CASE HISTORIES -
1990 British Steel, Dalzell Works, Motherwell: Fully automatic Johannsen abrasive plate grinding machine for removing spot faults and for grinding and blending the entire surface. Very similar to the machine at British Steel in Sheffield but slightly smaller. Abrasive belts were 300mm wide and over 20m long. The machine replaced more than five “barrow buffing machines”, ie manually operated floor grinders.
1990 Edbro, Bolton: Multihead abrasive belt polishing machine. With automatic load and unload facility for polishing of hydraulic cylinders for tipper lorries. After extensive tests had been carried out this was the first time that diamond abrasive belts were used on a production machine.
1991 Sillavan, Bury: Automatic Johannsen abrasive belt grinding machine for grinding and polishing of plate for the nuclear industry. Plates had to be finished to a very high standard which could only be achieved with the Johannsen. Abrasive belts were 300mm wide and approx. 15m long This machine was of the same design as the machines
at British Steel in Sheffield and Motherwell, just smaller.
1993 EMA, Turbine blade factory in Naples, Italy. In conjunction with Rolls Royce: Abrasive belt grinding, and polishing machines and variable speed polishing machines to equip an entire new finishing department.
All machines were designed for manual operation and modified to comply with Rolls Royce’s Abrasive Test Centre.
1994 Doncasters Deritend, Droitwich: 2 off Reichmann abrasive belt power grinders with horizontal reciprocating table and incremental feed. For grinding feeders off large turbine blades. Fully automated and programmable.
1995 Rolls Royce, Derby: 3 off Timesavers abrasive belt power grinders for grinding large feeders on turbine blades.2 off machines with horizontal tables, 1 off machine with vertical table, All with 75 HP abrasive belt drive
motors.
1995 William Lee, Sheffield: A fully automated REMA grinding wheel machine for deflashing the OD of round castings from 150mm to 240mm dia. With 37 KW main motor.
1995 -
Precision, Bury Electroplating: After the 3M Company had developed Microfinishing Film, Surtech were the first and only Company to promote this revolutionary new system together with microfinishing machines from the American GEM Company. For the first time it was possible to produce surfaces from approx. 60 CLA to below 1CLA on rolls of all sorts of materials. More than 25 machines were sold before other manufacturers appeared on the market with dumping prices.
1995 Rolls Royce, East Kilbride: Half a dozen specially designed abrasive belt machines for grinding and finishing of refurbished turbine blades. All with variable speed controls and the facility to change quickly from 25mm dia. to 200mm dia. contact wheels. Because the abrasive belts were driven from the rear, independently from the
contact wheels the abrasive belt cutting speed remained the same no matter what size contact wheel was used.
The machines were height adjustable. Operators sat down.
1995 Centaur, Sheffield: 1 off Reichmann abrasive belt power grinder with rise and fall table. For grinding feeders off turbine wheels. With robot loading and unloading and vision control
check.
1995 Doncasters Deritend, Droitwich: 1 off Reichmann abrasive belt power grinder with vertical table and incremental feed. For grinding feeders off turbine blades.
1996 British Aerospace Aerostructures Ltd, Filton, Bristol: 2 off Timesavers abrasive disc machines, model CS 360 and model CS 180 for deburring clad aluminium sheet after punching on Trumph machine. Wet operation including drying unit.
1996 Howmet, Exeter: 2 off Reichmann abrasive belt power grinders with vertical table and incremental feed.
1997 British Aerospace Defence, Brough: 1 off Timesavers abrasive disc machine, model CS 360 for deburring clad aluminium sheet. Wet operation including drying unit.
1997 Tantofex, East Grinstead: 1 off MAPOS robot cell for linishing and polishing brass taps.
1997 Thessco, Sheffield: 2 off fully automated polishing machines for cutlery and flatware. The first Sheffield Company to invest in new technology for a long time.
1998 Armitage Shanks, Wolverhampton: 3 off MAPOS robot cells for linishing and polishing brass taps.
1998 Swann Morton, Sheffield: Automatic coil polishing and finishing line. For stainless steel coil used in the manufacture of surgical knife blades.
1998 Howmet, Exeter: A horizontal, reciprocating abrasive belt milling machine for grinding feeders on large turbine blades. With incremental feed. This was and probably still is the largest and most powerful abrasive belt rapid grinding machine in the UK.
1999 Carrs, Sheffield: 2 off fully automated HAUSCHILD cutlery and flatware polishing machines. Together with the machines at Thessco the most modern polishing machines in the Sheffield cutlery trade.
