Description

Technical Field

[0001] This utility model relates to the technical field of double-swivel head five-axis XYZAC machine tools, specifically a double-swivel head five-axis XYZAC machine tool. Background Technology

[0002] Traditional three-axis gantry milling machines have limited machining capabilities: they only support X / Y / Z linear motion, making it impossible to machine complex curved surfaces (such as impellers and spiral grooves) and inverted structures, requiring multiple clamping operations that lead to cumulative errors (above ±0.03mm). They are also inefficient: the number of clamping operations increases by 3-5 times, and auxiliary time accounts for over 30%, whereas five-axis machines can complete multi-faceted machining in a single clamping operation. Space utilization is low: the vertical feed of the tool creates a machining blind zone, with actual usable space less than 50% (compared to 85% for five-axis machines). Quality defects include tool marks (Ra difference ≥0.4μm) and clamping stress causing a 15% deformation rate in thin-walled parts (≤3% for five-axis machines). Economic efficiency is poor: single-piece machining time is 167% higher, fixture costs are 300% higher, and the scrap rate is more than four times that of five-axis machines. A typical impact is that in aerospace parts machining, the scrap rate for three-axis solutions is 12% (compared to only 2% for five-axis solutions), highlighting the technological gap.
