Fitter Marking-Out Plate

The fitter marking-out plate is a precision-ground cast iron surface designed for manual scribing, layout work, inspection, and part positioning in mechanical workshops. It provides a stable and flat reference base for skilled fitters during metalworking, measurement, and fabrication tasks.

Material
Made from high-grade HT200–300 cast iron, the plate undergoes heat treatment, natural aging, or artificial annealing to eliminate internal stress and ensure long-term dimensional stability.

Key Features

• High Surface Flatness
  Manufactured to conform with DIN 876 or GB/T22095-2008 standards. Available in Grade 0, 1, or 2 flatness tolerances.

• Hand-Scraped or Machined Surface
  The surface can be manually scraped for higher precision or finely machined, based on customer requirements.

• Reinforced Rib Structure
  Designed with ribbed reinforcements underneath to resist deformation and vibration during use.

• Anti-Rust Treatment
  Treated with protective coating to prevent rust during storage and use.

Applications

• Manual scribing and layout marking of mechanical components

• Workpiece positioning and measurement

• Tool and die assembly

• Visual inspection and testing

• Use in fitter’s benches, repair shops, and tool rooms

Specifications

• Flatness Grades: Grade 0 (high precision), Grade 1, Grade 2

• Available Sizes: Customizable from 100×100 mm up to several meters in length and width

• Surface Finish: Scraped, ground, or milled

• Optional Add-ons: Leveling pads, lifting holes, or cast-in handles

Benefits

• Stable and reliable reference surface

• Enhances scribing precision and part alignment

• Durable under repetitive use in tough working environments

• Long service life with minimal maintenance

Conclusion
The cast iron fitter marking-out plate is an indispensable tool in mechanical fabrication and inspection tasks. Its high stability, precision, and rugged design make it a core component in tool rooms and manufacturing facilities worldwide.
