COMEC RP330-Z: the solution for specimen

RP330-Z – Concrete Sample Surfacing (Grinding) Machine

The RP330-Z is specifically designed for grinding cylindrical and cubic specimens of concrete blocks, bricks, rocks, and natural stones.

It is a crucial step in the testing cycle, ensuring the maximum accuracy and surface flatness of the sample—an essential requirement for obtaining valid compression test results that comply with international standards.
Why the RP330-Z is the Right Choice for Your Laboratory:
  • High capacity: The samples are fixed on the worktable by means special clamps wich allow the RP330-Z to grind many samples simultaneously.
  • Assured regulatory compliance: Achieve the necessary specimen surface flatness to meet international standards.
  • Heavy-Duty cast iron structure: The cast iron frame is specifically designed to withstand intensive grinding cycles, maintaining stability and precision over time.

  • High Precision and Repeatability: Essential for compliance and result reproducibility, thanks to the high-efficiency grinding system.

  • Easy to operate, low maintenance: Optimizes workflow and reduces laboratory downtime.

  • Ideal for: Accredited testing laboratories, material control centers, and construction companies focused on certified quality.

Thanks to its reliability and performance, the RP330-Z is the definitive solution for professionals who require consistent and high-quality results for compression tests.
