The core component is a diamond blade that cuts the concrete at high speed.Powered by gasoline engines or electric motors via belt or direct drive.Equipped with automatic propulsion for straight cuts.An integrated water spray system cools the blade,reduces dust,and extends blade life.Cutting depth is precisely adjusted via a handwheel.A front guide wheel ensures accurate cutting direction.Larger models are self-propelled;smaller ones are walk-behind.
Specified by blade diameter(e.g.,14",18",20")and engine power(e.g.,7HP,13HP,22HP).Max cutting depth is about one-third of the blade diameter(e.g.,500mm blade cuts~180mm deep).Travel speed is adjustable.Spindle speed typically ranges from 2000-4000 rpm.Machine weight ranges from tens to hundreds of kilograms.
Primarily used for cutting control joints in large-area concrete works like pavements,floors,airport runways,and plazas.Cutting is typically done 1-2 days after pouring when the concrete has gained sufficient strength(approx.10-15 MPa)but is not fully hardened.Proper jointing is crucial for crack control,ensuring project quality and appearance.
