  • Determined to transform the concrete grinding industry, WORX+ set out to develop a ground-breaking new machine to address key design challenges head-on: •Balancing power with accessibility - Achieving the productivity of large ride-on machines without sacrificing maneuverability. •Enhancing precision and automation – Optimising controls to increase operator output, quality and consistency. •Improving control and transportability - Reimagining how a 500kg+ machine can be handled, moved, and deployed. •Reducing operator strain - Addressing the physical demands that lead to long-term wear-and-tear injuries. •Streamlining disc changes - Eliminating inefficiencies caused by limited access. •Prioritising user-centred design - For both functionality and next-level aesthetic appeal.

  • The Grindworx King Series revolutionises grinding with its innovative split-chassis design. This compact machine enhances maneuverability and automatically splits to shift weight rearward, easing tilt for quick disc changes and reducing user strain. The dynamic chassis allows real-time weight adjustments at the grinder head, improving grind quality far beyond manual systems. With real-time data, remote-controlled wheel drives and autopilot intelligence at your fingertips; more efficient, precise polishing and easy transport with minimal manual effort becomes possible. Engineered for superior performance, control, adaptability whilst prioritizing safety & comfort on every job site, this cutting-edge design sets a new standard in the industry.

  • The Grindworx King Series boosts productivity with superior power, pressure control and autopilot technology. Now users can focus on the quality of the grind while maximising output by reacting to real-time data. There is a profound impact on the operator’s health and longevity in the industry via reduced manual effort and exposure to vibrations throughout the entire use cycle. WORX+’s growing market share reflects its commitment to smart design, premium materials, and visually striking industrial products. By advancing grinder capabilities, the Grindworx King Series supports a shift from environmentally harmful floor coverings and sealants, promoting sustainable concrete finishing practices.
