Spindle for AYP Applications

High speed spindles for AYP are used in a wide variety of applications. High speed cutting is used to improve quality, reduce cycle time, and increase manufacturing efficiency. Simply put, rotating a cutter faster will permit the cutter to perform the work faster, as long as the maximum operating limits of the cutter are not exceeded.

Any application requiring the use of a small diameter cutter can benefit from using high speed technology. Whether the need is for micro-drilling or micro-milling on a Swiss style CNC lathe, engraving on a machining center, or mold & die finishing with a small diameter ball-nose end mill, running a small cutter at higher RPM will generally save time and improve your process.

In soft materials, there are few limits to cutter speed, however, higher RPM usually requires higher spindle for AYP power. For example, machining aircraft aluminum components can benefit when using high speed cutting technology, including superior surface finish and thin walls, as long as the spindle for AYP motor has sufficient rigidity and power to support the resulting high material removal rates.

In mold and die applications, the cutter speed will be limited based on the cutter material and coatings. So, high speed is typically used for semi-finishing and finishing operations, with a very small contact area during cutting. This process results in an exceptional surface finish that minimizes or eliminates hand finishing, saving time, cost, and optimizing final part accuracy.

One very popular high speed application is micro-drilling, often required for medical and electronic component parts. A standard machine tool cannot perform this operation in a reasonable time, and often struggles to maintain acceptable quality. A high speed spindle for AYP, with exceptional accuracy (less than 1 micron runout), can perform this operation at a fraction of the time and maintain the highest quality, while also extending tool life.

To apply high speed technology to your manufacturing operation, it is critical to work with a partner that has the proven knowledge and experience to successfully advise and direct your efforts.

By working closely with machine tool OEM’s, distributors and end users, we have worked on hundreds of high speed cutting applications, including spindle for AYP selection, feeds & speeds, ROI, and work holding requirements.

Line diameters of Trimmer Line

Before I discuss the actual trimmer lines, I’ll give an overview of what size diameter you’ll need.

Generally speaking there are three size groups of diameters which are:

  • Small weeds (between .60 – .80 inches)
  • Medium weeds (between .08 – 0.110 inches)
  • Large weeds (anything over .115+ inches)

Smaller to medium size weeds you’ll be fine using a line that has the diameter size of .60 – .80 inches. This will be for your smaller jobs around the house, your front lawn and whacking the weeds from your driveway and small residential areas.

Medium size weeds you’d want to opt for a line around 0.80 – 0.110 inches in diameter. This sizing is ideal for your bigger gardens where you have slightly bigger weeds, this size of line commercial areas too.

Dealing with large weeds you’ll want anything from .115+ inches and bigger. Places of work that need a large amount of trimming, such as large estates, huge gardens, and industrial areas of landscaping, this should be your weapon of choice.

Pro tip – Before you go and buy a string trimmer line, check your string trimmer to see what it is capable of holding, as most can only go handle a certain size. Refer to the product handbook if you’re unsure.

In fact there are several types of best lawn mower blades including reel, deck, mulching blades and lifting blades. Let’s consider all of them in details.

Reel Blades

Reels devices are specific for reel lawn mowers. They consist of 3 and up to 7 helical blades, which are welded in a horizontally rotating cylindrical coil, creating a shearing cutting action. Unlike other types of the best lawn mower blades, these ones can’t be replaced, so you will need to choose a new grass cutter. If the situation with you tool is not critical, take care of the blades by means of clearing and sharpening them.

Deck Blades

Deck blades is another name for straight mower blades. They are used only for rotary cutters.

Mulching Blades

Mulching knife is represented by a curved surface and operates in 3 ways: lifting, mowing, and mulching. It allows chopping a high grass into the smallest pieces.

Lifting Blades

Devices of this type have a special upward angle used for airflow improvements. The best high lift mower blades help to cut a lot of grass within a short period of time.

What is an air filter?

Air filters are cleaning devices that capture unwanted, sometimes harmful pollutants from the air circulating in your home.

They are essential components of forced-air HVAC (heating, ventalation and air conditioning) systems. With indoor air pollution as one of the top five environmental health risks, it is important that homes have adequate ventilation and clean air to help control or eliminate the potentially harmful elements.

In addition, air filters should be routinely monitored and changed to maximize comfort for those indoors.

Trimmer Line Styles

Round Trimmer Line

Do you use your trimmer to trim grass edges or get rid of weeds around a residential yard? Does your yard contain a minimum amount of weeds that don’t require a lot of time to cut?

Round Trimmer line is the standard, basic shape that won’t wear down as quickly as other trimmer lines. These trimmer lines are used for lighter, residential use with minimum weeds. Round trimmer line breaks less and is more durable against concrete, trees and etc. to give you an extended use time. This is also the easiest trimmer line to replace in your trimmer.

Multi-sided Trimmer Line

Do you have a larger yard, thicker weeds, or do you use your trimmer for commercial use? Multi-sided trimmer lines are best used for medium sized jobs with heavier weeds or larger lawns.

