The Sherline 3-Axis Lathe DRO w/ CNC Thrust Collars (Metric) is an advanced digital readout system designed to enhance the functionality of a lathe equipped with a vertical milling column, effectively transforming it into a 3-axis machine similar to a mill. This system includes CNC thrust collars, which facilitate the integration of stepper motors, thereby enabling precise control over the lathe's movements. The digital readout system operates by electronically translating handwheel rotations into table movements, rather than measuring the table movement directly. This feature is particularly beneficial for CNC users who wish to verify the accuracy of the leadscrew movement against the CNC input, ensuring that the axis has moved the intended distance as dictated by the stepper motor input.
An innovative aspect of this system is its cost-effective design, which allows owners of both a lathe and a mill to utilize a single electronic display box for both machines. This is achieved by simply unplugging the input cables from one machine and transferring the readout box to the other, thus eliminating the need for multiple display units. The system is compatible with both inch and metric machines and offers six different operational modes to accommodate various machine types, including mills, lathes, leadscrews, and ball screws.
The power supply of the digital readout system is versatile, automatically switching between 120V and 240V, making it adaptable to different power sources. However, it is important to note that the system is designed for manual use and is not suitable for CNC machines operating at speeds exceeding 15 inches per minute (381 millimeters per minute). The installation process requires the removal of handwheels to accommodate the CNC stepper motor mounts, which is a necessary step to fully integrate the system with the lathe.
Note: Exercise caution when removing handwheels to avoid damage to the machine or injury.
