YOUR OPPORTUNITY TO BUY ONE OF THE FINEST MACHINE TOOLS EVER BUILT

 

WHEN THE MILLENNIUM VERTICAL TURNING CENTRES WERE INTRODUCED 20 YEARS AGO THEY WERE RECOGNISED AS WORLD LEADING MACHINES

 

THEIR SPECIFICATION, RELIABILITY AND PERFORMANCE CONTINUE TO BE RECOGNISED AS WORLD CLASS

 

THIS MAY BE A ONE TIME OPPORTUNITY FOR YOU LOOK AT THE LINKS TO THE SHORT FILMS – THIS IS HIGH PERFORMANCE

MILLENNIUM SERIES 4 - Model 180/200 high speed vertical turning and milling centre

 

High speed turning plus a powerful live spindle and C axis for rotary milling and drilling.

The long cross rail enables tool pick up from two 18 pocket tool magazines

This machine has a very sophisticated specification with a tooling package of very high value.

It was ordered to a specification to enable the manufacture of high precision large marine gears using an extensive range of angular drilling, tapping and milling heads. This tooling package was used in addition to the machine’s high precision turning capability to enable a one stop process, apart from gear cutting.

The  high quality turning capability eliminated bore grinding of the hub.

The tooling package includes 5 adjustable angle Capto driven heads as seen in the film and below

Two 18 pocket heavy duty tool magazines to incorporate 36 tools or attachments

The original cost of this CAPTO tooling package was £139,000

This machine is available following the closure of a major company in the steel industry. The structural condition  is very good, the guideways show minimal wear. Our new machine build experience and our servicing and rebuild experience of Millenniums enable us to refurbish this machine to a very high standard and offer it in very high quality, cost effective formats to suit the users requirement

 

About the Millennium

 

When first introduced the Webster & Bennett Millennium range was immediately accepted as world leading series of vertical turning centres that were purchased by some of the best known world leading companies in the businesses of aero engine manufacture and repair, oil and gas components, gear drives, power generation, rail and defence rocket production

 

The Millennium is world class in its major structures and capabilities and it is a cost effective investment to refurbish the structures and modernise the CNC, electrics, hydraulics and pneumatics

 

The result will be a machine with basic structures of a higher standard than is found in most machine tools built today and this will be coupled with the latest available operating facilities

If you can find the equivalent new machine today the cost will be several times more

SIEMENS 840D CNC Powerline

 

Since it’s introduction 840D has been regarded as the best CNC for complex machine tools.

Perfect for turning, milling, drilling and grinding on the Millennium

 

The system will be upgraded to continue to provide a very satisfactory performance.

We combine it with a new cabinet and new wiring, for maximum reliability performance

 

THE NEW GUARDS

 

The guard designs provide two options – i) standard style 3000mm high open top or ii) new design to totally cover the machine to protect contamination of the cutting zone and equally to  prevent contamination of the working environment outside the machine. Photos below of similar guards taken during a recent installation

 

Benefits of ii) the total covering guards

Installation, commissioning and maintenance is made safer when working at height because we have engineers platforms built into the guard frame (see first guard photo below)

 

The door system is in two parts

The lower doors are the operators safety doors – full protection by the structure and interlocks The lighter upper doors require to be opened only when loading or unloading components

 

PRICING

 

For the machine refurbished and upgraded as outlined above and tested with full functions and operating tests in VTT, dismantled and loading to customers transport plus 12 months warranty if installed commissioned by VTT. Machinery Safety – Declaration of Conformity according to which country the machine is installed ……………………………………..………………………………………………………..£475,000.oo

Additions for guarding – option i) £40,000.  option ii) £65,000

 

Transport, installation and commissioning

The method of transport will depend very much on the destination – 4 x 12m trailers or 40ft open top containers.

 

Installation onto a foundation prepared by others and commissioning can be budgeted at £40,000 plus travel and accommodation for 4 engineers
