NEXABOT: INDUSTRIAL ROBOT JOINT ASSEMBLY MANUFACTURING
From 10 prototypes to 5,000 production units seamlessly
Results Achieved
Through batch optimization and manufacturing process improvements.
Lead time per batch of 200 joint assemblies.
Scaled from 60 to 5,000+ assemblies over 8 months.
NexaBot deployed 380+ industrial robots to automotive manufacturing plants across India, with the SPC data providing confidence in every delivered batch.
The Breakdown
Industry: Robotics & Automation
Why MetalMarket Technologies?
NexaBot is a Pune-based industrial robotics company scaling their 6-axis collaborative robot from lab prototype to mass production. The joint actuator assemblies required exceptional concentricity and surface finish for smooth motion control.
About The Company
NexaBot is a Pune-based industrial robotics company scaling their 6-axis collaborative robot from lab prototype to mass production. The joint actuator assemblies required exceptional concentricity and surface finish for smooth motion control.
The Challenge
Scaling from 10 robot sets to 5,000+ assemblies while maintaining micro-precision consistency was the core challenge.
- Each robot required 6 unique joint assemblies, each with 12 precision components
- Hardened steel gear housings demanded ±0.003mm tolerances
- Surface roughness below Ra 0.2μm required for bearing interfaces
- Volume scaling from 60 assemblies to 5,000+ with identical quality
Any dimensional inconsistency in joint assemblies would result in vibration, wear, and ultimately robot failure in the field — unacceptable for customers in automotive manufacturing.
The Solution
Metal Market introduced statistical process control (SPC) monitoring with real-time quality dashboards accessible through the platform, giving NexaBot confidence in the consistency of every batch.
Dedicated Production Cell
- Two synchronized facilities with coordinated scheduling
- Complete assembly kit delivery for each robot set
- Precision grinding post-process for critical bearing surfaces
Statistical Quality Control
- SPC monitoring across all production batches
- Real-time quality dashboards on the digital platform
- Cpk > 1.67 maintained consistently across all batches
- 200 assemblies per batch with 8-day cycle time
“The SPC data Metal Market provides gives us confidence in every batch. We've built our quality reputation on the consistency they deliver.”
