is only 20-30 per cent in comparison to carbide saws. In finishing lines, the cut-off machine can be equipped with tube optimising software, treating each seamless tube individually. After length measuring of each individual tube, the tube is precisely positioned to the required length and cut. Fixed length and random length cutting is standard, in addition to sample cutting and flexible end cutting. The system operation is simple, requiring only the input of length. The company claims that customers have experienced a reduction in scrapped material of approximately 2-3 per cent. The cut-off machines and finishing lines are available in a diameter range from 10mm to 630mm. Reika GmbH & Co KG – Germany rate and required end conditions with minimal adjustment. These machines can create the same cut from the beginning of a production run to the end of the run, regardless of piece count. A highlight of the company’s range is the model #6A and series 500 support system. The series 500 tube support system permits storage of multiple tubes/pipes and easy operator access to the tube feed section of the machine. This system was designed to increase productivity and to be used where the expense of an automatic tube feeding system cannot be justified. The primary benefit is a reduction of loading time of the tubing (multiple vs single pieces) and the improved feeding of the tube into the cut-off machine. Continental also manufactures cut-off blades that are made from high impact tool steel. These blades are heat treated to provide top performance and long life. Blades can be resharpened 25-30 times making the cost per cut nominal compared to other methods that are used to cut pipe or tube.

Rotary tube cut-off machines for seamless tubes

Cutting equipment manufacturer, Reika GmbH & Co KG, Germany, has reported increasing sales as a result of the current boom in the tube industry. Vallourec & Mannesmann, Tenaris, Interpipe and Mittal have purchased several machines for tube cutting in their finishing lines/tube processing departments. and finishing

Reika machines cut seamless tubes with high tensile strength, and are equipped with standard carbide inserts which can be purchased from tool suppliers worldwide. The cutting process is dry, and in the case of high alloys a mini-cooling system can be activated. Benefits of Reika machines include high output and low tool cost, which

Manual and air-operated rotary cut-off machines

Continental Cut-Off Machines, USA, manufactures seven different cut-off machine models based on two methods of rotary cut-off machines – manual and air operated. The company’s machines utilize the rotary concept of cutting tube and pipe without material waste. In use since 1919, this concept has developed into an effective production method for tube and pipe cutting, regardless of lot sizes.

A variety of pipe and tube diameters and lengths can be handled efficiently by both manual and air-operated machine. Manual rotary cut-off machines provide an economical option for shops with intermittent cutting operations or with frequent changeovers for cutting a variety of sizes. Air operated rotary cut-off machines allow each job to be tailored to the production
