What We Offer
CNC Machining
Working from drawings, CAD or DXF files, B&B Precision provides CNC machining for small to medium-sized components. We have extensive experience manufacturing valve components and can support projects requiring CNC milling, CNC turning, surface grinding, internal grinding, cylindrical grinding, hard part turning, HVOF coating, flame spray coating, lapping and EDM wire erosion.
Materials
As a sub-contract manufacturer, we work with a wide variety of materials including cast steels, cast iron and cast magnesium, often used in valve components. We also machine hard and exotic materials such as Inconel, Monel and Kovar. Whether working from castings, free issue material or material sourced by us, we provide full material traceability.
Metal Finishing
B&B are also able to offer Thermal Spray Coating of Valve components. These coatings are most often used in extreme wear and corrosive environments with high temperatures. Common coating materials include Stellite 6 and Tungsten Carbide. We also have trusted partners for anodising, plating or painting to finish.
Repair and Refurbishments
Thermal spraying is an additive process that can be used to build up worn areas before components are ground back to tolerance. HVOF coatings can be customised to suit the base material and performance requirements of the component, offering strong adhesion and helping extend service life. Repairing worn parts is often significantly cheaper than replacing them.
