YaHei";">pom賽鋼加工如何防止產品變形？經常會有原料加工方面的朋友問到這樣的問題，因為一旦產品發(fā)生了變形，無疑就宣告了工藝流程的失敗，需要及時的去調整工藝流程各項參數(shù)。變形主要有幾種因素引起的：夾緊變形，POM材料不像鋼材，夾緊會產生變形，粗加工后松開后產品又回復到原來狀態(tài)了，2.熱變形，加工時會產生大量的熱，而POM材料對熱很敏感，從而產生變形3.彈性變形，POM材料韌性很好，切削時，產品會產生彈性變形，刀具離開后會產品會恢復一定的變形量。針對這些因素可以采取以下以下措施：1.粗加工前將毛胚做標準，再開粗，盡量多分幾次加工，減少變形量。也可以用粘膠水的方式加工，這樣變形就很小。2.采用白鋼刀（高速鋼刀具的俗稱）加工而不用合金刀，因為白鋼刀很鋒利，切削時產生的熱量相對要小些。3.切削量不要太大。</span> </p><p> POM板材的硬度是多少？聚縮醛 ( POM ) 性質為結晶性熱可塑性塑料，具明顯熔點165~175℃，性質尤其接近金屬，一般稱其為塑鋼。POM硬度是118-122R的硬度, 型號不同硬度也是不一樣的，POM材料各個型號的硬度相差也不是很大?？傮w來說POM的硬度是比較高的，洛氏硬度達到D80-85Z這樣的，在工程塑料里面是屬于高硬度的材料的，就硬度方面跟鋼材有的一比，在其他的一些加工性能上，POM的也是不錯的，做一些零配件，軸承，齒輪等，也是不錯的?，F(xiàn)在工程塑料是一個新興行業(yè)，好多能代替鋼材，具有金屬材料沒有的性能，像絕緣，耐磨，耐酸堿等。由于POM結晶度高、體積收縮大，為防止制品出現(xiàn)空洞、凹痕等缺陷，必須要有足夠的保壓時間進行補縮。</p><div

style="text-indent:25px">pom塑料耐溫多少度？POM是結晶型塑料,密度為1.42g/cm3,它的鋼性很好,俗稱“賽鋼”。POM（聚甲醛）是一種光滑，有光澤，堅硬且致密的材料，淡黃色或白色，可以在-50-110°C的溫度范圍內長時間使用。它的耐磨性和自潤滑性也很出色，對大多數(shù)工程塑料而言，它具有良好的耐油性和抗過氧化物性能。非常耐酸，堿和紫外線輻射。熔點是：熔點175℃，軟化點：150℃，熱變形溫度HDT：155℃?？傊?，POM的高溫耐受性約為110℃，并且不超過軟化點。POM板材價格分不同顏色也分國產還是進口。一般普通的，價格在14000元/噸左右，有些是按平方來和厚度來算。南京耐摩擦pom賽鋼板價格</p><p
