A Legacy of Precision
For over 50 years, Acu-Rite Solutions has been a trusted name in digital readouts (DROs), linear encoders, and CNC controls. Our products have shaped how machinists, educators, and manufacturers approach precision, making workflows simpler, faster, and more reliable. From small shops to technical schools to large production facilities, Acu-Rite Solutions has always stood for accuracy and usability.
Backed by HEIDENHAIN
Acu-Rite Solutions is part of the HEIDENHAIN family of brands, a global leader in motion control and precision measurement technology. This partnership combines the reliability of U.S.-based service and support with the engineering excellence and global innovation of a worldwide technology powerhouse.
From Acu-Rite to Acu-Rite Solutions
In 2024, we rebranded as Acu-Rite Solutions, marking our evolution from a product provider to a solutions partner. Today, we deliver more than DROs and controls—we provide integrated packages that include encoders, accessories, training, and responsive support. This shift reflects our commitment to helping machinists and educators meet the challenges of modern manufacturing and workforce development.
Supporting Machinists and Educators
Our solutions play an important role on both the shop floor and in the classroom. In education, Acu-Rite Solutions helps students gain confidence with industry-standard equipment. In professional shops, our products reduce costly errors, improve productivity, and withstand the daily demands of machining. Whether it’s a retrofit project or an advanced training program, we deliver the tools and support needed to succeed.
Our Commitment
At Acu-Rite Solutions, we believe that every measurement matters. That philosophy drives our focus on durability, accuracy, and ease of use—backed by responsive technical support and a dedication to continuous improvement. We’re here to provide solutions that not only meet today’s needs but also prepare machinists and educators for tomorrow.
Our Journey
The story of Acu-Rite Solutions is one of steady innovation and growth. In the 1960s and 1970s, we pioneered DROs that revolutionized precision measurement. The 1980s and 1990s brought the introduction of linear encoders and CNC controls, further expanding our reach. By the 2000s, Acu-Rite Solutions had joined the HEIDENHAIN family of brands, gaining access to global research and development resources. In the 2010s, our products became a mainstay in machinist training and technical education.
In 2024, we reintroduced ourselves as Acu-Rite Solutions, reflecting a broader mission: to deliver complete, integrated solutions for modern manufacturing. Today, we continue to combine our proud heritage with new technology, serving machinists, educators, and manufacturers across North America with precision, reliability, and innovation.
Acu-Rite Solutions creates infinite machining possibilities, from re-creating classic aircraft parts to prototyping a line of popular tattoo machines.
Our easy-to-use precision technologies help machinists, educators, and hobbyists achieve better positioning accuracy while saving time and cost. Transform your machining capabilities and grow machine tool profitability.

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.
