Next, lower your cutting speed (Vc) slightly and increase the feed rate (f) to force the insert deeper into the cut, stabilizing the bar. Ensure you are using an insert with a smaller nose radius (e.g., 0.4mm instead of 0.8mm) to minimize radial force vectors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BEYOND","offers":[{"title":"Default Title","offer_id":43607188275372,"sku":"S32T-MTJNR16","price":54.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/BEYOND-S32T-MTJNR16-indexable-boring-bar-32mm-CNC-internal-turning-toolholder.jpg?v=1782462155","url":"https:\/\/cnchome-beyond.com\/products\/s32t-mtjnr16-cnc-boring-bar-tool-holder-internal-turning","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
