Sherline Industrial CNC Chucker Lathe with Driver Box 6620

Industrial CNC Chucker Lathe with Driver Box – PRICE WILL VARY BASED ON OPTIONS, WE WILL EMAIL OR CALL YOU WITH SPECIFIC AND FINAL PRICE.

Sherline designed their CNC chucker lathe for their industrial customers who want the convenience of using multiple tools in a single set-up. The lathe has a 13″ crosslide that accommodates the 3/8″ gang-tooling tool post and two, optional tool posts that can be used for boring and parting tools (tools not included).

Standard Features Of Chucker Lathe Include

Ball Lead Screw: Rolled Ball Screw with BSH Nut .10mm Diameter, 2mm Lead. C7 Accuracy, P1 Preload. The linear accuracy is 50 micrometers/300mm
3/8″ Gang-tooling tool post, which holds up to four tools
14″ Base
13″ Mill table
Mill Saddle: Has electroless nickel coating with Teflon. This offers a hard surface that is rust proof. The Teflon offers a friction coefficient of .1-.2u for smoother movement of the saddle and the table.
3C Collet headstock: TIR (total indicator runout) is rated at .0005, or less on the 3C headstock. In addition, the 3C spindle is electroless nickel plated to aid in rust prevention, and to increase the surface hardness of the spindle for durability.
Powerful 90V DC motor with electronic speed controller
Two, 2-amp high-torque stepper motors
Accordion way cover and brass-tube leadscrew cover
Maximum feed rate is 32 in/min.
Largest diameter through the collet is ½” (13mm). NOTE: collets are not available through Sherline Products.

Included Components

Driver box (Converts g-code to steps to run DC stepper motors)
Output cables for X, Y, Z and A pre-wired with DIN plugs for stepper motors
3.7 amp, 24 volt power supply with cord, works on 115 or 240 VAC
25-pin parallel cable*
2 CD set with Linux/EMC2, utilities and instructions
Two spare fuses

NOTE: A 25-wire parallel port is required because EMC2 is designed to be capable of running up to six axes simultaneously. Even though the Sherline driver box only uses four of those axes at one time, a 2-wire serial USB port cannot transmit data to multiple axes fast enough for glitch-free CNC operation.

Minimum Computer Requirements

In order to install and run a Linux based system from the disc provided it is recommended the computer have at least the following minimum specifications:

Processor speed: 800 MHz or faster (Pentium III class or equivalent processor)
RAM: 512 Mb (Sherline provides 1 Gb)
Hard Drive: 20 Gb or larger
25-pin parallel port (printer port)
(Laptop computers are not recommended.)
