Introduction

In the machining industry, wet and micro-lubrication processes are becoming increasingly important. For wet machining, a large amount of cutting fluid is required continuously and stably.

The cutting fluid is delivered to the machining area via a high-efficiency flow section of the media transport unit, ensuring that it arrives quickly with sufficient flow and pressure to meet the requirements.

The system addresses the needs for cooling, lubrication, and chip removal; the "precision control" section can precisely adjust the delivery volume and timing of the cutting fluid according to changes in machining conditions.

This machine avoids resource waste. For micro-lubrication machining, only a very small amount of lubricating oil mist needs to be precisely sprayed onto the cutting point; the "precision control" part can...

Precise control of the amount, direction, and frequency of oil mist generation ensures lubrication while reducing oil consumption; the "high-efficiency circulation" section further assists...

The high-speed, lossless delivery of oil mist ensures accurate application to the processing area even in high-speed machining environments, significantly improving processing quality and performance.

efficiency.

Hollow tool shanks (HSK) and pyramidal tool shanks (PSC) are widely used in the market. The International Organization for Standardization (ISO) established this standard in 2021.

Standards for media transmission units with these two interfaces were released in 2016 and 2022.GB/T 46624, "Media Transmission Units for Tool Interfaces," is proposed to be...
