三者的區(qū)別
（1）再生制動(dòng)必須在伺服器正常工作時(shí)才起作用,在故障,急停,電源斷電時(shí)等情況下無(wú)法制動(dòng)電機(jī).動(dòng)態(tài)制動(dòng)器和電磁制動(dòng)工作時(shí)不需電源.
（2）再生制動(dòng)的工作是系統(tǒng)自動(dòng)進(jìn)行,而動(dòng)態(tài)制動(dòng)器和電磁制動(dòng)的工作需外部繼電器控制.
（3）電磁制動(dòng)一般在SV OFF后啟動(dòng),否則可能造成放大器過(guò)載.動(dòng)態(tài)制動(dòng)器一般在SV OFF或主回路斷電后啟動(dòng),否則可能造成動(dòng)態(tài)制動(dòng)電阻過(guò)熱.

主軸部件故障由于使用調(diào)速電機(jī)，數(shù)控機(jī)床主軸箱結(jié)構(gòu)比較簡(jiǎn)單，容易出現(xiàn)故障的部位是主軸內(nèi)部的刀具自動(dòng)夾緊機(jī)構(gòu)、自動(dòng)調(diào)速裝置等。為保證在工作中或停電時(shí)刀夾不會(huì)自行松脫，刀具自動(dòng)夾緊機(jī)構(gòu)采用彈簧夾緊，并配行程開關(guān)發(fā)出夾緊或放松信號(hào)。若刀具夾緊后不能松開，則考慮調(diào)整松刀液壓缸壓力和行程開關(guān)裝置或調(diào)整碟形彈簧上的螺母，減小彈簧壓合量。此外，主軸發(fā)熱和主軸箱噪聲問(wèn)題，也不容忽視，此時(shí)主要考慮清洗主軸箱，調(diào)整潤(rùn)滑油量，保證主軸箱清潔度和更換主軸軸承，修理或更換主軸箱齒輪等。
直流電機(jī)試驗(yàn)安全操作規(guī)程
1.直流電動(dòng)機(jī)勵(lì)磁繞組在試驗(yàn)過(guò)程中嚴(yán)禁斷路和斷勵(lì)，兩個(gè)以上的勵(lì)磁繞組須正確地連接，以防超速事故。
2.直流電機(jī)的負(fù)載應(yīng)盡量從依次增加。
3.直流發(fā)電機(jī)的勵(lì)磁電流應(yīng)從依次增加。
4.做直流電機(jī)的超速試驗(yàn)時(shí)，應(yīng)加遮欄防護(hù)。
5.各種直流電機(jī)試驗(yàn)前，須檢查或調(diào)整其電刷至準(zhǔn)確的中性線上。
6.1OA以上的直流電流線路的通斷，應(yīng)用接觸器完成，禁止用手直接操作刀閘。即使拉斷小電流刀閘也必須戴手套，以防電弧燒傷。
7.禁止戴線手套接觸轉(zhuǎn)動(dòng)部分。

三聽：聽石材的敲擊聲音。一般而言，質(zhì)量好的，內(nèi)部致密均勻且無(wú)顯微裂隙的石材，其敲擊聲清脆悅耳;相反，若石材內(nèi)部存在顯微裂隙或細(xì)脈或因風(fēng)化導(dǎo)致顆粒間接觸變松，敲擊聲粗啞。四試：用簡(jiǎn)單的試驗(yàn)方法來(lái)檢驗(yàn)石材質(zhì)量好壞。通常在石材的背面滴上一小滴墨水，如墨水很快四處分散浸出，即表示石材內(nèi)部顆粒較松或存在顯微裂隙，石材質(zhì)量不好;反之，若墨水滴在原處不動(dòng)，則說(shuō)明石材致密，質(zhì)地好。在成品板材的挑選上，由于石材原料是天然的，不可能質(zhì)地完全相同，在開采、加工中工藝的水平也有差別。
