Automatic punching machine THE PA-80 automatic punching machine from SMS Engineering, Italy, is suitable for punching steel, stainless steel and aluminium bars with round, square or rectangular section. It can produce round and square holes with or without deformation, and it is suitable for producing components for shelving, radiators, ladders, bed frames and similar products. Punching can be done to one side, two opposite sides, or alternate

opposite sides (pitch is variable). The main features of the machine are pitch precision, straightness of the worked bars and fast change of the tooling. The operator only has to load the piece on the machine at the right position and push the start button. The machine is composed of a heavy, electro-welded steel frame; a trolley equipped with special clamping gripper; special punching units; controlled axis to manage all tube movements; hydraulic power pack; and an electrical cabinet supplied with control panel and electrical installation. The maximum tube size is 80mm, with a standard length of 3m (with options for 4, 5 or 6m); punching power is 3, 6 or 10 tons.

Rotary pipe scrapers RITMO’S RTC 160, RTC 315 and RTC 710 are rotary scrapers for preparing plastic pipes and fittings before electrofusion welding.

length, most useful when carrying out on-site repairs. The PS 180 has an external working range from 75 to 200mm, and a maximum length of 129mm; PS 400’s working range is 137 to 426mm, with maximum length 150mm.

maximum length 137mm. The PS line consists of two models: PS 180 and PS 400. These easy-to-use rotary scrapers are also used to prepare plastic pipes and fittings before electrofusion welding. The tools have an adjustable chuck covering the whole working range, and a blade holder orbital arm. The PS series ensures a constant and regular removal of the shaving. The scraper’s blade holder allows the scraping of the entire electrical sleeve’s

The pipe scrapers remove the oxidation layer caused by weather and ultraviolet rays. If not removed, this oxidation layer would compromise the quality of the joint. Among the main construction features is a device that makes it possible to maintain a constant thickness of the continuous chip, even if the pipe is misshapen, and to adjust the length of the surface to scrape according to the depth of the electrical coupler. The RTC 710 features an extendable arm to scrape the exact length of the electrical coupler, which is an advantage when having to perform maintenance/ repair jobs on a building site. The main chuck has four extendable arms that directly clamp the inside diameter of the pipe. The external working range is Ø 355 to 710mm, and the maximum length is 530mm. RTC 160 has a working range from Ø 50 to 160mm, with maximum length of 114mm; and RTC 315’s working range is Ø 75 to 315mm, with
