With the direct-drive technology, linear motor and the traditional "rotary servo motor + ball screw" in contrast to drive the instry's concern.
The British in 1845 had invented the linear electric motor, but the linear motor air-gap is too large resulting in low efficiency, can not be applied. 19th century 70s Kollmorgen also launched, but e to the high cost and low efficiency limited its development. 70s until the 20th century, the linear motor to the progressive development and application of some special area, the 20th century, the beginning of 90's linear motor used in the machine manufacturing instry, now some of the world's technologically advanced manufacturers of machining centers in its application of high-speed machine tools, foreign well-known enterprises such as DMG, Ex-cell-O, Ingersoll, CINCI ATI, GROB, MATEC, MAZAK, FANUC, SODICK have rolled out the use of linear motor centers of the high-speed and high precision.
HIWIN linear procts as the world leader in the ball screw and linear slide after success in recent years on its own R & D and proction of a linear motor, and in the field of high-speed and high precision good performance.
HIWIN below the main reference of the company's advanced high-speed silent SUPER S series screw-type (DN value of 220,000) and the linear motor HIWIN several major features in some of the more so, for the relevant instry to provide a reference.
Accuracy:
Precision linear motor drive mechanism by a simple interpolation to rece the lag issues, positioning accuracy and reprocibility precision, absolute precision, through the position detection feedback control will be more "rotary servo motor + ball screw" high, and easy to implement.
Linear motor positioning accuracy of up to 0.1μm. "Rotary servo motor + ball screw" up to 2 ~ 5μm, and the requirements of CNC-servo motors - even without coupling gap - thrust bearing - Cooling System - high-precision rolling guide - Nut Block - table closed-loop system as a whole transmission part to lighter, higher precision grating.
To achieve higher stability, "rotary servo motor + ball screw" to take al-axis drive, linear motor is a high-heat components, the cold to take strong measures to achieve the same end, the linear motor will pay a higher price .
Price comparison:
Linear motor prices to much higher prices, which is restricted by linear motor of the reasons for wider application.
Speed comparison:
Speed linear motor with a considerable advantage, linear motor speed of 300m/min, acceleration reached 10g; ball screw speed of 120m/min, acceleration is 1.5g. Speed and acceleration from the contrast, the linear motor has a considerable advantage, and the linear motor in the successful resolution of fever after the speed will improve on that level, and "rotary servo motor + ball screw" in the speed limit has been difficult to further increase more.
Because of the dynamic response from the movement of inertia and the gap as well as institutional issues such as the complexity of linear motor also has an absolute advantage.
Speed control on the linear motor because of its fast response, wide speed range, you can start to achieve the highest instantaneous speed, high-speed run-time and can stop quickly. Speed range up to 1:10000.
Comparison of energy consumption:
Linear motors provide the same torque in the power consumption at the time of the "rotating servo motor + ball screw" more than doubled, "rotary servo motor + ball screw" is energy saving, by type power transmission components, linear motor control system reliability by stability, a great influence on the perimeter to take effective protective measures and the magnetic traps, rolling off a strong magnetic field on the impact of rail and the absorption of iron magnetic st.
Following this example to make it easier for us to know the linear motor and the "rotating servo motor + ball screw" a number of characteristics:
Japan, a company high-speed gantry type machining center. X, Y-axis linear motor drive using V = 120m/min. Why does the company "spin servo motor + ball screw (HIWIN SUPER S series)"? SUPER S Although the DN as the value has gone through a screw from the traditional 70000-150000 to 220000 of the acceleration process, but because of the weakness of pure mechanical transmission, the line speed, acceleration, increased range of travel is always limited . Φ40 × 20mm if selected proct is vmax = 110m/min, e to the high speed nmax = 5500r/min trip by the critical speed range Nc constraints obviously not too long.
If the large lead Φ40 × 40mm procts, while Vmax = 220m/min, which obviously can not meet the high positioning accuracy of occasions. DN values to achieve 220,000 reflected from one aspect of HIWIN design, manufacturing standards. If we choose Φ40 × 20 (double) mm proct, in the n ≈ 4000 ~ 5000r/min, V = 80 ~ 100m/min state use, its safety, reliability, service life can be higher than expected. In fact so far, in the high-speed high-precision CNC machine cut gold (CNC forming machine tools other than) the speed is still V ≥ 120m/min using SUPER S Series driver did not see a successful example. In fact, "rotary servo motor + ball screw" the best applications are: the requirements V = 40 ~ 100m/min, acceleration of 0.8 ~ 1.5 (2.0) g, the accuracy of more than P3-class mid-range high-speed CNC equipment and some high-end number of control equipment.
