machine with recorded, known-to-work roll positions. Tube quality is maintained from batch to batch due to using proper roll positions. Small batch production with many size changes per shift is now viable.
The majority of 6-roll and 10-roll tube straightening machines are now shipped equipped with CASAM. After two decades of careful honing, the CASAM system is the most highly developed and user friendly system available. It is available on all Turner tube, bar and roller section straightening machines.
plc & hmi operator control
All of our Machines can be fitted with PLC/HMI Controls for ease of use, customization, and modernization. The machines are able to be fitted with either Siemens hardware or Allen Bradley hardware, allowing the customer to have freedom to choose the system that would integrate best in their facility.
The use of PLC/HMI Controls allows for a fully customizable experience for the customer. This gives the customer the ability to tailor the system to fit their specific needs when it comes to production and operation.
The majority of 6-roll and 10-roll tube straightening machines are now shipped equipped with PLC/HMI Controls. Each system is carefully tested during the building process to ensure a trouble free installation. While on-site during installation, the PLC code can be modified to suit the customers requests to provide the customer with a system that performs to their changing needs.
Along with incorporating PLC/HMI control on new machine builds, Turner Machine also provides service on all of the machines equipped with PLC/HMI controls.
entry and exit
The operation of straightening machinery has a critical dependency on the entry and exit equipment to feed the product into the machine and collect it as it comes out on the exit side. The main purpose of this equipment is to safely handle the product and do so without causing damage or marking.
At Turner, we have extensive archives detailing many different handling equipment schemes which have been used successfully for decades. Maybe it is a simple low speed off-line application that needs equipping or an ultra high speed line that feeds tubes into an in-line facility which straightens at 200MPM / 600FPM. Turner has the designs and the expertise to customize and fit to the customer's precise needs.
Be assured that we can provide the best entry and exit handling equipment to straighten a diverse range of products.
The 900 series of Turner / Mackintosh-Hemphill rotary tube straightening machines were first introduced in the early 1960s. There are now hundreds of 900 series straighteners in regular production and, when maintained in good condition, give very acceptable results to many tube producers. The 900 series machines are very robust and modern versions, some with CASAM computer control. They are manufactured in good numbers each year.
Turner offers a "rebuild back to as new" service and usually need machines in our Salem facility for about 8 weeks. Unfortunately, for many users, that down time prevents having the machine factory rebuilt. To address this problem, Turner operates a straightening head core exchange program.
The straightening head comprises that portion of the machine containing the rolls and all roll adjustment mechanisms. The supplied factory re-manufactured straightening heads are "as new," include all the modern revisions such as digital roll position indicators, and come with a 12 month warranty. The core exchange straightening head can usually be installed in a few hours with minimum downtime for the user.
Our range of section straightening machines are roller type configured with single or dual planes containing close spaced straightening rolls. This range of machinery is generically from Wyko, and we continue to use the WRSS (single plane) and the 2WRSS (dual plane) model references. These are heavy mill duty machines suitable for high production and long service life. The mechanical design of each model features cartridge mounted rolls each having its own bearing lubricant reservoir.
These machines feature the latest Turner refinements to add the CASAM system. With CASAM, these normally hard-to-set machines become user friendly and can be set quickly by a trained operator. State of the art electrical control packages further bring these excellent machines into the modern era of automated machinery.
The machines are complimented by a wide range of section handling equipment that can be customized to suit customers' needs. The majority of metal sections--square, rectangular, hexagon, solid, or tubular--can be straightened with an appropriate machine model.
The work rolls are a vital part of any straightening machine. At Turner, designing and optimizing roll profiles is a science where the combined knowledge of hundreds of applications is bought to bare using advanced computer algorithms to determine the appropriate profile that correctly covers the range of sizes that the customer processes through a specific size of machine.
New rolls for the majority of applications are manufactured from tool steel, then hardened and ground to computer generated and optimized profiles. We also manufacture rolls in tungsten carbide for straightening hard and abrasive alloys when the customer can justify the much higher cost.
When using a Bronx, Sutton, or other older machine, we reverse engineer and manufacture rolls that will perform better than the OEM equivalent.
Our extensive archives of machine build specifications and drawings of machine parts stretches back to the early 1940s. Any straightening machine built under the trade name of Mackintosh-Hemphill can be supported with parts made to the OEM specifications. If you have the serial number, we can supply the mechanical part.
We also have all the drawings for every machine made by Wyko Equipments Ltd., England. No matter whether the machine was built by Mackintosh-Hemphill, Wyko, or Turner, we can supply the required part.
