MM1 computer-controlled pipe cutting machine THE MM1 is a computer-controlled machine that automates the cutting of profiles, holes and shapes on pipe with diameters from 10 to 40cm (4" to 16"). It rotates the pipe on its roller bed with a three-jaw chuck, while simultaneously moving a cutting torch back and forth along the pipe’s axis. Pre-programmed shapes such as saddle, hillside, lateral and mitre cuts can be made by simply selecting the type of cut from the menu, then entering the diameters of the pipe being processed and pressing the run button. Templates are not required, and there is no time-consuming layout or calculation. Irregular or uncommon shapes can be plotted, programmed and saved for future use. The machine’s pipe bed is designed for handling lengths of pipe up to 1.83m (6ft). Additional pipe bed extensions of 2.44m (8ft) can be added to make a bed of up to 11.6m (38ft). The method of cutting can be oxy-fuel or plasma. If oxy-fuel is used, the machine will be equipped with solenoids and a three-hose cutting torch. When plasma is used, a rotary ground is installed on the machine. The machine can be delivered with plasma torch leads and power source, or the customer may Tube end conditioning machine from the UK AS part of its ongoing innovation programme, Nuke Tool has announced the introduction of the Sidewinder tube end conditioning machine. The Sidewinder is a machine dedicated to the power and process industry, and especially to those involved in the manufacture and repair of boilers, shell and tube heat exchangers, condensers, economisers, element and membrane wall panels. In operation, the Sidewinder pilots within the bore of the tube while its powerful conditioning motor orbits the outside diameter, carrying out the cleaning/polishing process. Tube sizes from 19 to 88.9mm (0.75" to 3.5") can be handled, and the whole procedure is carried out in seconds. The Sidewinder is a pneumatically operated unit (electric drive option available), and supplied in a double walled, injection moulded case, complete with low speed pneumatic drive motor, choice of three pilots, and a choice of three conditioning heads.
