In a world where there are many options when it comes to choosing your precision grinding partner, it can seem challenging to pick the right one. Fortunately, there are several key differentiators that set Boston Centerless apart from other precision grinding companies. Visit our website to learn more about why our customers choose us  for precision grinding.

Demonstrated Quality and Reliability

At Boston Centerless, we ensure that every product we deliver meets or exceeds your requirements, giving you the peace of mind that your bar materials are manufactured with the highest standards. Companies that build their operations around precision ground bar must partner with a shop that delivers incredible consistency and reliability with no quality break-throughs. To maintain an outstanding level of quality, our team completes multiple measurements and quality checks in-house, resolving any issues that are identified before the precision ground bar leaves our shop. Our team is proud to report we have a Total Quality Assurance (TQA) of +99.5%, meaning our precision ground bar meets the necessary specifications and requirements with no quality issues at an exceptional rate. The team at Boston Centerless is also proud to report an on-time delivery 98% of the time. This level of quality assurance and reliability is something that distinguishes Boston Centerless from other suppliers.

Certifications are also an important aspect of quality, providing customers with the assurance that products meet the necessary standards and will be reliably manufactured and consistently provide the same level of performance. At Boston Centerless, our certifications include: ISO 9001, AS9100, ISO 13485, Nadcap Accredited, ITAR registered, and ASNT Level III certified. Achieving product certifications requires specific know-how and processes as well as personnel with the right skills and expertise. Certifications are just one of the reasons why customers choose Boston Centerless as their precision grinding partner.

Unmatched Precision Grinding

We understand that in the world of manufacturing, precision is not just a requirement but a necessity - and that’s where we excel. Our precision grinding methods are able to achieve diameter tolerance of 0.000040" (40 millionths). Our team recognizes that dimensional aspects such as roundness and straightness can be as critical, if not more critical, than the diameter size and tolerance; thus, our precision grinding methods are also able to achieve roundness to 0.000020" (20 millionths) and surface finish to 2 Ra.

At Boston Centerless, our proprietary processes have been developed over the years, and methodically passed down to ensure that our reputation for being the most consistently superior producer of ground bar products and precision grinding services would remain intact as the company grew and expanded. You will experience the results of our highly skilled and experienced people built into every precision ground product you receive. Our extensive experience and relentless commitment to quality distinguish us from other precision grinding providers.
