BST-20,25 is a simple, high precision, easy to learn, cost-effective CNC lathes. Hard to break the traditional disadvantages of rail wear and produce precision change, after linear guide with Taiwan, to achieve the fast and accurate processing operations. Such as car cylindrical, arc, taper, thread and other complex machining, especially after the installation of movable type synchronous guide bush, to achieve mass production of various types of elongate shaft. As various instruments, meters, electronic products connectors, eyeglasses, watches, micro-motor components. Can also be more complex secondary processing according to the customer selection and modification.
