With 8 CNC spindles, two back-working spindles for rear-end machining, deploying up to 18 CNC slides (X and Z) and additional Y axes. The MS40-8 is ideal for high-volume precision work in the automotive, fastener, connector, and aerospace industries.
The machine handles bar stock through the INDEX MBL40-8 or chuck parts in its 110 mm chuck for machining of pre-formed, forged or extruded parts of up to 80 mm. For simple parts, the machine can be used as a double 4-spindle machine, reducing cycle times in half.
The heart of the INDEX MS40C-8 multi-spindle automatic lathe is the compact spindle drum with eight fluid-cooled motorized spindles with synchronized technology (max 7,000 rpm, 24 kW, 57 Nm). They are characterized by infinitely variable speed control, high torque, low size and no maintenance requirements.
With the increased number of main spindles and tool carriers, the MS40C-8 is able to completely machine even very complex parts in one operation. Up to two pivoting synchronized spindles are each able to work on up to seven rear end machining tools: four of them can be live. A new feature is that two rear end machining tools can work simultaneously on the workpiece.
If components need to be cut with only a small number of tools, it can be used as a highly productive double four-spindle machine. If the user makes this choice, he has practically two four-spindle machines available of which each provides a synchronized spindle for rear end machining. Each cycle finally outputs two finish-machined components from the machine.
Optimum cutting speeds for each spindle can be programmed for each spindle position and cutting tool edge. The results are optimum metal removal rates, maximum surface quality, short production times per piece, and extended tool life.
The C-axes available in all spindle positions also permit complete machining of intricate workpieces in minimum time. Optional Y-axes expand the range of machinable workpieces further.
Because users can set up live tools on the compound slides, multiple machining operations can be accomplished: off-center drilling, thread cutting, inclined drilling, cross drilling, contour milling, hobbing, bevel gear cutting, and multi-edge turning and more.
