齒(chi)(chi)向(xiang)(xiang)誤差(cha)：齒(chi)(chi)向(xiang)(xiang)誤差(cha)主要分(fen)布(bu)在分(fen)度圓柱體上(shang)，在全(quan)齒(chi)(chi)寬范圍(wei)內，兩個齒(chi)(chi)向(xiang)(xiang)線(xian)之間的(de)端面(mian)距離。齒(chi)(chi)向(xiang)(xiang)誤差(cha)的(de)原因(yin)是刀架和(he)(he)機(ji)(ji)床的(de)垂直進給方(fang)向(xiang)(xiang)與零件(jian)軸線(xian)偏移；滾(gun)齒(chi)(chi)機(ji)(ji)尾座頂中心與工作臺旋(xuan)轉(zhuan)中心之間存在偏差(cha)；計算差(cha)動(dong)掛輪時，誤差(cha)過大，導致(zhi)傳動(dong)鏈齒(chi)(chi)輪調整(zheng)制造誤差(cha)較大。此外，由于精(jing)(jing)度低，齒(chi)(chi)坯和(he)(he)滾(gun)齒(chi)(chi)夾具的(de)制造和(he)(he)安裝(zhuang)也(ye)(ye)會導致(zhi)齒(chi)(chi)向(xiang)(xiang)誤差(cha)。齒(chi)(chi)坯、機(ji)(ji)床、夾具等誤差(cha)也(ye)(ye)會導致(zhi)齒(chi)(chi)向(xiang)(xiang)誤差(cha)。齒(chi)(chi)面(mian)粗糙度：一般來(lai)說，齒(chi)(chi)面(mian)粗糙度差(cha)主要表現為啃牙(ya)、發紋、撕裂、魚(yu)鱗等。機(ji)(ji)床刀架滑板(ban)也(ye)(ye)會影(ying)響到(dao)滾(gun)齒(chi)(chi)的(de)齒(chi)(chi)向(xiang)(xiang)誤差(cha)，比如(ru)，刀架滑板(ban)和(he)(he)回轉(zhuan)軸線(xian)之間的(de)平行度。因(yin)此，提升(sheng)刀架導軌精(jing)(jing)度也(ye)(ye)是提升(sheng)滾(gun)齒(chi)(chi)精(jing)(jing)度的(de)一種方(fang)法。
