Product Description
Upgraded DRO Chip
Beginning August 1st, 2021, all DROs will ship with an upgraded chip. This new chip upgrade allows our Digital Readout to function with our ball screw machines as well as our standard leadscrew machines. We also programmed some upgrades based on customer feedback, like using Metric on Inch machines and using Inch on Metric machines.
The new DRO chip has six different modes to choose from based on the machine type, e.g., mill, lathe, leadscrew, or ball screw, and your preference of either inch or metric display on the DRO.
For more detailed information on setting up the modes for DRO, please see the DRO Mode Instructions.
NOTE: You must make sure you have the correct RPM tach sticker for your machine. Use a 6-pulse (P/N 81510) tach sticker if your machine is a leadscrew machine or a 5-pulse tach sticker (P/N P/N 87860) if your machine is a ball screw machine.
Notes on ordering a metric mill
Most of our cutting tools, like center drills, are manufactured in a fractional size. If you have a metric machine with metric holders, like collets or end mill holders, you will need to order fractional holders to accommodate our cutting tools.
Standard equipment for the mill includes:
- A powerful 90V DC motor with electronic speed controller
- 18″ mill base with Y-axis leadscrew protection
- 2.75″ (70 mm) x 18.0″ (457 mm) extended mill table with two T-slots
- 7″ x 13″ tooling plate
- 15″ (63mm) extended column bed
- Extra-rigid column base
- Special handwheels are supplied with DRO machines. These handwheels can be reset to zero electronically with the push of a button on the DRO display box. Sherline DRO mills are outfitted with the special DRO 2″ (51mm) handwheels on the Y-axis leadscrew and X-axis table feed screw, and a 2.5″ handwheel on the Z-axis vertical feed screw. Each handwheel has laser engraved aluminum handwheel collars
- ¼” Drill Chuck w/ key, #1 Morse arbor with drawbolt
- Oil reservoirs on the X-, Y- and Z-axes
- Pulleys, drive belt, three hexagonal keys, spindle bars, gib removal tool, eight-foot three-wire power cord, and instruction manual
NOTE: The unit does not translate dimensions from inch to metric. It must be initialized to work with the pitch of the leadscrew to which the handwheel is attached.
