Capabilities

Milling

3-Axis CNC Milling

Close-tolerance milling of aluminum, steel, and stainless — brackets, plates, housings, and custom mechanical components.

Prototype

Prototyping & First Articles

From a print or a model to a proven first part, with the inspection record to back it up before a run starts.

Production

Low-Volume Runs

Short and repeat production where consistency part-to-part matters more than raw volume.

One-Off

Single Parts & Repairs

Replacement components and one-off pieces machined to a drawing or reverse-engineered from a sample.

Materials

Metals & Traceability

Aluminum and steel alloys with material certifications retained, so every part can be traced back to its stock.

Inspection

Dimensional Inspection

Parts checked against the print and documented — measurements recorded, not assumed.

Capacity is growing. Have a part that needs more machine than one mill? Ask — we will tell you honestly whether it fits.

How We Work

A new shop, run to a standard older than the shop. Sahni Precision Systems is a Texas company formed in 2026 and owner-operated. We build the quality record — inspection, calibration, and material traceability — from part one, so it is there when a customer asks for it.

→Machined to the print.You give us the drawing or model and the tolerances; we hold them or we tell you before we cut.
→Traceable materials.Material certs are kept and tied to your parts — full traceability from stock to shipped part.
→Documented inspection.Critical dimensions are measured and recorded, not eyeballed.
→Built for the defense path.Quality and export-control practices are being established toward the standards primes require.
