Large CNC machining plays a critical role in industries that require oversized, heavy, or highly integrated components. From structural frames to large housings and molds, working with an experienced large CNC machining supplier1 directly impacts part accuracy, delivery reliability, and overall project risk. This article explains what matters most when selecting a supplier and how Ruicheng supports large-format machining and molding projects.
What Defines a Large CNC Machining Supplier
Not every CNC shop is equipped to handle large parts. True large CNC machining2 suppliers combine oversized machine tools, skilled operators, and proven process control.
Large-part machining requires stable machine structures, precise alignment, and advanced programming to prevent deformation and tolerance drift.
Large CNC machining is typically used for:
Structural frames and bases
Large aluminum plates and panels
Heavy-duty brackets and mounts
Machine housings and enclosures
Tooling plates and industrial molds
Ruicheng’s Large CNC Machining Capabilities
Ruicheng operates as a full-scale metal manufacturing company with dedicated equipment for oversized components. Our facility includes large-format 3-axis and 5-axis CNC machines designed for long travel distances and heavy workpieces.
Our company supports both high-precision machining3 and high-load cutting for large metal parts without sacrificing dimensional stability4.
Key capabilities include:
Large CNC milling with extended X/Y/Z travel
5-axis machining5 for multi-face large components
Heavy-duty steel and aluminum machining
Stable fixturing systems for oversized parts
Full inspection using large-range CMM equipment
Large-Size Products We Have Successfully Manufactured
Experience with real-world large components is essential when evaluating a supplier. Ruicheng has delivered multiple large-format projects6 across different industries.
These projects demonstrate our ability to manage size, weight, and precision simultaneously.
Representative large-part examples include:
Aluminum equipment bases over 1.5 meters in length
Steel machine frames with multi-surface tolerances
Large stainless steel housings for industrial systems
Oversized tooling plates for automated production lines
Combining Large CNC Machining and Injection Molding
Many large projects require both machined metal components and molded plastic parts. Ruicheng offers integrated manufacturing7, combining CNC machining with injection molding under one roof.
This integrated approach reduces supplier coordination risk and improves overall assembly accuracy.
Our injection molding capabilities include:
Large plastic housings and covers
Structural plastic components
Prototype and production molds
Low- and high-volume injection molding
Materials Commonly Used in Large CNC Machining
Material selection plays a major role in large-part performance and machinability. Ruicheng supports a wide range of metals and engineering plastics8.
Each material is processed using optimized cutting strategies to minimize stress and distortion.
| Material | Key Advantages | Typical Applications |
|---|---|---|
| Aluminum alloys | Lightweight, stable, easy to machine | Frames, plates, enclosures |
| Carbon & alloy steel | High strength, rigid | Machine bases, heavy supports |
| Stainless steel | Corrosion-resistant | Industrial housings |
| Engineering plastics | Lightweight, moldable | Covers, panels, casings |
Quality Control for Oversized Components
Maintaining accuracy on large parts is more challenging than on small components. Ruicheng follows ISO 9001-certified processes9 to ensure consistent quality.
Our inspection workflow focuses on flatness, parallelism, and positional accuracy across large surfaces.
Quality measures include:
In-process dimensional checks
CMM inspection for large parts10
Surface flatness and alignment verification
Complete inspection reports upon request
Case Example — Large Aluminum Machine Base
A customer required a large aluminum machine base with strict flatness requirements for automated equipment. The part exceeded standard CNC travel limits for typical shops. Ruicheng used a large-format CNC milling center and custom fixturing to maintain rigidity during machining.
The final component met flatness requirements and reduced the customer’s on-site assembly adjustments by over 30%.
