The centerless grinding method is the most labor-saving solution in cylindrical grinding. However, if the angle of the guide wheel is off by even one degree, the accuracy of the workpiece will be completely ruined. Many factories often make the wrong choice between the through-type and the cut-in type when choosing between these two processing methods. As a result, the output of scrap products is directly doubled, and the extra money spent per year is hundreds of thousands.<\/p>\n

\n

Basic principles of centerless grinding<\/h2>\n<\/p>\n

Place the workpiece directly between the grinding wheel and the guide wheel without using a center for centering. The supporting plate below will hold the workpiece to bear the weight. Because the guide wheel will drive the workpiece to rotate together when it rotates, the entire process does not require clamping, resulting in minimal deformation.<\/p>\n

In China, mainstream models such as XW9240 and XW9320 can be used to process shaft parts with diameters ranging from \u03a68 mm to \u03a640 mm, and their processing rhythm can be maintained at a level of 3 pieces per minute. And in 2024, many product manufacturers specializing in shaft production in Hangzhou and Dongguan have put this equipment into practical use on a large scale. Implemented batch installation applications.<\/p>\n

\n

Axial feed through grinding<\/h2>\n<\/p>\n

\"\u65e0\u5fc3\u78e8\u524a_\u8d2f\u7a7f\u78e8\u524a_\u78e8\u524a\u52a0\u5de5\u884c\u4e1a\u6807\u51c6\u6c47\u603b\"<\/p>\n

The axis of the guide wheel and the axis of the grinding wheel form an oblique angle of one to six degrees. Under such conditions, the workpiece will automatically displace along the axis while rotating. This mechanism eliminates dependence on manual feeding. As a result, high productivity performance can be achieved while operating conditions remain stable.<\/p>\n

This grinding method can only be used to process the outer cylindrical surface. As for the stepped shaft and those special-shaped surfaces, it cannot be produced. The 2025 national standard GB\/T 24738 clearly stipulates that the surface roughness Ra must be between 0.4 and 0.8 microns.<\/p>\n

\n

Applicable scenarios for plunge grinding<\/h2>\n<\/p>\n

Adjust the axes of the guide wheel and the grinding wheel to keep them parallel. Fix the workpiece on the pallet and prevent the workpiece from moving in the axial direction. The grinding wheel performs the feed operation in the transverse direction and cuts in. This setting can grind the surface and annular grooves.<\/p>\n

It is used to support bearing factories in grinding raceways, and is also used to grind the grooves of spline shafts. Its single cutting depth range is 0.05 mm to 0.15 mm. If the feed speed is too fast, the surface of the workpiece will be easily burned and appear blue.<\/p>\n

\n

Centerless internal grinding<\/h2>\n<\/p>\n

Center the outer dome of the workpiece on the roller or support block, then use the eccentric electromagnetic suction ring to rotate the workpiece, and then insert the grinding wheel into the hole to perform the grinding task. At this time, the outer circle exists as a reference point, and the concentricity of the inner and outer circles needs to be controlled within 5 microns.<\/p>\n

Bearing ring inner groove grinding is a typical application. In 2025, the measured data of Luoyang LYC showed that its roundness error was controlled within 2 microns, while the radial runout did not exceed 3 microns.<\/p>\n

\n

The material of the guide wheel matches the rotation speed<\/h2>\n<\/p>\n

\"\u78e8\u524a\u52a0\u5de5\u884c\u4e1a\u6807\u51c6\u6c47\u603b_\u8d2f\u7a7f\u78e8\u524a_\u65e0\u5fc3\u78e8\u524a\"<\/p>\n

The guide wheel is usually made of materials such as diamond or CBN, and its rotation speed is generally set to a ratio range of 0.3 to 0.5 times the grinding wheel speed. When the rotational speed is at a low level, the grinding force is relatively large, which is more suitable for fine grinding operations. On the contrary, if the rotation speed is selected higher, then it is more suitable for removing excess margin.<\/p>\n

This is industry comparison data in 2024. The life of CBN guide wheels is longer than that of diamond. The specific time is 3 to 5 times longer, but the unit price of purchase is 40% higher, so it is more cost-effective to use diamond in small batch trial production.<\/p>\n

\n

Industry standards and parameter comparison<\/h2>\n<\/p>\n

Regarding grinding tools, the relevant standards are concentrated in GB\/T 24738 and JB\/T 7353. In the 2025 revision, requirements for thermal deformation compensation have been added, as well as requirements for automatic dressing of grinding wheels.<\/p>\n

The actual workshop parameters deviate greatly during execution, so we recommend that you perform the dynamic balancing operation of the grinding wheel in accordance with the ISO 21927 standard, and strictly control the residual imbalance within 1 g cm.<\/p>\n

Does the centerless grinder you currently use in your factory use a diamond guide wheel or a CBN material during processing?

Grinding Grinding is a machining method that uses abrasives and grinding tools to remove excess material from the workpiece. It is a finishing process. It is mainly based on high-speed rotating cutting of grinding wheels. The processing accuracy can reach IT8~5 level and the surface roughness can reach micron level.<\/p>","protected":false},"author":1,"featured_media":2652,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[28],"tags":[1456,1457,689,1458],"class_list":["post-2651","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-machining","tag-centerless-grinders","tag-external-cylindrical-grinding","tag-grinding","tag-internal-cylindrical-grinding"],"_links":{"self":[{"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/posts\/2651","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/comments?post=2651"}],"version-history":[{"count":0,"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/posts\/2651\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/media\/2652"}],"wp:attachment":[{"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/media?parent=2651"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/categories?post=2651"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/endlfh.com\/de\/wp-json\/wp\/v2\/tags?post=2651"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
