Twelve tools in compact budget lathe
package
The Colchester Tornado 120 three-axis, M-series 600 slant bed CNC mill/turn lathe brings the latest developments from the larger capacity 220 machine into a more compact package.
The Colchester Tornado 120 three-axis, M-series 600 slant bed CNC mill/turn lathe brings the latest developments from the larger capacity 220 machine into a more compact 210mm turning diameter, 52mm bar capacity machine with 12 driven tool positions Central to the competitively priced, driven tool Tornado 120 M specification, is the combination of the flexibility of 12 driven tool positions, its high metal removal and accuracy capability

New driven tool version of slant bed CNC lathe
Colchester's top-selling Tornado slant bed CNC lathe is now available with driven tools; the three-axis 'M' version has six driven positions on the Sauter 12 station turret
Unmanned turning package extended to more lathes
The 'Lights Out' unmanned turning package developed by Colchester is now available on the latest two-axis 220 and three-axis 220M as well as existing A-Series machines in A50 and A90 specifications
High metal removal and accuracy is achieved through the adoption of the patented Duo-stable base foundation and bed construction that significantly upgrades the stability of the turning platform with 25% improvement in damping.
Duo-stable uses a steel encapsulation with a polymer concrete base fill, incorporating strategic reinforcement, which is coupled to a cast iron bed.
The machine features heavy duty slideways which operate in a thermally stable cutting zone.
The Tornado 120 M has a 12-station 30 VDI all-driven tool turret powered by 3.7kW motor giving 5000rev/min with 16.5Nm of torque which is ideal for high performance drilling and milling tasks.
The mill/turn specification includes disc brake spindle positioning for the C-axis drive and from the options list, a hydraulic tailstock with 63mm quill can also be selected.
The main spindle is driven by 15kW Fanuc motor and the machine can be specified with 170 or 210mm chuck size or 52mm bar feed.
Maximum spindle speed is 6000rev/min and rapid traverse rates are 25m/min in the 185mm x-axis which has linear scale positioning for higher accuracy, and 30m/min in the 450mm z-axis.
Turret indexing time is quick at 0.3s, which contributes to the minimisation of non-cutting times.
In keeping with the rest of the Tornado range, options include the 'lights-out' package which incorporates integrated swarf conveyor and Colchester's MBF 1000 bar feed system programmable at the Fanuc 21i-Ta control.
As part of the unmanned running package, a parts-catcher, axis torque tool monitoring, onboard production control software and a graphics-based programming CAM system are featured with Renishaw's component probing system.
