Knuth Machine Tools USA offers the Multi-Grind machine for tool and die construction, mechanical production, design processes, laboratories and training. This grinding machine combines all functions of cylindrical, surface and tool grinding into one piece of equipment.

The machine design makes it easy to grind tools including sharpening cutters and reamers as well as turning tools, the company says. Developed with a three-point bearing system to ensure minimum temperature effect and consistent grinding quality, the machine is well-suited for heavy to light duty grinding jobs. Equipped with three-speed grinding headstock, which allows for simultaneous setup of two different grinding wheels, this machine can be moved in transverse direction as well as vertically.

It can also be rotated around the vertical axis, making it highly flexible for handling continuous and precise grinding cycles.

Featuring hydraulic table feed drives with automatic change of direction, the machine offers manually operated longitudinal feeds with hydraulic support to handle fast speeds as high as 275 ipm. With a maximum grinding diameter of 8” and a maximum workpiece length of 20”, the grinding machine is able to handle internal spindle speeds of 13,500 rpm and external spindle speeds of 2,500 rpm. Built of solid cast-iron and weighing more than 2,800 lbs, the machine is able to thoroughly minimize and absorb vibration, according to the company.

Additional features include an automatic central lubrication system, accessible electrical cabinet, vacuum and coolant systems, three-jaw chuck and manual operation.
