HSK coolant tubes ensure effective coolant delivery, reduce heat and extend tool life. The HSK coolant tube standard refers to the relevant specifications and requirements for coolant tubes suitable for HSK threaded interface tool holders. HSK coolant tubes are usually used to provide cooling and lubrication for cutting tools during machine tool processing. This article will detail the standards and functions of HSK coolant tubes.
Material of the Coolant Tubes: Common materials for ducts include stainless steel, high-speed steel, and hard alloys. The choice of material should meet the requirements for the duct's strength, wear resistance, and corrosion resistance.
Size of the Coolant Tube: The size of the coolant tube should meet the specifications of the HSK threaded tool holder interface to ensure a close and stable connection with the tool holder.
Layout of the Coolant Tube: The layout of the coolant tube should be reasonable to maximize the cooling and lubrication effect of the coolant on the cutting tool. The duct should cover the entire cutting area of the tool and avoid coolant leakage or blockage.
Connection of the Coolant Tube: The connection part of the coolant tube and the tool holder should have good sealing performance to prevent coolant leakage. Common connection methods include threaded connections and welded connections.
Positioning of the Coolant Tube: The position of the coolant tube within the tool holder should be accurate and stable and should be able to adapt to different cutting conditions. The positioning of the duct should avoid friction or collision with other components and ensure smooth coolant flow through the duct.
The primary function of HSK coolant tubes is to reduce the thermal expansion of the HSK tool holder during the machining process. During high-speed cutting, dry cutting, and other processes, a large amount of cutting heat is generated due to the deformation of the cutting material and the relative movement between the tool and the workpiece. The HSK coolant tube introduces coolant into the interior of the tool holder, allowing it to quickly transfer heat during machining, thereby reducing the thermal expansion phenomenon of the tool holder and maintaining the normal working state of the tool.
In summary, the HSK coolant tube standard ensures that the duct meets certain quality guarantees in terms of connection, layout, and water delivery in HSK threaded interface tool holders in order to improve the lifespan and processing efficiency of cutting tools.
