Slim Hydro Chuck PHC·S

Product catalog summary

Overview

The document details the Slim Hydro Chuck PHC・S, a slim hydraulic chuck designed for high precision and stable clamping in confined machining spaces, particularly suited for 5-axis machining centers. It also covers a series of precision tool holders compatible with various HSK tool interfaces and high-pressure coolant feed options.

Key Features of Slim Hydro Chuck PHC・S

Slim Profile: Enables machining in tight spaces without interference.
Dual Clamping Points System: Ensures stable, high-precision tool holding by engaging two points on the tool shank.
Oil Chamber for Vibration Absorption: Surrounds the chucking sleeve with high-pressure oil to dampen cutting vibrations, improving machining stability and surface finish.
Simple Operation: One-hand clamping via hex wrench for quick tool changes.
Tool Pre-Set Without Height Offset: Allows precise tool setting without additional height adjustments.
Size Range: Metric (φ6 mm to φ12 mm) and inch sizes (0.250" to 0.500") available.

Performance and Application

The chuck achieves approximately 3 μm runout accuracy, ideal for vertical machining centers using carbide end-mills with irregular pitch flutes at speeds around 4,200 min⁻¹ and feeds of 850 mm/min. The oil chamber significantly reduces vibration compared to solid metal chucks, enhancing tool life and machining quality.

Technical Specifications

Detailed dimensional data are provided for multiple tool holder standards (CAT40, CAT50, SK40, BT30, BT40, BT50, AHO30/40/50) covering:

Shank Diameter (d): 6 mm to 12 mm (metric), 0.250" to 0.500" (inch).
Projection Length (L): Various lengths (135 mm to 195 mm) to suit machining requirements.
Insertion Length (ℓ) and Minimum Clamping Length (ℓ1): Specified per model for secure tool engagement.
Other Dimensions: Internal diameters (D1-D4), angle α (typically 3°), and wrench type (usually L-4T hex wrench).

Usage Guidelines and Recommendations

Tool shank diameter must conform to h6 tolerance for proper clamping and accuracy.
Avoid tightening the actuating screw when the chuck is empty to prevent damage.
Use hex-head screws to plug air holes when employing center-through coolant feed to prevent leakage.

Ordering Information

Ordering codes are structured by shank size, model name (PHC), projection length, and internal diameter. For high-pressure coolant feed holders, add suffix "-H" to the model code. Examples are provided for each tool holder type and size to facilitate correct selection.

Additional Tool Holder Series and Compatibility

The document also covers precision tool holders compatible with HSK interfaces (HSK40A, HSK50A, HSK63A, HSK100A) and high-pressure coolant feed holders (UTS5040, UTS6350). Key points include:

Multiple models with detailed dimensional parameters (diameter, length, insertion length, angles).
Projection lengths ranging from 135 mm to 195 mm depending on model and interface size.
Compatibility with both metric and inch tool shanks.

Critical Information Summary

Tolerance: Tool shank diameter must be within h6 tolerance class.
Handling: Do not tighten actuating screw when chuck is empty.
Coolant Feed: Hex-head screws required to seal air holes for center-through coolant feed.
Ordering: Specify pressure type; add "-H" suffix for high-pressure coolant feed models.
Compatibility: Supports multiple HSK sizes with comprehensive dimensional data for precise selection.

Contact and Support

Manufacturer contact details are provided for global offices including Japan (Head Office), USA, Germany, Thailand, Indonesia, and China for sales and technical support.

Summary

The Slim Hydro Chuck PHC・S and associated precision tool holders offer advanced solutions for high-accuracy, vibration-damped tool holding in compact machining environments. Their broad compatibility with various tool holder standards and coolant feed options makes them suitable for demanding CNC machining applications, especially in 5-axis machining centers.
