Accumulators and Their Capacity

Piston accumulator is a kind of the fluid power component, and is the only one which can store the energy in hydraulic systems. The unique advantage of piston accumulators is energy storage in usually and used in emergency, it also has several functions, such as temperature compensation, leakage compensation, counter balance, shock absorption, transfer barrier, shock dampening and pulsation dampening.

 

Today even modern accumulators possess limited capacity although their parameters develop every day. Alkaline accumulators are most popular accumulators as power suppliers for portable devices. For the past 25 years the capacity of accumulators has increased 5 times (just compare: properties of electronic devices have improved in thousand times). Thus, the accumulator capacity is ultimate and limited by sizes of its case. New advanced technologies don’t increase the capacity considerably, moreover, newest scientific data does not expect significant increases in capacity among this energy sources in the nearest future.

 

Unfortunately, as long as accumulators are based on electrochemical processes, we will be limited by energy storage devices. We will have to use accumulators big in their sizes, heavy, flaky, unpredictable in operation, rather expensive and thus, with a rather short term of life. Moreover, attempts of increase in capacity, reduction of weight and sizes of accumulators have led to by-effects, such as: a shorter service life and an increased self-category, without mentioning higher working costs. The matter is that one of methods to increase the capacity of accumulators is the use of a thinner plate of a separator dividing the anode and the cathode and which collapses faster, a consequence of that is the increased self-discharge. It means that buying an accumulator with a maximum capacity, we obviously get an energy source designed for the minimum durability. Probably, some of you have ever noticed that many accumulators which were produced in the 80’s, 70’s and even in the 60’s are still in use, while those bought in the 90’s are already out of order.

 

Today developments of fuel elements (hydrogen, spirit, gas, etc.) are considered as the most perspective but they are still far from perfect and are inaccessible to ordinary consumers. Along with the improvement of energy products, modernization of power consumers takes place. Much less energy is consumed by modern electronic devices than by their predecessors. All these circumstances allow using advanced achievements of science and engineering in the field of electro-power supply for achievement of more essential results.

Which Material is Right for Batting Cage Nets?

Urethane treated nylon, polyethylene, polyester, and KVX200™ are common material used in batting cage nets. However, KVX200™ premium netting is a commercial polymer that is also used in bullet proof vests. This material is strong, lightweight, does not absorb water, and resists breakdown in direct sunlight. KVX200™ employs an integral UV inhibitor. This means that the UV inhibitor is one component that is already inside the polymeric blend that gets extruded into individual fibers. Those fibers are then twisted or braided into twine. Since the UV inhibitor is built right into KVX200™, the UV inhibitor doesn’t wear off, as it can with nylon. Since KVX200™ doesn’t absorb water as nylon can, it resists rotting better than nylon or other materials.

 

KVX200™

 

KVX200™ is more expensive than polyethylene, although it is less expensive than nylon. While KVX200™ may be stronger than polyethylene, it doesn’t have the break strength of Nylon. KVX200™ is priced between nylon and polyethylene netting. For outdoor use the performance is nearly on par with nylon. These cages may provide the best value for those concerned with both quality and price.

 

Nylon

 

If you have an indoor cage, and durability and break strength is more important than budget, nylon netting is right for you. Nylon has the strongest break strength, and is by far the most durable netting for indoor use. Nylon has excellent resistance to abrasion, and outstanding overall durability. However, nylon is expensive.

 

Because nylon netting can absorb water, many manufacturers treat the nylon with some sort of bonding agent by either dipping or spraying the twine. Although treating nylon with a bonding agent will dramatically reduce nylon’s tendency to soak up water, it doesn’t stop it entirely. Eventually, nylon will likely shrink and rot.

 

When compared with polyethylene netting, nylon is initially stronger than polyethylene, but deteriorates faster. Nylon loses between 15% and 20% of its strength each year depending on conditions. For year one, a #36 nylon will have a greater break strength than a #36 polyethylene, but depending upon weather conditions, by the end of the third year polyethylene may be as strong, and KVX200™ may be stronger.

 

Although nylon netting has a high initial break strength, if left outside that strength can deteriorate rapidly. Nylon absorbs water and loses strength in direct sunlight. For indoor applications, nylon is an excellent choice. If your netting will be exposed to adverse weather, consider polyethylene or KVX200™.

 

Polyethylene

 

Polyethylene batting cage net is inexpensive and does not deteriorate as quickly due to moisture. As the netting is exposed to moisture, polyethylene retains a higher percentage of its strength than nylon. Polyethylene does not absorb water, so the problem of rotting and shrinkage disappears.

