How much does the INDEX TNL32 cost?
Estimated price range
Our best estimate for a swiss-type lathe in this class — not a quote from INDEX-Traub. Configuration moves it a long way.
Overview
The INDEX TNL32 is a TRAUB sliding-headstock lathe for bar up to 32 mm (1.26 in) and parts up to 320 mm (12.6 in) long. The main spindle runs to 8,000 rpm and is listed at 6.7 / 10.7 kW with 21 / 32 Nm, and the turret has 10 stations with live tools at 6,000 RPM.
A 320 mm part length on 32 mm bar points to shafts, pins and long turned parts that need the work held close to the cut. C-axis resolution is 0.001 degree, enough to index cross holes and flats with the live tools. Z rapid traverse is 20 m/min. The TNL18 runs 40 m/min in Z, so on small, short-cycle parts the TNL32 spends more time moving between cuts; its case is bar size and part length.
The counter spindle carries 3.7 / 5.5 kW and 29.4 / 43.7 Nm. Its speed is listed two ways, 8,000 RPM and 6,400 rpm maximum, and the main spindle has a second power figure of 5.5 kW (7.4 hp) besides the 6.7 / 10.7 kW above. The counter spindle torque is also higher than the main spindle's 21 / 32 Nm. Get these settled with INDEX before planning back-end operations.
For longer work, the TNL65 lists 650 mm of turning length and 7,000 RPM live tools. The TNL32 itself weighs 7,350 kg and is rated at 28 kW electrical. The control is listed as TRAUB.

Strengths & Limitations
Strengths
- Takes 32 mm (1.26 in) bar and parts up to 320 mm (12.6 in) long
- 8,000 rpm main spindle with 6.7 / 10.7 kW and 21 / 32 Nm
- Turret with 10 stations and live tools at 6,000 RPM
- Counter spindle with 3.7 / 5.5 kW and 29.4 / 43.7 Nm for back-end work
- C-axis resolution of 0.001 degree for indexed cross holes and flats
Limitations
- Z rapid traverse of 20 m/min is half the 40 m/min of the TNL18
- Live tools stop at 6,000 RPM, limiting small-cutter milling; the TNL65 lists 7,000 RPM
- Counter spindle speed is listed as both 8,000 RPM and 6,400 rpm, and main spindle power as both 5.5 kW and 6.7 / 10.7 kW
- Weighs 7,350 kg and needs a 28 kW electrical supply

Frequently Asked Questions
01
Up to 320 mm (12.6 in) from bar up to 32 mm (1.26 in). For longer work the TNL65 lists a 650 mm turning length. The tailstock quill travel row reads 305 / 127 mm; ask INDEX what the two figures cover.
02
The TNL18 is the faster small machine, with 40 m/min Z rapids against 20 m/min on the TNL32. The TNL32 takes 32 mm (1.26 in) bar and runs its main spindle to 8,000 rpm with 6.7 / 10.7 kW, for larger and heavier parts.
03
The counter spindle is listed at 3.7 / 5.5 kW and 29.4 / 43.7 Nm. Its speed appears as 8,000 RPM in one row and as 6,400 rpm maximum in another. Its torque is also higher than the 21 / 32 Nm of the main spindle, which is unusual, so confirm both with INDEX.
04
The table lists a machine weight of 7,350 kg and an electrical rating of 28 kW. The control is listed as TRAUB. Plan floor loading and the power feed before delivery.
