·16mm Big Diamater Ball Screw | ![]() | |
16mm Big Diamater Precise Ball ScrewIf you have experienced whipping and wobbling issues with 8mm or thin diamater lead screws on workbee and other machines, you will know how important a large diameter ball screw can be for machines with long travel. Thin Ball screw can result in reduced straightness and insufficient concentricity, resulting in distorted motion, which in turn results in a loss of accuracy. The large diameter of 16mm not only avoids whipping and shaking, but also solves the problem of sagging caused by the slender screw,Further improve the running accuracy, working accuracy, repeatability and positioning accuracy of the machine!Especially for long travel machines such as 1500mm and longer. |
·Best Match for Torque&Load&Motor |
| |
According to YUYONG Tech Dept‘s testing,the motor type is nothing to do Ball screw Diamater! If the torque is enough, it will support any big diamater Ball Screw! The Ball Screw Diamater is nothing to do with Accuracy! According to Principles of Physics: T=(PF*I)/2π T:Drive Torque N.m P: Ball Screw Lead m I:Ball screw drive efficiency,generally 90-94% Hypothetical conditions:Horizontal load 100kg, 1610 Ball Screw,friction coefficient μ=0.1,then the drive torque T=0.01x100x0.9/6.28=1.43NM. Generally take 1.5 times the driving torque,then it's 2.2N.M, no matter stepper motors 2.45N.m or Close Loop Motors 3.6N.m, all can meet the needs. That means With sufficient torque,the ball screw diamater never affect Torque,There is no such thing as a so called which diamater ball screw is best for Nema23 motors! 16mm is the most commonly used ball screw machine, even the smallest machines such as 3040, 6090 are using 16mm instead of 12mm! So for long Travel Machine such as 1500mm or longer,16mm is best option! Below 16mm is just for DIY machines,This is one of the reasons why the queenant can be used as a quasi-industrial machine! |
·2 Linear Rails+4 Linear Blocks on each axis | ![]() | |
Please don't be deceived by some company's advertisement, No matter QueenBee or other machines, they all use 2 linear rails+4 Blocks. Our QueenAnt machine each axis all use 2 rails+4 Blocks, Especially the Y and A aixs, they load entire X axis and Z axis, much higher loads than the X-axis,but the X axis has been used 2 rails+4 Blocks, Y and Axis should use 2 rails+4 Blocks more! Please always believe that the double rails have better load capacity, balance, stability and anti-vibration than the single rail. |
·12mm Thickened and Super Flat Aluminum Luxury Plates |
| |
For the first time, queenant uses an ultra-thick 12mm aluminum plate to prevent deformation in any direction, which greatly improves the overall rigidity, flatness and stability!
|
·Super Enhanced X & Z V2 | ![]() | |
Customers have been suffering from Flexing of the X-axis for a long time when working with 2.2KW or heavier spindles.And this is obvious when the spindle is working on harder materials and longer X-axis of machines.The torsional force of the spindle causes the X-axis to twist and cause displacement of the workpiece, resulting in a loss of accuracy. |
·X&Z Balance Force | ![]() | |
In previous CNC machines, the whole Z axis with spindle attach to X plate,this causes the X-axis to only be stressed on one side, and when a 2.2KW or heavier spindle is attached, it may cause vibrations when the spindle is working, which will also cause loss of accuracy and flexing of the X-axis. |
·Longer and Strength Z Axis | ![]() | |
Use Longer 340mm Z Axis Length to replace original 250mm,also use stronger HGR15 Linear Rail and Blocks to replace original smaller MGN15 Rails and Blocks.Greatly increases strength and stability! |
·Filled 2040V-slot in the gap of 4080 | ![]() | |
With the new in-line bottom design allows all Y and A axes to be supported, which avoids twisting in the Y&A direction, and the movement is more linear and smoother! |
·Brand new bottom support for Y&A axis | ![]() | |
With the new in-line bottom design allows all Y and A axes to be supported, which avoids twisting in the Y&A direction, and the movement is more linear and smoother! |
