aluminum parts?
A: CNC precision machining delivers significant advantages for
custom large aluminum CNC machined part manufacturing. The 5-axis
machining capability enables production of precision large complex
geometries with multi-cavity features, multi-curved surfaces,
complex angled walls, and intricate details that would be
impossible or expensive with conventional casting, fabrication, or
3-axis machining methods. The single-setup 5-axis machining ensures
perfect alignment between all features and surfaces without
requiring multiple setups or repositioning that could introduce
errors. The precision machining ensures accurate dimensional
control for proper assembly fit, reliable operation, and consistent
performance across the large part. The aluminum construction
provides lightweight for portable applications (reducing overall
system weight and transportation costs), excellent machinability
for precision features, good strength-to-weight ratio for
structural support, and superior thermal conductivity for heat
dissipation. The large-scale machining capability handles parts up
to 1500*1000*800mm or larger, enabling production of large
industrial equipment shells, complex housings, and large structural
components in single setup. The mirror-finished internal cavity
walls ensure clean professional appearance and proper sealing where
required. The in-process probing enables precision verification
throughout the manufacturing cycle, catching any deviations early
and ensuring final part accuracy. The result is superior
dimensional accuracy, complex geometry integration, and reliable
performance for large-scale aluminum part applications.
Q: What size of large aluminum parts can you manufacture?
A: We manufacture various sizes of custom large aluminum CNC
machined parts covering comprehensive size ranges: medium-large
parts (under 500mm in major dimension, for general industrial
applications), large parts (500-1000mm, for large industrial
equipment and structural components, as commonly featured in large
5-axis machining), extra-large parts (1000-1500mm, for large
industrial systems and equipment structures), oversized parts
(1500-2000mm, for heavy industrial applications and large
structural components), and custom oversized parts (2000mm+, for
specialized industrial applications and very large machinery). Our
5-axis CNC machining centers can handle parts up to 1500*1000*800mm
or larger depending on configuration. The featured design shows a
large complex part during 5-axis machining occupying a substantial
portion of the machining work area. We can manufacture parts from
medium-large industrial components to oversized industrial
equipment shells, all with the same precision 5-axis machining
quality. Various configurations and dimensions are available
including different lengths, widths, heights, multi-cavity
configurations, curved surface geometries, and feature
combinations. Custom sizes and configurations available for
specific large-scale requirements.
Q: What aluminum alloys do you use for large machined parts?
A: We work with various high-quality aluminum alloys for CNC
machined custom large aluminum CNC machined parts: 6061-T6 aluminum
(most common, excellent machinability, good strength-to-weight
ratio, ideal for general large equipment shells, structural
components, and standard applications), 7075-T6 aluminum (high
strength for load-bearing large parts, high-stress structural
applications, and aerospace-grade components), 6082-T6 aluminum
(structural grade with good corrosion resistance and weldability,
ideal for structural frames and large outdoor applications), 5052
aluminum (excellent corrosion resistance for marine, outdoor, and
harsh environment applications), and custom aluminum alloys.
Material selection depends on your structural load requirements,
environmental conditions, weight preferences, thermal management
requirements, welding needs, and size requirements. For very large
parts, 6061-T6 is most commonly used due to its excellent
machinability, good availability in large plate/billet forms, and
reliable properties. Hard anodizing (Type II or III), color
anodizing, powder coating, chromate conversion coating, and other
surface treatments can be applied for enhanced appearance,
corrosion resistance, and wear resistance. All materials come with
full material traceability certification and material certificates
per batch.
Q: What tolerances can you achieve on large aluminum parts?
A: We achieve dimensional tolerances within +/-0.01mm on critical
large part features, multi-cavity depth accuracy within +/-0.02mm,
multi-cavity width accuracy within +/-0.02mm, curved surface
accuracy within +/-0.02mm verified by 3D scanning and CMM, mounting
hole position accuracy within +/-0.05mm (for large parts, slightly
wider tolerance accounts for thermal expansion and fixturing
considerations), base flatness within 0.05mm for standard
applications and 0.02mm for precision applications, surface
perpendicularity within 0.02mm between reference surfaces, linear
dimension accuracy within +/-0.05mm for general dimensions and
+/-0.02mm for critical functional dimensions, angular accuracy
within +/-0.1 degrees, parallel within 0.03mm between reference
surfaces, surface roughness within Ra 0.05-0.1um on cavity walls
(mirror finish) and Ra 0.4-0.8um on general machined surfaces, and
overall dimensions within +/-0.1mm for standard parts and +/-0.2mm
for very large parts. Our advanced 5-axis CNC machining centers
maintain tight geometric tolerances following GB/T 1804-2000 and
ISO manufacturing standards. In-process probing during machining
ensures precision verification throughout the manufacturing cycle.
