If your roll requires precision grinding, Western Machine Works has skilled technicians and state-of-the-art grinding equipment to meet your needs and specifications. We have been providing precision grinding services for a variety of rolls and cover types since 1985. Pre-grind and post-grind profiles are taken using our customized Pro-Mic Roll ...
Vibration produced by rolling bearings can be complex and can result from geometrical imperfections during the manufacturing process, defects on the rolling surfaces or geometrical errors in associated components. Noise and vibration is becoming more critical in all types of equipment since it is often
Although this grinding mark is indistinguishable from the surface roughness measurement value, it is transferred to the surface of the rolled sheet material to reduce the product yield, or causes...
Based on a doubly regenerative time delay grinding model, a 2-degree-of-freedom lumped parameter model of a roll grinder with the roll misalignment fault is presented to investigate the effect of a roll misalignment on its vibration responses.
Our roll grinding experts will help return your rolls to the proper roundness, concentricity, shape, profile match tolerance and surface finish — ensuring they exceed OEM specification. We're capable of holding tolerances down to +/- 20 millionths of an inch with our equipment, allowing us to meet your mill's needs, not only for tight ...
GROUND LEVEL ACCESS: Wear parts at ground level allow for easier and safer maintenance of the roll assemblies and grinding ring. FOUNDATION: Because the gearbox is above this mill, a simple, solid flat foundation block is used, which minimizes vibration and noise and reduces installation costs.
If a roll is not round, it will vary nip pressure in every rotation and cause vibration. This can cause roll cover barring or vibration further down the machine. In some cases it can cause MD caliper variation in the sheet.
Vibration monitoring On request, the motors can be equipped with vibration sensors. The drive system can be set to raise alarms upon recording abnormal vibration levels in the motor, which may be caused by excessive forces being transferred from the HPGR due to process abnormalities (e.g. irregular or oversized feed). Surge protection feature

The vibration generated by the processing system during the grinding process directly affects the quality and productivity of the roll surface. If the vibration is not eliminated and suppressed in time during the semi-finishing and fine grinding …
The vibration source of roll grinder mainly comes from the following aspects: (1) The main reason is that the grinding wheel drive motor is unbalanced and produces vibration. (2) The grinding wheel does not balance dynamically and statically and vibrates when it rotates.
Thus, in the present work, a Molecular Dynamics model of vibration-assisted nano-grinding is introduced, with a view to determine the efficiency of this process under various conditions, by comparing its outcome to that of a conventional nano-grinding process via analyzing grinding forces, temperatures and subsurface damage of the workpiece.
The vibration amplitude, which is the characteristic that describes the severity of the vibration, can be quantified in several ways. On the diagram, the relationship between the peak-to-peak level, the peak level, the average level, and the RMS level of a sinewave is shown.
Product description. Roll grinders ideally complement the product range of ANDRITZ METALS. With its high-precision, CNC-controlled V series, ANDRITZ METALS is setting the standards for the next generation of roll grinders.

Unlike many in-house grinding operations, PRG has the technology to grind the entire journal areas of each roll, as well as the barrel surface. Our craftsmen and specialized grinders can achieve less than 0.0001 TIR on roll-bearing seats and setup spots, resulting in: More finished stock from less raw metal. Longer life and productivity between ...
Alarm limits can be set to control the acceptable vibration values during the different parts of the grinding cycles. The system interfaces with the grinding controls to obtain roll parameters (diameters, depth of cut) and operating parameters (wheel load, traverse, normal force, overlap ratio, and aggressiveness).

The vibration amplitude at the second set of conditions was measured at 8 microinches versus 79 microinches when grinding at first set of conditions. Again, the imbalance remained the same. But grinding at conditions consistent with contact-length filtering produced a smooth surface despite the imbalance, without any reduction in productivity.
