CMM Cuts Inspection Time

In 2021, cylindrical grinding machine builder Grindex d.o.o. in Kikinda, Serbia, installed its first coordinate measuring machine (CMM), an Altera M 20.12.10 manufactured in the U.K. by Castle Donington-based LK Metrology Ltd. (LK Metrology Inc. is in New Hudson, Michigan.) Grindex uses the ex-demo CMM daily to check tolerances mainly tighter than ±0.05 mm (±0.002″). When the company was looking to invest, a CMM was chosen instead of an optical scanning metrology solution, which was not regarded as being sufficiently accurate. Having a nominal inspection volume of 2,000 mm × 1,200 mm × 1,000 mm (78.7″ × 47.2″ × 39.4″), the CMM is installed in a dedicated inspection room. The machine was supplied with a touch-trigger probe for general inspection and complex stylus builds. It also features an analog scanning probe for rapid capture of dimensional and surface data from:

• • iron, steel and aluminium castings,
• • engine housings,
• • machined components,
• • molded parts,
• • fabrications, and
• • additively manufactured components and assemblies.

Training and initial programming assistance formed part of the LK package, along with ongoing consultancy. The LK machine was selected in preference to other brands of CMMs based on recommendations from other manufacturers in nearby Serbian cities. The equipment has considerably upgraded the metrology capability of Grindex, whose quality control toolbox was previ-
