Automated cell delivered for
Charpy test pieces
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.
The final solution delivered by HNC Partners, Agemaspark of Doncaster, was a totally enclosed, fully automated cell utilising three Hardinge Quest model 6/42 CNC lathes fitted with GE Fanuc 18i CNC controls and Eppinger Preciflex driven tool turrets and ‘C’ axis spindle control, plus pick-and-place robots, auto conveyors along with laser component recognition and measurement.
Robot
Interface - GKN Driveline
Working in partnership with Agemaspark of Doncaster. The team of HNC
engineers provided the interface & progamming between an ABB robot
and a Hardinge Machining Centre fitted with a Fanuc 0i control system.
The machine/robot cell was developed for the production of complex automotive
drive shafts for GKN Driveline’s Birmingham manufacturing facility
and was integrated into a larger fully automated system. With HNC’s
involvement, loading and handling time was reduced almost ten fold to
15 seconds !

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 fitted a complete GE Fanuc 18i-TB CNC control system, with new digital
servo motors and drives. HNC originally fought off stiff competition
to win the order by having the necessary skills, expertise and facilities
to complete the job to a high standard within a competitive budget.
HNC rebuild – Cummins Ltd
The eight FMT 2500 horizontal machining centres installed at Cummins
Engines of Daventry some 20 years ago have consistently achieved the
rigorous productivity schedules asked of them operating continuously
24 hours a day with exceptional reliability. When more output was required
from the machines, Adam Dawson, Cummins maintenance manager was tasked
with enhancing their performance.
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
is paramount and that is what we get from HNC!” -Adam Dawson Cummin Engineering
BAE Systems – Warton, Lancashire.
Machine: C.B. Ferrari S66 5-axis milling machine.
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.
Machine: Cincinnati Hypowermatic milling machine.
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.
