Multi-Grind
G r i ndi ng
Universal Grinding Machine
Ideal for tool and die construction, mechanical production, design processes, laboratories and training
When we designed the KNUTH Multi-Grind, our goal was to combine all functions of cylindrical, surface, and tool grinding into one machine. The functionality of the Multi-Grind ranges from external and internal cylindrical grinding to taper grinding. The Multi-Grind also allows easy tool grinding (sharpening of cutters, reamers and turning tools) and is suitable for light surface grinding jobs
Three-Point Bearing The custom three-point bearing of the grinding spindle ensures minimum temperature effects and consistent grinding quality. Feed Drives Hydraulic table feed (longitudinal) with automatic change of direction. An additional manually operated longitudinal feed with hydraulic support allows feed speeds up to 7 m/min. Grinding Headstock Special grinding headstock design allows simultaneous setup of 2 different grinding wheels. The grinding headstock travels transverse, is height adjustable, and swivels around the vertical axis. Speeds The headstock operates at 3 different speeds (110, 200, 300 rpm) which are set through an easy to operate gear shift lever.
Additional Features ... • Central lubrication system • Sturdy construction – the KNUTH MultiGrind body is made of solid cast-iron and weight 1300 kg; minimizes vibration effects • Electrical components are mounted easily accessible in a control cabinet and conform to VDE regulations
• an extensive assortment of accessories, incl. coolant system (delivery up to 22 l/ min.), and vacuum system are standard equipmenmt
