一、實(shí)際案例：在一些高精度模具加工中，對(duì)數(shù)控機(jī)床的定位精度要求極高。如果導(dǎo)軌絲杠的精度不夠，可能會(huì)導(dǎo)致模具的尺寸偏差超出允許范圍，影響模具的裝配和使用性能。例如，在加工手機(jī)外殼模具時(shí)，要求加工精度達(dá)到 ±0.01mm，如果絲杠的定位精度不能滿足要求，就會(huì)導(dǎo)致手機(jī)外殼的尺寸不一致，影響手機(jī)的裝配質(zhì)量。

　　1、 Practical case: In some high-precision mold processing, the positioning accuracy of CNC machine tools is extremely high. If the accuracy of the guide screw is not sufficient, it may cause the dimensional deviation of the mold to exceed the allowable range, affecting the assembly and performance of the mold. For example, when processing mobile phone casing molds, it is required to achieve a machining accuracy of ± 0.01mm. If the positioning accuracy of the screw cannot meet the requirements, it will lead to inconsistent dimensions of the mobile phone casing, affecting the assembly quality of the mobile phone.

　　二、機(jī)器人系統(tǒng)

　　2、 Robot system

　　影響機(jī)制：機(jī)器人在工業(yè)生產(chǎn)、醫(yī)療衛(wèi)生、科學(xué)研究等領(lǐng)域得到了廣泛應(yīng)用。機(jī)器人的定位精度直接影響其工作性能和可靠性。導(dǎo)軌絲杠在機(jī)器人關(guān)節(jié)中起到傳遞動(dòng)力和實(shí)現(xiàn)精確運(yùn)動(dòng)的作用。如果導(dǎo)軌絲杠的精度不高，會(huì)導(dǎo)致機(jī)器人的運(yùn)動(dòng)誤差增大，影響其定位精度和重復(fù)定位精度。例如，在工業(yè)機(jī)器人中，絲杠的反向間隙、摩擦等因素會(huì)影響機(jī)器人的運(yùn)動(dòng)精度，從而影響其對(duì)工件的抓取和裝配精度。此外，導(dǎo)軌的剛性和精度也會(huì)影響機(jī)器人的運(yùn)動(dòng)穩(wěn)定性，進(jìn)而影響其定位精度。

　　Impact mechanism: Robots have been widely used in industrial production, medical and health care, scientific research and other fields. The positioning accuracy of robots directly affects their performance and reliability. The guide screw plays a role in transmitting power and achieving precise motion in robot joints. If the precision of the guide screw is not high, it will lead to an increase in the motion error of the robot, affecting its positioning accuracy and repeat positioning accuracy. For example, in industrial robots, factors such as reverse clearance and friction of the screw can affect the robot's motion accuracy, thereby affecting its grasping and assembly accuracy of workpieces. In addition, the rigidity and accuracy of the guide rail can also affect the motion stability of the robot, thereby affecting its positioning accuracy.

　　實(shí)際案例：在醫(yī)療機(jī)器人領(lǐng)域，如微創(chuàng)手術(shù)機(jī)器人，對(duì)定位精度的要求非常高。如果導(dǎo)軌絲杠的精度不夠，可能會(huì)導(dǎo)致手術(shù)器械的位置偏差，增加手術(shù)風(fēng)險(xiǎn)。例如，在進(jìn)行腦部微創(chuàng)手術(shù)時(shí)，要求手術(shù)器械的定位精度達(dá)到 ±0.1mm，如果絲杠的定位精度不能滿足要求，就會(huì)影響手術(shù)的性和有效性。

　　Actual case: In the field of medical robots, such as minimally invasive surgical robots, the requirements for positioning accuracy are very high. If the accuracy of the guide screw is not sufficient, it may cause positional deviation of surgical instruments and increase surgical risks. For example, in minimally invasive brain surgery, the positioning accuracy of surgical instruments is required to reach ± 0.1mm. If the positioning accuracy of the screw cannot meet the requirements, it will affect the safety and effectiveness of the surgery.

　　三、半導(dǎo)體制造設(shè)備

　　3、 Semiconductor manufacturing equipment

　　影響機(jī)制：半導(dǎo)體制造設(shè)備對(duì)精度的要求極高，因?yàn)榘雽?dǎo)體芯片的制造過程需要在納米尺度上進(jìn)行精確控制。導(dǎo)軌絲杠在半導(dǎo)體制造設(shè)備中用于實(shí)現(xiàn)晶圓的精確移動(dòng)和定位。如果導(dǎo)軌絲杠的精度不高，會(huì)導(dǎo)致晶圓的位置偏差，影響芯片的制造精度。例如，在光刻機(jī)中，絲杠的定位精度直接影響光刻機(jī)的套刻精度，從而影響芯片的制造質(zhì)量。此外，導(dǎo)軌的精度和穩(wěn)定性也會(huì)影響晶圓的運(yùn)動(dòng)平穩(wěn)性，進(jìn)而影響芯片的制造精度。

