Overview
The Index MS22-8 is an 8-spindle CNC multi-spindle automatic turning machine from INDEX Werke, a German manufacturer of CNC lathes and multi-spindle machines. Unlike cam-driven multi-spindle automatics, the MS22-8 uses individual CNC axes on each spindle position, enabling rapid changeover and programmable multi-step operations without cam replacement. The machine processes bar stock up to 22 mm diameter across 8 spindle positions, providing up to 8 simultaneous machining operations for very short cycle times on complex turned parts. Index's C-controlled multi-spindle uses Fanuc 0i-MF controllers on each spindle with a coordinating master NC, enabling turning, drilling, milling, and threading in a single setup. The MS22-8 targets automotive fuel injection components, medical precision fittings, hydraulic connector bodies, and electronic connector pins — parts requiring sub-tenths tolerances in very high volumes. With a 22mm maximum diameter, the MS22-8 occupies the small-to-medium precision turned parts segment where both cycle time and changeover flexibility are required.

Strengths & Limitations
Strengths
- 8 simultaneous CNC positions deliver extremely short cycle times on complex parts
- CNC-driven — changeover in minutes vs hours for cam-driven alternatives
- Individual axis servo control enables complex turned profiles at every spindle
- Index's German precision reputation for sub-tenths tolerance in production
- Gantry pick-off standard for automated part handling
Limitations
- Very high capital investment — requires dedicated high-volume production to justify
- 22 mm bar diameter limits to small/medium precision parts only
- Complex multi-spindle CNC maintenance requires trained technicians
- Programming 8-spindle coordinated programs requires specialist knowledge

Frequently Asked Questions
01
The MS22-8 uses individual CNC axes at each spindle position instead of cams. This enables program changeover in minutes, complex programmable profiles at each position, and elimination of cam grinding. Cycle time is similar but setup time is dramatically shorter.
02
Each spindle position can perform turning, drilling, boring, threading, and with optional Y-axis and live tooling, milling and off-center drilling. All 8 positions operate simultaneously, producing a finished part each cycle.
03
On common automotive precision parts (injector bodies, valve spools) with 5-8 operations, cycle times of 3-8 seconds per part are typical. Total production output is 450-1,200 parts per hour depending on part complexity.
