The TCWB-M20TG-4 is a four spindles pass through nut tapping machine designed for manufacturers who need both higher output and stable performance when tapping medium to large size nuts. It is often selected by factories that have outgrown double spindle machines and are looking to scale production without increasing labor or quality risk.
From our experience, increasing spindle quantity on large-size nut tapping is not simply a matter of adding speed. Without proper structure and control, problems such as vibration, uneven thread depth, and accelerated tool wear can quickly appear. This model was developed specifically to solve those issues.

As a manufacturer, we designed the TCWB-M20TG-4 around real production conditions rather than theoretical capacity. The four-spindle configuration allows higher throughput, while the pass through design ensures smooth and continuous nut flow.
During development, our focus was on:
Maintaining tapping stability under higher cutting torque
Keeping spindle motion consistent across all stations
Ensuring the machine can operate reliably during long production shifts
This balance makes the nut tapping machine suitable for factories that handle large batch orders with strict delivery schedules.
CNC Pass Through Nut Tapping Machine is widely used in:
Automotive fastener production
Structural construction hardware manufacturing
Industrial bolt and nut factories
High-precision export-oriented fastener plants
Smart manufacturing fastener facilities
It supports hex nuts, flange nuts, and standard industrial nut types requiring strict dimensional tolerance.
The CNC system enhances thread forming stability by providing digital control over tapping speed, feed rate, and torque.
Core technical features include:
Programmable tapping parameters
Digital spindle speed control
Stable pass through feeding mechanism
High-precision positioning system
Real-time monitoring capability
This CNC nut tapping machine ensures consistent performance across long production cycles while minimizing adjustment downtime.
We provide operation guidance and after-sales support to help customers integrate the machine smoothly. Each unit is packed in reinforced plywood packaging suitable for international transportation.
Specialized in nut tapping machine technology
Focused on precision thread processing systems
Experience serving global fastener manufacturers