　　Impact mechanism: Semiconductor manufacturing equipment requires extremely high precision, as the manufacturing process of semiconductor chips requires precise control at the nanoscale. The guide screw is used in semiconductor manufacturing equipment to achieve precise movement and positioning of wafers. If the precision of the guide screw is not high, it will cause positional deviation of the wafer, affecting the manufacturing accuracy of the chip. For example, in a lithography machine, the positioning accuracy of the screw directly affects the etching accuracy of the lithography machine, thereby affecting the manufacturing quality of the chip. In addition, the accuracy and stability of the guide rail will also affect the smoothness of wafer movement, thereby affecting the manufacturing accuracy of the chip.

　　實(shí)際案例：在半導(dǎo)體制造過程中，光刻機(jī)是關(guān)鍵設(shè)備之一。光刻機(jī)的套刻精度要求達(dá)到幾納米甚更高，如果絲杠的定位精度不能滿足要求，就會(huì)導(dǎo)致芯片的圖案重疊不準(zhǔn)確，影響芯片的性能。例如，在制造高端芯片時(shí)，要求光刻機(jī)的套刻精度達(dá)到 ±1nm，如果絲杠的定位精度不能滿足要求，就會(huì)影響芯片的制造質(zhì)量和良品率。

　　Practical case: In the semiconductor manufacturing process, lithography machine is one of the key equipment. The etching accuracy of the lithography machine is required to reach several nanometers or even higher. If the positioning accuracy of the screw cannot meet the requirements, it will lead to inaccurate pattern overlap of the chip, affecting the performance of the chip. For example, when manufacturing high-end chips, it is required that the lithography accuracy of the lithography machine reach ± 1nm. If the positioning accuracy of the screw cannot meet the requirements, it will affect the manufacturing quality and yield of the chip.

　　四、精密測量儀器

　　影響機(jī)制：精密測量儀器用于測量各種物理量的精確值，其定位精度直接影響測量結(jié)果的準(zhǔn)確性。導(dǎo)軌絲杠在精密測量儀器中用于實(shí)現(xiàn)測量探頭的精確移動(dòng)和定位。如果導(dǎo)軌絲杠的精度不高，會(huì)導(dǎo)致測量探頭的位置偏差，影響測量結(jié)果的準(zhǔn)確性。例如，在三坐標(biāo)測量儀中，絲杠的定位精度直接影響測量點(diǎn)的坐標(biāo)值，從而影響測量結(jié)果的準(zhǔn)確性。此外，導(dǎo)軌的精度和穩(wěn)定性也會(huì)影響測量探頭的運(yùn)動(dòng)平穩(wěn)性，進(jìn)而影響測量結(jié)果的準(zhǔn)確性。

　　Impact mechanism: Precision measuring instruments are used to measure the precise values of various physical quantities, and their positioning accuracy directly affects the accuracy of measurement results. The guide screw is used in precision measuring instruments to achieve precise movement and positioning of the measuring probe. If the precision of the guide screw is not high, it will cause positional deviation of the measuring probe, affecting the accuracy of the measurement results. For example, in a coordinate measuring instrument, the positioning accuracy of the lead screw directly affects the coordinate values of the measurement points, thereby affecting the accuracy of the measurement results. In addition, the accuracy and stability of the guide rail will also affect the smoothness of the measurement probe's movement, thereby affecting the accuracy of the measurement results.

　　實(shí)際案例：在航空航天領(lǐng)域，對(duì)零件的尺寸精度要求非常高，需要使用精密測量儀器進(jìn)行檢測。如果導(dǎo)軌絲杠的精度不夠，可能會(huì)導(dǎo)致測量結(jié)果的偏差，影響零件的質(zhì)量判斷。例如，在測量飛機(jī)發(fā)動(dòng)機(jī)葉片的尺寸時(shí)，要求測量精度達(dá)到 ±0.005mm，如果絲杠的定位精度不能滿足要求，就會(huì)影響測量結(jié)果的準(zhǔn)確性，從而影響發(fā)動(dòng)機(jī)的性能和可靠性。

　　Practical case: In the aerospace field, there is a very high requirement for the dimensional accuracy of parts, which requires the use of precision measuring instruments for testing. If the accuracy of the guide screw is not sufficient, it may lead to measurement deviation and affect the quality judgment of the parts. For example, when measuring the size of aircraft engine blades, a measurement accuracy of ± 0.005mm is required. If the positioning accuracy of the screw cannot meet the requirements, it will affect the accuracy of the measurement results, thereby affecting the performance and reliability of the engine.
