♦ GMT XY-TABLE divided into : ©Precise level(P) : Ball screw shaft is C5 level, linear slide block is precise level (heavy preload). Application : Measure device, instrument, painting equipment. ©Regular level(R) : Ball screw shaft is R level, linear slide block is high level H (light preload). Application : Woodworking machine * Cutting machine - LCR carving machine * Video Comparactor. GMT linear Slide table base is made by high strength aluminum alloy,has been stress eliminated and cryogenic treatment under 196°C(Please refer to P.42), such quality may maintain high precision still after...

Accuracy Test Accumulated read error(Positioning Accuracy) From datum, move in direction, same interval positioning gradually in the range table could move and note down each real position value (measured from datum to the stop point), and command value( the expected value position in theory after commanding). The maximum differnce is called Accumlated reading error. (Positioning Accuracy) This could be revised by controller. Straightness (XY axis direction ) Positioning on the table(with Glass measuring by electric gauge in the range table could move. Connect two spots from starting point...

Accuracy Test Backlash clearance Use gravity of table or center in moving range as datum, and put a specified load on it in the same transmission direct as moving forward to datum. Difference between basis and unloaded position after unloading is called Backlash clearance. Parallel value B in XY action Parallel value comes from XY act and plane(XY positioning table intallation plane). (Gauge fixed and immovable) Fix gauge in the center of table stroke, and have sticks of gauge against installation plane of table. Test the table in full stroke of moving in X direction and Y direction, and...

Limited element analysis GMT XY-TABLE products use limited elements analysis software in application on construction and shape for optimized design. ♦ Points to optimized design are as below = 1. Reduce materials used in parts production, and decrease manufacture and transportation cost at the same time. 2. Due to material reduction, also decrease down entire weight of product greatly ; in opposite, energy loss dropped down by product weight decrease, but system efficiency raised. Meanwhile environment protection is also reached. 3. Decrease stress » increase construction strength. 4. Shape...

Stepping motor & Servo motor ♦ Stepping motorand DC servo motor Stepping motor and DC servo motor are usually used as power source to drive the positioning table. Each one has its feature for selection up on application needs. AC servo motor is also brushless DC motor with similar character as DC servo motor.

To judge linear rail guide model fit or not by these results. Checking computation of load capacity is to get static safety factor by basic rated static load(Co), and also ensure static load limit; checking computation of life is to calculate rated life by basic rated dynamic load. Life of linear rail guide means grand distance accumulated of circulatory stress effect brought from balls or rolling plane till peeling off from metal surface caused by rolling fatigue of material. Basic static load Co The contact area in between balls with rolling plane on linear rail guide would appear partial...

Load of linear rail could be taken by calculation, but calculated value is less than load in actual running with vibration and shock. Considering different running conditions and speed, it's recommended to take experienced load factor divided by basic dynamic load.

Advantages of cryogenic process All GMT XY-TABLE is well been cryogenic processing. Cryogenic process is to place the part in the medium with temperature under 196°C, followed step by step progress of new technic to improve material character. Found by relevant search, cryogenic process is not only obviously increase on strength and life of black (colour)metal, plastic and china---etc, but also improve the structure evenly. Increase of dimension stability brings huge economic benefit and promising application in aviation - aerospace » optics » creatures - chemistry » machinery, electronic...
