We can cut blanks to length with a diameter anywhere between 12mm & 750mm. With 6 band saws and one high speed circular saw, we are happy to handle both a one-off “special” and multiple cuts with volume demand in any stainless grade. We are also happy to work with your own free issue stock. The smallest length possible is 10mm.
With our annually renewed ISO 9001:2015 Quality Management System Accreditation, you are assured of quality processes.
We have 2 straightening presses, able to handle bespoke tolerances, operating quickly, precisely and reliably. A typical tolerance on the straightness is 1mm per 1,000mm.

Experience: We have over 25 years of grinding experience to call on and have a dedicated team of skilful grinding operatives.
Capability: We offer precision grinding of long bar from 2mm diameter right up to 240mm diameter, in lengths from 2,500 mm to 12,000m. We can supply to a tolerance of 0.0005″ and a surface finish of Ra 35 or better, depending on diameter and grade. Our Precision Grinding facility consists of 5 Lidkoping Centreless Grinding machines with automatic bar feeders, 2 straightening presses and 1 polishing line, giving us the ability to handle volume orders to tight tolerances and lead times. To ensure consistent surface finish we have invested in new and improved surface roughness measurement equipment, which measures the surface finish whilst the bar is in production. A typical tolerance on the surface finish is 32 CLA maximum. The results are then saved electronically to allow reporting within the certification package to the customer.
Quality: Over the last few years we have implemented a continual improvement program with procedures that are assessed and have met ISO 9001:2008 Quality requirements, ensuring your bars are processed on time to your requirements. These are reviewed annually to ensure we continue to offer our customers excellent quality.
Applications: Centreless ground bars are well suited for applications such as marine drive shafts and pump shafts.
Bird Stainless can offer to grind your free issue material stainless steels from 2mm diameter to 240mm diameter, in lengths from 2500mm to 12000mm.
We have 1 polishing line, giving us the capability to polish bars after centreless grinding.
A longstanding relationship with a reliable external supplier enables us to provide turning and boring processes when required.
In addition, we can offer third party testing and inspection with your required testing house such as DNV.GL (Det Norske Veritas (Norway) / Germanischer Lloyd (Germany), ABS (American Bureau of Shipping), BV (Bureau Veritas), RINA (Royal Institute of Naval Architects), and many more.
We wrap our finished products in Netlon sleeve, a thermoplastic mesh, to ensure maximum protection. If necessary, we will also box, for added protection. We then ship our steel to worldwide destinations by road, sea or air freight.
