Instalação do ascensor da mesa rotativa de 5 eixos: furos profundos de corte de fio de EDM com acabamento de superfície Ra≤0.2μm

We developed a high-accuracy 5-axis rotary table riser fixture for a European aerospace component manufacturer. The fixture increases rotary table height by 120mm, enabling machining of complex special-shaped parts. Manufactured with slow wire EDMeultra-finish surface grinding, it achieves sub-micron flatness and parallelism, directly determining the final machining accuracy of fixtured parts.

Visão geral do projeto

Principais destaques técnicos

• Slow Wire EDM for Deep Holes: Achieved 0.003mm straightness over 100mm depth using multi-pass wire EDM with tension control, eliminating drill deflection common in traditional machining.
• Mirror-Finish Surface: Ultra-precision grinding + lapping delivers Ra≤0.2μm on all mating surfaces, ensuring maximum contact rigidity and repeatable clamping accuracy.
• Thermal Stability: Stress-relieved and cryogenic treated to maintain ±0.002mm geometry across 10–40°C shop floor temperature variations.
• Modular Interface: Custom bolt pattern matches popular 5-axis tables (DS, Haas, Hermle, etc.), increasing rotary table height without rigidity loss.

Quality Verification

Every riser fixture undergoes laser interferometer flatness and parallelism inspection (0.001mm resolution), CMM verification of all hole positions, and surface profilometer measurement of critical zones. Deep hole straightness is validated via precision plug gauge and air gauging.
