Product Details

LD4B series vertical NC turret adopts the working principle of worm wheel and worm for driving, 3 pieces face gear coupling as fine indexing mechanism, big screw for clamping,sending signal with Hall unit. It features steady rotating, indexing without tool-holder disk lifting. It is as popular product for NC lathe. The nc turret is an essential component in CNC machining, designed to efficiently hold multiple tools. A 4-station tool turret or quad turret lathe allows quick tool changes during machining. The 4 station automatic tool turret enhances productivity by automating the process. A turret tool post is commonly used in an nc lathe, providing precision in tool positioning. In modern CNC systems, the turret in cnc machine or tool turret in cnc is a crucial element for streamlining operations. Understanding what is turret in cnc machine is key to optimizing machine tool performance.

1. Confirm various parameters when choosing models of turret. Choose the number of stations according to quantity of part procedure and complicacy.

2. Choose tool specifications according to model of machine tool and cutting force. Choose the front type or rear type tool turret according to the cutting directions of the machine tool.

3. After the mounting of boring cutter seat of horizontal turret, Self-bore the inner hole according to the size of boring bar and make a corresponding mark. The tool should be fixed in the former position in the later mounting.

4. The distance tool reaching out of upper housing distance is usually not more than 2/3 upper housing size. Please note when placing an order,if more than the limit.

5. Touch by hand or other things is forbidden when turret is running to avoid injury or damage.

6. If customers have any special requirements or changes in parameters, please offer some data and contact with our company.

Why Choose the 4 station automatic tool turret?

4-Station Automatic Tool Indexing

The 4 station tool turret provides four indexed tool positions, making it suitable for CNC lathes performing common turning operations with a limited but frequently used tool set.

It is particularly suitable where the machining cycle requires automatic switching between tools without using a larger multi-station turret.

Worm Gear Drive for Stable Rotation

The 4 station automatic tool turret uses a worm wheel and worm transmission structure to drive turret rotation. This structure supports controlled indexing between tool positions and is well suited to economical and general-purpose CNC lathe configurations.

Three-Piece Face Gear Precision Indexing

A three-piece face gear coupling is used as the fine indexing mechanism. Together with screw clamping, this helps maintain consistent positioning after each tool change.

No Tool Disk Lifting During Indexing

The 4 station automatic tool turret design indexes without lifting the tool-holder disk, helping simplify the indexing movement and maintain stable turret operation.

Hall Sensor Position Feedback

Tool position signals are transmitted through a Hall sensing unit, allowing the turret position to be integrated with the CNC control sequence.

How to Select the Correct 4 station CNC turret

1. Confirm the Turret Center Height

Center height is one of the first parameters that should be matched with the CNC lathe structure.

The LD4B range currently covers:

51 / 57 / 70 / 81 / 120 / 121 / 145 mm

Do not choose a turret only according to the nominal lathe model. Confirm the actual installation dimensions before ordering.

2. Check Required Cutting Torque

For heavier turning, larger tools or higher cutting forces, select a model with sufficient tangential torque.

The LD4B series ranges from 200 N·m to 1900 N·m, so the required cutting load should be considered together with machine size.

3. Confirm Front or Rear Turret Installation

The correct turret orientation depends on the cutting direction and machine layout. Drake's existing technical guidance also recommends confirming whether a front-type or rear-type turret is required according to the machine tool configuration.

4. Check Mounting Dimensions

The current LD4B range has different values for:

H1–H4
L1–L4
A / A1
B / B1
C / D / D1
Mounting hole diameters
Thread specifications

For replacement projects, these dimensions are often more important than simply matching the model name.

5. Confirm Tool Overhang

Drake's current technical instruction recommends that the tool extension beyond the upper housing generally should not exceed approximately two-thirds of the upper housing dimension. If the application requires a longer overhang, this should be confirmed before ordering.
