Plan intermediate and final inspection.<\/strong> Do not defer all measurement until after the last operation if an earlier process can consume the remaining allowance.<\/li>\n<\/ol>\nThese are planning questions, not a blanket instruction that every bore needs both processes. In some parts, internal grinding alone may meet the print. In others, honing may be appropriate after a different boring or grinding operation. A process engineer should confirm the sequence against material hardness, bore dimensions, tolerance relationships, and functional testing requirements.<\/p>\n
Inspection must match the geometry<\/h2>\n
Use a calibrated bore gauge or air gauge for diameter where appropriate, but pair size readings with a form method when the print controls roundness, cylindricity, or axis. A CMM may evaluate location and alignment relative to datums, while a dedicated form instrument can give more detailed bore geometry. The right method depends on access, tolerance, surface condition, and measurement uncertainty.<\/p>\n
For texture, specify whether Ra, Rz, or another parameter is required and how the instrument is oriented. A stylus can be difficult to place consistently in a small or deep bore; a reading near the mouth may not represent the working zone. If the part is a seal or bearing interface, a functional test or supplier-defined verification may complement dimensional inspection, but it should not replace drawing requirements without agreement.<\/p>\n
Measure after cleaning and temperature stabilization. Abrasive residue, honing oil, burrs at cross holes, or temperature differences can distort the result. Record the location and orientation of measurements so that supplier and customer results are comparable.<\/p>\n
Make the drawing useful to manufacturing<\/h2>\n
A decision-ready print should show bore diameter and tolerance, the datum reference, any required form or position control, surface texture, material and heat-treatment condition, and the inspection expectation. Where a seal or shaft drives function, identify the mating component or fit class rather than relying on a generic note. Clarify whether dimensions are measured before or after coating, plating, or a later assembly operation.<\/p>\n
When the bore is deep, interrupted, thin-walled, or unusually small, include a section view or model detail that makes access and support clear. If a process change is permitted, define the accepted result rather than requiring a named operation without explaining why. This gives manufacturing room to select a suitable route while preserving the engineering requirement.<\/p>\n
FAQ<\/h2>\nDoes honing always follow internal grinding?<\/h3>\n
No. Honing is used when its surface or geometry contribution is needed. If grinding already achieves all specified characteristics, an extra operation may add cost and risk without improving function.<\/p>\n
Can honing correct a bore that is out of alignment?<\/h3>\n
It may refine some bore errors, but it should not be assumed to relocate an axis relative to external datums. Establish the required axis relationship and available stock before selecting a corrective process.<\/p>\n
Which process gives a crosshatched bore?<\/h3>\n
Honing commonly produces a crosshatch from its combined motion. The required pattern and texture still need functional definition and suitable inspection; appearance alone is not proof of acceptance.<\/p>","protected":false},"excerpt":{"rendered":"
A bore can measure on size and still fail its function. The axis may be tapered, lobed, misaligned, or too rough for the mating shaft or seal. Internal grinding and honing address different parts of that problem: internal grinding is a stock-removal process used to establish bore size and geometry; honing is commonly used to […]<\/p>\n","protected":false},"author":1,"featured_media":3353,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-3330","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/posts\/3330","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/comments?post=3330"}],"version-history":[{"count":5,"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/posts\/3330\/revisions"}],"predecessor-version":[{"id":3352,"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/posts\/3330\/revisions\/3352"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/media\/3353"}],"wp:attachment":[{"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/media?parent=3330"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/categories?post=3330"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.jccncmachining.com\/de\/wp-json\/wp\/v2\/tags?post=3330"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
