Flat bed CNC lathe enables parts up to 554mm diameter by 2000mm long to be swung over the bed or up to a massive 830mm by 216mm within the gap bed.

The Colchester MultiTurn 4000 flat bed CNC lathe enables parts up to 554mm diameter by 2000mm long to be swung over the bed or up to a massive 830mm by 216mm within the gap bed. The machine provides the full advantage of the latest Fanuc control that is equally useable for single part manual cycles or under full CNC control for repeat batches of parts. Now available from Colchester Lathe of Heckmondwike, West Yorkshire, the 3.6 tonne, larger capacity MultiTurn embodies all the features and advantages of the highly successful 1000 and 2000 versions launched last year.

However, with more powerful spindle and servo drives fitted to the machine, this enables effortless cutting cycles to be performed on larger part sizes.

The MultiTurn CNC lathe is very competitively priced and provides high levels of functionality that takes full advantage of the 11kW spindle drive.

The spindle is carried on a cast iron flat bed with an eight-station 360mm diameter, electrically indexing turret capable of holding 25 mm by 25mm tool section size and 40mm diameter boring bars.

Quick-change toolposts from Parat, Multifix or Dickson are available on request.

The success of the smaller MultiTurn versions has been from the ability to combine the versatility of full CNC, electronic and manual operation through Fanuc's latest Series OiTB CNC TFT contouring control with Manual Guide Oi conversational programming.

The machine uses twin electronic handwheels to manipulate the Fanuc digital drives package and, with the simple and quick conversational programming, is directed at users requiring additional large CNC capacity or small batch size component turning solutions.

In addition, it will be equally productive as a universal turning machine to the workshop requiring a solution to the wide range of turning operations faced by a general machinist.

Prime considerations are high flexibility to replace or upgrade existing machining capacity with a reliable and modern, high quality, metal cutting machine without compromising the investment budget.

Three-jaw geared scroll or four-jaw independent chucks up to 405mm with a 104mm bore define the capacity of the machine which can also be supplied with travelling or stationary steadies up to 308mm capacity.

The tailstock is No 6 MT with 145mm travel and is available with heavy duty or general purpose centres.

The ergonomically positioned travelling Fanuc OiTB control has an 8.4in TFT flat colour screen with a 10 GByte hard disk and electronic handwheels for manual operation.

These can be used in conjunction with Manual Guide Oi programming with combinations of advanced canned cycles such as stock removal, threading and grooving to create a fully integrated operation.

Automatic cycling direct from memory gives a full CNC capability from within the fully interlocked enclosure with twin slide-aside guard doors.
