CMM Fixtures

Scope and process

Engineering workflow for cmm fixtures 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

Low-mass build with minimal obstruction of probe access, often on a modular base plate. 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 on the drawing datums — not on convenient surfaces — so measurement reflects the design intent.

Choosing the right option

When requesting a proposal for cmm fixtures, 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 datum repeatability and that clamping does not deflect the part while it is measured. Dimensions are verified on CMM against the fixture drawing before despatch.

Commissioning and handover

Handed over with a repeatability study — the same part loaded and measured several times — so datum repeatability is proven, not asserted.

Export packing and lead time

Ships on its base plate with the datum scheme marked and the setup documented. 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

Locating pads and pins are the wear items; recheck datum repeatability at a fixed interval.
