Efficient Oil Mist Filtration for CNC Lathe Operations

logo-torch
Client
The client specializes in operating CNC lathe equipment for precision machining of metal components.
Project Feature
The client operates CNC lathe equipment primarily used for precision machining of metal components. The process involves high-speed cutting, drilling, and shaping of various metals, resulting in the generation of oil mist and metal particulates.
Production Process
The primary concern is the accumulation of oil mist in the air within the working chamber dimensions of 1800x1000x850 mm. This not only poses health risks to workers due to inhalation but also contributes to slippery floors and potential damage to machine integrity and performance. Effective air filtration is required to manage these contaminants and maintain a safe and efficient working environment.
Problem
The current air filtration setup is insufficient for the volume and nature of contaminants produced by the client’s operations. It consists of an outdated filtration unit that struggles to maintain optimal air quality, leading to frequent maintenance issues and inefficiencies.
Temperature
The operating environment typically maintains a temperature range of 18-24°C (64-75°F), which is standard for such machining processes.
Gas/Dust
The main contaminants are oil mists generated from the lubricants used during the machining process, accompanied by fine metal particulates. These contaminants can vary in concentration depending on the materials being processed and the specific operations being performed at any given time.
