Product Details Supplier Info More products

Ward CNC has supplied a remanufactured 1,500mm-diameter-table Webster and Bennett Series S CNC vertical boring and turning machine to AJT Engineering, for orders from North Sea oil and gas customers.

The fully remanufactured vertical boring and turning machine was supplied through the Ward CNC Retrofit machine tool rebuild activity.

The ram-type machine joins a portfolio of other large-capacity machines supplied by Ward CNC, including a SMTC FBC-160R horizontal CNC floor-type borer, at AJT’s principal facility in Aberdeen, and is helping reduce project completion schedules.

AJT’s Aberdeen operation undertakes a wide range of activities, including dis-assembly; inspection (incorporating full NDT); manual and CNC machining; fabrication; welding, including weld cladding; furnace heat treatment; and assembly and pressure testing up to 22,500psi.

AJT also offers a cold extrusion service for the production of multiple outlet headers, as well as further service offerings through its British Heat Treatments and British Metal Treatments divisions in East Kilbride and Port Glasgow, respectively.

The repair and refurbishment of blow-out preventers and their constituent components form a considerable proportion of the Aberdeen business and with such units, when fully assembled, weighing in excess of 30 tonnes, the appropriate equipment is maintained for pre-weld preparation and final machining, following weld reclamation of the major components.

According to AJT, a growing order book meant the company had to urgently rebuild VTL.

For this purpose Ward CNC provided the Series S VTL.

Supplied complete with automatic toolchanger and new Fanuc Oi-TB CNC, the machine has 1,600mm under the crossrail and this accommodates around 75 per cent of AJT’s refurbishment project and new manufacturing workloads.

AJT has secured machines from Walter in the past, including several large-capacity units such as the SMTC travelling column and horizontal floor borer.

This has X and Y axes traverses of 4,000 by 2,500mm, respectively, a 4,000 by 4,000mm floorplate, and a 1,400 by 2,000mm CNC rotary table with 2,000mm travel.

The machine features two custom-made right-angle heads for machining internal cavities, as well as through-spindle coolant and Heidenhain iTNC-530M CNC.
