CNC Machining For Booster K1 Humanoid Robot Project Overview

Manufacturing Scope
Our team manufactures a wide range of CNC-machined components used throughout the K1 robot body.
These include:
- Robot joint components
- Joint housings
- Arm and leg components
- Structural parts
- Connecting links
- Brackets and mounting parts
- Customized mechanical housings
- Other precision CNC components
Because these parts are integrated into the same robotic system, dimensional consistency between components is important for assembly and movement.
CNC Machining for Complex Robot Components
Humanoid robot components often have irregular geometries, multiple machining surfaces, holes, curved features, and tight assembly interfaces.
For different K1 components, our engineers select suitable machining methods based on the part geometry and drawing requirements.
Depending on the component, production may involve 3-axis or 5-axis CNC machining, drilling, milling, deburring, surface finishing, and dimensional inspection.
For parts with complex multi-sided features, 5-axis machining can reduce the number of setups and improve positional consistency between different surfaces.
From CAD Drawing to Finished Part
The manufacturing process starts with the customer's 2D drawings and 3D CAD models.
Before machining, our engineering team reviews the part structure and manufacturing requirements, paying attention to:
- Critical dimensions and tolerances
- Hole positions and interfaces
- Tool accessibility
- Thin-wall or complex features
- Machining orientation
- Surface finish requirements
- Assembly-related dimensions
This engineering review helps us select an appropriate machining process before production begins.
Materials and Finishing
Different components require different material and finishing specifications.
For robot components, JCTOP has experience machining materials including:
- Aluminum
- Stainless steel
- Titanium
- Engineering plastics
Depending on the customer's requirements, CNC-machined parts can also proceed to suitable surface treatment and finishing processes before final inspection.
Quality Control
For a humanoid robot, individual components need to fit together accurately during assembly.
JCTOP performs dimensional inspection according to the customer's drawings and specifications. Critical dimensions, hole locations, interfaces, and other functional features are checked before shipment.
Our production and inspection teams work together to maintain consistency across different components and production batches.

Approximately 80% of K1 Body Components
One of the key aspects of this project is the manufacturing scope.
Rather than supplying only one specific component, JCTOP manufactures approximately 80% of the K1 body components, covering parts from different areas of the robot.
This requires us to manage different part geometries, materials, machining methods, tolerances, and production requirements within the same robotic platform.
It also gives our engineering team practical experience with the manufacturing requirements of humanoid robot mechanical systems.

Supporting the Development of Humanoid Robots
The development of a humanoid robot requires many customized mechanical components to work together as one system.
For these projects, CNC machining provides flexibility for complex geometries, design revisions, prototypes, and low-volume production.
Through our work on Booster K1, JCTOP has developed experience in manufacturing a broad range of mechanical components for humanoid robot platforms.
