At Corus’ Scunthorpe steelworks, a test piece is taken from each production batch with results forwarded to customers; some 450 test pieces need to be produced each day. The requirement was to design, develop and manufacture an automated process to produce “Charpy Impact Test” pieces, measuring either 5, 7.5 or 10mm wide x 10mm high and 55mm long with a centrally machined vee 2mm deep to an overall maximum tolerance of 60 microns within a time of 9 minutes for a set of 3 test pieces.
The HNC solution involves raw, sawn blanks being loaded into a chute, retrieving data via their bar codes from Corus’s existing VAX system and automatically, by way of laser technology being checked for overall size. If results are OK it then progresses by way of pick and place robot and lightweight conveyor systems for milling the 4 sides and two ends on - a CNC Lathe. Prior to this machining the CNC lathe also receiveds data from the VAX giving test piece size and hardness.

HNC refurbish - Giddings and Lewis VTL
HNC have completed the electrical and mechanical refurbishment of
a Giddings and Lewis VTL with a 60 inch diameter table.
HNC rebuild – Cummins Ltd
Halifax Numerical Controls (HNC) were recommended by several companies as being the right company for the job. Mike and Tim were able to demonstrate to Siemens and Cummins the quality of their rebuilds and service and the order for the first machine was placed in March 2005.
The rebuild of the first machine was completed on time and passed the tough Cummins acceptance tests with few problems. Since then, HNC have rebuilt three of the FMT machines and managed to squeeze in a DeVlieg model 5K Jigmil rebuild for Cummins as well.
Adam Dawson and colleagues at Cummins speak highly of HNC with their “no nonsense” approach to business. Nothing appears too much trouble to them.
Above all the quality and reliability
of the finished product
BAE Systems – Warton, Lancashire.
HNC retrofitted a Ferrari S66 5-axis milling machine with a state of the art Heidenhain iTNC 530 CNC system interfacing with Siemens digital drives and motors. This gave the machine a new lease of life, ensuring reliability in the years to come manufacturing component parts for the Harrier jet. HNC did the contract through Wyko Industrial Services who have offices on site at BAE systems and whom we have a close working relationship.
De Smet Rosedowns Ltd.
HNC re-engineered a Cincinnati Hypowermatic milling machine for De
Smet Rosedowns of Hull. This machine is to mill component parts for
the company’s range of vegetable oil extracting machines. We took
an old machine fitted with a hydraulic copying attachment, totally re-engineered
the machine fitting a GE Fanuc two axis Power Mate with new digital
servo drives. This makes the machine far more flexible and reliable
than before allowing the operator to change the profile of the component
by selecting different programs. The machine was fitted with new guarding
and safety interlock system incorporating the magnetic chuck.
