ES Precision Metals specializes in Precision Grinding services that deliver extremely tight tolerances, superior surface finishes, and repeatable dimensional accuracy. Our grinding expertise plays a critical role in enabling high-performance mechanical and instrumentation components.

What Is Precision Grinding?

Precision grinding is a finishing operation in which an abrasive wheel removes minute amounts of material to bring a component to exact dimensions and finishes. This process is used when very fine tolerances (often within a few millionths of an inch) and excellent surface finishes are required.

  • High-accuracy diameter control
  • Mirror or fine matte surface finishes
  • Minimal material removal for final sizing
  • Capable of complex geometries and high precision geometries

Our Capabilities & Techniques

We employ advanced grinders, specialized wheels, and experienced operators to meet precise specifications across a range of materials and part types.

  • ID, OD, surface, and cylindrical grinding as needed
  • Materials including stainless steels, tool steels, alloy steels, exotic alloys
  • Batch and prototype volumes
  • Complementary operations like straightening, chamfering, or polishing
  • Capability for special geometries (grooves, flats, shoulders) within grinding operations

We monitor wheel wear, cooling, and dynamics carefully to ensure stability, avoid thermal damage, and achieve consistency. Each part is inspected via coordinate measuring machines (CMM), roundness testers, and surface profilometry to assure compliance.

Industries & Applications

Parts requiring precision grinding often function in mission-critical systems, found in:

  • Aerospace & defense (e.g. shafts, pistons, probes)
  • Medical & surgical instruments
  • Optical, sensor, and metrology devices
  • Industrial automation & robotics
  • High-precision bearings, spindles, actuators
