Description

Kalamazoo S4SWB 4 x 36 Inch Polishing Wet Sander

The Kalamazoo S4SWB is a 4 x 36 inch wet polishing sander is designed for precision metal sanding and polishing tasks. It features a ½ HP motor, a self-contained coolant system, and is commonly used for metallurgical polishing. This precision wet sander is known for its versatility and is utilized in various industries for tasks like sample preparation, weld evaluation, and inspecting grain size.

The Kalamazoo S4SWB 4″ × 36″ Wet Bench-Top Belt Sander is a reliable polishing sander built for labs and manufacturers that require clean, repeatable surface finishes before metallurgical inspection. It helps prepare metal samples quickly and consistently, making it easier to reveal grain structure, surface defects, and machining quality.
Whether preparing parts for inspecting sleeve bearing surfaces, inspecting industrial bolts, inspecting a worm gear after it’s been cut, or inspecting an axial bearing, the S4SWB delivers controlled material removal with reduced heat and debris—supporting accurate inspection results every time.
Key benefits for metallurgical inspection applications:
  • Produces smooth, uniform finishes that improve visibility during microscopic and visual inspection.
  • Wet sanding design helps control heat, protecting material structure and preventing surface distortion.
  • Compact bench-top footprint fits easily into metallurgical labs, QC rooms, and inspection stations.
  • Consistent belt tracking supports repeatable results across multiple samples and operators.
  • Ideal for preparing flat and contoured parts prior to sectioning, polishing, or final inspection.
  • Built for daily use in inspection-driven environments where accuracy and cleanliness matter.
  • Made in the USA.

The S4SWB 4″ x 36″ Wet Bench Top Belt Sander is the perfect polishing sander for companies that need to prepare metal parts for detailed quality checks. This machine helps you get smooth, clean surfaces on metal components so you can see any defects or problems clearly under a microscope.
Here’s how metallurgical labs and quality control teams use this equipment:
  • Inspecting sleeve bearing surfaces – Quickly polish bearing surfaces to check for wear patterns, scoring, or material defects that could cause equipment failure
  • Inspecting industrial bolts – Prepare bolt cross-sections to examine grain structure, hardness zones, and check for cracks or weak points in critical fasteners
  • Inspecting a worm gear after it’s been cut – Polish gear tooth profiles to verify proper hardening depth, detect surface defects, and ensure the gear meets quality standards
  • Inspecting an axial bearing – Create mirror-finish surfaces on bearing races and thrust washers to identify pitting, spalling, or metallurgical inconsistencies
The wet belt sanding process removes material quickly while keeping parts cool, which prevents damage to the metal’s structure. This means you get accurate inspection results without changing the properties of the parts you’re testing.
