ICS25.080.50 Machinery Industry Standard of the People's Republic of China JB/T7422.1-1999 Vertical Internal Grinding Machine Published on 1999-05-20www.bzxz.net National Bureau of Machinery Industry Implemented on 2000-01-01 JB/T7422.1—1999 This standard is revised on the basis of JB3719--84 "Vertical Internal Grinding Machine Parameters". This standard is consistent with the technical content of JB3719-84, only the standard name is changed to "Vertical Internal Grinding Machine Parameters" according to JB/T5603-91 "Vertical Internal Honing Machine Series Spectrum", and it is re-edited according to relevant regulations. This standard is part of the series of standards for vertical internal grinding machines, which include the following three parts: JB/T7422.1—1999 Parameters of vertical internal grinding machines JB/T7422.2—1999 Accuracy inspection of vertical internal grinding machines JB/T7422—1994 Standards supporting this standard include: Technical conditions for vertical internal grinding machines JB/T5603—1991 Vertical internal grinding machines JB/T9896-1999 Grinding head parameters This standard replaces JB3719—84 from the date of implementation. Series spectrum This standard is proposed by the National Technical Committee for Standardization of Metal Cutting Machine Tools. This standard is under the jurisdiction of the Boring and Drilling Machine Branch of the National Technical Committee for Standardization of Metal Cutting Machine Tools. The responsible drafting unit of this standard is Dahe Machine Tool Factory. This standard was first issued in 1984. 1 Scope Machinery Industry Standard of the People's Republic of China Vertical Internal Grinding Machine This standard specifies the parameters of vertical internal grinding machines. Parameters This standard applies to newly designed general-purpose vertical internal grinding machines. 2 Parameters The type of vertical internal grinding machine is shown in Figure 1. The parameters of the machine tool should comply with the provisions of Table 1. Figure 1 National Machinery Industry Bureau approved JB/T7422.1-1999 on May 20, 1999 Replaced JB3719-84 Implementation on January 1, 2000 Maximum ring hole diameter Grand hole depth JB/T7422.1-1999 Spindle span Maximum hole diameter Maximum taper hole depth Spindle span Note: The maximum abrasive hole diameter D is the maximum blind hole capacity of abrasive oilstones with green silicon carbide abrasives, ceramics or resin bonds for machining medium tensile strength steel under legal and reasonable use conditions.
