T/DLJX 0011.1-2023 Checking conditions for horizontal Y axis horizontal milling and turning composite machining center with moving column Part 1: Geometric accuracy testing

Scope

Scope: This document specifies the inspection conditions, inspection items, inspection methods, and tolerance limits for the geometric accuracy inspection of gantry-type horizontal Y-axis vertical milling and turning composite machining centers. This document applies to gantry-type horizontal Y-axis vertical milling and turning composite machining centers with a maximum rotary diameter of up to 1000mm and a linear axis travel of up to 2000mm. Machines with linear travel exceeding 2000mm can also refer to and implement this document. This document only applies to the accuracy inspection of machines, and does not apply to the operational inspection of machines (such as machine vibration, abnormal noise, and component creep) or the parameter inspection of machines (such as speed and feed rate). Main technical content: This document is divided into 5 chapters, including scope, normative reference documents, terms and definitions, general requirements, and geometric accuracy. 1) Regarding "Scope", this chapter specifies the applicable scope of the standard. 2) Regarding "Normative Reference Documents", the documents referred to in this chapter are the latest valid versions. 3) Regarding "Terms and Definitions", the terms and definitions defined in this chapter apply to this document. 4) Regarding "General Requirements", Chapter 4 "General Requirements" specifies the standards for the geometric inspection of machines, the inspection sequence, inspection items, inspection tools, diagrams, and the range of machine dimensions. 5) Regarding "Geometric Accuracy", Chapter 5 "Geometric Accuracy" specifies the specific inspection tools, methods, and inspection index requirements for the inspection items G1-G35 of the geometric accuracy of machines.
