Characteristics of a Horizontal Spindle Reciprocating Table Surface Grinding Machine
Within the grinding machine, the vibrations are implied from the drives of spindle rotation and linear motions of the axes slides. The factors which govern the amplitude and frequency of vibration in the machine tool structure are the excitation applied and the response of the structure to that particular excitation.
Reducing the excitation or improving the structural response or both can attenuate the level of vibration in the grinding machine tool structure. The source of excitation can either be relocated or isolated from the structure so that the generated vibration is not transmitted to the spindle and slide support system. Structural response can be altered by changing the stiffness of the structure or increasing the damping.
Leading factors for grinding chatter within the grinding process are grinding wheel imbalance, improper dressing, and excessive depth of grinding. Poor dressing by single point dressers results in waviness along the grinding wheel periphery, which leads to chatter along the workpiece surface.
Horizontal Spindle Reciprocating Table Surface Grinding Machine makes provision for the cross and vertical motion of the rotating grinding wheel, whereas the table carrying the workpiece reciprocates in order to affect material removal to generate flat surfaces.
Though grinding performance can be significantly improved by optimization of process parameters, true progress in process performance may not be achieved without a consistent improvement on the machine tool itself. For a step change in quality and productivity in horizontal spindle reciprocating table surface grinding, it is essential to drastically improve the machine motion accuracy as well as the static / dynamic stiffness.
Guaranteed performance for a Horizontal spindle reciprocating table surface grinding machine can be claimed based on a grinding spindle with high precision and high stiffness, a slide ways system with high damping, high stiffness, and high positioning accuracy.
