Vibration Control, Mounting and Levelling of: ROLL GRINDERS
Roll Grinding Machines or Roll Grinders are high precision machines typically installed in steel, aluminium and paper mills and precision machine shops to grind smooth and textured rolls to very tight tolerances. On first appearance they look rather like a lathe but in reality they are required to achieve much tighter tolerances as
CHAPTER 1- INTRODUCTION TO GRINDING
Advent of advanced grinding machines and grinding wheels has elevated the status of grinding to abrasive machining where high accuracy and surface finish as well as high material removal rate can be achieved even on an unhardened material. The bulk grinding wheel – workpiece interaction as given in Figure 2 can be divided into the following
Good Practice guide to measure roundness on roller
One of the multi-point methods commonly used in the roll geometry measurement devices of the roll grinding machines is the so called Hybrid four-point method. The method behind the Hybrid four-point measurement device is based on the three-point Ozono method, but in a combination with the two-point (diameter) measurement method. The two-point
Practical Roll Techniques
Sep 13, 2013· The correct way to measure concentricity on a grinding machine is 180º from wheel (back side), if the roll is supported on grinding seats. For example, if the grinding seat is out of round this form will be transferred to the roll shell by the grinding wheel. Run-out .
ProfiGrind Roll Grinders
To date, more than 1,600 roll grinding and texturing machines from WaldrichSiegen are being operated in roll shops worldwide. Consistent focus on precision and reliability The roll grinders of the WaldrichSiegen ProfiGrind series are renowned for their very rigid design.
The characteristics and shape of the material dictate the choice of grinding wheel specification. MACHINE CHARACTERISTICS Foundries (roll manufacturers): • Roughing rolls - work and back up • Spin cast high chrome, high speed steel Typical metal removal: • 3 to 15 kg/s/mm • 2 to 7 kg/kWh (on stainless steel) Application •Cold grinding
Numerical and Experimental Approach for Roll Grinding Process
1 Introduction In paper machine industry, a roll grinding machine is used to finish or maintain roll surface. Excellent surface finish should be homogenous one with silky sheen, free of scratches and any other blemishes. Precision roll provides more efficient roll operation and better paper quality. To understand the dynamic
