4-Axis DRO Kit (LCD) with Linear Scales for 2A622 Horizontal Boring Machine
A complete professional solution for upgrading the 2A622 horizontal boring machine. This 4-axis Digital Readout (DRO) kit features a modern LCD display and a combined measurement system to ensure high positioning accuracy, reduce scrap rates, and significantly increase operator productivity.
A key feature of this kit is the use of a magnetic linear scale for measuring the horizontal movement of the spindle. This engineering solution guarantees trouble-free operation even in environments with heavy chip accumulation and coolant usage, where traditional optical systems can be vulnerable.

💡 Key Features & Advantages for the 2A622 Machine
- Spindle Node Reliability: The magnetic scale (1000 mm) is completely immune to oil, coolant, metal dust, and vibrations. This makes it the ideal choice for monitoring the spindle extension on a horizontal boring machine, where operating conditions are most aggressive.
- Informative LCD Display: Unlike traditional LED displays, the LCD screen offers superior readability, displays graphical help prompts, and features an intuitive user interface for fast machine setup.
- Combined System (Optics + Magnetics): Combining optical scales and a magnetic system delivers the perfect balance of cost-efficiency and industrial reliability.
- Durable Housing: Both the DRO unit and the reader heads feature dust- and moisture-resistant enclosures specifically engineered for harsh workshop environments.
🛠 Main DRO Functions
- Axis zeroing and coordinate presetting.
- Absolute (ABS) and Incremental (INC) coordinate modes.
- Millimeter / inch conversion.
- Radius / Diameter readout mode.
- Center-finding function (divide-by-two).
- 200-tool memory library.
- Built-in calculator for complex on-the-spot mathematical operations.
- Bolt-hole circle (PCD) and linear hole pattern drilling.
- Linear error compensation (accounting for machine guide wear).
- Power-off memory.
