DOUBLE-DISC SURFACE GRINDING

TWO GRIND QUICKER THAN ONE With SATURN double-disc surface grinding, two vertical grinding wheels simultaneously grind the workpiece on its parallel outer surfaces. The grinding wheels are set against each other at a slightly conical angle, so that as it passes from top to bottom, the workpiece retains its final dimension only in the bottom section of the grinding path. Because the workpieces are fed vertically between the grinding wheels, the bearing weight of the workpiece does not affect the grinding result. What’s more, the coolant can simply drain downwards together with the removed material....

ROTATION PROCESS PENDULUM GRINDING With SATURN double-disc surface grinding using the rotation process, a closed or an open breaker plate (star plate) feeds the workpieces between the grinding wheels and the guide plates, which are automatically adjusted by the control. This through-feed grinding process, which employs a rotating workpiece carrier, is suitable for a number of workpiece shapes, as well as for cylindrical or square elements. In the case of small parts such as piston components, needles, bushings etc. with diameters of approx. 8 mm, cycle times of as high as 450 parts per minute...

SATURN IMPROVES COSTEFFICIENCY EXPERTISE FOR GRINDING LARGE-SCALE SAFETY THROUGH EXPERIENCE The SATURN double-disc surface grinding machine is suitable for workpiece diameters from 5 to 200 mm. Its design combines the latest technical insights into grinding and JUNKER’s long-standing experience, offering ideal solutions for meeting all requirements relating to output and ease of operation. Swift process flows achieve high efficiency for large-scale standard production. The ease of retooling enabled by the simple procedure to change the transport wheel is valued especially for small batch sizes....

TECHNOLOGY FOR DAILY PRODUCTIVITY DESIGNED FOR PRECISION GRINDING SPINDLE HEAD A compact grey cast iron bed with stabilising ribbing carries the two spindle headstocks and rotation tool carriage. To change the workpiece guide tool or any other component, this is simply moved outwards. Both its front section and the transition of the spindle headstocks to the grinding spindle sleeves are protected by belows cover and telescopic metal covers. The grinding wheel is changed from the top through a manually opening door. The two SATURN spindle headstocks of the grinding wheels are mounted on three...

EQUIPMENT AND OPTIONS CONTROL SYSTEM The Erwin Junker Operator Panel was specifically developed to control grinding machines. All machine components are controlled using the operator panel – irrespective of the series and the used control system. The identical structure, intuitive menu guidance and visualization of the workpiece geometry make for extreme user convenience and flexibility in operation. Programming takes place directly using the operator panel or an external programming tool. FIRE PROTECTION AND LTA AIR FILTER In case of an explosion, the machine interior is automatically hermetically...
