I cant excuse his behaviour toward you, and i find it extremely unlikely, because i have been dealing with leadshine directly for over ten years and never had any issues.
However we are a...

The C grade is only the lead accuracy and this pdf will show you what they refer to.

We stock Comtop ballscrews and hiwin rails.
I think Comtop only resell the Abba rails.
We used to stock the Abba Rails but moved to Hiwin nearly two years ago, not due to quality, but due to long...

As said, i made some assumptions.
1) the root diameter.
2) fixing method.

The root diameter is the smallest diameter on the actual screw and 10mm lead ballscrews of this size normally have large...

I have attached the calculations needed to work out the critical speeds, but you may find it easier to use this web link.

Then you will need either a larger diameter ballscrew or one with a higher lead.

The critical speed is about 400 RPM.
the motor you are using is too small.

A servo will lock the shaft if there is no clock and direction signal being sent to the driver as long as the driver is enabled.

The critical speed of a 25mm ball screw at 2100mm long is about 630 RPM.
This is presuming the root diameter is 23mm.
Also this is when using a fixed and floating end ball screw supports (BK and...

The 2M2280N is suitable for a wide range of stepping motors and is ideal for our SY85 range. The 2M2280N is best suited for applications that requires a very high motor speed while maintaining smooth...

The 2M880N is suitable for a wide range of stepping motors including our SY57 and SY85 and is ideal for any application that requires a High performance but very low cost...

We have just added a new range AC servo motors and drivers.
They are ideal for CNC machines, and accept clock and direction so are compatible with Mach 3 and other CNC control software.

We stock...

We have just introduced a new range of industrial spindle motors.
The ES range are TEFC (Totally enclosed Fan Cooled) and are avalable from 120W up to 5.5KW and a max speed of 48000 RPM.

That is the locking nut and only holds the ball screw in the support, the bearings are held in with the square plate that is secured with 4 socket head screws, and you can see in the picture on the...

Thanks for picking that up.

For proper servicing grease needs to be injected between the two bearings so it goes into both bearings.
The Q option (Grease nipple) does not cost that much more, so if ease of servicing is...

The BK comes with a seal on front and back so this will stop dirt getting into the bearing.
Generally they don’t need a lot of servicing, but if you application is particually demanding the BK is...

Only the mounting on the ball nut.
The FSI has four holes and the FSU has six.

There is no point adding a 2:1 ratio then doubling the lead of the screw, this will infact give you less thrust than going direct and having a 5mm lead on the screw.
If we work on 2.3Nm of torque at...

Why do you need such large diameter ball screws?
Also what motors are you thinking of using? you say 25kgf motors, but kgf is not a measure of torque, do you mean kg-cm?
If you mean 25Kg-cm, then...

Stepper drivers that have a USB, RS232 or RS485/422 would normally have an onboard motion controller.
these controllers with have their own propiatary programing language and unless i have missed...

Just use an isolating transforma that goes from 230V to 110V AC.
If you put 230V into this driver the motor will fry, and any AC spikes will pop the driver.
Even at 110V the motor will still get...

Gecko drivers suffer just like all the other drivers on the market.
Microstepping is not linear because it is open loop. so you can only rely on the full step position as an accurate and repeatable...

Its not that it cant be done, it is that your supplier does not want to.
they should have no problem getting that part from Isel.

Watts is power and Oz inch is torque.
Most servos outside of the US will list the torque as Nm.

It is hard to say without having the details of the motor, but if we presume that the motor is similar to the motors we sell, then at 600 RPM you will get about 2nm, so this works out to be 125W @600...

While the theoretical resolution of a stepper is 2000 steps per rev running at ten steps per step, it is infact not a good comparison.
First off, a stepper motor is not linear between the full step...

if the current is only half what the motors need then you will only get half the torque so that would make a differnence.

20-30 inch a minute? What is this in RPM of the motor? what is the lead of the screw?
