Heavy Duty Studer

The capabilities of the well proven Studer S36 have been expanded for production applications with a wheel head version for grinding wheels 24" x 6.3". Designated the S36 HD, or Heavy Duty, the grinding wheel is driven by a powerful 20 HP spindle. These enhancements, along with a center height of 8.9", allow for efficient grinding of high precision automotive and hydraulic components. The S36, with the cross-slide concept, is extremely compact and economical in terms of space requirements. It can be automated with the new Studer Easyload, which fully integrates within the machines Fanuc control for increased productivity in high production environments. 

S36 HD overview

Heavy-duty linear guideways support the X-axis, while V and flat guideways, coated with abrasion-proof Granitan S200, support the Z-axis. The machine base of Studer-developed Granitan S103 delivers outstanding vibration dampening, rigidity and strength, as well as excellent chemical stability and thermal compensation.  Digital direct-drive, three-phase servo motors with 40-mm diameter prestressed, precision ballscrews power the X- and Z-axes.   Cross slide X-axis travel is 10.5" at speeds ranging to 195 IPM.   

Dressing

Wheel dressing intervals may be made by the operator following these simple methods: by pressing a pushbutton at any time during any grinding cycle; after a programmed number of specific machined parts or grinding operations; at programmed switchover points; at the programmed nominal size; after a specific number of strokes - or a combination of these, permitting the optimum solution for the specific grinding application. Grinding wheel reference points are referred to as "T" numbers, and together with Studer grinding cycles, "T" numbers permit programming with nominal sizes.  The actual value indication on the control LCD refers in each case to the programmed wheel reference point.  Values of the grinding wheel shape are entered in a dressing dialog display at the control. 

Control & Programming

The S36 HD features state-of-the-art Fanuc 16i digital control and axis drive components.  Machine operation, setup, changeover, dressing and programming of even complex parts are easily accomplished through the innovative, step-by-step Studer Pictogramming which allows operators simply to connect grinding cycles to one another and add necessary numerical values.  The control then generates the machine program automatically.  Advanced manual programming in G code is of course also possible.  Programming is done directly at the machine or off-line and then downloaded to the machine control.  Process parameters can be changed on the fly, while the machine runs, without affecting the workpiece program.
