AI Summary AI generated
This standard specifies the types and parameters of heavy duty deephole drilling & boring machines, applicable to machines with a maximum boring diameter from 250 mm to 1000 mm, of both work spindle head fixed type and moving type. The machines are classified into two structural types: fixed type with integral bed and moving type with split high-low bed. The parameter table lists series of maximum boring diameter, maximum boring depth, and maximum drilling diameter. This standard replaces JB/T 8646—1997, with main changes including adjustment of the scope, addition of type descriptions, and inclusion of the 250 mm diameter specification.
本标准规定了重型深孔钻镗床的型式和参数，适用于最大镗孔直径250 mm至1000 mm的工件主轴箱固定型和移动型机床。机床分为整体床身的固定型和分离式高低床身的移动型两种结构。参数表列出了最大镗孔直径、最大镗孔深度和最大钻孔直径的系列规格。该标准替代了JB/T 8646—1997，主要变化包括调整适用范围、增加型式说明和补充250 mm规格参数。

JB/T 8332 的本部分规定了重型深孔钻镗床的型式与参数。
本部分适用于新设计的最大镗孔直径250 mm～1 000 mm、工件主轴箱固定型和移动型一般用途的重型深孔钻镗床。
本部分涉及的机床，按其结构分为两种型式：a）工件主轴箱固定型，采用整体床身，如图1所示。b）工件主轴箱移动型，采用分离式高低床身，如图2所示。
机床的参数宜符合表1的规定。
最大镗孔直径d：250, 320, 400, 500, 630, 800, 1 000；最大镗孔深度L：12 000, 15 000, 20 000；最大钻孔直径d1：100, 150。
This part of JB/T 8332 specifies the types and parameters of heavy duty deephole drilling & boring machines.
This part applies to newly designed general-purpose heavy duty deephole drilling & boring machines with a maximum boring diameter of 250 mm to 1 000 mm, of the work spindle head fixed type and moving type.
The machines covered in this part are divided into two types according to their structure: a) work spindle head fixed type, using an integral bed, as shown in Figure 1; b) work spindle head moving type, using a split high-low bed, as shown in Figure 2.
The parameters of the machine should conform to the provisions of Table 1.
Maximum boring diameter d: 250, 320, 400, 500, 630, 800, 1 000; maximum boring depth L: 12 000, 15 000, 20 000; maximum drilling diameter d1: 100, 150.
