激光切割發生過燒怎么辦？

1 材料表面

碳(tan)鋼暴露在(zai)空(kong)氣中會氧(yang)化并(bing)在(zai)表面(mian)產生氧(yang)化皮(pi)(pi)或(huo)氧(yang)化膜(mo)。這層膜(mo)/皮(pi)(pi)的(de)厚度不(bu)(bu)均勻(yun)或(huo)者翹起未(wei)緊貼板材，就會導(dao)致板材對(dui)激光的(de)吸收不(bu)(bu)均勻(yun)，從而產生的(de)熱(re)量(liang)(liang)也不(bu)(bu)穩(wen)定。這影響的(de)是上(shang)述切(qie)割(ge)的(de)第②個步驟。切(qie)割(ge)前，盡量(liang)(liang)選擇(ze)表面(mian)狀態(tai)好的(de)一面(mian)朝上(shang)放(fang)置。

2 熱量堆積

良(liang)好(hao)的(de)切(qie)割狀態應(ying)該是：激光(guang)照射材料產(chan)生的(de)熱(re)量(liang)、以(yi)及氧化燃燒產(chan)生的(de)熱(re)量(liang)都能有效地向周圍擴(kuo)散，并(bing)且能得到(dao)有效的(de)冷卻(que)。如果冷卻(que)不(bu)充分(fen)，就有可能會引(yin)起過(guo)燒。

當(dang)加工軌跡(ji)涉及多個小(xiao)尺(chi)寸形狀(zhuang)時，隨著切(qie)(qie)割的進行，熱量會不斷地堆積，當(dang)切(qie)(qie)到后(hou)半部分時很(hen)容易發(fa)生過燒(shao)

解決方(fang)法是(shi)盡量讓加工圖形(xing)分散開來，從而使(shi)熱量得到有(you)效的分散。

3 尖角部位發(fa)生過燒

碳鋼暴露在空氣中會(hui)氧(yang)化(hua)并(bing)在表(biao)面(mian)產生氧(yang)化(hua)皮或氧(yang)化(hua)膜。這層膜/皮的(de)(de)厚(hou)度不均勻或者(zhe)翹(qiao)起未緊貼(tie)板(ban)材(cai)，就會(hui)導致(zhi)板(ban)材(cai)對激(ji)光的(de)(de)吸收不均勻，從而產生的(de)(de)熱(re)量也(ye)不穩定。這影響的(de)(de)是(shi)上(shang)述切割的(de)(de)第②個步驟。切割前，鐵板(ban)卷圓加工多少錢(qian)，盡(jin)量選擇(ze)表(biao)面(mian)狀態好的(de)(de)一(yi)面(mian)朝(chao)上(shang)放(fang)置。

焦(jiao)點位置調整對切割質量的影響

由于激光(guang)功(gong)(gong)率密(mi)度(du)(du)對切割速度(du)(du)影響很大，鐵板(ban)卷圓加(jia)工廠，透鏡(jing)(jing)焦(jiao)長(chang)(chang)(chang)的選擇(ze)是個重要(yao)問題。激光(guang)束聚(ju)焦(jiao)后光(guang)斑(ban)大小與透鏡(jing)(jing)焦(jiao)長(chang)(chang)(chang)成正比(bi)，光(guang)束經短(duan)焦(jiao)長(chang)(chang)(chang)透鏡(jing)(jing)聚(ju)焦(jiao)后光(guang)斑(ban)尺寸很小，焦(jiao)點處功(gong)(gong)率密(mi)度(du)(du)很高(gao)，對材料切割很有(you)(you)利；但它的缺點是焦(jiao)深很短(duan)，調節(jie)余量(liang)小，一般比(bi)較適用于高(gao)速切割薄型材料。由于長(chang)(chang)(chang)焦(jiao)長(chang)(chang)(chang)透鏡(jing)(jing)有(you)(you)較寬焦(jiao)深，只要(yao)具有(you)(you)足夠功(gong)(gong)率密(mi)度(du)(du)，比(bi)較適合切割厚工件。

在(zai)(zai)確定使用何種焦(jiao)長(chang)的(de)透(tou)鏡以后，焦(jiao)點(dian)與工件(jian)表面(mian)(mian)的(de)相(xiang)對位置(zhi)對保證切(qie)(qie)割質(zhi)量尤為重(zhong)要(yao)。由于焦(jiao)點(dian)處功率密度，大(da)多數情況下，切(qie)(qie)割時焦(jiao)點(dian)位置(zhi)剛處在(zai)(zai)工件(jian)表面(mian)(mian)，或稍微(wei)在(zai)(zai)表面(mian)(mian)以下。在(zai)(zai)整(zheng)個切(qie)(qie)割過程中(zhong)，確保焦(jiao)點(dian)與工件(jian)相(xiang)對位置(zhi)恒(heng)定是獲得穩(wen)定的(de)切(qie)(qie)割質(zhi)量的(de)重(zhong)要(yao)條件(jian)。有時，透(tou)鏡工作中(zhong)因冷卻不善而受熱從而引起焦(jiao)長(chang)變(bian)化，這就需要(yao)及時調整(zheng)焦(jiao)點(dian)位置(zhi)。

當(dang)焦點(dian)處于位置時，割(ge)(ge)縫、效率，切(qie)(qie)割(ge)(ge)速度可(ke)獲得切(qie)(qie)割(ge)(ge)結果。

在大多數應用情(qing)況(kuang)下，光(guang)束焦點(dian)調(diao)整到剛處(chu)于噴(pen)嘴下。噴(pen)嘴與(yu)工件表面(mian)間(jian)距一般為1.5mm左右。

2）加工(gong)(gong)的工(gong)(gong)件須(xu)夾(jia)持牢靠，嚴(yan)禁(jin)工(gong)(gong)件裝夾(jia)不(bu)緊(jin)就開(kai)始切割。

3）嚴禁在砂輪(lun)平(ping)面上(shang)，修磨工件的毛刺，防止砂輪(lun)片(pian)碎裂。

4）切割時操作(zuo)者須偏離砂輪片正面，鐵(tie)板(ban)卷(juan)圓(yuan)加工價格(ge)，并戴(dai)好(hao)防護眼鏡。

5）嚴禁使用已有殘缺的(de)砂(sha)輪(lun)片，切割時應防止火星四濺(jian)，并遠離(li)物品(pin)。

6）裝夾工件時應裝夾平穩牢固(gu)，防(fang)護(hu)罩須安裝正(zheng)確，裝夾后應開機空運(yun)轉檢(jian)查，不(bu)得(de)有(you)抖(dou)動和(he)異常噪聲。

7）中途(tu)更換(huan)新切割片或(huo)砂輪片時，不要將鎖緊螺母過于用力，防止鋸片或(huo)砂輪片崩裂發生意(yi)外。

8）須穩握切割機手把(ba)均勻用(yong)力垂直(zhi)下切，而且固定端要牢固可靠(kao)。
