Overview
The INDEX MS16 is a high-speed CNC multi-spindle automatic lathe designed for 16mm maximum bar capacity, targeting the mass production of small-diameter precision turned components at the highest sustainable output rates achievable in CNC automatic machining. The MS16 addresses the miniature precision parts segment where annual production volumes reach tens of millions of parts and where any improvement in cycle time translates directly to significant cost reduction.
At 16mm bar capacity, the MS16 serves the production of miniature precision components: small automotive fuel system parts, electronic connector pins and contacts, watch and clock components, miniature hydraulic fittings, and precision medical device sub-components. These applications share a common characteristic—extremely high annual volumes of small, precise, and relatively simple parts where the multi-spindle throughput advantage is most pronounced.
The MS16's high-speed design enables spindle speeds appropriate for the small diameter work where surface speed requirements drive RPM high. Multiple spindles operating simultaneously maintain continuous part output, and the CNC control provides the programmability to accommodate part family changeovers that cam-type machines in this size class cannot match. Live tooling positions within the multi-spindle cycle enable cross-drilling and threading operations without secondary machine transfer.
INDEX's precision German engineering ensures that the MS16 maintains dimensional consistency across extended high-volume production runs. Thermal compensation, precision ground components, and controlled machine dynamics deliver the part-to-part repeatability required for automotive quality programs even in the demanding high-RPM environment of 16mm production. For the highest-volume miniature precision parts programs, the MS16 provides state-of-the-art CNC multi-spindle production capability.

Frequently Asked Questions
01
A new INDEX MS16 typically ranges from approximately $500,000 to $800,000 depending on live tooling configuration and options. The investment economics depend entirely on annual production volume—the MS16 is cost-effective only for programs producing millions of parts per year.
02
The MS16's 6-spindle configuration reflects the optimization for 16mm capacity work. At small diameters, 6 spindles provide sufficient process segmentation for most 16mm parts without the additional mechanical complexity and machine size of an 8-spindle design. For 16mm work, the bottleneck is typically surface speed and chip management rather than the number of spindle positions.
03
Free-machining steel (11L17, 12L14), stainless steel (303), brass (C360), aluminum (2011, 6262), and similar free-to-moderate machining alloys are the MS16's primary materials. High-speed operation is most efficient on free-machining materials; difficult alloys like titanium and Inconel are possible but reduce throughput advantages.
04
For volumes above ~3-5 million parts per year on a stable part family, the MS16 delivers lower cost-per-part than multiple single-spindle CNC turning centers: one machine vs 5-6 machines, one operator vs multiple, lower floor space, and lower tooling management complexity. Below this volume threshold, single-spindle flexibility usually wins economically.
05
The MS16 can include back-facing, back-boring, and simple backworking operations within specific spindle positions allocated for second-end operations. For extensive complex backworking, a transfer to a separate back-end machining position or a separate machine is sometimes required. INDEX applications engineers can evaluate specific part requirements to determine the appropriate machining strategy.
