How much does the Colchester Tornado SL30MC / SL30LMC cost?
Price estimate
We do not have a price for the Colchester Tornado SL30MC / SL30LMC that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Colchester Tornado SL30MC / SL30LMC is the mid-size Tornado with a C-axis and driven tools, offered in two bed lengths under one specification column. The driven tools are rated 3.5 kW (4.7 hp) and run to 4,000 rpm. The main spindle has a 65 mm (2.6 in) bore, 15 kW (20.1 hp) and a top speed of 4,500 rpm.
Note how the driven turret changes the envelope. Turning length is listed as 540 / 940 mm (21.3 / 37.0 in), and maximum cutting diameter as 330 mm (13.0 in). On the 2-axis Tornado SL30 / SL30L the same rows read 600 / 1,000 mm (23.6 / 39.4 in) and 400 mm (15.7 in). Swing over the bed, at 600 mm (23.6 in), and swing over the cross slide, at 400 mm (15.7 in), do not change, so the loss comes from the turret and its tool holders rather than from the castings.
All 12 stations take VDI 40 tooling. Driven-tool speed is the main compromise against the smaller machine: the Tornado SL25MC spins its driven tools to 5,000 rpm with the same 3.5 kW (4.7 hp). For drilling and tapping the difference rarely matters. For small end mills in aluminium it does.
There is no Y-axis and no sub-spindle. The longer bed is the reason to choose this model for shafts that also need keyway slots, cross holes or drive flats, with the optional hydraulic steady rest supporting the work. Chuck size is listed as 8 / 10 in (203 / 254 mm) and the control is the Fanuc 0i-TF Plus or Siemens 828D.

Strengths & Limitations
Strengths
- C-axis and driven tools on a machine with up to 940 mm (37.0 in) of turning length
- 65 mm (2.6 in) bore and 15 kW (20.1 hp) main spindle carried over from the 2-axis version
- 12-station turret on VDI 40 tooling, with driven tools rated 3.5 kW (4.7 hp)
- Swarf conveyor, parts catcher, Renishaw tool setting probe and 20 bar coolant are standard
- Robot interface and barfeeder are on the options list
Limitations
- Cutting diameter is 330 mm (13.0 in), down from 400 mm (15.7 in) on the Tornado SL30 / SL30L
- Driven tools top out at 4,000 rpm, below the 5,000 rpm of the Tornado SL25MC
- No Y-axis, so off-centre milling is not available
- No sub-spindle for back-face work

Frequently Asked Questions
01
Turning length is 540 / 940 mm (21.3 / 37.0 in) and maximum cutting diameter 330 mm (13.0 in). The Tornado SL30 / SL30L without driven tools lists 600 / 1,000 mm (23.6 / 39.4 in) and 400 mm (15.7 in). Swing over the bed is 600 mm (23.6 in) on both.
02
Driven tool spindle power is 3.5 kW (4.7 hp) and the maximum driven tool speed is 4,000 rpm. The turret has 12 stations on VDI 40 tooling and the main spindle has C-axis control. Main spindle power is 15 kW (20.1 hp) with a maximum of 4,500 rpm.
03
Chuck size is listed as 8 / 10 in (203 / 254 mm) for the two variants, on an A2-6 spindle nose with a 65 mm (2.6 in) bore. A hydraulic quick change collet chuck is on the options list for bar work, and a barfeeder can be added.
04
Not on this model. The table answers No for both. In the Tornado range the Y-axis and sub-spindle appear on the Tornado SL25 MSY, which has a smaller 52 mm (2.0 in) bore and 522 mm (20.6 in) of turning length.
