This machine is a hybrid of the 4896 with the same construction and components but on a shorter overall machine size to better fit those tight spots and small working areas but still provide you the same freedom of a larger machine. This system like our larger tables is designed with heavy duty Steel frame construction, Steel Tube Gantry with Plate Steel Uprights, Linear Guide Rails and Bearings, Precision Anti-Backlash center driven ball screws on all axis, high end electronic components, and many other industrial components The 4860 is designed to produce high quality products while only taking 79" x 81" floor space. Again this system works well for crafts, R & D projects, hobbyists at home or the educational system. The ShopSabre 4860 will provide you with years of problem free service and the quality you have come expect from a ShopSabre CNC.
