About CDRG 45 Roll Thread Machine

CDRG-45 Roll Thread Machine

CDRG-45 Roll Thread Machine Manufacturer & Supplier in India | Rebar Threading Machine

The CDRG-45 Roll Thread Machine is a semi-automatic rebar threading machine designed to prepare TMT bars for mechanical rebar coupler connections. It uses a rib-stripping and thread-rolling process to form a parallel thread on the prepared end of the reinforcement bar.

Unlike conventional cutting-based threading, the rebar end is prepared and then thread rolled to produce a controlled threaded section for connection with a compatible rebar coupler. This makes the machine suitable for reinforcement fabrication yards, construction projects, infrastructure work, and mechanical splicing applications.

Surya Engineering manufactures and supplies rebar threading and roll-threading equipment in Mumbai, Maharashtra, with solutions for construction contractors, reinforcement processors, fabrication companies, and industrial projects across India.

CDRG-45 Roll Thread Machine Quick Overview

*Specifications can vary by manufacturer, machine configuration and supplied model. Confirm the final technical specification before publishing it as a fixed product specification.

What is a CDRG-45 Roll Thread Machine?

A CDRG-45 Roll Thread Machine is a specialized machine used to create threaded ends on reinforcement bars for mechanical splicing with rebar couplers.

The basic process involves:

TMT Bar Rib Stripping End Preparation Thread Rolling Threaded Rebar Coupler Connection

The machine is therefore useful when a construction project requires mechanical rebar connections instead of relying only on conventional lap-splicing arrangements.

Current technical listings describe CDRG-45 machines as equipment for processing approximately 1640 mm reinforcement bars, with examples using around 62 rpm shaft speed, 5.5 kW motor power and up to 80 mm working length. Other CDRG-45 configurations publish different ranges, so machine-specific specifications should always be confirmed.

How Does the CDRG-45 Work?

The CDRG-45 prepares the end of a TMT bar so that it can accept a compatible mechanical coupler.

1. Bar Positioning

The reinforcement bar is positioned and aligned in the machine according to the required bar diameter.

2. Rib Stripping

The ribs at the required end section are removed to create a suitable cylindrical surface for thread formation.

3. Thread Rolling

The prepared section passes through the threading rollers. The rollers form the required parallel thread profile on the bar.

4. Thread Inspection

The finished thread can be checked using appropriate gauges or the specified coupler to verify compatibility.

5. Mechanical Coupling

The threaded rebar end is connected to a compatible mechanical rebar coupler according to the project's approved connection procedure.

Key Features of CDRG-45

Rebar Threading for Mechanical Splicing

The machine is specifically intended for preparing reinforcement bars for mechanical coupler connections, making it suitable for projects using mechanical splicing systems.

Rib Stripping and Thread Rolling

The combined preparation and rolling process creates the threaded section required for the compatible coupler system.

1640 mm Rebar Processing

Common CDRG-45 specifications list a processing range of approximately 1640 mm, covering several commonly used reinforcement-bar diameters.

Semi-Automatic Operation

The CDRG-45 is generally listed as a semi-automatic machine, providing a practical balance between operator control and production efficiency.

Heavy-Duty Construction

Published CDRG-45 specifications show machine weights in the region of several hundred kilograms, reflecting a machine intended for industrial and construction-site use rather than light workshop threading.

Electrical Operation

Common configurations use a 415 V three-phase electrical supply, making the machine suitable for industrial electrical installations.

Applications of CDRG-45 Roll Thread Machine

The CDRG-45 can be used for reinforcement preparation in:

• High-rise building construction

• Residential and commercial construction

• Bridges and flyovers

• Metro and railway projects

• Highway and infrastructure projects

• Industrial buildings

• Power and utility projects

• Precast construction

• Reinforcement fabrication yards

• Steel processing and rebar fabrication facilities

• Projects using mechanical rebar couplers

Mechanical rebar threading machines are particularly relevant where reinforcement bars need prepared threaded ends for coupler-based connections.

Advantages of CDRG-45 Rebar Threading

Reduced Dependence on Lap Length

Mechanical splicing can reduce the need for conventional overlapping arrangements in applications where an approved mechanical connection system is specified.

Better Reinforcement Planning

Threaded mechanical connections can provide greater flexibility when reinforcement congestion, bar continuity or connection locations need to be carefully managed.

Consistent Thread Formation

A dedicated roll-threading machine provides a controlled process for producing threaded ends when operated with the correct tooling, settings and inspection procedure.

Suitable for Repetitive Production

The semi-automatic configuration makes the machine appropriate for reinforcement fabrication operations where multiple bars require the same type of preparation.

Compatible With Rebar Coupler Systems

The machine is designed around the preparation of threaded reinforcement ends for compatible mechanical couplers. The exact thread profile, diameter and pitch must match the approved coupler system.

CDRG-45 vs Conventional Rebar Connection

The CDRG-45 is not simply a general-purpose metal threading machine. Its main construction application is preparing reinforcement bars for mechanical splicing.

The suitability of either connection method depends on the structural design, applicable project specification, approved coupler system and relevant engineering requirements.

Why Choose Surya Engineering?

Surya Engineering supplies construction and reinforcement-processing equipment for industrial and infrastructure applications.

For the CDRG-45, customers can discuss their bar diameter, required thread specification, coupler system, production requirement, electrical supply and application before selecting the machine configuration.

This is particularly important because CDRG-45 listings in the market are not completely standardized; published specifications vary between suppliers. For example, one current listing specifies 1640 mm capacity, 80 mm threading length and 5 HP motor power, while another lists 1640 mm, 80 mm working length and 5.5 kW power.
