CNC Large-Part Machining and 5-Axis Milling
BBG Group
Large Components. Complex Geometries. Precise Machining.
BBG provides CNC machining for large and complex parts, prototypes, low-volume production, and project-based machining. On our high-performance machining centers, we manufacture workpieces up to 158 x 79 x 47 in. (4,000 x 2,000 x 1,200 mm).
- Machining envelope: up to 158 x 79 x 47 in (4.000 x 2.000 x 1.200 mm)
- Workpiece weight: up to 33,000 lbs (15.000 kg)
- Machining capabilities: 3+2-axis- and 5-axis simultaneous machining
For complex geometries, we offer both 5-axis simultaneous and 3+2-axis machining. Our focus is on complex steel and aluminum components and free-form surfaces with demanding geometry and accuracy requirements.
With our background in tool and machine building, we bring more than CNC machining capacity to a project. Our experience manufacturing complex tooling, production equipment, and specialized custom components allows us to approach challenging CNC-Machining Projects with a strong understanding of geometry, manufacturability, and the requirements of project-based manufacturing.
5-Axis Machining for Complex Components
Depending on the geometry and technical requirements of each part, we select the most suitable machining strategy.
5-axis simultaneous machining enables precise machining of complex contours and free-form surfaces. For parts requiring machining on multiple sides or at different angles, our 5- and 6-axis machines also allow efficient 3+2-axis machining with minimal setups.
Our range of services includes:
- complex parts and prototypes
- low-volume production and project based machining
- large-part machining of steel and aluminum
- 3D geometries and free form surfaces
- tooling nd machine components
- high precision one-off parts
From 3D Data to Finished Parts
You provide us with your 3D data and technical requirements. Our manufacturing specialists review your project for manufacturability and determine the most suitable machining strategy.
We manufacture directly from your CAD data, for example in STEP format. A dedicated point of contact supports your project from data transfer and machining planning through final inspection.
Need Additional Machining Capacity?
Whether your in-house machines are fully utilized or a part exceeds your available machining envelope, BBG can provide additional capacity as a flexible contract machining partner.
We support both complete manufacturing projects and individual machining operations, allowing you to supplement your own manufacturing capabilities when additional capacity or larger machining equipment is required.
Additional Manufacturing and Assembly Services
Upon request, we can provide additional manufacturing services beyond CNC machining. Depending on the project, these may include:
- grinding
- surface treatments and coatings
- heat treatments
- mold spotting and fitting
- assemply
- additional machining and finishing operations as required
This allows customers to consolidate multiple manufacturing steps with BBG and receive parts finished to their specific project requirements.
CNC Machining Across Industries - Confidential and Reliable
Our manufacturing capabilities are available to customers across a wide range of industries, including industrial machinery and equipment, tooling and mold making, automotive, aerospace, and defense.
We understand the importance of protecting CAD data, technical drawings, and project information, particularly for technically demanding and proprietary projects. If required, we work under a non-disclosure agreement (NDA).
