3-Axis Lathe DRO
Select the inch/metric option to match the DRO handhweels to your machine’s leadscrew pitch. All ball screw machines use a metric pitch.
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 68060) if your machine is a ball screw machine.
This kit is installed on a lathe with a vertical milling column to give a full 3-axis digital readout, the same as on a mill. For more details on the mill digital readout, see P/N 8100.
As a cost-saving measure, an accommodation has also been made for owners of both a lathe and mill to use a single electronic display box for both machines. The input cables from the lathe can be unplugged and the readout box transferred from the lathe to the mill and vice versa. Depending on which machine you already have fitted with a DRO, ask for the upgrade for the other machine that allows you to use your existing box. See P/N 8210 if you already have a lathe with a DRO. See P/N 8220 if you already have a mill with a DRO.
220-240 Volt Electrical Current
The DRO power supply automatically switches from 120V to 240V for countries with 220-240 volt electrical current.
NOTE: The DRO can be ordered on any new machine as a factory-installed option. The digital readout handwheels replace the standard handwheels that would normally come with the machine. If you purchase a machine with factory-installed DRO, the regular handwheels are not included. If you purchase the DRO as a separate option and install it yourself, you will have the stock handwheels left over.
Always wear safety glasses when operating machine tools.
