Precision Grinding Services
Flat, Round & Repeatable Finishes
Applications
- Anchor bolts, rods, and studs
- Base plates and structural assemblies
- Machined shafts, bushings, and spacers
- Fabricated weldments requiring flat mating surfaces
- OEM components and custom hardware
Alexander Screw Products provides Blanchard and Centerless grinding services for custom machined parts, anchor bolts, plates, and assemblies. Our grinding departments handle both production and precision finishing with the same focus on tight tolerances, consistency, and ISO-certified quality.
Capabilities & Equipment
Blanchard Grinding (Rotary Surface Grinding)
Ideal for large plates, base components, and assemblies requiring flatness and parallelism across broad surfaces. Our Blanchard grinders handle workpieces up to 40″ in diameter, producing clean, cross-hatched finishes perfect for welded or bolted interfaces.
Centerless Grinding
For shafts, rods, studs, and anchor bolts where diameter accuracy and smooth surface finish are critical. We maintain diameter control within ±0.0002″ and finishes to 16 micro-inch Ra or better on runs from one piece to thousands.
Cylindrical & Surface Grinding
Supporting precision fits, bearing surfaces, and post-machining finishing on custom parts.
Material Capability: Carbon, stainless, alloy steels, and aluminum
- Work Size Range: Diameters up to 4″; lengths to 48″

Why Blanchard & Centerless Grinding Matters
Both processes complement our machining and fabrication services:
- Blanchard Grinding ensures flat, stable mounting surfaces for base plates, templates, and structural parts.
- Centerless Grinding delivers concentricity and surface precision for threaded rods, studs, and anchor bolts.
Together, they create repeatable fits and assembly alignment across our product lines.
Quality & Inspection
Every part is processed under ISO 9001:2015 controls with in-process checks and final inspection. We verify flatness, thickness, and roundness using precision micrometers, profilometers, and surface plates to ensure each component meets drawing specs.
