SLN-PHC Hydraulic Tool Holder for Automatic Lathes
The SLN-PHC series is a compact hydraulic tool holder for automatic lathes and sliding-headstock machines. It is used for small-diameter turning, drilling and tool holding applications where stable clamping, narrow-space access and repeatable tool changes are required.
Send the automatic lathe model, tool shank diameter, tool zone space and machining process, and we will help check the suitable SLN-PHC holder model.
Product Overview
SLN-PHC hydraulic tool holders are designed for automatic lathe applications where cutting tools must be clamped securely in limited machine space. The series supports 3–8 mm tool shanks and uses a compact holder body for quick tool replacement, stable holding and reduced vibration during machining.
The SLN-PHC series belongs to CNC tool holders and is used for holding cutting tools on automatic lathes. It is not a workholding chuck for clamping workpieces.

Dimensions and Clamping Notes
The SLN-PHC holder uses a compact hydraulic clamping structure for tool shanks from 3 mm to 8 mm. The cutting tool shank should be within h6 tolerance, and the insertion depth should not be less than C1.
Do not clamp cutting tools with a flat on the shank. Do not operate the holder without a cutting tool inserted.
Selection Notes
- Choose the holder according to machine tool space, shank diameter and required tool projection.
- Confirm φD and holder body diameter before installation.
- Use C1 and C values to confirm insertion depth and tool engagement.
- Avoid using cutting tools with flat Weldon-style shanks in this holder.
- For automatic lathe projects, provide machine model, tool shank diameter and machining process when sending an inquiry.
FAQ
What is the SLN-PHC hydraulic tool holder for automatic lathes used for?
It is used to clamp cutting tools on automatic lathes and similar machine tools that require compact hydraulic toolholding. It is suitable for turning-related auxiliary toolholding and precision machining setups where stable clamping is required.
What spindle or machine interface should be confirmed?
Please confirm the machine model, turret or tool station interface and the holder installation dimensions before selection. The holder must match the actual automatic lathe mounting structure.
What tool shank or clamping size should be checked?
Please confirm the cutting tool shank diameter, clamping length and tool overhang. These dimensions determine whether the SLN-PHC holder is suitable for the required setup.
How is this holder different from standard BT, HSK or SK CNC tool holders?
This series is intended for automatic lathe applications and should be selected according to the machine-side mounting structure. BT, HSK and SK hydraulic tool holders are used with different spindle interface systems on machining centers.
What runout, clamping stability or speed requirement should be confirmed?
Please confirm the required machining accuracy, clamping stability, spindle speed and tool overhang. These factors affect hydraulic holder selection and process suitability.
Is it a workholding chuck or a tool holder?
It is a CNC tool holder for cutting tools, not a workholding chuck for clamping workpieces. It should be selected according to the toolholding interface and cutting tool requirements.
What should be checked before installation?
Check the automatic lathe interface, holder size, tool shank diameter, mounting clearance and tightening condition before installation. The contact surfaces should be clean and free from damage.
What information is needed for quotation?
Please provide the machine model, holder interface, tool shank diameter, clamping length, machining process and any speed or clearance requirement.
