Coupler Threading Machine

Coupler Threading Machine

Leo Industries manufactures coupler threading machines designed for fast, accurate, and repeatable rebar threading used in mechanical splicing systems. A coupler threading machine prepares straight, clean threads on TMT bars so couplers can achieve secure engagement and consistent load transfer. Built for workshop production and site deployment, our machines focus on stable clamping, controlled cutting, and smooth chip removal to maintain thread quality across long runs. With robust construction and operator-friendly controls, the system supports infrastructure work where productivity, alignment, and reliable splice performance are essential.

Working Principle & Process Flow

The threading cycle starts by cutting the bar end square and removing surface scale as needed. The rebar is then clamped in a rigid chuck while the die head aligns with the bar axis. As the drive rotates, the cutting dies progressively form the thread to the required pitch and length. Cutting fluid helps reduce heat and improves finish, while chips are guided away from the threading zone. Once the target thread length is achieved, the die head reverses to release, and the completed thread is verified using gauges for quick quality confirmation before coupler assembly.
