Detailed Product Description

Hollow Shaft or threaded shaft stepper motor for Linear Actuator

Nema11, Nema14, Nema17, Nema23 and Nema34

Bespoke ball screw

•Hollow Shaft or threaded shaft step motor
•Nema8, Nema11, Nema14, Nema17, Nema23 and Nema34
•Bespoke or ground leadscrew •POM nut, brass or anti-backlash nuts
•Normal treatment Trapezoidal, Acme standard Leadscrew or Teflon Coating for longer life time and smooth linear motion
•Customized length and resolution, leadscrew diameters.

These kind of linear stepper motor or step motor linear actuator have a hollow shaft or threaded shaft, which allows them to be used as a linear actuator with Bespoke Leadscrew or Ground Leadscrew. Brass nut, POM nut or Anti-backlash Nuts. Stainless Steel Acme standard Trapezoidal Leadscrew with normal treatment or Telfon Coating treatment for anti-corrosion or special long run and smooth applications. As the motor runs, it moves along the leadscrew or ballscrew at a specific rate of 1cm per 5 or so full rotations. These are a good choice for linear motion where precision and repeatability are important.

Q:Is the grease of the machine tool screw rod good or weak?: With thick and thin does not matter, mainly with high speed high temperature grease.

Q:CNC machine tool screw gap: The gap is normal

Q:I'd like to make my own lathe screw. What material should I use?: The ordinary lathe screw is only the general precision grade, and the requirement of the abrasion resistance and the material deformation is not particularly high. So use 45# or 40Cr conditioning.If it is a precision machine tool, such as a rib grinder or an ultra long connecting screw, it requires a high resistance to wear, a small amount of deformation, and can maintain the accuracy for a long time. Use 9Mn2V or CrWMn quenching.

Q:How about the central screw in the CNC lathe? Or an ordinary side screw!: Structurally, the center screw must be stable. Without doubt.To tell the truth, NC cars are too many brands, and not so good brand, it is better to see its quality can not do.The lathe is good. Look at the key points. Spindle, wire guide, motor, and the work of its own bed.Table spindle, guide rail, screw rod, motor, high performance price ratio.Japanese spindle, wire rod, guide rail and motor are of good quality, but they are expensive. (people do things too much consideration of the cost, resulting in quality can not keep up. Hey

Q:What material is used for the screw nut of machine tools?: As the screw rod 1 to compressive strength and fatigue resistance enough 2 has certain plasticity and toughness, low coefficient of friction and good running in 3 has good thermal conductivity, thermal expansion coefficient and corrosion resistance of low alloy, sliding bearing

Q:How can the accuracy of the CNC machine tools be compensated after a few years?: The gap clearance of the screw bar is adjusted on the parameter. The old version of FANUC is 535 refers to the X axis, and the 536 refers to the Z axis, and the new version is 1851, and the inside is divided into the X/Z axis

Q:I would like to ask what method installed, do not know how many balls, loaded and loaded less, what is the situation, ah, urgent, thank you: [method for installation of ball screws]The ball screw nut pair is only used to bear axial load, the radial force and bending moment will cause the ball screw nut pair additional surface contact stress and other loads, which may lead to permanent damage to the lead screw. Proper installation is the prerequisite for effective maintenance. Therefore, the ball screwWhen the nut is attached to the machine, attention should be paid to the following points:The axis of the screw must be parallel to the axis of the supporting rail. The bearing block and the nut seat at both ends of the machine must be in line at three.Install the nut as close as possible to the support bearing.Install the supporting bearing as close as possible to the nut installation site.When the ball screw is installed on the machine, please do not remove the nut from the lead screw.If you have to remove the use of auxiliary sleeve, or loading and unloading of the ball may fall off. The following points should be noted when handling nuts:The outer diameter of the auxiliary sleeve should be less than the bottom diameter of the screw 0.1-0.2mm.Auxiliary cover in use, must rely on tight screw, screw shaft shoulder.The uninstall, can not be too large, so as not to damage the nut.When loading the installation hole, avoid impact and eccentricity.

Q:The Z shaft screw is close to the motor and is equipped with 3 angular contact bearings. There are 2 bearings under it. Ask experts to teach me how to install, the top 3 how to arrange, the following 2 how to arrange, thank you!: The following 2 bearings are back to back, but the top one is on the opposite side and the two is on the opposite!!

We hope to develop new ideas and new realms in the field of robotic research and manufacturing, making our robot products as ubiquitous as home computers, and similarly playing an active role in the daily life of ordinary people.
