Load-tested spindles also help to produce accurate results. In addition, ouraccuracy and surface finish. Our precision surface grinding equipment also features an automatic lubrication system that minimizes wear to the equipment itself while ensuring the accuracy of the machines and the high-volume parts we produce.
Historically, grinding has generated the tightest tolerances and finest surface finishes compared to other metalworking processes. Advances in materials and components for part grinders and machine design are helping to preserve that advantage.
The specific tolerances represented by these tolerance codes must be determined based on the size of the basic dimensions. If 100h7,100 is the basic size (design theory size), 100h7 through the tolerance tolerance manual, its tolerance is (0,~0.035), unit mm. For 200h7, the tolerance is (0,~0.046) in mm.

The main reasons for the excessive radial runout of the surface grinder spindle are: (1) The spindle collides or deforms under force. (2) The roundness of the inner hole of the support bearing bush of the main shaft is out of tolerance. The grinding head part of the surface grinder adopts the support mode of the front and rear bearing shells.
