SHERLINE 4000/4400 CNC HORIZONTAL MACHINING CENTER

Technical Description

The Sherline 4000/4400 CNC horizontal machining center is a compact precision lathe designed for small-scale prototyping and detailed machining operations. Featuring a single main spindle with a maximum turning length of 8 inches (expandable to 16 inches with optional extended bed) and a 3.5-inch maximum swing diameter over the bed, this machine accommodates workpieces up to 3 inches in chuck diameter. The spindle operates at continuously variable speeds from 70 to 2,800 RPM with 0.30 horsepower, enabling electronic speed control without manual belt changes. The machine incorporates a 2-axis CNC control system with 4.25 inches of X-axis travel and 8 inches of Z-axis travel, utilizing a slide-type primary tool carrier that accommodates one cutting tool at a time. The system includes stepper motors on both axes with 6.5-amp drivers powered by 24-volt supply, running on Linux OS with EMC2 software for intuitive 4-axis capability when optional accessories are added. The 24-inch steel bed features a 17-inch between-centers capacity with resettable zero handwheels on the crosslide for precise positioning and repeatability. This CNC-ready configuration includes pre-wired components and a computer with 2 GHz processor, 4GB RAM, and 250GB hard drive, making it an ideal solution for hobby users, educational institutions, and small production environments requiring versatile horizontal machining capabilities.
