Drill Jigs

Scope and process

Engineering workflow for drill jigs at Dahegam, Gandhinagar, Gujarat, India: 3D CAD modeling of part workholding envelope → FEA clamping force and deflection analysis → CNC machining of hardened baseplates and locator nests → grinding of locating dowels and wear pads → laser CMM verification of critical datum points.

Materials we work with

Renewable hardened drill bushes in a plate, replaceable as they wear without scrapping the jig. Body material is chosen for the duty — tool steel where wear or heat is the issue, aluminium where the fixture must be lifted by hand.

Tooling support

Locates the part against fixed pads and positions hardened bushes over each hole.

Choosing the right option

When requesting a proposal for drill jigs, please provide component 3D CAD models (STEP/IGES), 2D part drawings indicating critical datums, machine table specifications (T-slot pitch, pallet size), and target cycle time. Quotes with 3D concept layouts are issued within 24 hours.

Quality checks and inspection

On a fixture the check that matters is bush bore wear, hole-to-hole centres, and position relative to the locating datums. Dimensions are verified on CMM against the fixture drawing before despatch.

Commissioning and handover

Handed over with a first-article set of holes drilled through the jig and measured against the drawing.

Export packing and lead time

Ships with the bush set fitted and a spare set of renewable bushes. HEMSUN is a DGFT IEC registered exporter (Government of India); commercial invoice, packing list and certificate of origin accompany international despatch.

Maintenance and spare parts

Drill bushes wear from the inside out; replace them on hole-position drift, not on visual inspection.
