High-Precision Roll & Surface Grinding

On-Site Precision Grinding for Rolls, Cylinders, and Flat Surfaces

Benroc Engineering offers high-precision in-situ grinding services, including roll grinding, cylindrical grinding, orbital grinding and superfinishing, and surface grinding. Our bespoke portable grinding machines are designed for a variety of applications, delivering workshop-quality finishes directly on-site without the need to transport heavy components.

Whether restoring flat surfaces or cylindrical rolls our precision grinding capabilities ensure components meet exact tolerances and perform reliably in demanding industrial environments.

Technical Overview & Benefits

Our precision grinding services are versatile and tailored for heavy engineering applications:

.
In-Situ Surface Grinding:

• Produces precise flat surfaces with excellent finishes.
• Capable of achieving tolerances within 0.01mm (depending on size, material, and rigidity)

Cylindrical Grinding:

• Produces round, parallel surfaces where the component can rotate.
• Ideal for shafts, rollers, and cylindrical components

Orbital Grinding & Superfinishing:

• Produces round, parallel surfaces where rotation is not possible.
• Ensures smooth finishes and precise profiles even on fixed components.

Roll Grinding:

• Restores rollers and cylindrical components to correct diameter and roundness.
• Essential for press rolls, lead mill rollers, paper mill rollers, and other rotating machinery

Key Benefits:

• On-site precision grinding reduces downtime and eliminates transport costs.
• Delivers workshop-quality tolerances and surface finishes.
• Suitable for large, heavy, or awkward components
• Extends component life and enhances operational performance.