Multi-sided trimmer lines have multiple sides that produce a cleaner cut. These lines commonly come in the shape of a star, square or pentagon. These trimmer lines slice through heavy weeds and thick grass quickly and efficiently, giving you an even cut in less time. However, multi-sided trimmer lines break easy when they come in contact with stones, fences, curbs, sidewalks and etc.

Serrated Trimmer line

Do you have a lot of weeds on your property? Or do you use your trimmer for a lot of commercial use? Serrated trimmer lines are used for heavier jobs with thicker weeds and more area to cover.

With edges that act like teeth or a kitchen knife, this serrated line can quickly saw through grass blades and thick leaves, leaving a cleaner trim. This trimmer line has extra cutting power and can be used for medium-heavy jobs. A serrated trimmer line can cut through weeds easily and quickly to keep your trimming time at a minimum.

Twisted Trimmer Line

Do you have a lot of heavy, thick weeds? Do you use your trimmer for rugged commercial use? A twisted trimmer line is used for heavy-duty use and on yards with a lot of heavy, thick weeds.

This line is a step up from the round style line and offers durability when hitting concrete or hard surfaces. This trimmer line can reduce trimmer vibrations and noise levels while giving you a clean, even cut.

The physics of a front wheel driver lawn mower

This is a diagram right at the instant that the mower starts moving. This means that the friction force accelerates the mower for just a little bit. The key is that more friction means better. There are two things that must be true for these other forces. First, the vertical forces have to add up to zero Newtons otherwise it would accelerate in the up or down. Second, the sum of the torques about any point must also be zero. If not, the mower would have a rotational acceleration instead of staying level.

The torque is the important thing to consider here. If you look at torques about the center of mass, the force from the person would create a clockwise torque. There has to be some counterclockwise torque in order for the total torque to be zero. This means that the force from the ground on the lawn mower front wheel has to be greater than the back wheel. That’s not good. The harder you push on the mower (horizontally), the more the front wheels “dig in” the ground without providing any traction.

Now imagine the mower had lawn mower front wheel drive like the Craftsman. In this case when you push harder on the mower, you get MORE traction. Remember, more traction equals more better. Plus, there is another benefit of lawn mower front wheel drive. When you want to turn the mower, you push down on the handle and lift the lawn mower front wheels off the ground. Now it doesn’t matter if they are turning or not because they are off the ground.

Air Filters – Made to Protect and Perform

Air filters used in off-road applications; heavy-duty construction, mining and ag equipment, plus compressors and generator sets.


Air filters were tested head-to-head against OEM filters. They were bombarded with dust, vibrated and shaken – and then carefully examined. When tested per ISO 5011, air filters perform well on the important characteristics of dust capture – where they reached a 99.97% overall efficiency – and capacity (filter life). It’s when we compare sealing technology that air filters really stand out.

Air filters with RadialSeal technology deliver two critical sealing advantages compared to the OEM filter:

  • 50% more sealing area
  • Up to 2 times more gasket compression around the frame for a sure-fit seal

Compare this to a thin O-ring design that offers less sealing area and less compression – and it’s easy to see why more sealing area and more compression is better for protecting engines.

How to Replace Round Trimmer Line?

A string trimmer is a great way to maintain and care for your lawn. And luckily, most models require very little maintenance. But whether you own an electric trimmer or gas-powered trimmer, the one task you’ll certainly have to do is replace the trimmer’s line. Thankfully, this is an incredibly easy project that you can accomplish in just a few minutes. Besides replacing your round trimmer line whenever the spool is depleted, you should also replace it at the beginning of each season since your old line can turn brittle over the winter and will break easily.

Brittle line will also wear down faster than fresh line when you use it on thick weeds or harder surfaces. Most models are built with a dual-line design and are fed by bumping the head. Even if your model uses an automatic feed, most of the steps will be fairly similar, though you should consult with your owner’s manual in order to make note of any different steps involved.

How to Restring Dual-Sided Spool?

To replace the round trimmer line on a conventional bump head model, you need to disassemble the round, black cutting head of your tool. The first thing you need to do is prep your new string round trimmer line by cutting 10 feet of replacement line. You can choose to use a twin-strand split line or even cut two pieces of round trimmer line to 10′ each. Now, you want to disassemble the cutting head of your trimmer by unscrewing the bump knob and taking the inner wheel and spring out from the housing.

To install the new line, look for the two holes located at the top of your inner reel. Choose one of these holes and place both ends of the line into it. Then just pull the line completely through until only 2 to 3 inches remain. Next, you want to loop the short ends of the round trimmer line through the second hole and close the loop by pulling the long end. Wind the new line around the wheel in the direction indicated by the arrow on top of the wheel, making sure that you keep it taut so that your line is wrapped evenly.

Once you only have around 6″ left, simply push each string into the holding slots. With your line in place, simply reattach the spring to the tool’s shaft and feed the line through the spring head’s eyelets. Put the reel back into the shaft and align the eyelets on the spring head with the holding slots. Press the spring down and securely tighten the bump knob onto the trimmer head. Now, just pull the lines gently to ensure that they release from the holding slots. If the line comes out smoothly, your tool is properly loaded and ready to work.
