JB/T 8333 的本部分规定了一般用途的轻便悬臂刨床、龙门刨床的预调检验、几何精度和工作精度的检验及相应公差。
本部分适用于最大刨削宽度800 mm～1 250 mm 轻便悬臂刨床、龙门刨床。
本部分中所有线性尺寸及相应公差，均用毫米为单位表示；角度公差主要用比值表示。
当实测长度与本部分规定的长度不同时，公差应按GB/T 17421.1—1998 中2.3.1.1 的规定，公差最小折算值为0.005 mm。
工作精度检验应在精加工后进行，而不在粗加工时进行，因为粗加工易产生较大的切削力。
This part of JB/T 8333 specifies the preliminary adjustment inspection, geometric accuracy and working accuracy inspection and corresponding tolerances for general-purpose portable cantilever planers and portal-type planers.
This part applies to portable cantilever planers and portal-type planers with a maximum planing width of 800 mm to 1 250 mm.
All linear dimensions and corresponding tolerances in this part are expressed in millimeters; angular tolerances are mainly expressed as ratios.
When the actual measured length differs from the length specified in this part, the tolerance shall be in accordance with the provisions of GB/T 17421.1—1998, clause 2.3.1.1, with a minimum converted tolerance value of 0.005 mm.
Working accuracy inspection shall be carried out after finishing, not during roughing, because roughing tends to produce larger cutting forces.
