TJR Worm Gear Dual Arm Rotary Table

Heavy-duty dual arm support. Precision worm gear drive. Built for large workpiece CNC machining.

Overview

The TJR Worm Gear Dual Arm Rotary Table is a heavy-duty 5th-axis CNC Rotary Table.

It is designed for machining heavy or imbalanced workpieces that require support on both ends of the rotary axis. The dual arm design provides a tailstock support in addition to the drive head. This significantly increases rigidity. Reduces deflection under the cutting forces generated when machining large parts. The TJR Worm Gear Dual Arm Rotary Table is powered by a precision worm gear drive. These operations are commonly found in aerospace, heavy engineering, energy and industrial equipment manufacturing. SPT Engineering is the TJR Rotary Table dealer. They supply the Dual Arm Worm Gear Rotary Table range with full technical support.

The dual arm design supports the workpiece on both sides of the axis. This dramatically reduces bending moment and deflection during machining. This is critical for large shafts, flanges and heavy workpieces. A single-arm rotary table would flex under cutting loads and compromise accuracy in these cases.
The precision worm gear transmission delivers angular indexing. It also provides holding torque and consistent positioning accuracy. The self-locking nature of the worm gear ensures the table stays firmly in position during machining operations. This is done without relying on the hydraulic clamp.
The hydraulic clamping system on the TJR Dual Arm Worm Gear Rotary Table provides high clamping torque on the drive axis. This locks the workpiece securely during cutting. Combined with the tailstock support, the entire workpiece assembly is held rigid from both ends. This provides machining stability.
The Dual Arm CNC Rotary Table is designed to accommodate workpieces that are too long or too heavy for a standard single-arm rotary table. The extended between-centres distance and robust frame construction make it a reliable solution for industrial machining applications.

Frequently Asked Questions

A Worm Gear Dual Arm Rotary Table is a one-axis CNC Rotary Table. It supports the workpiece at both ends of the axis. It uses a head on one side and a tailstock support on the other. You need one when your workpiece is too long, too heavy or too imbalanced. A single-arm rotary table alone cannot safely and accurately hold it. The dual arm design dramatically reduces deflection and bending moment. This ensures the workpiece stays rigid during machining. Your part comes out accurately under heavy cutting conditions.
When a large workpiece is held at one end by a standard single-arm rotary table, cutting forces create a bending moment. This causes the free end of the workpiece to deflect slightly. Over the length of a part, even a small deflection creates dimensional errors in the finished component. The TJR Dual Arm Worm Gear Rotary Table eliminates this. It supports the workpiece from both ends, creating a stiffer setup. The result is dimensional accuracy. It also provides surface finish and longer tool life. The cutting geometry stays consistent throughout the operation.
The TJR Worm Gear Dual Arm Rotary Table is ideal for shafts. It is also suitable for flanges, rollers, spindle housings, large gear blanks and energy sector components. Any workpiece where the length-to-diameter ratio makes single-arm support impractical can use this table. It is widely used in engineering, power generation, oil and gas, aerospace structural components and industrial equipment manufacturing. SPT Engineering can review your workpiece dimensions. They can recommend the Dual Arm model from the TJR range.
The precision worm gear drive in the TJR Dual-Arm Rotary Table is well suited to heavy-duty applications. This is due to its self-locking characteristic and high gear ratio. The self-locking worm prevents backdriving under cutting loads. This adds a safety layer on top of the hydraulic clamp. The high gear ratio allows the drive motor to generate holding torque. This is done without oversizing the motor itself. This makes the TJR Precision Worm Gear Rotary Table a reliable and cost-effective drive choice. It is suitable for fourth-axis machining operations.
Yes. TJR Dual Arm Worm Gear Rotary Tables are designed for integration with horizontal CNC machining centres. They are compatible with control systems. These include Fanuc, Siemens and Mitsubishi. The tailstock arm is adjustable along the machine table axis. This accommodates workpiece lengths within the specified range. SPT Engineering provides pre-sales consultation. They confirm that the selected TJR Rotary Table model fits your machine's table dimensions, drive interface and control requirements.
