Discs for grinding and cutting steel
Two new abrasive discs from Tyrolit offer improved performance characteristics for freehand grinding and cutting.
The latest product launches from Tyrolit include the Silentio grinding wheel, which combines maximum stock removal rates with long life and noise reduction of more than 10dBA. The sound level as perceived by the operator and others in the vicinity is said to be halved. The resinoid-bonded, fibreglass-reinforced wheel is a Tyrolit 3-star premium product, introduced during the manufacturer’s recent rebranding exercise of its entire range. The wheel is said to be ideal for working on steel and stainless steel to a maximum speed of 80m/s and has a novel damping feature for better run-out. Four diameters are available in the range 115 to 230mm. As an added benefit, vibration is also lower than for other discs on the market, which operators say they can feel immediately they start grinding.
Also new for machining stainless steel at up to 80m/s is the Superthin cut-off wheel, an innovation that the Austrian firm introduced back in 1992. By using specially coated abrasive grain, optimising the bond system and including newly developed fibreglass reinforcement, a dense matrix has been created that promotes safety in use and long service life, despite the wheel’s 1-2mm thickness, depending on diameter (115-230mm). The wheel is free-cutting for aggressive machining and the thin profile has the effect of reducing dust, noise and machine load, leaving a clean, accurate cut with good surface finish. Rough sides avoid the risk of jamming and kick-back during cutting.
