When was the last time you thought about deep cleaning your power tools? With the exception of cleaning off excess dirt and grime, it’s probably not something you consider regularly.

Prevent the Spread of COVID-19 with Metabo’s Tips on Cleaning Power Tools

When was the last time you thought about deep cleaning your power tools? With the exception of cleaning off excess dirt and grime, it’s probably not something you consider regularly. But with the recent spread of SARS-CoV-2 (COVID-19), it may be time to rethink your tool maintenance plan.

You’re familiar with the reasons why regular maintenance is important for the life and effectiveness of your tools. You know that consistent tool maintenance helps you prevent:

  • Rust build up
  • Dust that can clog moving parts
  • Loose or missing bolts, knobs or gauges
  • Dull cutting edges
  • Poor alignment

But did you know that good tool hygiene can prevent the spread of coronavirus in your workplace?

What We Know About How COVID-19 Spreads in the Workplace

We’re learning something new about the novel coronavirus every day, but current research shows that the virus spreads via respiratory droplets through person-to-person transmission. That’s why it’s recommended that workers remain at least 6 feet away from one another, wear masks when they cannot socially distance and try not to share tools, equipment or other materials that could have COVID-19 on the surface.

Workers can minimize the risk of contracting and spreading coronavirus to one another through frequent handwashing and sanitizing of work stations and equipment. To learn more about preparing your facility against the virus, read COVID-19 Preparedness Tips: Does your facility pass the test?

Prevent the Spread of COVID-19 with Metabo’s Tips on Power Tool Cleaning

Sometimes it’s not feasible for every employee to have their own set of power tools. In this case, it’s important that power tools are appropriately cleaned and disinfected to prevent the spread of the virus in the workplace.

If your tool, battery or charger needs to be cleaned, there’s a right way and wrong way to get the job done without causing damage to the tool or injury to the operator. Our partners at Metabo created a handy guide on the best way to clean power tools. View the entire guide here.

Both the Center for Disease Control (CDC) and Metabo recommend tools be cleaned according to the operator’s manual and left to rest for 72 hours. This is because the virus is thought to live on plastic surfaces for as long as 72 hours. If you are unable to let it sit for that long, you can consider cleaning with a sponge or cloth dampened with a diluted bleach solution and allowing to air dry. Just remember you can only use the solution to clean a power tool or charger, but never a battery.

Metabo recommends mixing 5 tablespoons of bleach per one gallon of water or 4 teaspoons of bleach per one quart. When cleaning the tool, be careful to not allow liquids to flow into the tool. Avoid contact with any electrical terminals or power cords.

Important Things to Remember When Cleaning Your Power Tools

  • Always unplug and remove batteries before cleaning
  • Check manufacturer’s instructions for proper care and maintenance
  • Treat your battery maintenance differently than power tools and chargers
  • Don’t use bleach to clean batteries
  • Don’t use tool or charger if you spot any form of degradation
  • Never mix bleach solution with ammonia

At M&M Sales & Equipment, it’s our mission to help our customers work safer and more productively, especially during these difficult times. If you have questions on how you can protect your workers and your shop while improving operations, please call one of our four Texas locations.

How Regular Machine Coolant Sump Cleaning Leads to Better Metal Cutting Performance

How Regular Machine Coolant Sump Cleaning Leads to Better Metal Cutting Performance

Sumps are the underappreciated workhorse of your machining operations and play a major role in metal fabrication. Sumps hold the liquid that keep cutting inserts and workpieces cool in the metal cutting process. Sumps also collect oil and gunk so letting it just sit there can gum up machinery, causing major damage to machines and their performance.

Any time a sump isn’t in use, even for a short period of time, the coolant begins to break down. Have you ever come into work after a long weekend and been met with a terrible smell? That smell is likely your cutting fluid breaking down. Tiny microorganisms are chomping on tramp oil that has leaked into your coolant. The result is not only a horrible odor, but also the potential for degradation of your cutting tool’s performance. Regular sump cleaning and maintenance helps you eliminate things that could be lurking in your sump, including:

  • Chips
  • Swarf
  • Mold
  • Fungus
  • Bacteria
  • Tramp oils

If you’ve had to shut down operations for any period of time, even over the course of a weekend, and haven’t performed regular sump coolant maintenance, you could be looking at serious and costly problems.

3 Reasons to Keep Your Machining Coolant Clean and Free of Sludge

Operators that perform regular sump cleaning and coolant recharging experience benefits such as better machine performance, fewer machine breakdowns and less downtime. Here are just a few ways that your metalworking fluid can impact your shop’s performance.

  1. Better Tool Life
    Regular coolant changeouts and maintenance allow your machines’ tooling to perform better. Fresh coolant offers better lubricity when cutting a variety of materials, from soft metals to very hard and brittle variations.
  2. Better Machine Performance
    Old or dirty coolant can leave residue on the machine causing components, plates and tool holders to become sticky. Gummed up parts can lead to slower production, tools falling out of place and breakage of inserts and drill bits.
  3. Less Wear and Tear on Machines
    Using poor quality coolants can cause rust to form on chucks, vises, ball screws and other machine surfaces. Over time, this corrosion can cause premature machine failure and unnecessary replacement costs. Additionally, the wrong fluid can cause excess foam which may diminish the fluid’s ability to carry heat away from the tool, further limiting tool life.

