With bid submissions closing on 08 October 2026 at 03:00 PM IST, this procurement represents a high-margin, prestigious contracting opportunity for indigenous machine tool manufacturers, authorized precision tooling distributors, and mechanical engineering MSMEs. Modern tool-and-die manufacturing, aerospace component machining, precision press stamping dies, and technical vocational training require sub-micron precision CNC wire EDM tools capable of cutting hardened alloy steels, titanium, and tungsten carbide with mirror-like surface finishes. Sized at an estimated value of INR 42 Lakh, the project avoids the crushing balance sheet requirements of multi-machine industrial mega-tenders. In accordance with Central Public Procurement Policy guidelines and GeM General Terms and Conditions (GTC), registered Micro and Small Enterprises (MSEs) holding valid Udyam Registration as machine tool manufacturers enjoy a 100% statutory exemption from depositing the INR 84,000 Earnest Money Deposit (EMD).

The procuring establishment serves as a national center of excellence for precision mold manufacturing, press tool fabrication, and technical engineering training. The facility manufactures high-precision injection molds, extrusion dies, and aerospace prototypes for defense research labs and private engineering industries.

The technical evaluation board comprises senior tool design directors, master manufacturing engineers, and central purchase officers who place absolute priority on machine positioning accuracy (sub-3 micron), cutting speed stability, automated wire threading reliability, energy-efficient pulse generator design, and prompt technical service within the industrial corridor.

The turnkey supplier will deliver, unload, assemble, precision level, calibrate, and commission the complete CNC Wire Cut EDM platform comprising the following six modules:

A. Machine Tool Bed & Mechanical Axis Structure

Heavy-duty cast iron bed (Meehanite grade or equivalent) stress-relieved to prevent thermal deformation, with linear motion guideways and precision ground ball screws on all axes.

Axis Travel: Minimum X-axis travel 400 mm, Y-axis travel 300 mm, Z-axis travel 250 mm, and U/V axis travel ±30 mm for precision taper cutting up to ±15° over 100 mm workpiece height.

Maximum Workpiece Dimensions: Accommodating parts up to 750 mm x 550 mm x 240 mm, with maximum table load capacity of at least 500 kg.

B. High-Precision Positioning & Cutting Performance

Resolution and Accuracy: Positioning accuracy of ≤0.003 mm (3 microns) and repeatability of ≤0.002 mm (2 microns) across full travel, verified via laser interferometer testing.

Cutting Performance: Maximum cutting speed of ≥160 mm²/min on high-carbon high-chromium (HCHCr) steel using standard 0.25 mm brass wire.

Best Surface Finish: Achieving surface roughness of Ra ≤ 0.8 µm (with multi-pass trim cutting achieving Ra ≤ 0.4 µm).

C. Advanced CNC Controller & Automated Wire Management

Industrial PC-based CNC controller with minimum 15-inch color LCD touchscreen, multi-axis interpolation, USB/Ethernet connectivity, and intuitive conversational G/M-code programming.

Automatic Wire Threading (AWT): Reliable automated wire threading through workpiece start holes down to 0.5 mm diameter, with automated wire chop/disposal bin.

Wire Tension Control: Digital closed
