It is widely used to finish parts that have been hardened by heat treatment, as traditional milling cutters struggle with materials harder than 50 HRC.<\/p>\n At Jucheng Precision, we operate automated Okamoto and Chevalier surface grinders equipped with fine-grit ceramic and diamond wheels. We specialize in finishing mold bases, stamping dies, and precision machine components to flatness tolerances within 0.005mm. Whether removing heat-treat distortion or achieving a sealing surface, our grinding department ensures the highest level of geometric accuracy.<\/p>","protected":false},"featured_media":419,"template":"","process_category":[40],"class_list":["post-418","process","type-process","status-publish","has-post-thumbnail","hentry","process_category-precision-grinding"],"_links":{"self":[{"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/process\/418","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/process"}],"about":[{"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/types\/process"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/media\/419"}],"wp:attachment":[{"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/media?parent=418"}],"wp:term":[{"taxonomy":"process_category","embeddable":true,"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/process_category?post=418"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n\n

\n \nMethode<\/th>\n Beschreibung<\/th>\n Hauptvorteile & Anwendungen<\/th>\n<\/tr>\n<\/thead>\n \n Horizontal Spindle (Reciprocating)<\/strong><\/td>\n The most common type. The wheel is on a horizontal axis, and the table moves back and forth. The wheel cuts on its periphery.<\/td>\n Vorteil:<\/strong> Highest precision, superior surface finish, excellent flatness.
\nAnw.:<\/strong> Precision tool making, mold plates, gauges.<\/td>\n<\/tr>\n\n Vertical Spindle (Blanchard)<\/strong><\/td>\n Also known as Rotary Surface Grinding. The wheel face grinds the part. Removes material much faster.<\/td>\n Vorteil:<\/strong> Rapid stock removal for large areas. Distinct “cross-hatch” pattern.
\nAnw.:<\/strong> Cleaning up large raw castings, flattening plates.<\/td>\n<\/tr>\n\n Creep Feed Grinding<\/strong><\/td>\n Taking a very deep cut at a very slow feed rate. Acts almost like milling but with a grinding wheel.<\/td>\n Vorteil:<\/strong> Can grind complex profiles (slots) in hardened material in one pass.
\nAnw.:<\/strong> Turbine blade roots, intricate tool slots.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nDesign Guidelines for Surface Grinding<\/h3>\n
\nSurface grinders primarily use magnetic chucks. Ferrous metals (Steel, Iron) are easiest to hold. Non-magnetic parts (Aluminum, Brass) require complex vacuum fixtures or blocking, which increases cost. Tipp:<\/strong> Design parts in steel if they require precision grinding.<\/p>\n
\nA grinding wheel cannot grind up against a 90-degree shoulder without leaving a radius. Tipp:<\/strong> Add an undercut or “grinding relief” groove in the corner so the wheel can pass through freely without hitting the wall.<\/p>\n
\nGrinding generates significant heat. Thin parts may warp due to thermal expansion or stress release. Tipp:<\/strong> Avoid extremely thin walls on parts that need to be ground flat.<\/p>\n
\nThe surface to be ground must be the highest point on the part. Any protruding pins, bosses, or features higher than the grind surface will prevent the wheel from passing.<\/p>\n<\/div>\nBranchenanwendungen<\/h3>\n
\nGrinding punch dies and stripper plates to exacting flatness to ensure the stamping tool cuts clean burr-free parts.<\/p>\n
\nMold bases and parting lines are surface ground to ensure a perfect seal, preventing plastic “flash” during injection.<\/p>\n
\nLinear guide ways and sliding blocks are ground to ensure smooth, low-friction motion and long service life.<\/p>\n
\nEngine cylinder heads and blocks are resurfaced (decked) to ensure a perfect seal with the head gasket.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
