A section of the control room in Unit Machine Shop.
The Churchill Link Line, on which nine machines linked by automatic conveyors of the latest design, carry out consecutive operations to produce completed final drive shafts.
The power-pack line, with operators working on the complete assembly of engine, gearbox, final drive and rear suspension, prior to its journey by overhead conveyor to the Car Assembly Block.
The first of the two main blocks of the factory contains the Machine and Unit Assembly, with other necessary services to production such as:
Here are made the components for the power pack, transmission, and front and rear suspensions, which are subsequently built into the car in the adjoining block.
Brake drums for the Imp are machined on the Ryder rotary automatic machine.
In the Machine Shop are the most up-to-date precision machine tools, incorporating many 'transfer lines' where machines are linked automatically and components are passed from one operation to another without being touched by hand. Control of many operations is by electronic equipment.
In the section concerned with the machining of the major front and rear suspension components, the Archdale Transfer Machine automatically passes a pair of rear suspension arms through 11 simultaneous operations.
Nearby, the Ryder No. 10 Automatic 12 Station Machine completely processes brake drums at the rate of a pair every minute.
In the Transmission Machining Area stands the line of six Alfing Kessler Transfer Machines, processing housings for the transmission gears of the car. There is the 'soft' section - where the un-hardened gears receive their initial cuttings operations - followed by the Heat Treatment, where semi-cut gears are hardened before going to the 'hard' section for their final cutting operation. Among the machines are some of the latest types to be employed in the motor industry, and the Gleason Hypoid Gear and Pinion machining line is just one example of modern equipment. This cuts the crown wheel and pinion gears for the differential final drive unit.
The gearbox and transmission assembly line is in the form of a 'carousel' conveyor track. On completion and test, the transmission assemblies are passed to the adjacent track for assembly to the engine and rear suspension. From here, the complete unit - comprising engine, gearbox, final drive and rear suspension - is passed by overhead conveyor to the Car Assembly Block.
A section of the Heat Treatment - or Metal Hardening Plant - which embodies the very latest processes.
The entire production side of the factory is planned to co-ordinate the quantity of unit production by individual sections to obtain the utmost continuity of working, and consequently maximum production. This unit/time factor is on average, one item every minute. The two major blocks each cover an area of 324,000 sq. ft., with space to effect expansion with the minimu movement of existing plant and machinery.
The Archdale Transfer machine, where rear suspension arms are automatically passed through each of the 11 machining stations.
