Centreless Bar Precision Grinding
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.
