【導(dǎo)讀】不妥之處，因此僅供單螺桿壓縮機生產(chǎn)廠參考。機床是一個國家制造業(yè)水平高低的象征，其核心就是數(shù)控系統(tǒng)。是買日本的，我們自產(chǎn)的滾珠絲杠、軸承在精度、壽命方面都有問題。目前國內(nèi)的各大機床。國西門子的系統(tǒng)，但比較少。早期，德國系統(tǒng)不太能適合。我們的電網(wǎng)，我們的電網(wǎng)穩(wěn)定性不夠，西門子系統(tǒng)的電子伺服模塊容易燒壞。他們的系統(tǒng)就燒不壞。近來西門子系統(tǒng)改進了不少，價格方面還是略高。德國人很不重視中。國，所以他們的系統(tǒng)漢語化最近才有，不像日本，老早就有漢語化版的。韓國、臺灣的數(shù)控機床制造能力比大陸地區(qū)略強，不過水平差不多。統(tǒng)，但進口到中國的機床，應(yīng)我們的要求，也換成了日本系統(tǒng)。大宇目前在我國設(shè)有合資企業(yè)。體一樣，自己造機械部分，系統(tǒng)采購日本的。臺灣最主要的幾家機床廠已打算把工廠遷往大陸，稱“智能化、網(wǎng)絡(luò)化”工廠，和世界同步。目前，國家制定了一些政策，鼓勵國民使用國產(chǎn)數(shù)控機床，各廠家也在努力追趕。

　　

【正文】 e electromagic clutch, the tool does not only into the rotation with the vertical shaft to the sport. The advantages of this control method are: the depth of the spiral groove screw tolerance control more accurate, because of several significant table shows the depth of processing, or want a few laps and the depth of processing or circle the number of operations is also very intuitive and userfriendly. Disadvantage are: electrical control of machine tools at the same time more plex parts of this control method at the processing plant, if a sudden power failure, the prior data set will be lost. If you add in the electrical control of the battery to power at the earlydimensional detection devices to maintain the job, the problem can be resolved. Four, the control gear drive space Single screw machine screw in the processing, due to the spiral groove in the rotary tool and the workpiece rotation to plete the synthesis process. Just cut into the workpiece when the tool in the tangential direction of rotation has been going on a greater resistance knife, cutting tool at the workpiece to be cut when the role of the spiral groove, the tool in the tangential direction of rotation has been going up against a smaller knife and even by the spiral groove thrust workpiece. Because there is a boxhole processing machine tool, gear and other processing error, the tool axis of rotation of the drive space is too large, large amount of socalled open. Detect drive way too much space is a fixed power input shaft and output shaft rotation shaking, in the case of the transmission structure of conventional design and manufacture of machine tools, the transmission output shaft angle space at more than ten degrees to the dozens of degrees. Transmission gap caused by too large spiral screw groove surface then there is obvious marks, thus affecting the machining accuracy of the screw. Upon pletion of the assembly machine tool axis of rotation of the drive space is too large, in fact are subject to various errors gear, creating a backlash of the gear is too large. Machine tools in the mechanical transmission gear are used regardless of the accuracy of a few of the class, the designers take into account the gear manufacturing error, processing error box center distance, temperature, lubricating oil film thickness, the assembly error and other factors, machine design must ensure that transmission gear A certain amount of backlash, backlash decide the size of the gear tooth thickness tolerance size. Singlescrew machine has the Main Drive from other machine tool structure specificity. In order to reduce transmission or reasonable gap singlescrew machine tools currently used by the following two ways. The first is: the installation at the output shaft brake Tool at the output shaft rotating the location of cylindrical symmetry with radial brake, brake stand up to the tool frontend of the cylindrical rotary output shaft, brake for spring preload. The working principle of the brake is generated by the friction brake to increase the output shaft damping, reducing the sensitivity of the rotation axis. Are: brake and easy does not change the structure of the original machine tool structure, the method of indirect reduction to achieve the purpose of drive space, in practical applications there is a certain effect. One disadvantage: the prespring brake tool because of the cylindrical output shaft to exert a greater radial force, in fact increases the load machine torque, resulting in increased motor power at the same time gears, bearings to accelerate wear and tear. Disadvantage 2: prespring brake because of the output shaft of the cylindrical tool to exert a greater radial force on the possible geometry of the tool output shaft a negative impact on accuracy. Conclusion: This article describes four areas from existing singlescrew machine layout and structure, and put out the advantages and disadvantages of the list, because of the pressor plant singlescrew machine tools and machine tool external Security information, the above introduction there is inevitably onesided and wrong, and are therefore singlescrew pressor for the production of reference works.