Application of comparison:
In fact, the linear motor and the "rotating servo motor + ball screw" Despite the way the two drivers have their own advantages, but there are also its Achilles heel. Both have their own CNC machine tools on the scope of application of the best.
Linear motor drive CNC equipment in the following areas of unique advantages: high-speed, ultra high-speed, high acceleration and large-volume proction, will require a location more than the movement, speed and direction of the frequent changes in the size of the occasion. For example, the automobile instry and IT instry, proction lines, sophisticated manufacturing mold.
Large, long journey of high speed machining centers, aerospace manufacturing instry in light alloy, thin-walled, metal removal rate of the overall component "hollowing" processing. Such as the United States CINCI ATI's "Hyper Mach" Machining Center (46m); Japan MAZAK's "HYPERSONIC 1400L ultra-high-speed machining center.
High dynamic performance, low-speed and high-speed mobility with the time, the dynamics of a highly sensitive precision positioning. For example, Sodick, represented a new generation of high-performance CNC EDM, CNC ultra-precision machine tools, a new generation of CPC crankshaft grinders, cam grinders, CNC lathes and other non-circular.
Light load, rapid special CNC equipment. DMG Germany, for instance, the "DML80 Fine Cutting" laser engraving, drilling machine, Belgium LVD's "AXEL3015S" laser cutting machine, MAZAK the "Hyper Cear510" high-speed laser processing machine.
Germany DMG proction all kinds of companies known for high-performance CNC equipment in its feed system servo linear motor used in earlier, but also a high rate of adoption (after models in the machine marked "Linear"), the company's two drive configurations are three types:
All configuration of the axis of linear motor drive "rapid-type" CNC equipment. For example: DMC85V Linear, DMC75V Linear, DMC105V Linear, DMC60H Linear, DMC80H Linear and DML80-Fine Cutting machines such as laser processing.
Mixed-driven. For example: DMF500 Linear dynamic large-scale vertical machining center column in the X axis (trip 5m) with linear motor, V = 100m/min; and in Y, Z axis is the "rotating ball screw servo motor +", V = 60m/min.
All configuration of the coordinate axis "rotary servo motor + ball screw" and "strong-type" processing center. For example: DMC63H high-speed horizontal machining center, V = 80m/min, acceleration of 1g, positioning accuracy of 0.008mm. In addition, DMC80H and DMC100H, DMC125H (o BLOCK), as well as such DMC60T.
The two drivers in Germany at the same time the use of DMG was also stating that they have their own advantages. Linear motor is much room for improvement, the future of linear motor technologies become more mature, and proction up and costs come down, the application will be more extensive, but saving energy, green manufacturing perspective, as well as to consider the characteristics of the two structures "rotary servo motor + ball screw" drive still has its broad market space. Will become a high-speed linear motor (ultra-high-speed), high-end CNC equipment in the mainstream at the same time drive, "rotary servo motor + ball screw" will continue to maintain its mid-range high-speed CNC equipment in the mainstream.

