Centerless Grinding
Centerless Grinding Services: Precision Manufacturing Excellence
When your precision machined components demand exceptional accuracy and superior surface finishes, Swissturn/USA’s centerless grinding services deliver the reliability and expertise you need. With over 40 years of in-house centerless grinding capability, we’ve established ourselves as a trusted partner for manufacturers requiring the highest standards of dimensional precision and surface quality.
In 2023, we significantly enhanced our centerless grinding capacity by acquiring Malden Centerless Grinding Company, integrating their specialized equipment and experienced personnel into our Oxford, Massachusetts facility. This strategic expansion brought our centerless grinding capabilities to a level rarely found in CNC Swiss screw machine contract manufacturing, positioning us as your comprehensive precision manufacturing partner.
Advanced CNC Centerless Grinding Technology
Our precision centerless grinding operations utilize both Cincinnati and Royal Master centerless grinders, capable of processing bar stock up to 1″ in diameter and finished components up to 2″ in diameter. This advanced equipment enables us to achieve extraordinarily tight tolerances and exceptional surface finishes that meet the most demanding specifications across aerospace, medical, defense, and industrial applications.
The fundamental advantage of centerless grinding lies in its ability to remove material from cylindrical parts without requiring centers or spindles. This highly efficient process produces extremely precise diameters and superior finishes by rotating workpieces between two wheels – the abrasive grinding wheel and the regulating wheel – supported by a work rest system.
Comprehensive CNC Grinding Services
Bar Stock Preparation
Our cnc grinding services excel in preparing raw materials for Swiss screw machine production. Bar stock that arrives from mills with diameter variations up to .005″ can be centerless ground to achieve .0003″ total diameter tolerance. This critical preparation step utilizes a thru-feed process, continuously feeding bar stock between grinding wheels to reduce diameter variations and improve surface finish – essential for seamless operation in our CNC Swiss screw machines.
Precision Component Finishing
Post-machining and post-heat treatment centerless grinding represents another core capability. We routinely process precision machined components, grinding finish diameters to extremely close tolerances while achieving superior surface finishes. This secondary operation proves invaluable for components requiring specific dimensional accuracy or enhanced surface characteristics.