 

Polyethylene netting has drawbacks as well. Most blends of polyethylene don’t hold up well to direct sunlight. Not all polyethylene cages incorporate UV inhibitors. Ours do. This works well for indoor application, but it may not be practical over extended periods of outdoor use, especially in warmer climates.

Transform Grinding into a CNC-Based Technology

In the ever-progressing world of manufacturing nothing stays the same. If you are not improving continuously you cannot stay in the game for long. This is true in all progressive mold shops that have embraced the latest in CNC technology and automation in almost all aspects of production. The exception is that row of grinders that could have time-warped from the middle of the last century.

Automation in other areas is shining a greater light on the lack of automation in grinding. Every attempt has been made to move as much out of the grinding department as possible. With great strides being made in wire EDM, high-speed machining, and hard turning and milling, the grinding department is being bankrupted, in many cases. Still, there is a need for grinding in mold shops. Every shop has a bank of grinders. There will be a row of manual grinders of the usual types and a cluster of automatics. The technology in these machines remains unchanged in its basic function and capability.

The purpose of this article is to set forth some steps that can be taken to change the grinding department into a CNC department, which is based on successes seen in a range of mold shops from small to large—but all having a need for precision grinding of mold components.

Automatic Surface Grinder Benefits

  • The operator can keep two machines running unattended.
  • Skill level is lower so most CNC operators can do these tasks.
  • Accuracy is provided by the machine.
  • Wheel management for faster, simpler setups.
  • Develop repeatable processes that are machine-based not operator-based.
  • Core requirements for the job are controlled—including wheel offset, auto-dress, simple dimensional inputs into conversations graphical screens, and grind.
  • Critical dimensions can be checked on the grinder automatically.

Six Steps to Grinding Transformation

The steps a mold shop can take to transform grinding into a CNC-based technology are:

  1. Strategically build around the correct machines.
  2. Must have a committed attitude from management.
  3. Must have a positive attitude for grinder hand to increase productivity through CNC technology.
  4. Plan to cross-train CNC operators to operate CNC surface grinders.
  5. Develop high competency at core grinding tasks like surface, slot, and step grinding.
  6. Think outside the box.

These simple tasks can be completed through the assistance of a high-precision CNC surface grinder faster and easier than through conventional manual grinding.

Basics of the Liquid Filling Machine

The preferred liquid filling machine in a factory is certain to depend on a variety of factors. It not only has to match the type of liquid and bottle, but should also complement the current budget and future growth. Here are a few things to help identify the right liquid filling machine:

 

Type of Liquids

 

A major consideration with the filling machine relates to the type of products that are being bottled. Liquids can be sticky, thick and semi-fluid in consistency, so it is essential to use a machine that matches. For instance, the thick liquid is best paired with the piston filling machine and the thin liquid goes well with the gravity filling machine. There are some liquids that can satisfactory use the same machine, but it generally benefits to always stick to the specific type of machinery to complement the product.

 

Unique Characteristics

 

There are plenty of liquids that can change consistency or thickness as the local temperature starts to change. Other liquids can feature particulates, such as liquid soaps and salad dressings. Any liquid with a unique characteristic can have an impact on the preferred type of filler. For the thick liquids like spaghetti sauce with pieces of mushrooms or vegetables included it is certain to benefit from a piston machine because it has the wide pathway. Using the wrong machine can soon lead to blockages, which means the problematic and slow filling process.

 

Type of Container or Bottle

 

The type of container or bottle is a further consideration in choosing the preferred piece of machinery. For instance, the clear bottle is often paired with the overflow filler to achieve the consistent fill levels. This gives the most attractive look when placed on the store shelves. Also, the size of the bottle will have an impact on the type of filler nozzle to use.

 

Bottles to Fill Per Hour

 

The level of automation varies with the different filling machines. The machine is built to be fully automated, semi-automatic or a tabletop. The fastest fill option is the automated machines that are significantly faster than the alternatives and require minimal operator interaction once the work is underway. The semi-automatic has a much slower production rate because it is necessary to manually switch on the filling process and clear the filled bottles as required. The preferred liquid filling machine should have the ability to meet the production demands for the size of a particular business.

For the amount of physical abuse that duck hunters take while out hunting it could be considered an extreme sport. Mud, wind, water and cold are usually experienced in spades on most occasions. Because of these extreme weather conditions it is important to keep yourself warm and comfortable. The most important piece of clothing when trying to stay comfortable and warm is a good pair of quality duck waders so why not get the best duck hunting waders you can?

 

Do I Need Chest Waders or Hip Waders?

