Index Corporation’s MS40C is a CNC multi-spindle for virtually unlimited operations on small workpieces from bar as long as 40-mm (1.57”) diameter or for chucking as long as 120 mm (4.7”). With six fully independent liquid-cooled, hollow-shaft CNC spindle drives each capable of as much as 7,000 rpm, the machine includes a main spindle drive with increased stiffness, and hydrostatic guide bushings on each carrier slide, which eliminate wear and the transmission of vibration to the tool, the company says.
The main spindle provides quick acceleration and high torque, helping to reduce cycle times. With liquid cooling, spindle and drum cooling is accomplished away from the work area through a local or central cooling system; heat can be released into the plant to use heat energy or outdoors to lessen the summer cooling burden.
Across the range, the machine can be equipped with as many as 35 axes, 12 identical CNC tool carriers with one or two axes, plus one or two 10,000-rpm synchronized spindles with 150-mm travel in the Z axis, and as many as six tools for backworking. Two tool slides approach each spindle, permitting two tools to be simultaneously in the cut on each part.
For longer parts or more backworking, the MS40P version will be available sometime durring 2010.
