Hello, I'm from Spain and I'm new in this forum, sorry for my english, I'm going to explain my case.
I'm building my own cnc machine, I have a THK Linear actuator KR30H-300-D, you can see it in page 11 :
http://www.thk.com/documents/us_pdf/...t/en_B_263.pdf
I want to use it in the Z axis, it has a ballscrew and a guide block integrated in the actuator body, but I don't know if the guides integrated are enough to do the work in my machine, I can put aditional guides and use the THK actuator it like a simple ballscrew, but it will be better if I can use it without aditional guides and trust in the rigidity an accuracy of the THK actuator to do the work.
I want to use my CNC machine to mill wood, plastics and in some cases aluminium.
Thanks in advance.
