5 Tips to Enforce World-Class Lockout/Tagout Safety Procedures for Your Grinding Machine

Federal OSHA lockout regulations prevent unauthorized operation of a grinding machine when in an “unsafe” condition, such as during service or maintenance when the true state of the machine may be unknown.  Federal regulations further require a machine technician to lockout all points of hazardous energy, such as the electrical system, the hydraulic system, the pneumatic system or any other danger-prone machine attribute, should the technician step away from the machine. Additionally, the technician is the only person who may remove the lock.

GCH Global Service honors any lockouts that have been applied to machinery.  Our service technicians, located worldwide, apply lockouts of their own, per OSHA or local practices, whenever a hazardous condition might be present.  The locks are not removed until service is fully completed and the machine has been checked for safety.  If your machine requires service or if you need technical advice, contact GCH Global Service.

This month’s blog is provided by guest author Lindsey Walker, marketing manager for NEXGEN Asset Management in Sacramento, CA.

Employers invest a lot of time, effort and resources in developing and implementing efficient and effective workplace safety programs. Despite their efforts, every year workers suffer serious injuries and lose their lives in accidents. Below are the five best lockout/tagout practices that every employer should adopt to improve worker safety, maintain uptime and boost productivity.

Too Many Gears? GCH Offers Gear-Free Servo Drive Transmission

New Grinder Upgrade Can Increase Roundness By 30%

As the expert source for support and advice on centerless grinding equipment and grinding applications, it’s no wonder that GCH Tool sought to offer customers a replacement for old, unreliable mechanical gear transmissions, traditionally regarded as the weakest link in a centerless grinder.  Ever-increasing tolerances further demanded that GCH Tool develop a solution for its clients who could no longer depend upon this important-but-temperamental component to function properly. 

The Solution:  A Servo Drive Transmission

GCH Tool Group’s patented servo drive transmission is a cost-effective, noiseless and virtually maintenance-free transmission designed for installation in older centerless grinders.  Engineered to fit Cincinnati 200, 300 and 400 grinders without any machine modifications, conversion can be completed by in-house maintenance personnel or GCH Tool technicians.  The transmission provides the operator precise control of the regulating wheel -- a critical element to efficient and fast setup and consistent part production.

Grinder Spindle Repair Saves Time and Money

With a lifespan of up to 10 years or more, spindles are frequently out of mind, if not out of sight, in most shops.

And it’s not until those telltale signs of serious wear – an increase in scrap parts, a decrease in part quality, vibrations that can be seen or heard – appear that grinder spindles suddenly become top of mind.

At that point, the question becomes “Do I buy a new spindle or repair the one I have?”

The answer 99% of the time will be: repair the spindle.

The Six Fundamentals of Centerless Grinding

Centerless grinders are everywhere these days. You can find them in shops that specialize in centerless grinding, outfits that combine centerless grinding and machining and even factories that incorporate a centerless grinder into a broader manufacturing process.

It can seem like everyone has at least one, but how many shop owners and machine operators really understand their centerless grinders? Here are six fundamentals to help you educate yourself, your employees and coworkers about these incredibly useful machines:

Precisely Simple, Simply Precise

The design of centerless grinders is relatively simple: a stationary wheel and a rotating wheel hold the workpiece in place on a stationary work rest throughout the grinding process.

Make Your Work Blades Work for You

When it comes to centerless grinders, work blades can often be taken for granted. Spindle assemblies, accessories like filtration units or upgrades like servo infeed systems get a lot of attention, while the work blade is expected to just keep on working, grinding parts to the right size and shape.

But the proper selection of work blades, combined with appropriate use and care, will make sure these indispensable components function at optimal performance over the long haul.

There are three key factors in selecting the right blade:

·        Grinder model number

·        Diameter of the part being ground

·        The material the part is made of

How Often Should I Invest in Grinder Spindle Repair/Rebuild?

This month’s blog was written by Louise Petty, an online course author for High Speed Training, a UK-based eLearning company that offer a variety of health and safety training courses.

If your work involves the use of abrasive wheels then you’ll know how important it is to follow safe working practices at all times. A large part of this responsibility includes ensuring that your grinding wheels are kept well-maintained and in good repair so that they continue to remain safe to operate. If your wheel becomes worn down then it’s important that the disc is replaced with a new one – but how often should you repair or replace the grinder spindle that the wheel is mounted on?

Play Ball – and Know what to Look for in Your Next Grinder Parts Vendor

When you’re evaluating suppliers for your grinder parts, take a tip from professional sports organizations and look at each company’s bench strength – it’s something you want from your favorite basketball, football and baseball team, and something that you want in your grinder parts and spindles provider.

Just like a sports team’s bench strength, corporate bench strength indicates the ability to go the distance and provide the services and products you need, now and in the future.

Unlike sports teams, a company can’t measure its strength in stats like RBIs, shooting percentages or pass completions. But there are some important factors that you can look for to help gauge a potential vendor’s bench strength.

7 Reasons Why Your Grinder Components Should Be Hand Scraped

Much like the watchmaker or typesetter, the skilled hand scraper is a rare find today. While great advances have been made in grinding component design, metallurgy and heat treating, hand scraping remains an art that cannot be duplicated mechanically. Still, most manufacturers have abandoned it, claiming that it requires too much time to learn and too much patience to practice.

Despite its rarity, hand scraping is the method of choice for the most-highly respected and trusted manufacturers of grinder components. Hand-scraped components offer old-world craftsmanship along with new-world accuracy, and these top-tier companies would find the machined alternative completely unacceptable in their manufacture of dressers, slides and spindle bearings. 

When evaluating the quality of a grinder component and assembly manufacturer, why should you ask whether hand scraping is the standard practice? Here are seven important reasons:

1. Consistency 

Hand scraping ensures that components are manufactured to exacting specifications.  The more precise the components, the better the operation of the machine and the more consistent the final part.