If you’re looking to get the most out of your machine tool investment, Master Fluid Solutions has the general use and specialized formulas you need for improved sump life, repeatability, reliability and increased profitability. Contact your M&M Sales & Equipment representative to learn what coolant is right for your applications.

10 Steps to Sump Coolant Changeout and Tips for Longer Sump Life

Part of any good coolant maintenance program is regular evaluation of the coolant and laboratory testing performed either internally or through the coolant manufacturer. Depending on the size of your operation and the systems in use, this can be a cost many don’t expect- especially in cases of smaller coolant systems. Compared to larger coolant systems that may have the capacity to hold thousands of gallons of coolant, smaller coolant systems can be more expensive to maintain and have less filtering capabilities. On the other hand, failing to perform regular maintenance can quickly lead to poor machine performance and system breakdown, costing you thousands in unplanned downtime, repairs and lost jobs.

Below you’ll find recommendations on steps you can take to ensure optimum sump health and coolant life.

  1. Completely drain sump of all fluids
  2. Remove any material, chips, sludge or gunk from your sump
  3. Add water to circulate throughout the entire system, filters and lines
  4. Add the recommended amount of machine coolant sump cleaner
  5. Circulate for several hours, longer if sump hasn’t been cleaned in a while
  6. Manual scrubbing or steam cleaning may be necessary to remove stubborn or hard to reach residue
  7. Drain the entire system free of all fluids
  8. Flush completely with fresh water, making sure to thoroughly circulate water throughout
  9. Add water and recommended amounts of coolant
  10. Circulate coolant throughout the entire system and be sure to reach normal operating temperatures

Pro Tip: Never use common cleaners like bleach or floor and surface cleaners when cleaning out your sump. Choose a sump cleaner specially designed to disinfect, inhibit corrosion and control foam. When in doubt, talk to your M&M Sales & Equipment representative or review your manufacturer’s manual for recommended cleaning instructions.

It’s no secret that the effects of the COVID-19 pandemic have been widespread, affecting everything: manufacturing production and machining orders, lead times and sales, even the very process of doing business.

How Machine Shops in Texas Use Innovation to Adapt Operations in the Time of COVID-19

It’s no secret that the effects of the COVID-19 pandemic have been widespread, affecting everything: manufacturing production and machining orders, lead times and sales, even the very process of doing business.

Today, the availability of increased virus and antibody testing is moving many states to kickstart their phased reopening plans. As the world of manufacturing begins the difficult task of getting back to “normal,” smaller machine shops in Texas are employing safeguards like social distancing to help curtail risk and mitigate further disruptions to operations.

Businesses are implementing health and safety practices that include:

  • Restriction of interactions between employees
  • Alternating shifts, with some companies placing a minimum of one hour between shifts to prevent overlap
  • Performing temperature checks
  • Providing hand sanitizer and antibacterial soaps
  • Implementing regular cleaning and sanitizing procedures on high touch surfaces
  • Installing high-efficiency air filters
  • Recommending stringent personal hygiene
  • Continuing to allow non-essential personnel the opportunity to work from home
  • Providing personal protective equipment
  • Offering zero contact ordering and delivery options

Related: COVID-19 Preparedness Tips: Does your facility pass the test?

COVID-19: Innovation in Times of Crisis

The world of manufacturing is no stranger to innovating creative ways to solve problems. So, it should be no surprise that the challenges of the coronavirus paired with manufacturing ingenuity have led to advanced technologies and solutions for combating the virus.

These innovations have emerged to help industries of all kinds operate safely and in accordance with regulatory guidelines. Not only have many organizations switched gears to produce much needed equipment like respirators and face shields, but they are also using them to get back to business.

Here’s how machines shops can adapt to the many challenges of operating within the “new normal”:

Protective Shields have been designed to protect employees and guests from the spread of germs, especially in companies that conduct customer-facing activity. Meant to reduce the transmission of the virus, these shields can be used in a variety of ways and include freestanding and countertop options.

Temperature Check-In Stations have been developed that solve the need for regular temperature checks, as well as the required documentation of testing. Temperature stations can be configured to track employee check-ins and sound alarms when those who are above the temperature threshold or unauthorized personnel attempt to enter the facility.

No Contact Payment is a relatively new technology that combines computer vision and artificial intelligence. This enables retailers to bill customers as they leave the store. Additionally, many companies are employing curbside delivery options to reduce risk of exposure to both customers and staff.

In the midst of this crisis, company leaders have an opportunity to shape and mold their company’s culture. How employers react to a crisis can have a serious impact on not only your employees’ health and safety, but also their trust in the company.

Unfortunately, there is no roadmap on how to thrive during a pandemic, but we can offer a few examples on how businesses can build a stronger and more resilient team.

