A new era of “single hit” machining
The new, 100% British designed and manufactured heavyweight Colchester-Harrison Tornado TT6 turn-mill centre, with eight-axes, twin 12 station turrets, two identical 15 kW integrated spindle units and a totally redesigned heavy duty bed casting weighing in at 7 tonnes and is the ideal platform for high performance turning and milling operations.

The new Tornado TT6 is a true, twin upper and lower driven tool turret machine, giving the added flexibility of two totally independent but simultaneous toolpaths with higher productivity capability of providing overlapped or twin turning tool sequences.

To ensure maximum stability and absorb the cutting forces and vibration a single three tonne, 45º slant bed casting has been designed and uses a Y-axis wedge-angle configuration for superior strength and rigidity.

To guarantee performance only leading European and Japanese suppliers are used for cartridge spindles, all-driven tool turrets, linear guideways with roller bearings and hydraulic systems. The top of the range servo motors and drives are supplied by Fanuc-GE who also supply the latest, superb 31i-A CNC control with a 10.4 inch LCD screen and high speed low power CNC processor with unique and simple programme prompts and aids.

The Tornado TT6 gives you the ability to machine even the most complex work pieces simply, accurately and without setup changes which will save you time and money whilst guaranteeing accuracy and repeatability, time after time.

  • Reduces component floor to floor cycle time
  • Eliminates waiting time between processes
  • Reduces set up time by up to 25%
  • Shortens lead times
  • Reduces operator time
  • Cuts production costs immediately


The latest, advanced Fanuc-GE series 31i-A CNC control console is mounted on the right and pivots through 90ºfor simple, ergonomic operation to suit all operators. The development by Colchester-Harrison of unique HMI screen’s, with their own menu structure incorporates lights-out production software, simple graphics for tool setting with options for cut/measure or auto-probing and also online help, enhanced diagnostics with identifiable service intervals reminder and auto switch-off when the programmed batch cycle is completed. These unique features make the TT6 control the simplest, yet most powerful control available.

The unique Colchester-Harrison off-line programming package is offered as part of the machine specification to further improve your productivity.

Operators console
- devices are grouped by function in a simple, ergonomic layout which makes it intuitive and remarkably easy to use and understand.
Load meters dedicated to all main spindles and tool spindles for constant cycle cutting performance monitoring.

Simple to use yet powerful software use it to create complex programs and components at the machine easily and simply.

Developed by Colchester-Harrison engineers, the manual guide i customised screens and cycles ensures that knowledge of ISO
language is not needed to master this 100% conversational aided programming system.

M-code & G-code help screens are a quick reference guide when programming at the machine which means you do not have to waste time referring to the manual.

Tool set-up screens for Cutting / Probing can save you 25% on tool set-up time

Periodic maintenance schedule screens tell the operator when the machine is due for service which helps maintain the machine and prolongs machine life

Lights-out screen assists you to monitor tool life & sister tooling.

Un-manned 24/7 machining guarantees increased productivity and efficiency.

The RED LINE turret series is the flagship of the Sauter disc type turret range and features an exceptionally rugged housing, ultra high speed indexing and an extended neck for back turning tools. This turret with single motor technology for indexing and tool drive is an outstanding performer in terms of capability as well as economy and will give you that competitive edge.

  • High performance turret with AC spindle drive
  • Tool drive with spindle orientation
  • Tools individually driven
  • Radial tool mounting

Using the unique Kessler Gamfior synchronous, high torque, dynamic and compact motor spindle throughout the range to give you the best spindle performance figures. This superb motor spindle uses high energy density permanent magnets in the spindle shaft which makes a huge contribution to the superb acceleration and power/weight ratio performance.
