stage, the key question is not:<br data-start=\"2055\" data-end=\"2058\" \/>\u201cCan this part be machined?\u201d<\/p>\n<p data-start=\"2090\" data-end=\"2187\">It is:<br data-start=\"2096\" data-end=\"2099\" \/>\u201cCan the system be delivered on time, with acceptable documentation and without rework?\u201d<\/p>\n<p data-start=\"2189\" data-end=\"2234\">Common risks in electronics projects include:<\/p>\n<ul data-start=\"2235\" data-end=\"2372\">\n<li data-section-id=\"2kk45s\" data-start=\"2235\" data-end=\"2278\">Late mechanical parts delaying assembly<\/li>\n<li

changes after PCB design is fixed<\/li>\n<\/ul>\n<p data-start=\"2374\" data-end=\"2495\">An EMS-oriented CNC milling approach helps reduce these risks by aligning machining with downstream requirements such as:<\/p>\n<ul data-start=\"2496\" data-end=\"2648\">\n<li data-section-id=\"1hgdtmm\" data-start=\"2496\" data-end=\"2535\">Grounding and electrical interfaces<\/li>\n<li

glance<\/h2>\n<p data-start=\"2885\" data-end=\"2992\">Many buyers look for suppliers who can deliver complete machining workflows rather than isolated processes.<\/p>\n<p data-start=\"2994\" data-end=\"3041\">A typical EMS-aligned machining chain includes:<\/p>\n<ul data-start=\"3042\" data-end=\"3212\">\n<li data-section-id=\"1g25ltj\" data-start=\"3042\" data-end=\"3086\">CNC milling (3-\/4-axis, 3+2 positioning)<\/li>\n<li data-section-id=\"sougof\" data-start=\"3087\" data-end=\"3125\">CNC turning or mill-turn processes<\/li>\n<li data-section-id=\"w3j0th\" data-start=\"3126\" data-end=\"3162\">EDM and grinding (when required)<\/li>\n<li data-section-id=\"kfumef\" data-start=\"3163\" data-end=\"3212\">Measurement and inspection with documentation<\/li>\n<\/ul>\n<p data-start=\"3214\" data-end=\"3290\">This reduces handoffs and simplifies coordination in time-critical projects.<\/p>\n<h3 data-section-id=\"15jn095\" data-start=\"3297\" data-end=\"3341\">2.1 3-\/4-axis + 3+2: practical relevance<\/h3>\n<p data-start=\"3343\" data-end=\"3385\">Most electronics components are prismatic:<\/p>\n<ul data-start=\"3386\" data-end=\"3439\">\n<li data-section-id=\"1dkwc0x\" data-start=\"3386\" data-end=\"3400\">Enclosures<\/li>\n<li data-section-id=\"1xk8qzb\" data-start=\"3401\" data-end=\"3411\">Plates<\/li>\n<li data-section-id=\"8g424c\"

parts, 3- or 4-axis machining with 3+2 positioning is often sufficient.<\/p>\n<p data-start=\"3524\" data-end=\"3539\">Key advantages:<\/p>\n<ul data-start=\"3540\" data-end=\"3624\">\n<li data-section-id=\"1lyigsv\" data-start=\"3540\" data-end=\"3568\">Reduced setup complexity<\/li>\n<li data-section-id=\"1pivipr\" data-start=\"3569\" data-end=\"3590\">Stable tolerances<\/li>\n<li

(turning)<\/li>\n<\/ul>\n<p data-start=\"3796\" data-end=\"3820\">A combined workflow can:<\/p>\n<ul data-start=\"3821\" data-end=\"3926\">\n<li data-section-id=\"dd46fe\" data-start=\"3821\" data-end=\"3851\">Reduce supplier interfaces<\/li>\n<li data-section-id=\"143ennp\" data-start=\"3852\" data-end=\"3889\">Minimise intermediate inspections<\/li>\n<li data-section-id=\"u9e5if\"

data-start=\"3973\" data-end=\"4021\">Certain geometries require additional processes:<\/p>\n<ul data-start=\"4022\" data-end=\"4112\">\n<li data-section-id=\"1r8ulsz\" data-start=\"4022\" data-end=\"4048\">Sharp internal corners<\/li>\n<li data-section-id=\"q7g62s\" data-start=\"4049\" data-end=\"4078\">Thin ribs or narrow slots<\/li>\n<li data-section-id=\"s8wnmr\" data-start=\"4079\" data-end=\"4112\">Specific surface finish zones<\/li>\n<\/ul>\n<p data-start=\"4114\" data-end=\"4205\">EDM and grinding are typically used selectively where standard machining is not sufficient.<\/p>\n<h3 data-section-id=\"ms3ddz\" data-start=\"4212\" data-end=\"4244\">2.4 Metrology and inspection<\/h3>\n<p data-start=\"4246\" data-end=\"4303\">Reliable delivery depends on transparent quality control.<\/p>\n<p data-start=\"4305\" data-end=\"4341\">Typical inspection elements include:<\/p>\n<ul data-start=\"4342\" data-end=\"4441\">\n<li data-section-id=\"u7gm9y\"
