細(xi)木(mu)工(gong)板(ban)(ban)俗稱大芯(xin)(xin)板(ban)(ban)，木(mu)芯(xin)(xin)板(ban)(ban)，木(mu)工(gong)板(ban)(ban)， 是由(you)兩(liang)片單(dan)(dan)板(ban)(ban)中間膠(jiao)(jiao)壓(ya)拼接木(mu)板(ban)(ban)而成。細(xi)木(mu)工(gong)板(ban)(ban)的(de)(de)兩(liang)面膠(jiao)(jiao)粘單(dan)(dan)板(ban)(ban)的(de)(de)總厚(hou)(hou)度不得小于(yu)(yu)3mm。屬于(yu)(yu)膠(jiao)(jiao)合板(ban)(ban)。由(you)于(yu)(yu)細(xi)木(mu)工(gong)板(ban)(ban)是特殊(shu)的(de)(de)膠(jiao)(jiao)合板(ban)(ban)，所(suo)以在(zai)生產工(gong)藝中也要同(tong)時遵循對稱原則，以避免(mian)板(ban)(ban)材翹曲變形，作為一(yi)種厚(hou)(hou)板(ban)(ban)材，細(xi)木(mu)工(gong)板(ban)(ban)具有普通厚(hou)(hou)膠(jiao)(jiao)合板(ban)(ban)的(de)(de)漂(piao)亮外觀和相近的(de)(de)強(qiang)度，但(dan)細(xi)木(mu)工(gong)板(ban)(ban)比厚(hou)(hou)膠(jiao)(jiao)合板(ban)(ban)質地輕(qing)，耗膠(jiao)(jiao)少(shao)，投資省，并且給人以實木(mu)感(gan)，滿足消費者對實木(mu)家具的(de)(de)渴求。

芯板(ban)(ban)的(de)主(zhu)要作(zuo)用是為板(ban)(ban)材提供一定的(de)厚度(du)(du)和強度(du)(du)，上(shang)下(xia)中板(ban)(ban)的(de)主(zhu)要作(zuo)用是使(shi)板(ban)(ban)材具有(you)足夠的(de)橫向強度(du)(du)，同時緩沖因木芯板(ban)(ban)的(de)不平整(zheng)給板(ban)(ban)面(mian)平整(zheng)度(du)(du)帶來的(de)不良(liang)影(ying)響，最上(shang)面(mian)的(de)面(mian)皮(薄單板(ban)(ban)，一般不超過1MM)除了使(shi)板(ban)(ban)面(mian)美(mei)觀以(yi)外，還(huan)可以(yi)增(zeng)加板(ban)(ban)材的(de)縱向強度(du)(du)。
