    石材雕刻機應用范疇

    更新時間:2018-01-19 點擊數:

    在數控機床中,電主軸一般選用變頻調速辦法。主要有一般變頻驅動和操控、矢量操控驅動器的驅動和操控以及直接轉矩操控三種操控方法。一般變頻為標量驅動和操控,其驅動操控特性為恒轉矩驅動,輸出功率和轉速成正比。一般變頻操控的動態功用不行抱負,在低速時操控功用欠安,輸出功率不行安穩,也不具備C軸功用。但價格廉價、結構簡單,一般用于磨床和一般的高速銑床等。矢量操控技能仿照直流電動機的操控,以轉子磁場定向,用矢量改換的辦法來完成驅動和操控,具有杰出的動態功用。矢量操控驅動器在剛發動時具有很大的轉矩值,加之電主軸本身結構簡單,慣性很小,故發動加速度大,能夠完成發動后瞬時到達答應極限速度。這種驅動器又有開環和閉環兩種,后者能夠完成方位和速度的反饋,不只具有更好的動態功用,還能夠完成C軸功用;而前者動態功用稍差,也不具備C軸功用,但價格較為廉價。直接轉矩操控是繼矢量操控技能之后發展起來的又一種新式的高功用溝通調速技能,其操控思想新穎,系統結構簡潔明了,更適合于高速電主軸的驅動,更能滿意高速電主軸高轉速、寬調速范圍、高速瞬間準停的動態特性和靜態特性的要求,已成為溝通傳動領域的一個熱點技能。適用范圍:花崗巖、大理石、青石、砂巖等石材雕琢花崗巖等硬質石材能夠分層次雕琢至5mm

    In CNC machine tools, motorized spindle frequency control method is generally used. There are three kinds of control methods, which are general frequency conversion drive and control, vector control driver drive and control, and direct torque control. General frequency conversion is scalar drive and control, its driving control characteristic is constant torque drive, output power and speed is proportional to. Dynamic function no ambition general frequency conversion control, speed control function not beautiful, not stable output power, also does not have the function of C axis. But the price is cheap, simple structure, generally used in grinding machines and general high-speed milling machine, etc.. The vector control skill imitates the DC motor's control, uses the rotor magnetic field direction, uses the vector change method to complete the actuation and the control, has the outstanding dynamic function. The vector control driver has a large torque value when it is started, and the electric spindle itself is simple and the inertia is very small, so the acceleration is large, and the speed limit can be reached immediately after the start. The driver has two kinds of open loop and closed loop, the latter can complete the feedback of azimuth and speed, not only has better dynamic function, but also can complete the function of C axis; and the former dynamic function is slightly worse, also does not have the C axis function, but the price is cheaper. Direct torque control is after vector control skills developed and a new high power communication speed skills, the manipulation of new idea, concise system structure, driving more suitable for high-speed electric spindle, dynamic characteristics can satisfy the high-speed spindle of high speed, wide speed range, high speed and accurate stop moment the static characteristic, has become a hot field of transmission communication skills. Scope of application: granite, marble, bluestone, sandstone and other stone, carved granite and other hard stones, can be carved to 5mm layers
