CLT Series Cam Hydraulic Turret

CLT series turret is a high-performance cam hydraulic turret designed for precision machining. This advanced CNC turret ensures efficient and stable tool changes, making it an ideal choice for various turning applications. With its robust hydraulic turret system and reliable servo turret control, it enhances machining accuracy and productivity. Whether for a lathe or a turning center, this lathe turret delivers exceptional performance in demanding industrial environments.

Its internal cam indexing mechanism provides precise positioning and rapid tool changes, while the hydraulic motor provides high driving torque. Tool release and clamping are also hydraulically operated, helping maintain reliable locking during demanding turning operations. Tool position is controlled through proximity detection and PLC programming, with nearest-tool selection supported for efficient indexing.

The CLT series is available in 8-position and 12-position configurations, with current models including CLT63, CLT80, CLT80A and CLT100. Center heights range from 63 mm to 100 mm, while maximum tangential torque reaches up to 3500 N·m, depending on model.

Optional 30 bar, 50 bar and 70 bar high-pressure coolant configurations are available for applications requiring through-tool or high-pressure cutting-fluid delivery.

Key Features of the CLT Cam Hydraulic Turret

Cam Indexing for Fast and Accurate Positioning

The internal cam mechanism provides precise mechanical indexing while reducing tool-change time. Depending on the CLT model, the current specification lists basic rotation times from approximately 0.35 to 0.65 seconds.

Hydraulic Drive with High Torque Output

Unlike economical electric turrets designed mainly for lighter turning operations, the CLT series uses a hydraulic motor for turret rotation, providing higher output torque and stable tool-changing performance.

Hydraulic Tool Release and Clamping

Tool release and turret clamping are hydraulically controlled. The rigid locking structure makes the CLT series particularly suitable for applications involving rough turning, larger cutting loads and continuous production.

8 or 12 Tool Positions

The CLT series can be configured with 8 or 12 tool stations, allowing machine builders to select the appropriate capacity according to machining complexity and the number of tools required in one production cycle.

PLC-Controlled Tool Selection

Proximity detection and PLC programming are used for position recognition and nearest-tool selection, reducing unnecessary turret rotation during automatic tool changing.

High-Pressure Coolant Options

For machining processes requiring improved chip evacuation and cutting-zone cooling, optional 30 / 50 / 70 bar high-pressure coolant configurations can be specified.

CLT Hydraulic Turret Model Selection Guide

The correct model should be selected according to center height, installation dimensions, cutting torque, tool size and the hydraulic system of the CNC lathe—not simply by turret diameter.

How to Select the Right CLT Hydraulic Turret

1. Confirm the Turret Center Height

The CLT series currently provides 63 mm, 80 mm and 100 mm center-height configurations. Center height must match the machine structure and spindle/tool centerline before installation dimensions are evaluated.

For replacement projects, do not select a CLT turret only according to the original turret's appearance. Provide the existing turret model and mounting dimensions for comparison.

2. Choose 8 or 12 Tool Stations

An 8 station hydraulic turret is suitable where the machining process uses a relatively limited number of turning, facing, grooving and boring tools.

A 12 station hydraulic turret provides more available positions for parts requiring multiple machining operations and can reduce manual tool setup between production cycles.

The CLT range supports both 8- and 12-position arrangements depending on configuration.

3. Check the Required Cutting Torque

Cutting load is especially important when selecting a hydraulic turret.

The CLT series currently lists maximum tangential torque values of:

• CLT63 — 1500 N·m

• CLT80 — 2000 N·m

• CLT80A — 2500 N·m

• CLT100 — 3500 N·m

The same listed values apply to maximum axial torque for these models.

For rough turning, larger workpieces or heavier cutting conditions, torque capacity should be checked before selecting the final turret size.

4. Confirm Hydraulic Pressure and Flow

The standard working pressure currently specified for the CLT series is 3.5 MPa, while required working flow varies by model from approximately 18 to 30 L/min.

The machine's hydraulic system therefore needs to be checked before replacement or integration into a new CNC lathe.

5.Check Tool Size

The allowable boring-tool diameter varies according to CLT model. Current specifications include options ranging from approximately Ø20 mm up to Ø50 mm, depending on model.

Before quotation, provide the maximum OD turning tool, facing tool and boring-bar dimensions planned for the machine.

6. Decide Whether High-Pressure Coolant Is Required

If the machine is intended for deep-hole machining, difficult chip evacuation or applications requiring high-pressure coolant delivery, specify this during selection.

CLT configurations can be customized for 30 bar, 50 bar or 70 bar coolant pressure.

Which CLT Hydraulic Turret Model Should You Choose?

CLT63

Choose the CLT63 when the CNC lathe requires a compact 63 mm center-height hydraulic turret and the cutting load remains within its specified torque range.

CLT80

The CLT80 provides an 80 mm center height and higher torque capacity, making it suitable for medium-size CNC turning applications requiring a balance between turret size and cutting rigidity.

CLT80A

The CLT80A also uses an 80 mm center height, but its current specification provides higher working flow and torque capacity than the CLT80. It is therefore worth considering when greater cutting-load capability is required while maintaining an 80 mm center height.

CLT100

The CLT100 is the larger configuration in the current range, with a 100 mm center height and maximum tangential torque of 3500 N·m. It is better suited to larger CNC lathe configurations and heavier cutting requirements.

Situations where reliable, durable turret performance is essential for safety and productivity.

Applications of the CLT Series Cam Hydraulic Turret

The CLT series is suitable for CNC turning applications where rapid indexing, reliable hydraulic clamping and high turret rigidity are important.

Typical applications include:

• CNC turning centers

• Medium and heavy-duty CNC lathes
