Junker offers its Jucrank platform for cylindrical and non-cylindrical grinding with a swing diameter of 470 mm and a part length capacity ranging to 4,800 mm. Initially designed for grinding and re-grinding of large crankshafts, the machine can also be used for grinding printing rollers, electric motor shafts and other heavy workpieces.

To ease part setup, the Jucrank has a slide with an integrated length measuring system that enables the technician to first bring the work heads into position, and then the steady rests. This machine’s CNC steady rests have only one axis each, increasing their stability and stiffness. Each of as many as 11 steady rests can be controlled individually and applied to a section at any time, even during the grinding process, for greater flexibility. This capability is supported by a high-performance control system supporting at least 24 CNC axes.

An integrated measuring system helps prevent scrapping of forged and hardened workpieces such as crankshafts and enables completing grinding in one setup. The system measures main and pin bearing diameters during the grinding process, and measures the entire workpiece afterward including the taper of each element, bearing widths and lift heights. Based on the measuring data, the machine finishes the grinding process while using the WK axis, which swivels the grinding spindle, compensating for tapers in the process. The grinding machine can therefore provide each main and pin bearing with its own profile shape, and then grind the two shaft ends, if required.

  • Between Centers And Centerless Grinding In One Setup

    It sounds like a contradiction in terms-between centers and centerless grinding on one machine. But for some categories of workpieces, it's a viable production process that can yield machining time reductions of 45 percent over separate grinding operations.

  • Getting The Most From Creep-Feed Grinding

    No other process can do what creep-feed grinding can do. Recent tests show even more can be gained by optimizing every element of a creep-feed system.

  • What Is Single Point OD Grinding?

    Two enabling technologies -- superabrasive wheels and high precision servo control -- come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.