3 Ways to Help Employees Manage Coronavirus Stress

Mental health is as important as physical health for employees today. Here’s how managers are helping their teams:

  1. Maintain clear and honest communication
    Throughout the coronavirus pandemic, uncertainty has been the only constant — leaving many employees unsure about their future. Be sure to communicate company plans and encourage open discussions to help minimize miscommunication or rumors. Provide frontline supervisors with the information and data they need to answer commonly asked questions, both accurately and honestly.

  2. Focus on the needs of your staff
    It’s important to remember that everyone is struggling with various degrees of stress due to the coronavirus. Not only will employees need access to PPE, safety equipment and cleaning supplies, they may require additional flexibility in their schedules due to closed schools, limited childcare or other family responsibilities. Look into support programs that can alleviate the personal stressors faced by your team and offer leave packages, if possible.

  3. Boost morale and build goodwill
    What services could your company offer your local community? Talk to employees to uncover the most pressing needs of their communities and then work to get involved. Not only will local towns benefit from this action, but helping others builds morale and puts things into perspective, reminding us that tough times will not last forever.

M&M Sales & Equipment is here to help your business succeed with advice and suggestions on how you can improve operations, enhance worker satisfaction and increase your profitability. From cutting tools, abrasives and cutting fluid to safety and MRO supplies, we are your full-line distributor.

7 Tips for Choosing the Right End Mill for the Job

M&M Sales and Equipment is a cutting tool specialist, offering end mills and other cutting tools and accessories from Sandvik, Guhring, Drillco and other leading brands in West Texas, including Odessa, Lubbock, Amarillo and Ft. Worth. Here’s a guide on end mills, and how to choose the right ones for the job:

It’s no secret that machinists tend to speak their own language — even in something as simple as basic math. The rest of the world starts counting at the number 1. But ask a machinist to explain how they measure, and they’ll tell you that it all begins at one-thousandth of an inch (0.001”).

When we talk about cutting tools, it’s very much the same thing. Machining terminology is not the same to a layman. To the outside world, the terms drill bit and end mill are often used interchangeably, but that can create confusion when referring to the specific tooling required in CNC machines. Industrial CNC (Computer Numeric Control) machines use rotational cutting tools called end mills to remove material.

What are end mills and how do they differ from drill bits? Drill bits plunge vertically into material to create holes while end mills typically cut horizontally and laterally, but most mills can actually cut vertically as well.

Here’s a good visual that shows the difference between a regular drill bit and an end mill:

Choosing the Right End Mill for Your Job

End mills are designed with purpose and each tip shape offers a unique clearing path for various applications. Deciphering what end mill to choose is largely based on the project, what kind of material needs to be cut and the desired surface finish. Choosing the wrong cutting tool can quickly damage a work piece, causing you to scrap an entire batch. Not only is that a huge waste of time, but also a significant cost to your organization.

Related post: 5 Ways to Reduce Scrap in Your Metal Cutting Operations

There’s a lot to consider when choosing the right end mill for your CNC operation. We’ve pared down a few important tips from Machining News to help you select the right end mill:

  1. End Mill Length
    First, decide the depth your end mill must cut. Choose the shortest length end mill that can still make the cut. The reason? Choosing the shortest length greatly increases the stability of the tool. This will allow for more aggressive feeds and speeds, while reducing the tendency for the tool to chatter.

  2. End Mill Materials
    Two of the most common materials used in the manufacturing of end mills are high speed steel (HSS) and carbide. HSS is useful in older, slower, or less rigid machines as well as one off or very short run production. It will run slower, but is less expensive, less brittle and more forgiving of unstable conditions. Carbide is preferred in CNC machine tools where higher speeds, fewer tooling changes and increased productivity are required. In these applications, the higher cost is easily justified by longer tool life and shorter cycle times.

  3. Flute Count
    Flutes are the helical grooves that wrap around the sides of an end mill. A smaller number of flutes (2-3 flute tools) will offer more flute space for long chipping materials such as aluminum.   A larger number of flutes reduces the flute space, but can offer increased productivity in shorter chipping materials such as medium to high carbon steel and iron. For steel, stainless steel, high temp alloys and iron, a four flute endmill is preferred for slotting applications and can be a great general-purpose tool. Higher flute counts should be reserved for applications with a low radial depth of cut to allow for chip evacuation.

    Note: Proper chip evacuation is important because re-cutting chips will lead to significantly reduced tool life

  4. End Geometry
    Choosing the right end mill geometry is critical to the tool’s success. Paying close attention to the materials that the manufacturer recommends for a given tool can help to ensure your success. Of equal importance are the speeds and feeds the manufacturer recommends for that material.

     
  5. End Mill Coatings
    Coatings are helpful in reducing friction and protecting the carbide from the heat that is generated in cutting. Some coatings are more suitable for certain materials. Once again, paying attention to the manufacturer’s recommendations is the easiest way to make sure you are using the correct coating.

  6. Tool Life
    Cheaper isn’t better. If you have high production and heavy workloads, it’s critical to invest in the right tooling that can keep up with the volume of work. Choosing inexpensive or inadequate tooling costs time and money on wasted material, scrap, wasted tool spend and added wear and tear on your CNC machines.
