Matrix Tsim ntawm Electroplated CBN Abrasive cuab yeej
High precision narrow and deep grooves have always been a challenge in mechanical processing. Previously, narrow and deep grooves with a width of>2 hli ntawm cov khoom siv zoo tib yam feem ntau yog ua ntej milled nrog lub ntswj milling cutter, kho cua sov, thiab tom qab ntawd hauv av nrog thinner resin lossis ceramic bond sib tsoo log. Cov txheej txheem no muaj kev ua haujlwm tsawg, kev sib tsoo lub log tsis muaj zog, tsis zoo rigidity, thiab luv lifespan, ua rau nws nyuaj rau kev ua tiav siab machining raug. Los ntawm kev siv cov kev sib tsoo zoo tib yam qeeb pub sib tsoo cov txheej txheem, high-precision nqaim thiab sib sib zog nqus grooves tuaj yeem raug machined tom qab ib qho kev sib tsoo kub ntawm lub workpiece. Rau nqaim thiab tob grooves nrog ib tug dav ntawm<2mm, milling processing has high cost and low accuracy; When using ordinary grinding wheels for slow feed grinding, the thickness of the working area of the grinding wheel is very thin, and the amount of dressing is large. It is easy to break during grinding and dressing, and the processing cost is high. In recent years, electroplated superhard abrasive wheels have been widely used for high-precision slot slow feed grinding. Electroplated CBN grinding wheels have been used abroad to slowly feed grind narrow and deep grooves with a width of 1.52mm, a depth of 6.35mm, and a radius of 0.38mm on 4340 steel parts with a hardness of HRC42. Electroplated CBN grinding wheels are also used domestically to slowly feed and grind narrow and deep grooves with a width of 1.5mm on ordinary steel. Many aviation parts made of difficult to machine materials have various high-precision grooves, especially the machining of high-precision tooth grooves and narrow and deep straight grooves at the root of aircraft turbine blades, which has always been a difficulty in blade machining in China. This article will introduce the design of the grinding tool matrix for slow feed grinding of narrow and deep grooves with electroplated CBN grinding wheels.
