Advantages of vertical grinder
Release time: 2023-02-18
Less deformation, good roundness
On a vertical grinder, the workpiece is installed vertically in the chuck. On the horizontal grinder, the clamping force must ensure that the workpiece will not fall outside the chuck. For vertically clamped workpieces, only enough clamping force is required to resist grinding force. Gravity is beneficial to the grinding process rather than hindering it.
Since only small clamping force is required to fix on the vertical grinder, the workpiece deformation may be less. This reduces the probability of roundness error. According to the results obtained from the standard test workpiece, the vertical grinder can reach less than ± 1 µ; Roundness error of m (less than ± 0.000039 inch).
Complete processing by loading cards at one time
Vertical grinding machine can be used for outer diameter, inner diameter and surface grinding. According to the shape of the workpiece, all three tasks can be carried out in a single card loading. When this is possible, the error caused by multiple card loading is avoided. It can more accurately maintain the roundness between the inner diameter and the outer diameter, as well as the verticality between the inner diameter, the outer diameter and the surface. Because the workpiece and grinding spindle are vertical, there is actually no downward bending problem to be solved. The machine tool structure is inherently rigid.
Ergonomics
Vertical grinding machines are easier to load and unload. Manual loading and unloading do not need to support the workpiece while starting the chuck. The operator can simply install the workpiece down into the chuck. Make the workpiece alignment more natural, because there is no uneven gravity when the gripper is closed.
Loading and unloading with a crane or manipulator may also become easier, because the workpiece in the chuck has the same stable positioning on the rotary cart or transfer plate. For example, a dish-shaped part such as a gear can be transmitted horizontally downward for pickup and installation. Similarly, place it horizontally and downward in the chuck of the grinder.
The vertical grinder is usually smaller than its equivalent horizontal grinder. Vertical grinding machines occupy more height space and less floor space. This leaves room for automatic loader or manipulator beside the machine tool, making automation a more attractive option.
No dust
On a horizontal grinder, the sliding surface of the X and Z axes is lower than the point of grinding action. The vertical grinding machine places the guide rail of these shafts above the grinding action point. Grinding dust will not fall on these moving surfaces. This reduces wear, prolongs the service life of the machine tool, and maintains its accuracy.
