Grinding & Blasting
Pitrukrupa Engineering offers professional Grinding & Blasting Services for precision CNC machined, fabricated, and engineering components. Our processes improve surface finish, remove burrs and imperfections, prepare components for coating or plating, and ensure consistent dimensional accuracy. These services help achieve a smooth, clean, and uniform surface while enhancing the overall quality and appearance of metal parts.
We provide high-quality finishing solutions for components manufactured from Aluminium, Stainless Steel (SS), Mild Steel (MS), Brass, Copper, Tool Steel, Alloy Steel, and other engineering metals.
Our Grinding & Blasting Services
- Glass Bead Blasting: Glass bead blasting produces a clean, smooth, and satin surface finish while removing oxidation, machining marks, and contaminants. We offer finishes ranging from 100–50 micron, making components suitable for decorative and industrial applications.
- Deburring & Edge Finishing: Precision deburring removes sharp edges and burrs created during machining, improving safety, assembly performance, and component reliability.
- Surface Cleaning: Industrial surface cleaning eliminates oil, rust, scale, dust, and machining residues before further surface treatment, coating, or plating.
- Polishing & Buffing: Our polishing and buffing services enhance surface smoothness, improve appearance, and prepare components requiring decorative or mirror-like finishes.

Painting
Pitrukrupa engineering most commonly uses the RAL classic system to match custom blended paints for any color code or paint swatch. For two-color or multi-color painting, we make proper masks and use tape to keep the mask lines tight and clean. With masking, we can divide elements of your monolithic prototype into several finishes for a more complicated appearance looks like 2k and 3k molding.
Laser Etching & Printing
Pitrukrupa Finished parts can offer with laser marking & engraving on metal items with quality work. CNC machined parts can be personalized & branded with logo marking & engraving as per customer requirements.
