Erith-based RK International Machine Tools, a leading supplier of high-quality machine tools in the UK and Ireland, has formed a partnership with DCM Tech, Inc, a renowned US-based machine tool manufacturer. This collaboration will bring DCM Tech's advanced surface grinding machines to the UK and Irish markets, enhancing RK International’s capabilities and offerings.

With over 40 years of experience supplying and supporting grinding applications, RK International has established itself as a trusted partner for industries requiring precision engineering solutions. The company’s extensive knowledge and expertise in grinding applications has served diverse sectors, including aerospace, automotive, power generation, and high-precision component manufacturing.

Simon Rood, RK International general manager, said: “Since its inception in 1951, RK International has been committed to procuring the finest machinery from world-class brands. With a 30-plus year relationship with Robbi and Jainnher and a nearly 15-year partnership with Delta, and Perfect, RK’s dedication to excellence is reflected in its comprehensive range of surface grinders, cylindrical grinders, internal grinders, and centreless grinders. RK International’s ability to offer CNC, PLC and manual models ensures we can meet the specific needs of our customers.”

Significant milestone
The partnership with DCM Tech marks a significant milestone for RK International. DCM Tech is renowned for its innovative IG Series surface grinders, which are designed to deliver superior performance, high material-removal rates, precision, and reliability. These machines are equipped with advanced features such as: user-friendly interface which simplifies operation and reduces the learning curve, making it easier for operators to achieve optimal results — many operators are efficiently running parts on day one; variable speed spindle and table control which allows for precise adjustments to match the specific requirements of different materials and applications; automatic down feed which ensures consistent and accurate material removal, enhancing the quality of the finished product — programmable maximum spindle load to prevent part damage; automatic part detection which reduces process time by avoiding “grinding air”; wide-ranging work holding solutions — these provide secure and stable work holding, which is essential for achieving high-precision grinding — they include electromagnetic chucks, vacuums, and nesting-style fixtures; and closed loop coolant filtration system — integrated coolant and air mist systems to help manage heat and maintain the integrity of both the machine and the workpiece.

DCM Tech’s surface grinders offer numerous benefits that make them an excellent choice for various grinding applications, including: enhanced precision — the advanced control systems and robust construction ensure high-precision grinding, resulting in superior surface finishes and tight tolerances; increased productivity — features like automatic down feed and variable speed control streamline the grinding process, reducing setup times and increasing overall productivity; versatility — these machines can handle various materials and applications, making them suitable for diverse industries, including non-ferrous applications; ease of use — the user-friendly interface and intuitive controls make it easy for operators to achieve optimal results, even with minimal training; and durability and reliability — built with high-quality components and designed for long-term use, DCM Tech’s grinders offer reliable performance and low maintenance requirements.

Mr Rood continued: “UK manufacturing has a legacy of large, heavy surface grinding machines with vertical grinding spindles and segmented wheels. As with other grinding equipment we supply today, we often find ourselves replacing grinding machines dating back to the 1970s or earlier.”

Additional grinding options
The DCM IG range provides capacities to 1,220mm diameter rotary tables with a maximum swing of 1,320mm diameter. Built across two control platforms, the IG 80 Series provides the basics for rotary table surface grinding. The enhancements on the IG 82 Series include additional grinding options such as regrind and continuous grind, along with servo precision-controlled X and Z axis with home positioning.

The IG 82 Series is equipped with additional features, including automatic part detection and available auto-dressing with selectable dress frequency. The 82-Series grinders are also supplied ‘robot ready’ and can be integrated with third-party robotic arms for a fully automated loading and unloading grinding process.

Jennifer Rutz, president of DCM Tech, added: “We are excited to collaborate with RK International to expand our advanced surface grinding technology presence in the UK and Ireland. RK International's extensive experience and commitment to customer satisfaction align perfectly with our values. We believe this alliance will benefit UK customers significantly, offering cutting-edge solutions for their grinding needs.”

Through this partnership, RK International will expand its product portfolio and enhance its ability to support customers with innovative grinding solutions. The company’s team of factory-trained technical specialists will provide comprehensive support services, including installation, maintenance, and training, ensuring that customers can maximise the performance and longevity of their new DCM Tech machines.

RK International has always prioritised customer satisfaction by understanding each application and installation’s unique challenges and requirements. The company’s approach to delivering customised solutions has earned it a reputation for reliability and excellence in the industry.

By adding DCM Tech’s surface grinders to its product line-up, the company further reinforces its commitment to providing the best possible solutions to its customers. A DCM Tech IG280SD rotary surface grinder will be on show at the forthcoming IMTS exhibition in Chicago, taking place 9-14 September (North Building level 3, Booth #237070).
