1、較低的攻牙扭力。BALAX公司在揉捏絲錐的引導(dǎo)方面與其他公司不同。其他公司的過渡牙在刃磨時(shí)，其牙峰是平的，而BALAX的過渡牙仍然是尖的，這樣在攻牙時(shí)加工阻力比較小，絲錐的扭力也相對(duì)較小。 </p> <p> 2、規(guī)范庫(kù)存各種精度、尺度的絲錐，包括各種等級(jí)加大絲錐。在現(xiàn)代加工中，經(jīng)常會(huì)需求一些加大的絲錐，基于此，BALAX公司出產(chǎn)了各種加大尺度的絲錐，其等級(jí)用“H”和“D”來(lái)表明。 </p> <p> 3、外表涂層處理。BALAX針對(duì)各種加工資料有各種相對(duì)應(yīng)的外表涂層處理，使絲錐能發(fā)作更大的效能。 </p> <p> 鍍鈦加工廠家BALAX揉捏絲錐介紹： </p> <p> <br /> 先對(duì)質(zhì)料停止熱處置，熱處置能夠讓材量到達(dá)相對(duì)合理的硬度范疇內(nèi)，從而包管沖針的一般使用。</p><div
