The new MF1000-3T deep-hole drilling machine from IMSA takes advantage of the benefits provided by NSK’s DIN-standard ball screws for the European machine tool market. The long-standing partnership between IMSA and NSK dates back many years and involves the development of numerous machine models. IMSA intends to show the new MF100-3T at the EMO Milano machine tool exhibition in October 2021.
Established in 1988, IMSA is located in Barzago, northern Italy, from where core business centres on the design and manufacture of deep-hole drilling and gun-drilling machines. As a leading company in its field, there are now more than 500 such IMSA machines operational worldwide. Applications are wide and varied, but many focus on the gun drilling of mould tools for the automotive industry. Seven IMSA models for this purpose came to market between 2014 and 2019 alone. Thanks to a series of options, each standard base model is custom-built according to the specific requirements of customers, although the company can also design and manufacture completely bespoke solutions.
NSK’s ball screw, which conforms to DIN 69051 (ISO 3408) with regard to both dimensional and tolerance classes, meets IMSA’s performance demands in term of speed, accuracy, load capacity and rigidity. The first NSK DIN-standard ball screw order is due for delivery in May 2021 to meet the requirements of a prototype MF1000-3T. NSK RA65 roller guides will also form part of the order.
Manufactured in shaft diameters from 32 to 63 mm, and with leads from 10 to 40 mm, NSK DIN-standard ball screws offer a speed factor of 160,000 dn. This performance level makes them ideal for use without restriction in high-speed machining applications where very accurate positioning is also required. In addition, the smooth running properties of the ball screws ensure the least possible vibration in the linear system, while simultaneously reducing noise levels.
