Why Prostar ? (Characteristic)

When our customers requested a massive machining centre that would accommodate the big parts and heavy cuts their aerospace and energy customers were ordering, we knew the design and mechanical engineering was critical. After reviewing various configurations, the PROSTAR engineering team opted for a double column design because they determined it would provide superior dynamic behavior and promote thermal stability compared to other options. The large table capacity allows nearly any part you have to be machined.


For over two decades Shubhline has continually focused on the development of technology that yields measurable productivity improvements for our customers. Our years of experience provide us the knowledge to build rigid and reliable machining centers with the most powerfully simplistic, user-friendly control technology in the industry. Our experience has also allowed us to implement a unique business model within the machine tool industry that expands our global supply chain, manufacturing, and distribution capabilities. This proven system benefits our customers because we are able to ship our machine tools with shorter lead times than most competitors. Additionally, we are able to continue product development schedules and targeted technology growth even during difficult economic cycles because our efficiency promotes financial stability.

Premium Components Increase Performance

We focus our efforts on reducing your overall cycle time while minimizing time wasted on non-cutting operations, by incorporating time-saving features in our SHF double column machining centre design and using premium components. 


• The Heart of the Machining Center.  The SHF CNC double column machining centres feature a powerful TRIQUENCH spindle. The low base-speed of the spindle provides more torque for the machine without needing a gearbox, which eliminates additional assembly and maintenance.

• Prolonging Spindle Life + Preserving Accuracy. Prolonging Spindle Life + Preserving Accuracy. We have systems in place to prolong spindle life and combat spindle growth caused by heat dissipation. We use (4) ABEC Class 7, 25-degree angular contact bearings in the SHF spindles. These bearings run at much lower temperatures, so they have a significantly longer lifespan and a much lower probability of failure. Because keeping the spindle and work area clean is vital to machine performance, we incorporate an upper and lower air-purge system to keep contaminants outside of the spindle.

• Best-In-Class Chip Management. High pressure, high-volume, stainless-steel coolant ring with adjustable nozzles delivers coolant right to the tool. Dedicated large capacity pump system and the dual auger that lifts up to a chip conveyor eliminate costly cleanup and save valuable time. Sloped telescopic way covers protect the internal components of the machining center.
