NSK’s ground ball screws, linear roller guides and super-precision ball bearings are helping IMSA to consolidate its market position in the field of specialised deep-hole drilling machines, which are particularly popular for mould-making applications in the automotive sector.

“Our partners have always played a fundamental role in all of the technological innovations that distinguish our company,” says Marco Colombo, head of the technical department at IMSA. “In order to put our design ideas into practice, we use top-quality components that can guarantee the best performance and reliability over time. For example, NSK has always been our point of reference in motion control throughout the evolution of our machines. The availability of optimal-quality NSK bearings, ball screws and linear guides has allowed us to build the highest performance machines in our sector.”

One of IMSA’s most recent innovations has been the development of a rotary-tilting table, which allows the machining of moulds in five axes using just one clamping position, further reducing manufacturing time. MF1000-3T EVO, a deep-hole drilling machine for small to medium automotive moulds up to 2.5 tonnes in weight, is the first model to be equipped with this solution. Here too, IMSA is using NSK’s latest-generation solutions to achieve the very high performance required.

“To transform axial movement into rotary movement, we use two 63 mm diameter NSK ZSS series ground ball screws,” says Colombo. “Compared with the ball screws of previous generations, they guarantee greater rigidity and perform better in terms of speed and load capacity. As a result, the machine’s working axes can move at feed rates of up to 30 m/min.”
