''MAKA'' CNC Machining Centre CR 27 with 5-Axis Technology

Maka-CR27t.jpg

for high-speed machining of wood-derived products and aluminium.

The design of the CR 27 is based on a field-proven concept. Machines with stationary gantry enable high travelling dynamics and thus stand for first-class routing results. This series meets the high standard of those manufacturers requiring three-dimensional machining and machining on multiple sides. This machining centre has been designed for precise machining operations and is used in the vehicle and vehicle equipment industry, by manufacturers of components for technical products as well as by manufacturers of furniture. The CR 27 for the machining of aluminium is of special design and specifically suited to the requirements of light metal machining.

Dynamic rigid design, a high-duty routing unit and a large tool magazine together with the field-proven 5-axis technology allow complete machining operations with only one clamping. Due to the machine design with mobile tables, precision is achieved with high dynamics. A special tool place for a saw blade with a max. dia. of 450 mm can optionally be provided in the chain-type tool changer. A vertically adjustable protection and extraction bin reduces the danger from ejected chips and dust.
