Cutting, sawing & prof i l ing technology

Circular saw blades 50 YEARS’ experience in metal cutting circular saw blade production, along with constant technical cooperation with pipe producers and machine manufacturers, enables Stark to offer the high performance Olympic line, fully

In recent years, tube processing technology has changed greatly. Steel’s higher tensile strength values, greater tube thickness, and faster production line speed are often required by customers. The range includes Olympic 100, suitable for hard material, cutting with low vibrations; and Olympic 200, suitable for stainless steel cutting. Stark Olympic also includes a range of TCT circular saw blades suitable for orbital cutting machines. For cutting tubes with large dimensions, customers are increasingly using orbital cutting heads equipped with two to four blades. Stark developed a new PVD-coated resharpenable blade with special tooth shape, with the aim of reducing the effort during cutting and to reach a longer tool life. According to the section and the material to be cut, Stark can supply different toothing geometries, specially developed to obtain the highest cutting performance.

dedicated to tube cutting applications. The range includes three kinds of blades: HSS circular saw blades; throw-away TCT saw blades; and resharpenable TCT saw blades. The HSS circular saw blade is an

alternative to TCT saw blades for tube cutting. Its special steel and PVD coating allow it to be used at the same peripheral speed as TCT circular saw blades. The feed rates in the central area of tube crossing are claimed to be 40 per cent higher than feed rates of TCT saw blades, and so the blade cuts thin tubes 20 per cent faster than TCT saws. It is suit- able for carbon steel, alloyed steel with high tensile strength, stain- less steel, stainless steel and non-ferrous materials.

of pipe lengths and quantities is generated by an ERP system and is sent remotely to the Haven cut-off, which automatically adjusts for length via a servo- controlled linear actuator. After the pipe is cut, it is transferred to a length- measuring station

A COMMERCIAL fire sprinkler system company has chosen Haven Manufacturing to design and build a tube cutting and length inspection line that will integrate with its downstream threading process and with the factory ERP system. Being a liability-sensitive industry, sprinkler systems are built to very stringent safety and production guidelines. A sprinkler system is made up of three primary components: header, down pipe and sprinkler head. In this application, the Haven Model #873 Servo dual-blade shear cut-off cuts and inspects for length accuracy prior to the down pipe entering the threading process. Generally, the down pipe is made in sequence to the overall system layout. This means that one tube at a time is cut and threaded, and then labelled for part number and installation sequence identity. The menu

to verify that the pipe matches the original input. Since each pipe could be a different length, the measurement system must also automatically adjust to accept the new pipe. This is also done through a servo-controlled linear actuator. The pipe is then transferred to the customer’s threading operation,
