Transforming manual machining for 60+ years
Customers have trusted Acu-Rite Solutions to enhance their machining capabilities for decades. Designed and built in America, our intuitive and durable CNC controls, digital readouts, and encoders boost accuracy and productivity. Browse highlights of our history of product development.
First CRT-based Readout
Acu-Rite Solutions unveiled the market’s first readout system with cathode ray tube (CRT) technology in 1986, a year after acquisition by HEIDENHAIN. The CRT-based readout, later known as a vision readout (VRO), would drive the development of early DROs.
Between 1986 and 1992, Acu-Rite Solutions introduced VROs for milling, turning, and EDM applications—the MiLLVISION, TURNVISION, and EDMVISION.
Application-specific DROs
Acu-Rite Solutions launched application-specific DROs in the 1990s, designed to be both precise and cost-effective. The MillMate and TurnMate were for milling and turning, the Qwikcount was for grinding, and the Master series of programmable DROs was for milling, turning, grinding, and general-purpose applications.
Precision Glass Scales
Acu-Rite Solutions continually builds on its tradition of durable precision glass scales. Between 1980 and 2020, it introduced 11 linear encoders and numerous product updates. The most recent additions are the ultra-compact SENC 50, the robust SENC 150, and the LMF 9310 for large machine tool applications.
Acu-Rite Solutions linear encoders provide precise, repeatable feedback at an affordable price. Over one million of our glass scales are currently in use.
First CNC Control
Acu-Rite Solutions entered the CNC control market with the MILLPWR in 1994, a 2-axis CNC control and a 3-axis DRO. The MILLPWR is a flexible and cost-effective solution for increasing the accuracy and efficiency of manual milling machines.
Acu-Rite Solutions enhanced the MILLPWR in the early 2000s, making it one of the most accurate CNC milling controls in its class. Many MILLPWRs are still in use today.
Expanded DRO Capabilities
In the 2000s, multiple new Acu-Rite Solutions DROs hit the market with expanded capabilities. Acu-Rite Solutions DROs became available for mills, lathes, grinders, EDMs, optical comparators, and almost any manual machine tool use known to the industry.
Next-Generation CNC Controls
The next-generation Acu-Rite Solutions MILLPWRG2 milling CNC control became available for vertical knee mills in 2013 and bed mills in 2019. It boasts a high-resolution and intuitive display, conversational programming, and 3D graphic prompts, further improving user efficiency and productivity.
The TURNPWR CNC control was unveiled in 2020, providing the market with an easy-to-use, workshop-oriented turning control with state-of-the-art features.
Control Bridge Adapter
In 2022, Acu-Rite Solutions launched the PCBA Bridge Adapter to bridge an Acu-Rite Solutions CNC control to the HEIDENHAIN TNC 320 CNC control on the same machine. It allows for easy upgrading from the Acu-Rite Solutions MILLPWR to the next-step HEIDENHAIN TNC 320 or switching between both controls, such as in teaching environments and machine shops.
Most Complete DRO Line
The Acu-Rite Solutions DRO100, DRO203, and DRO300 launched in 2018 for milling, turning, grinding, and boring applications. The DRO203Q joined the line-up a few years later for metrology applications.
They have numerous innovative features, including a 7-inch color display, a built-in installation guide, dynamic zoom, and day/night switching. With enhanced functionality and robust hardware, these models make up the most complete DRO line in the industry.
Technology Education Center
In 2021, HEIDENHAIN CORPORATION opened the Acu-Rite Solutions Technology Education Center at its headquarters in the Chicago suburbs. The center builds on the Acu-Rite Solutions legacy of dedicated local support, providing North American customers hands-on access to Acu-Rite Solutions machine tool components, expert training, and personalized assistance.
droPWR iOS App
The first-of-its-kind Acu-Rite Solutions droPWR iOS App joined the App Store in 2022. The droPWR transforms an iPad® into a cable-free, Bluetooth-enabled DRO for milling, turning, and grinding machines. It combines traditional Acu-Rite Solutions DRO features with modern touchscreen capabilities, enhancing usability and flexibility in diverse production environments.
