YDTech® manufacturer of Centered face drive pins for CNC lathe and Turning center! supplier of central tungsten driving pins for automatic lathe or cylindrical grinder!

your Trusted Manufacturer of Central Drive Pins – Precision Engineered to Your Exact Requirements.

As a specialized manufacturer of Central Drive Pins, we understand that off-the-shelf solutions do not always fit real-world production demands. Every workpiece, every machine, and every application presents unique challenges. That is why we have built our manufacturing process around flexibility, precision, and customization.

Central Drive Pins are distinguished by their unique geometry where the contact point aligns with the center of the driving circle. This design delivers vertical and uniform force distribution, making them the ideal choice for thin-walled parts, soft metals, heat-treated components, and finished end-face workpieces where surface protection is critical. However, standard pin dimensions may not always match your specific workpiece diameter, end-face contour, or required gripping circle.

We Manufacture to Your Data – Not Just to Catalogs We offer three flexible ways to get the exact Central Drive Pins you need:

From Your Sample – Do you have an existing pin that works for your application but is no longer available or needs improvement? Send us the sample. Our engineering team will reverse-engineer it with precision measuring equipment and reproduce it exactly – or better.

From Your Drawing – Whether you provide a hand sketch, a 2D CAD file, or a full 3D model, we manufacture to your specified dimensions, tolerances, tip angles (60°, 90°, 120°), and material requirements. Our carbide tips are available in multiple grades to match your workpiece hardness and cutting conditions.

From Your Model Number – If you currently use a specific brand or model of face driver, simply provide the manufacturer's model number or part number. Our cross-reference database allows us to produce a direct replacement with identical geometry and improved wear life.

Applicable Workpieces for Central Drive Pins

Workpiece Type	Explanation
Thin-walled sleeves	Uniform force distribution on the end face prevents deformation
Precision shafts	High surface finish requirement; avoids marking or indentation
Heat-treated workpieces	High hardness; aggressive pin penetration is not suitable
Soft metal workpieces (e.g., aluminum, brass, copper)	Prevents crushing or scratching of the end face
Finished or semi-finished parts with machined end faces	Protects already-machined surfaces from damage
Gear blanks (finish turning stage)	Requires uniform clamping force to ensure gear tooth accuracy

Applicable Machines / Equipment for Central Drive Pins

Machine Type	Term	Description
CNC Lathe	CNC Lathe	Most common application; works with a tailstock center to provide axial driving force.
Turning Center	Turning Center	Suitable for high-precision, multi-operation machining.
Automatic Lathe	Automatic Lathe / Swiss-Type Lathe	Used for high-volume production of small to medium precision parts.
Cylindrical Grinder	Cylindrical Grinder	Drives the workpiece during grinding operations;
Gear Cutting Machine	Gear Cutting Machine (pre-turning stage)	Provides precise positioning and a reliable datum for subsequent gear machining (e.g., hobbing, shaping).
Multi-Spindle Lathe	Multi-Spindle Lathe	Used in high-efficiency production lines where uniform force distribution is critical.
Vertical Lathe	Vertical Lathe / VTL (Vertical Turret Lathe)	For large-diameter thin-walled parts; Central pins reduce risk of end-face crushing due to gravity and clamping forces.
