Summer Shutdown Time! Clean Machines Mean Smart Savings!

Summer shutdown is the perfect time to prioritise cleaning in your workshop and you may be wondering how it can save you money. This article will explore the benefits of maintaining clean machines and explain the machine cleaning procedure with our simple step-by-step guide.  

Why Clean Machines Save You Money

Longer Sump Life = Reduced Disposal Costs

Properly cleaning your machine tool ensures a longer sump life for your metalworking fluids. This, in turn, reduces the frequency of fluid disposal, resulting in cost savings for your business. When the sump is full of swarf, there is less fluid available, leading to harder to maintain concentrations, which ultimately results in more frequent topping up and dilutes the product's overall performance. Modern water-based metalworking fluids have improved biostability, but regular cleaning remains essential for optimizing fluid performance.

Reduced Labor = Saved Money

Cleaning your machines regularly reduces the need for extensive manual labor. Metal swarf in the sump create an ideal breeding ground for bacteria, which can degrade the fluid and negatively impact performance. Cleaning out the swarf and maintaining a clean machine minimises the need for manual intervention, saving time and money.

Increased Uptime for Your Machine Tool:

When your machine tool is clean and free from debris, it experiences increased uptime. Swarf and residues take up valuable space in the sump, straining pumps and hindering the fluid's cooling and wetting properties. By cleaning the machine and removing the swarf, you improve your metalworking fluids' performance, resulting in enhanced productivity and reduced downtime.

How to clean and recharge your machine sump

A properly cleaned machine tool will reduce your overall fluid costs. The frequency depends on several factors including visual inspection and monitoring results. In the past, fluids were typically only changed when they created an odor in the plant. Modern day water-based metalworking fluids have made remarkable strides in improving their bio stability. Despite longer sump life, cleaning machines to optimize your fluid's performance is essential.

How does this effect performance?

Swarf in the sump creates an ideal breeding ground for bacteria. Increased levels of bacteria will break down the emulsion, lowering the pH of the fluid, and therefore reducing the overall performance.

Swarf in the sump takes up valuable space that the metalworking fluid should occupy. Reduced sump levels due to the buildup of swarf place additional strain on pumps and the ability of the fluid to provide essential cooling and wetting properties.

Swarf can contribute to tool life, surface finish issues and skin irritation. Cleaning out the swarf from the tank dramatically improves the performance of metalworking fluids. Removing swarf and cleaning dirty surface areas on machine tools will provide extended sump life.

Using a high-quality machine cleaner such as our recommended ArrowClean 25020 shortens the cleaning process and removes insoluble soap residues and residue and build-up in the coolant lines of the machine tool.

To properly manage your coolant, your cleanout should include running a cleaner throughout the machine, dislodging sludge and removing biological residues. The cleaning process is an essential first step in coolant management, ensuring that your coolant has a fair chance of giving maximum performance with minimal problems.

 

 

Equipment and procedures

 Decide how often you need to clean your system. Discuss this with your fluid supplier.

  • If possible, prevent skin contact. If you cannot prevent skin contact, can you limit it?
  • Provide equipment to remove and replace sump fluids with minimum spillage, e.g., wet vacuum. Ensure the sump is cleaned before adding fresh metalworking fluid.
  • Avoid the use of high-pressure water hoses for sump cleaning where practicable.
  • Keep absorbent material to hand in case of spills.
  • Wear personal protective equipment, suitable gloves, eye protection, overalls.

 

Clean out procedure with ArrowClean 25020

  1. Add 3-5% of ArrowClean 25020 to the existing metalworking fluid.
  2. Circulate 24 hours in the machine tool.
  3. Clean all outside surfaces of the machine tool to remove residue.
  4. Stop circulation of machine tool, remove all fluid along with swarf and swarf from the sump. Clean surrounding area along with pumps, screens and filters.
  5. Properly dispose of fluid in accordance with local regulations.
  6. Refill with a weak mix 2% to avoid corrosion. Flush system and rinse sump area.
  7. Empty flushed coolant.
  8. Properly dispose of fluid in accordance with local regulations.
  9. Recharge your machine tool with ArrowCool product, ensuring the fluid is mixed properly and at the proper concentration.

Caution:

  • Do not remove swarf and fines from the sump by hand. Use suitable tools, e.g., brushes and shovels, and wear suitable cut-resistant protective gloves to prevent injury.
  • Cleaning a large, enclosed sump or underfloor tank may create a confined space risk. Ensure you have assessed the risk and put in place measures such as a permit to work system.

 

Developing and sticking to a proper preventative maintenance program will result in lower fluid costs, enhanced tool life and improved operator acceptance.
