- Scope
- This standard specifies the geometric accuracy requirements and inspection methods for horizontal and additional spindle head machine tools. This standard applies to general-purpose ordinary precision horizontal machining centers with essentially four CNC axes, including three linear axes (X, Y, Z) with strokes up to 2000mm and one rotary axis (B′), and is also applicable For additional movements associated with sliding spindles, rams or additional universal spindle heads in three different versions. The appendix of this standard lists three possible inspection items for additional universal spindle heads: Appendix A: 45° bisection indexing spindle heads (AG1 to AG9); Appendix B: Rotary spindle heads (BG1 to BG7); Appendix C: 45° bisection continuous indexing spindle head (CG1 to CG7).
