Eight-Spindle Automatic Lathe



Accommodating bar stock of up to 40 mm in diameter, the INDEX MS40-8 eight-spindle automatic lathe includes two swiveling synchronous spindles for double rear end machining and deploys up to 18 cross slides with X and Z axes, as well as optional Y axes. The machine is especially suited to manufacturers producing high-volume, precision work in the automotive, fastener, connector and aerospace industries.

The MS40-8 handles bar stock through a newly released bar loader, the INDEX MBL40-8. The machine can also chuck parts via a 110-mm chuck that allows machining of pre-formed, forged or extruded parts of up to 80 mm. For simple parts, the machine can be used as a double four-spindle machine, producing twice as many parts per cycle.

The heart of the INDEX MS40-8 is the compact spindle drum with eight fluid-cooled motorized spindles, each providing 7,000 RPM, 24 kW of power and 57 Nm of torque. 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," said a company spokesperson. The two swiveling synchronous spindles are each able to apply up to seven rear end machining tools, four of which can be live. Additionally, two rear end machining tools can work simultaneously on the workpiece.

A highlight of the MS40-8 is its versatile, economic operation, including for simple workpieces. For example, 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 or she has practically two four-spindle machines available, with each including a synchronous spindle for rear end machining. As a result, each cycle outputs two finish-machined components from the machine.

The MS40-8 accommodates a large number of stationary and live tools for front and rear-end machining. INDEX's front-open design concept does not include a longitudinal slide block and incorporates a V-shaped arrangement of tool carriers on the work spindles. External and internal machining operations using stationary or live tools can be carried out on every station, allowing flexibility in optimizing the machining sequence.

"INDEX applied many of its proven multi-spindle design features to the MS40-8," said the spokesperson. "Each of the machine's spindles use hollow-shaft motor technology, and optimum cutting speeds can be programmed for each spindle position and cutting tool edge. The cumulative effects result in optimized metal removal rates, surface quality, cycle times and tool life."

According to the company, this programmability of each spindle makes it possible to machine troublesome materials that were previously extremely challenging for multi-spindle machines. Speed changes are also possible during drum indexing, resulting in no additional downtime. The C axes available in all spindle positions also permit complete machining of intricate workpieces in minimum time. Optional Y axes further expand the capabilities of the machine.

Because users can set up live tools on the compound slides, multiple machining operations can be accomplished, including off-center drilling, thread cutting, inclined drilling, cross drilling, contour milling, hobbing, bevel gear cutting, multi-edge turning and more.

The MS40C-8 is equally suitable for the machining of bar stock and chuck parts. INDEX's newly developed bar loading magazine, the MBL40-8, is engineered to provide high reliability and process efficiency.

To machine chuck parts, the MS40-8 easily accommodates automatic loading due to its generous work area without a longitudinal slide block. An optional built-in robot within the work area uses a double gripper to handle the loading and unloading of workpieces.
