- Lathe with two stepper motors fitted to stepper motor mounts on the leadscrew and crosslide axes (The tailstock spindle remains manually controlled)
- A computer with Ubuntu Linux-based OS with LinuXCNC 4-axis CNC software preinstalled
- Keyboard and mouse
- 4-axis driver board and power supply installed inside the computer
- Instruction and utility CD. The CD includes complete instructions, and several free utilities to translate CAD files or TrueType fonts into G-code.
- A blank 4GB USB flash drive is also included
- 1-year warranty on all components for non-production use. 90-day warranty on CNC and computer-related components.
You supply only a monitor.
- A powerful 90V DC motor with an electronic speed controller
- 2.75″ (70 mm) x 6.0″ (152 mm) crosslide
- 24″ (610 mm) steel bed that has 17″ (431 mm) between centers
- 2.5″ (63 mm) resettable “zero” handwheel on the leadscrew, a 2″ (51 mm) resettable “zero” handwheel on the crosslide feed screw, and a 2″ (51mm) resettable “zero” handwheel on the tailstock. Each handwheel has laser engraved aluminum handwheel collars
- Rocker tool post (P/N 3057) substituted for the standard tool post used on the short-bed lathes
- Pulleys, drive belt, faceplate, lathe dog, two dead centers, three hexagonal keys, tool post, sharpened high-speed steel cutting tool, eight-foot three-wire power cord, and instruction manual
NOTE: The instructions that accompany Sherline CNC systems are written primarily for use with a mill, but due to a number of requests, we have made the system available for lathe users as well. The primary consideration when using the system with a lathe is to keep in mind that movement of a tool on the crosslide axis removes material from the RADIUS of the part, resulting in two times that amount being removed from the DIAMETER.
Always wear safety glasses when operating machine tools.
