Product catalog summary

Overview
This document details the HYDRO-LINE hydraulic chuck system by PCM Willen SA, designed for Swiss-type automatic lathes. It replaces traditional collet holders with a hydraulic expansion chuck, achieving ultra-precise run-out accuracy of 0.001 mm and supporting internal coolant systems.

1. Company Presentation
PCM Willen SA, based in Villeneuve, Switzerland, has over 40 years of expertise in manufacturing special tool holders for automatic lathes. The company focuses on Swiss precision, quality, and reliability, offering tailored training, after-sales support, and close collaboration with machine builders and users.

2. Product Description and Advantages

Ultra Precision: Hydraulic chuck ensures consistent run-out accuracy of 0.001 mm T.I.R, significantly better than collet holders.
Vibration Damping: Hydraulic system reduces vibrations, extending tool life.
Easy Clamping: Simplifies tool changes and adjustments via hydraulic clamping.
Internal Coolant System: Integrated coolant channels enhance tool cooling and productivity.
Axial Length Adjustment: Allows free and easy axial length modification of tools.
Compatibility: Requires H6 tolerance shank tools; hydro-sleeves enable use of various diameters between 8 and 12 mm.
Additional Options: Special sizes/designs available on request; torque T-wrenches sold separately.

3. Technical Specifications and Dimensions
Detailed dimensional tables are provided for multiple machine brands (Citizen Cincom, Star Micronics, Tsugami, Tornos, Hanwha, Nomura DS, Nexturn) covering front and back types. Parameters include diameters (D1, D2, D3), lengths (L1 to L5), shape, wrench type (TR-3.0 or TR-4.0), and compatible machine models. Shank diameters range from 3 mm to 25.4 mm (1 inch).

4. Usage Recommendations and Limitations

Use only H6 tolerance shank tools for optimal performance.
Do not open the oil safety bolt to prevent damage.
Use the correct wrench type for clamping and maintenance.
Primarily designed for Swiss-type automatic lathes but applicable to other high-precision machines.

PRESENTATION The product is an ultra-precise cylindrical tool holder designed for Swisstype machines. These can of course also be used on all machines where extremely precise clamping of the tool is required. This tool clamping replaces the cylindrical collet holders and the clamping is done by an integrated hydraulic expansion chuck. This system drastically reduces the run-out error and the tool is clamped with a run-out accuracy of 0.001mm. In addition, the cylindrical tool holders are designed for internal cooling system to increase productivity even more. It is also possible to use this holder...
