It provides a maximum measuring range of 40 inches and a resolution of 0.0002 inches, making it suitable for applications where tight positional accuracy is required. The scale achieves an accuracy of 0.0002 inches and ships with a 13-foot cable for connection to a compatible DRO display unit. Machinists and CNC service technicians install this type of scale on lathes, milling machines, surface grinders, and similar equipment to enable precise axis position feedback during machining operations.\u003c\/p\u003e\n\u003cp\u003eThis linear scale is intended for installation on machine tool axes in industrial and shop environments. It fits residential and commercial machine shops where operators require reliable position readout on manual or retrofitted CNC equipment. The 40-inch measuring range accommodates larger axis travels common on full-size knee mills and mid-size lathes. The 13-foot cable provides adequate reach from the scale body to a remotely mounted DRO display without requiring extension cables in most standard machine configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e40-inch maximum measuring range for longer axis travel applications\u003c\/li\u003e\n \u003cli\u003e0.0002-inch resolution glass scale for precise positional feedback\u003c\/li\u003e\n \u003cli\u003e0.0002-inch accuracy rating suitable for precision machining work\u003c\/li\u003e\n \u003cli\u003e13-foot cable included for connection to DRO display unit\u003c\/li\u003e\n \u003cli\u003eGlass scale construction for stable, low-thermal-expansion measurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade linear scale for DRO systems on precision machine tools requiring a 40-inch travel glass scale with 0.0002-inch resolution.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or qualified equipment technician. Power down the DRO display unit and any associated machine controls before mounting or wiring the scale. The scale body and read head must be aligned carefully per manufacturer tolerances to ensure accurate position output. Follow applicable machine tool safety procedures and consult the DRO system documentation for proper cable termination and grounding requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eMaximum Measuring Range\u003c\/strong\u003e: 40 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCable Length\u003c\/strong\u003e: 13 feet\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eScale Type\u003c\/strong\u003e: Glass\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11 pounds\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: DRO Linear Scales\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACU-RITE\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 558115-40\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACURITE","offers":[{"title":"Default Title","offer_id":68308059652402,"sku":"558115-40","price":1476.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8eb4018f02ebcaf4fe0c1d58904dc313_a77087d5-fcb6-47c6-81a4-82bd54c03e4f.jpg?v=1793772857","url":"https:\/\/voomisupply.com\/products\/acu-rite-558115-40-dro-linear-scale-40-inch-glass-scale","provider":"Voomi Supply","version":"1.0","type":"link"}