隨著直接驅動技術的發展，直線電機與傳統的「旋轉伺服電機+滾珠絲杠」的驅動方式的對比引起業界的關注。
1845年英國人就已經發明了直線電動機，但當時的直線電動機氣隙過大導致效率很低，無法應用。19世紀70年代科爾摩根也推出過，但因成本高效率低限制了它的發展。直到20世紀70年代以後，直線電機才逐步發展並應用於一些特殊領域，20世紀90年代直線電機開始應用於機械製造業，現在世界一些技術先進的加工中心廠家開始在其高速機床上應用，國外知名企業例如DMG、Ex-cell-O、Ingersoll、CINCI ATI、GROB、MATEC、MAZAK、FANUC、SODICK都陸續推出使用直線電機的高速高精加工中心。
HIWIN做為世界線性產品的領導者，在滾珠絲杠和線性滑軌方面取得成功後，於近幾年自行研發和生產了直線電機，並且在高速高精領域取得不錯的業績。
下面主要參考HIWIN公司的先進的高速靜音式絲杠 SUPER S 系列（DN值達22萬）和HIWIN的直線電機在幾個主要特性上做一些比較，為相關業者提供一個參考。
精度比較：
精度方面直線電機因傳動機構簡單減少了插補滯後的問題，定位精度、重現精度、絕對精度，通過位置檢測反饋控制都會較「旋轉伺服電機+滾珠絲杠」高，且容易實現。
直線電機定位精度可達0.1μm。「旋轉伺服電機+滾珠絲杠」最高達到2~5μm，且要求CNC-伺服電機-無隙連軸器-止推軸承-冷卻系統-高精度滾動導軌-螺母座-工作台閉環整個系統的傳動部分要輕量化，光柵精度要高。
若想達到較高平穩性，「旋轉伺服電機+滾珠絲杠」要採取雙軸驅動，直線電機是高發熱部件，需採取強冷措施，要達到相同目的，直線電機則要付出更大的代價。
價格比較：
價格方面直線電機的價格要高出很多，這也是限制直線電機被更廣泛應用的原因。
速度比較：
速度方面直線電機具有相當大的優勢，直線電機速度達到300m/min，加速度達到10g；滾珠絲杠速度為120m/min，加速度為1.5g。從速度上和加速度的對比上，直線電機具有相當大的優勢，而且直線電機在成功解決發熱問題後速度還會進一步提高，而「旋轉伺服電機+滾珠絲杠」在速度上卻受到限制很難再提高較多。
從動態響應上因為運動慣量和間隙以及機構復雜性等問題直線電機也佔有絕對的優勢。
速度控制上直線電機因其響應快，調速范圍更寬，可以實現啟動瞬間達到最高轉速，高速運行時又能迅速停止。調速范圍可達到1：10000。
能耗比較：
直線電機在提供同樣轉矩時的能耗是「旋轉伺服電機+滾珠絲杠」一倍以上，「旋轉伺服電機+滾珠絲杠」屬於節能、增力型傳動部件，直線電機可靠性受控制系統穩定性影響，對周邊的影響很大必須採取有效隔磁與防護措施，隔斷強磁場對滾動導軌的影響和對鐵屑磁塵的吸附。
通過以下這個例子更容易使大家了解直線電機和「旋轉伺服電機+滾珠絲杠」的一些特點：
日本某公司超高速龍門式加工中心。X、Y軸採用直線電動機驅動V=120m/min。該公司為何不應用「旋轉伺服電機+滾珠絲杠(HIWIN SUPER S 系列）」？因為SUPER S雖然DN值已經歷了從傳統絲杠7萬到15萬再到22萬的提速進程，但由於存在純機械傳動的軟肋，其線速度、加速度、行程范圍的增加總是有限的。若選用Φ40×20mm的產品，則vmax=110m/min，因nmax=5500r/min轉速很高，行程范圍受臨界轉速Nc的制約顯然不可能太長。
若採用大導程Φ40×40mm產品，則Vmax=220m/min，這顯然又不能滿足定位精度高的場合。能達到DN值22萬從一個側面反映了HIWIN的設計、製造水準。如果我們選擇Φ40×20(雙頭)mm產品，在n≈4000~5000r/min，V=80～100m/min狀態下使用，其安全性、可靠性、工作壽命均可高於預期值。事實上到目前為止，在高速高精CNC金切機床中(CNC成形機床除外)速度V≥120m/min仍採用SUPER S系列驅動的成功範例未見到。實際上「旋轉伺服電機+滾珠絲杠」的最佳應用場合是：要求V=40~100m/min，加速度0.8~1.5(2.0)g，精度P3級以上的中檔高速數控裝備和部分高檔數控裝備。
應用比較：
事實上，直線電機和「旋轉伺服電機+滾珠絲杠」兩種驅動方式盡管各有優勢，但也有自身的軟肋。兩者在數控機床上都有各自最佳的適用范圍。
