015 Precision CNC Machined Aluminum Multi-Cavity Structural Part
CNC Milling of Precision CNC Machined Aluminum Multi-Cavity Structural Part | Case 015
This technical case study demonstrates advanced CNC milling capabilities for a custom Aluminum 7075 multi-cavity structural component. The engineering setup managed complex deep cavity side-hole machining, cavity structural rigidity control, and strict drawing-based dimensional metrology inspection. The complete batch is specified for industrial post-machining bead blasting and anodizing to support ruggedized automated equipment assembly applications.
Project Introduction
This recurring industrial program involves a precision Aluminum 7075 multi-cavity structural part executed entirely via multi-axis CNC milling centers. The geometry incorporates deep square pockets, internal side-hole machining interfaces, multi-surface datum features, and thin-walled structural boundaries for high-stability industrial assemblies.
The primary engineering focus was managing tool rigidity and deflection during deep cavity internal milling and side-hole processing. Extended tool overhangs escalate chatter and dimensional drift risks. Through feed optimization, rigid workpiece fixturing, and drawing-based stepchecks, our shop supported this repeat-order batch with zero geometric deviation.

CNC Milling Production Feasibility Highlight
Deep Cavity Side-Hole Machining
Enforces precise tool rigidity tracking, step cutting reduction paths, and active vibration mitigation to ensure side-hole concentricity and relative position accuracy.
Pocket Geometry Stability
Multi-cavity layouts require robust fixture damping, custom stress-relieving machining toolpaths, and overall flatness tracking to achieve zero assembly friction.
7075 Aluminum Optimization
High-strength Aluminum 7075 is meticulously processed for structural projects demanding superior fatigue resistance, clean thread engagement, and geometric stability.
Drawing-Based Inspection
Components undergo inline quality tracing according to technical blueprint rules, implementing targeted data monitoring across critical internal pocket coordinates.

Case 015 Manufacturing & Technical FAQ
Q1: What specific machining challenge was overcome in this cavity case?
This part requires precise deep cavity side-hole boring, where sustaining tool axis rigidity, establishing optimized stepdowns, and minimizing long-overhang vibrations are vital to block hole positional shift.
Q2: Can your facility support post-machining chemical processing for aluminum?
Yes. Fine glass bead blasting and uniform Type II clear/color anodizing are completely coordinated under unified in-house quality checkpoints to secure perfect surface texturing.
Q3: Do your engineers perform default drawing-based gate tracking?
Yes. Every feature is verified based on customer drawing specifications. Critical linear bands down to ±0.005mm are tracked at structured intervals during active tool cycle runs.
Q4: What raw material profiles are active inside your machine shop?
We execute contract machining across aluminum grades, stainless steel, free-cutting brass, structural carbon steels, copper alloys, and high-performance polymers (PEEK, Delrin POM).
Q5: Does FIWOK accept custom small-to-medium (SME) batch milling orders?
Yes. We provide complete manufacturing scalability, accommodating single prototyping runs at MOQ 1 up to long-term recurring batch schedules from 10 to 10,000+ pieces.
Q6: Are your metrology systems capable of handling specialized 3D CMM data?
Our lab explicitly does not operate corporate CMM, EDM, or grinding machine lines. Quality verification is managed using high-precision digital height encoding lines, 2D projectors, and micrometers.
