Bronze Bushings : Manufacturing Process
Manufacturing Process Foundry:
- Continuous Casting (10 dia to 125 dia)
- Centrifugal Casting (125 dia to 500 dia)
- Gravity Die Casting/Permanent Mould- Short freezing range alloys. Cost effective for bushes with flanges.
- Shell Moulding (10 dia to 175 dia). Cost effective for medium volume flange bushes in long freezing range alloys.
The process of manufacture is carefully selected by the engineering team depending on cost, quality and engineering factors.
Manufacturing Process Machine Shop:
- Turning (Single Spindle Automats, Chuckmatics, CNC Turning Centers, Hardinge Finishing Machines.)
- Oil Groove on SPMs (Single Loop, Figure Eight, Straight and Circular, Double Loop, Double Fig Eight, Half Fig Eight, Straight, Circular)
- Milling (Face groves)
- Drilling (Face, body and oil groove drills)
- Broaching
- Centerless Grinding
- Burnishing
The process of manufacture is monitored for capability of CpK higher than 1.33 for Critical to Quality characteristics that are either customer designated or internally determined.