First of all, if you will be hunting in all seasons I highly recommend that you purchase one of each. When I am hunting in cold weather or deeper water then I would definitely wear my chest waders to keep me warm and dry. If it is warm and sunny or I’m going to be hunting around shallow streams or creeks, then I would use my hip waders.

 

If I were to purchase just one pair of duck hunting waders I would choose a pair of chest waders. With a chest wader you can always drop the shoulder straps and tie them around your waist when the weather is too warm.

Factors You Must Consider When Purchasing a New VMC

In a typical production machine shop, the processing capabilities required can vary greatly between applications: some value power and torque over rpm, others value spindle speed more than torque or power. To ensure the highest level of productivity in all cases, all of these factors must be evaluated when considering a new investment in a vertical machining center.

 

With numerous different manufacturers of vertical machining centers (VMCs) on the market today, selecting the right VMC for a production environment can be a challenging and stressful endeavor. Each machine is designed and built differently, with unique features and characteristics. The key is determining how each impacts performance.

 

In order to cut through the clutter to find the right solution, manufacturers must first learn how to effectively evaluate machine performance by understanding key differentiating characteristics. Several factors to consider during evaluation are parasitic times, cutting times, thermal control, machine construction and production support features.

 

PARASITIC TIMES

Today the average non-cut, parasitic time of a typical production machine shop consumes approximately 30 percent of the machining process. Part designs continue to grow in complexity, with a higher volume and diversity of closely spaced three-dimensional features. In order to minimize parasitic time and optimize production capabilities, evaluation of axis motion and tool-change technologies are critical in the selection of a production VMC.

 

AXIS MOTION

There are substantial differences in the axis motions of modern VMCs, even when evaluating just the top tier of machine tool manufacturers. We conducted a recent comparison test to evaluate the differences in axis rapid traverse rates of several leading VMCs that demonstrated variations as high as 41 percent. A similar evaluation was given to axis acceleration and deceleration rates, resulting in a 45 percent difference between averaged rates. The Z-axis acceleration and deceleration rates in particular, which are crucial in drilling, pocket milling and tapping operations, resulted in performance variations as high as 75 percent.

 

TOOL-CHANGE TECHNOLOGIES

The second key factor equally as crucial to parasitic time is tool change. When considering a VMC, manufacturers should examine the full tool change time from the moment the spindle stops to leave the work zone to the point at which it returns to the desired position and speed. While spec comparisons between leading VMCs might indicate minimal differences in tool-to-tool time, a true comparison that includes chip-to-chip time reveals variations as high as 18.4 percent.

 

In essence, the differences in axis motion and tool-change performance of production VMCs can have a significant impact on a manufacturer’s profitability.

 

CUTTING TIMES

Alternative to parasitic time is the actual time a vertical machining center spends cutting. With parasitic time consuming 30 percent of the machining process, the remaining 70 percent of the machine process is spent in the cut. Cutting times are generally examined by spindle capability, in which there are three primary factors to evaluate: power, torque and speed.

 

To ensure the highest level of productivity in all applications, manufacturers considering new investments in VMCs must evaluate all factors with equal importance.

 

THERMAL CONTROL

Another key factor to evaluate while selecting a vertical machining center is thermal control. Modern thermal-control technologies have made significant advancements in both the productivity and accuracy of machining centers. Some key thermal-control characteristics to consider are spindle warm-up times, spindle growth and temperatures of linear axes.

 

MACHINE CONSTRUCTION

Additional means for evaluating the accuracy of a vertical machining center would lie in the construction of the machine. Manufacturers should be wary of thin frames, structures with overhangs and unsupported components or motion. Machines with these components can face distortion, deflection, inaccuracy and vibration dampening when machining. Manufacturers should also pay attention to the weight and mass of the machine and how the machine is arranged to provide stiffness, rigidity and ultimately accuracy. If a vertical machining center is not rigid and stiff, the X-, Y- and Z-axis thrust can suffer, resulting in lower positioning accuracy and repeatability.

 

PRODUCTION SUPPORT

The last key factors for manufacturers to evaluate before investing in a vertical machining center are general production support features, which encompass chip and coolant management, ergonomics and ease of operation.

 

THE IDEAL PRODUCTION SOLUTION

By evaluating VMCs based on the factors discussed above, manufacturers can ensure the ideal solution for their production environment. Each key factor holds a tremendous impact on productivity, quality, efficiency and ultimately profitability. No two VMCs uphold the same standards, even among market leading machines. In order for manufacturers to see through the clutter, it’s important to keep in mind the factors that will make the biggest impact on their ability to compete globally.