直線電機驅動在以下數控裝備領域具有得天獨厚的優勢：高速、超高速、高加速度和生產批量大、要求定位的運動多、速度大小和方向頻繁變化的場合。例如汽車產業和IT產業的生產線，精密、復雜模具的製造。
大型、超長行程高速加工中心，航空航天製造業中輕合金、薄壁、金屬去除率大的整體構件「鏤空」加工。例如美國CINCI ATI公司的「Hyper Mach」加工中心(46m)；日本MAZAK公司的「HYPERSONIC 1400L超高速加工中心。
要求高動態特性、低速和高速時的隨動性、高靈敏的動態精密定位。例如，以Sodick為代表的新一代高性能CNC電加工機床、CNC超精密機床、新一代CPC曲軸磨床、凸輪磨床、CNC非圓車床等。
輕載、快速特種CNC裝備。例如德國DMG的「DML80 Fine Cutting」激光雕刻、打孔機，比利時LVD公司的「AXEL3015S」激光切割機，MAZAK的「Hyper Cear510」高速激光加工機等。
德國DMG公司以批量生產各類高性能數控裝備著稱，在其伺服進給系統中採用直線電機較早，而且採用率也是很高的(均在機床型號後標注「Linear」)，該公司對兩種驅動方式的配置有三種類型：
各坐標軸全部配置直線電機驅動的「快速型」數控裝備。例如：DMC85V Linear、DMC75V Linear、DMC105V Linear、DMC60H Linear、DMC80H Linear以及DML80-Fine Cutting激光加工機等。
混合驅動型。例如：DMF500 Linear動柱式大型立式加工中心，在X軸(行程5m)配直線電機，V=100m/min；而在Y、Z軸則採用「旋轉伺服電機+滾珠絲杠」，V=60m/min。
各坐標軸全部配置「旋轉伺服電機+滾珠絲杠」的「強力型」加工中心。例如：DMC63H高速卧式加工中心，V=80m/min，加速度1g，定位精度0.008mm。此外還有DMC80H和DMC100H、DMC125H (o BLOCK)以及DMC60T等。
兩種驅動方式在德國DMG公司被同時運用也說明他們具有各自的優勢。直線電機的提升空間很大，未來直線電機的技術更加成熟了、產量上去了、成本下降了，應用也會更加廣泛，但從節能降耗、綠色製造的角度思考，以及兩種結構自身特點考慮「旋轉伺服電機+滾珠絲杠」驅動仍有其廣闊的市場空間。直線電機將成為高速(超高速)、高檔數控裝備中的主流驅動方式的同時，「旋轉伺服電機+滾珠絲杠」依然會繼續保持其在中檔高速數控裝備中的主流地位。

H. 數控加工中心斷刀產生原因及解決方案
斷刀多發生在鑽頭、絲錐、鉸刀，而盤銑刀面加工類幾乎不涉及到斷刀，盤銑刀的真正需求點在磨損。
因此我們要把斷刀和磨損這2個需求點分開來看。大眾、賓士、寶馬、保時捷這種汽車行業大客戶加工汽車發動機缸體缸蓋所使用的加工中心一般都是GROB格勞博，那麼他們用的什麼方法來避免斷刀、刀具磨損？
推薦你了解一下這幾個品牌：德國BK Mikro 比卡米克羅、Artis 馬波斯、MCU德國、Digital Way 法國。
簡答講，如果你只需要解決斷刀，那麼自行網路或者優酷或者QQ視頻去了解BK Mikro；如果你要想監控刀具磨損那麼則去咨詢Artis或者Ditital Way。
說一說實際使用中這些系統存在的問題：①BK Mikro德國，加工中心刀庫內斷刀檢測，GROB格勞博標配的斷刀檢測方案，是的，沒錯，是標配。你去大眾、賓士、寶馬等等生產車間去看，每台都裝了。只要你機械設計沒有問題不幹涉、安裝支架做的好牢靠不亂晃、裝配師傅責任心強裝配正確，它就沒問題。但BK Mikro只負責檢測鑽頭、絲錐類的小直徑刀具不能檢測盤銑刀。②Artis、MCU、Digital Way這三種均屬於叫做主軸功率負載監控系統。標配的最多的是Artis，因為和BK Mikro一樣歷史悠久，所以裝配的相對多。這類主軸負載監控系統，最大的問題就是誤報警。比如：不同供應商發來的同一型號工件，存在工差、軟硬的差別。在高度發達的工業國家，人家各種東西都標准化了，因此發給你的工件毛坯幾家供應商的都差不多。這樣反應到你波形上來也就差別不大。同時還有車間溫度、車間地板水泥厚度抗震能力、等等等。各方面綜合影響，結果就是你波形波動大，導致你上個月生產正常不報警，這個月換批料或者環境發生變化，或者搞不清為什麼，就誤報警了。這個不展開寫，太多了。
