TOAUTO 3 Axis Customized DRO Kit
The TOAUTO 3 Axis Digital Readout Display and Glass Linear Scale kit is designed for customization. The X, Y, and Z travel lengths can be specified during order to match your lathe’s dimensions. The system uses precision linear glass scales for accurate position feedback across milling, turning, boring, and grinding applications. This kit supports movement monitoring and coordinate measurement, making it suitable for varied machine tool configurations. Custom sizing is supported after purchase by the TOAUTO service team, with a note that returns may incur partial costs if size changes are needed after customization.
TOAUTO 2 Axis DRO Display Kit for Lathe
This 2-axis DRO system combines glass scales with a high-contrast LCD display. It supports multiple languages, memory options, and a long-term power-off memory function. The kit includes a robust enclosure, shielded signal lines, and a durable keyboard. It is designed for Bridgeport-style knee mills, lathes, and EDM machines, offering streamlined drill and bore workflows with precise location indexing and repeatability in production runs.
ANBBIN 2 Axis DRO Set for Lathe
This 2-axis DRO set for table lathes uses magnetic scales with 5 μm resolution. The combination includes two axes, mounting brackets, a digital readout, and necessary hardware. Magnetic scales are favored for resistance to coolant, dust, and liquids, while enabling quicker, flexible mounting. The kit emphasizes durability and ease of adjustment, supporting efficient turning and facing operations with reliable position feedback.
TOAUTO 2 Axis DRO Kit (14″ + 28″)
This kit provides 2-axis DRO with a total measure length of 350 mm + 700 mm (14″ + 28″), expandable via customizable travel lengths. It uses a 5 μm resolution and supports a wide voltage range (AC 80–260V). The package includes the necessary brackets and mounting hardware for milling, grinding, or EDM applications. It is designed to improve machining accuracy and efficiency, particularly on multi-axis setups where precise tool offset tracking matters.
Baykunl 3 Axis DRO Magnetic Scale Kit
The Baykunl 3 Axis DRO Kit combines magnetic scales with a 5 μm resolution and a multi-axis digital readout. The kit emphasizes IP67 protection and durable construction, making it well-suited for environments with coolant spray, dust, or exposure to moisture. It supports flexible assembly to fit various lathe configurations and toolroom layouts, enabling precise control during turning, threading, and bore operations across three axes.
Buying Guide
- Travel length and axis count: Match the X, Y, and Z travel to your lathe dimensions. Consider modular or customizable kits if you foresee future upgrades or changes in your machine setup.
- Scale technology: Glass scales offer high accuracy and low drift but may be more fragile in rough environments. Magnetic scales provide ruggedness, IP-rated protection, and easier installation in challenging shop conditions.
- Resolution and repeatability: Look for a resolution that meets your precision needs (examples: 5 μm or better). Ensure repeatability aligns with your production tolerance goals.
- Durability and protection: Enclosures, shielding, and IP ratings influence long-term reliability in coolant-heavy or dusty workspaces.
- Power and connectivity: Check voltage compatibility (AC 80–260V is common) and whether the readout supports your preferred software or manual documentation formats.
- Installation ease: Kits that provide mounting brackets, sensors, and clear manuals save setup time. Consider brands offering support and detailed installation guidance.
- Warranty and support: Magnetic scale systems often include multi-year warranties. Confirm return policies for customized orders and the availability of technical support.
- Future compatibility: If you plan to upgrade to more axes or larger travel, choose a kit that scales with your needs, or that can be integrated with existing DRO components.
