Its 8 (4 + 4) patches cover Ra 0.025–0.2 µm (1–8 µin), roughness grades N1–N4. Series 100 plates are the heavy-duty design intended for workshop use, so the 118 can be kept beside the machine for comparing parts with known reference finishes. A lightweight Microsurf equivalent (318) is offered for office and design use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMachining method: Cylindrical Lapping + Superfinishing\u003c\/li\u003e\n\u003cli\u003eNumber of patches: 8 (4 + 4)\u003c\/li\u003e\n\u003cli\u003eRa 0.025–0.2 µm \/ 1–8 µin\u003c\/li\u003e\n\u003cli\u003eRoughness grades N1–N4\u003c\/li\u003e\n\u003cli\u003eHeavy-duty Series 100 construction for workshop use\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rubert","offers":[{"title":"Default Title","offer_id":67656279425137,"sku":"118","price":0.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0625\/3930\/0977\/files\/100-series-comparators_581db158-476f-4363-b8e9-45fcb0fb7566.jpg?v=1791811282","url":"https:\/\/www.generaltechshop.ae\/products\/rubert-118-series-100-roughness-comparator-lapping-superfinishing-ra-0-025-0-2-m-n1-n4-8-patches","provider":"General Tech Services LLC","version":"1.0","type":"link"}
