Fillet weld grinder solution for grinding tubes

THE ‘low long-neck’ fillet weld grinder is a new addition to Suhner’s range of special tools for abrasive stainless steel working. The UKC 3-R fillet weld grinder is suited to working on hard-to-access fillet welds – a

problem zone often encountered on vessels and railings around tubes. It is based on a 500W motor, and has a speed range of 1,400-3,300rpm. This high torque is strong enough to provide the

optimal drive for modern high-performance abrasives. The motor is characterised by a high power density in a small volume. The stator winding is protected with additional insulation from abrasive grinding dust, to prevent motor damage and enhance the useful life of the tool. A digital electronic system assumes control and monitoring functions for the motor. This accessory ensures a gentle start-up, and prevents motor overheating and unintentional start-ups after a voltage drop. The fillet weld grinder weighs only 1.8kg. For minimised tool weight and optimised manoeuvrability, a very low long-neck angled head was developed, made of diecast aluminium for strength and low weight. Robust spindle locks allow abrasives to be exchanged safely and easily in a short time.

ITALIAN company Ritmo SpA, a leader in the manufacturing of welding machines and tools for plastic pipes and sheets, has presented three new products – rerounders for plastic pipes. The mechanical thread of these steel-made products helps remodel the ends of ovalised pipes that need to be welded by electrofusion. The manual clamping of the tool stems pushes the ovalised end till its reshaping

respects the ovalisation range required by most standards, therefore allowing its insertion into an electrical coupling – and avoiding the cost of eliminating a good pipe. The three rerounders cover the following diameter range: 250-400 model for OD from 250 to 400mm; 450-560 model for OD from 450 to 560mm; and 630-800 model for OD from 630 to 800mm. Each one is sold separately, with a steel transport box.
