This part is C-Shape / Slotted Antenna Shield, used in Oil & Gas Downhole Tools (MWD / LWD) as Antenna Signal Shielding and Directional Window Assembly, is a Structural-Functional Integrated Components in High-End Industrial Equipment.
Key Technical Challenges
Thin-walled + multi-grooved → extremely poor machining rigidity
All grooves are on a cylindrical curved surface
Multiple features share a common datum
MH Manufacturing Solution
● Using a five-axis machining center, complete the following in a single setup:
√ External diameter finishing
√ Establishment of internal hole and end face datum
√ Multiple axial long grooves on cylindrical curved surface
√ Groove end fillets, chamfers, and transition structures
√ Mounting hole/threaded hole positioning machining
√ Completely avoid cumulative errors caused by multiple setups.
● Dedicated process solutions for thin-walled cylinders
√ Internal support/customized clamping solutions
√ Symmetrical machining, staged stress release
√ Small depth of cut, highly stable cutting parameters
√ Optimized sequence of groove machining and external diameter finishing
● True five-axis continuous interpolation capability for groove machining
● Long-term OEM batch stability
√ Fundamental process route
√ Program version control
√ Dedicated tooling reuse
