Sinico machines benefit automotive volume production

1 min read

Hagon, a manufacturer of automotive shock absorbers, uses Sinico CNC machines for the simultaneous double-end multi-operation machining of cut-to-length solid bar and tube, with capacities from 5 to 120 mm diameter and 20 to 2,000 mm in length.

Sinico has been supplying machines to the UK for more than 20 years and is well established in the volume production of automotive components as can be seen at Hagon where typical machining times are: 7.6 seconds (400 parts/hour) for a shock absorber cylinder, produced from 6 m steel tube; 10.0 seconds (306 parts/hour) for a shock absorber rod, produced from 6 m full steel bar; and 56.0 seconds (57 parts/hour) for a shock absorber head, produced from 6 m full steel bar. Bar and tube in 4, 6 or 8 m lengths can be loaded into the magazine that feeds the material automatically into the first stage of precision cut-to-length by circular HSS or tungsten carbide blades. The cut piece is transferred automatically by a high-speed rotary indexing turret to the simultaneous double-end machining operations that can range from a basic face and chamfer through to turn, bore, drill, tap and threading operations. Tooling for all operations is by the Sinico quick-change system and all CNC machine settings can be made through the Siemens touch screen.