These tolerances ensure proper assembly fit, reliable operation,
and consistent quality for large aluminum CNC machined parts.
Q: What is in-process probing and how does it benefit large part
manufacturing?
A: In-process probing is a precision measurement technique where a
touch probe is integrated into the CNC machining spindle (as
visible in the featured design with precision probe/spindle shown)
to measure part features during the machining cycle. The probe
touches reference points on the part to verify dimensional
accuracy, feature positions, and geometric tolerances in real-time
without removing the part from the machine. Benefits for large
aluminum CNC machined part manufacturing include: real-time
dimensional verification (catching deviations early before they
compound), automatic tool length compensation (adjusting for tool
wear and thermal effects), automatic work coordinate system
establishment (precise part positioning), in-cycle quality control
(eliminating separate inspection steps), reduced scrap rate
(catching errors before completion), improved first-pass yield
(reducing rework and material waste), documented measurement
records (full traceability of in-process dimensions), thermal
compensation (accounting for temperature-induced dimensional
changes), and adaptive machining (adjusting tool paths based on
measured features). In-process probing is particularly valuable for
large parts where errors compound over the long machining cycle and
where post-machining correction is difficult or impossible. The
result is higher precision, better consistency, and reduced
manufacturing risk for large complex aluminum parts.
Q: What multi-cavity features can be machined into large aluminum
parts?
A: We can machine various multi-cavity features into custom large
aluminum CNC machined parts: rectangular cavities (for rectangular
component housing), square cavities (for square modules and
assemblies), circular cavities (for cylindrical components,
bearings, and round features), irregular shaped cavities (for
specific component geometries), stepped cavities (multi-level
cavity floors for different component heights), cavities with
rounded corners (stress relief design), cavities with angled walls
(draft angle for assembly or ejection), cavities with internal
bosses (raised features for component mounting), cavities with
internal ribs (structural reinforcement), cavities with internal
channels (wiring, fluid routing, or ventilation), cavities with
internal seats (for component installation), shallow cavities
(5-20mm depth for thin components), medium cavities (20-50mm depth
for standard components), deep cavities (50-100mm depth for larger
components), very deep cavities (100-300mm depth for tall
assemblies), ultra-deep cavities (300mm+ depth for very large
assemblies), cavities with through-holes (for component
pass-through), cavities with mounting features (bosses, threaded
holes, dowel pins), and complex multi-cavity configurations
(multiple cavities in single part for integrated assembly). Our
5-axis CNC machining capabilities enable production of large parts
with multiple integrated cavity features in single setup.
Q: What surface finishes are available for large aluminum parts?
A: We offer various surface finishes for custom large aluminum CNC
machined parts: mirror polished cavity walls (Ra 0.05-0.1um, for
clean professional appearance and smooth component insertion),
mirror polished exterior (premium decorative applications), fine
machined surfaces (Ra 0.2-0.4um, for improved fit and finish),
standard machined surfaces (Ra 0.4-0.8um, for general machined
surfaces), as-machined surfaces (for lowest cost general
applications), brushed finish (linear brushing for satin
appearance), bead blasted finish (matte texture for understated
elegance), clear anodizing (Type II, 5-15 microns, corrosion
protection while preserving metal appearance), hard anodizing (Type
III, 25-75 microns, 400-500 HV hardness for wear resistance), color
anodizing (black, blue, red, gold, custom colors), powder coating
(durable color finish), chromate conversion coating (electrical
conductivity preservation), and custom surface treatments per your
specifications. Surface finish selection depends on your
application requirements, functional needs, environmental
conditions, aesthetic preferences, and wear resistance
requirements. For large parts, anodizing is often preferred for
corrosion protection across the entire surface area.

Q: What is the typical lead time for large aluminum parts?
A: Prototype samples: 20-30 days (5-axis CNC programming and setup
for large complex part with multi-cavity features and curved
surfaces, including in-process probing setup). Small batch (5-20
parts): 4-8 weeks depending on part size and complexity. Medium
batch (20-100 parts): 8-14 weeks. Large production (100+ parts):
14-20 weeks. Surface treatment (anodizing, coating, plating) adds
5-10 days for large parts due to longer processing time. Fast
delivery and consistent quality ensure high customer satisfaction.
Rush orders can be accommodated upon request for urgent prototype
or production needs. Large part complexity, size, multi-cavity
configuration, curved surface requirements, feature count, and
surface treatment requirements affect production timeline. Our
