Advanced Tool Holding Solutions for CNC Machining Applications

CNC machining has revolutionized modern manufacturing by delivering unmatched precision, efficiency, and flexibility. However, the performance of a CNC machine is only as good as its tool holding system. At KURATA Precision Tools, we provide a complete range of high-precision tool holders designed to meet the most demanding requirements across industries such as aerospace, automotive, woodworking, and precision mold making.

Our product portfolio includes Shrink Fit Tool Holders, Hydraulic Tool Holders, Engraving Machine Tool Holders, ER Collet Holders, SK Collets, Pull-Back Collets, Face Mill Holders, Heavy-Duty Tool Holders, and Grinding Wheel Arbors—each engineered for specific CNC applications.

1. Aerospace and Automotive Components

In aerospace and automotive industries, where high-speed cutting and extreme accuracy are essential, shrink fit technology has become the gold standard.

• HSK Shrink Fit Tool Holders: Deliver exceptional balance and rigidity for high-speed spindles in aerospace machining.

• BT Shrink Fit Tool Holders: Ideal for heavy-duty milling and drilling operations in automotive part production.

• BBT Shrink-Fit Tool Holders: Dual-contact interface ensures increased stability during high-speed cutting.

• Shrink-Fit Extensions: Provide extended reach for deep cavities without sacrificing precision.

These shrink fit solutions guarantee runout accuracy of ≤0.003mm, ensuring superior surface finishes and longer tool life in demanding environments.

2. Precision Mold and Die Making

Mold and die applications require ultra-accurate cuts and smooth surfaces. Our Hydraulic Tool Holders are specifically designed for finishing and semi-finishing operations where tool change flexibility and vibration damping are critical.

• Key Benefits:

• Easy tool change without shrink fit equipment

• Outstanding damping properties for superior surface finishes

• Perfect for reaming, drilling, and fine milling in mold cavities

For engraving intricate patterns or micro-cutting details, our Engraving Machine Tool Holders deliver excellent stability and repeatability, making them indispensable for engraving logos, patterns, and fine textures on molds.

3. General CNC Machining Applications

For workshops handling multiple processes, versatility is key. The ER Collet Holder is a universal solution for a wide range of machining tasks such as milling, drilling, and tapping.

• ER Collet Holders: Widely used for their flexibility and cost-effectiveness.

• SK Collets & Pull-Back Collets: Offer higher gripping force and improved accuracy for high-speed machining operations.

This combination ensures adaptability without compromising performance in general machining operations.

4. Heavy-Duty Milling and Face Milling

When aggressive material removal and rigid clamping are required, Face Mill Holders and Heavy-Duty Tool Holders are the preferred choice. These holders provide maximum stability under high torque loads, making them essential for large part machining in industries like heavy machinery and automotive manufacturing.

5. Grinding and Finishing Applications

Precision grinding requires perfect balance and concentricity. Our Grinding Wheel Arbors are engineered for high-speed grinding operations, ensuring smooth performance and excellent surface quality for finishing critical components.
