Delta Srl, a specialist in surface grinding machines, has introduced its new Mini 20, extending the capacity of its Mini travelling-column range. Available in the UK through agent RK International Machine Tools, the fully automatic Mini 20 is designed for high-precision applications, offering a maximum grinding length of 2100 mm and width of 600 mm, or 650 mm with the 100 mm wheel option.

Established in 1955, Delta has specialised in surface grinding for more than 70 years. The company pioneered the travelling-column design for large surface grinders in the early 1980s before adapting the technology for smaller machines with the Mini family in 2005. Today, DELTA manufactures its machines at its modern headquarters near Pavia, Italy.

The Mini 20 combines a rigid Meehanite cast-iron structure with hydrostatic ways on all three axes. The closed-loop pressurised oil system eliminates sliding friction and stick-slip, delivering smooth, accurate movement while maintaining geometric accuracy throughout the machine’s service life. Its 2000 x 500 mm table remains fully supported during longitudinal travel.

A Mackensen hydrodynamic spindle bearing provides zero metal-to-metal contact, contributing to long service life, quiet operation and high-quality surface finishes. The Mini 20 is available with three levels of automation, including Delta’s proprietary Diastep control, which enables operators to manage grinding cycles, rough and finish passes and automatic wheel dressing.

The machine supports workpieces weighing up to 1500 kg and has an approximate net weight of 7000 kg.

“After 15 years of working with DELTA, we’re seeing growing awareness of its build quality and attention to detail,” says Simon Rood, director at RK International Machine Tools. “As customers demand ever greater accuracy, the DELTA range continues to perform at the highest levels.”
