Principles of a Bench Grinder

Principles of a Bench Grinder
View Full Size
Basically, a Bench Grinder is an electric motor with a shaft on the right and on the left, with a grinding wheel mounted each. The shafts should be as ball bearing as possible, so that they run perfectly and thus bring reasonable grinding results. The motor runs the two grinding wheels with which the surface of the respective workpiece can be machined. The higher the power of the motor is, the larger workpieces can be processed. Sounds easy, which it is exactly. 
 
The Grinder Disks
 
The main task when working with the Bench Grinder is carried out by the grinding disks. As a rule, grinding disks with different grain sizes are used, common are the grits 24/36/60/80. There is always one disk for coarser and one for finer work. The grinding disks are made of silicon carbide or corundum and are available in the sizes 150 mm, 175 mm and 200 mm. The speed of almost all bench grinders is between 2800 and 3000 rpm.
 
Fields of Application of a Bench Grinder
 
Bench grinders are ideal for metalworking. Whether workpieces are deburred, rounded off, or simply sanded, the bench grinder and coarse grinding disk make this very easy. With the fine grinding wheel, the edges can be removed even finer.
 
Much more important, however, is the ability to sharpen drills or cutting tools, such as knives or chisels. Just make sure that these tools do not burn out during grinding. All bench grinders must be equipped with so-called spark protection glasses. These shatter-proof lenses ensure a clear view of the workpiece to be machined, but they reliably detect the resulting flying sparks.
 
Furthermore, all double grinders are equipped with an adjustable support. The workpiece rests on this support during grinding, so that it can be safely guided despite vibrations. These pads are adjustable because the disc reduces its diameter over time due to wear. The gap between the support surface and the grinding wheel should be no more than two millimeters so that no workpiece can be wedged in it. Regular checks and readjustments are therefore very important.
 
Variants and Special Models
 
There are hundreds of variants that are specifically geared to the respective tasks. For the do-it-yourselfers, there are some standard models, which we briefly list here:
 
Wet-Dry Grinder

 

Especially for grinding work on knives, chisels, drills, etc., the wet and dry grinder is the specialist. One grinding wheel is for rough grinding and the other one is slightly larger, wider and finer. It rotates much slower (about 130-140 rpm) and runs through a water bath to cool the workpiece during grinding. Annealing is prevented by these two factors and provides razor-sharp results.
 
Stationary Belt Grinder

 
Again a machine, you can use on various applications, this time with a rough grinding wheel and a belt sander. These machines are used a lot in the wood sector, whereby the sanding belts also tolerate metal.
 
Sander Polisher
 
This machine not only has significantly smaller discs, but also a long, flexible shaft on which special grinding and separating attachments can be operated, just like with a gravure tool. The coarse grinding wheel and the polishing wheel can be adjusted to the ideal speed by means of a rotary control.

What Is Airbrush Makeup?

 
You may have heard of airbrushing in relation to magazines, and many beauty products boast an “airbrushed finish”, but you may be interested to know what exactly is airbrush makeup? It is a great way of getting flawless makeup quickly, yet it looks completely effortless and enhances your natural beauty – so how can you get it at home?
 
Airbrush makeup is a technique of applying makeup to the skin using an airbrush system as opposed to the traditional method of using brushes, sponges or fingers. The technique is similar to how spray tan is applied, but on a smaller scale because it is typically only applied to the face, although it can be used all over the body. The coverage can range from sheer to full as it is built up in layers so that you can get the perfect look for different occasions for the same product.
 
What Is Airbrush Makeup Used For?

Airbrush makeup is widely used by professionals for photoshoots as it looks fantastic on camera.
 
The makeup is applied in such a fine mist that it complements the pixels in an image, giving a flawless, natural-looking appearance that does not seem caked even with full coverage.
 
It is also favored by professional makeup artists for events such as weddings and proms because not only does it look fantastic in photographs, but it looks beautiful and natural in person too. It can be totally adapted to each person, by building coverage and blending products to find exactly the right match.
 
Airbrush makeup is not only for professional photography and special events though, it is also a great option for everyday makeup because it is so light, quick to apply and looks so natural. Once you start using airbrush makeup, you won’t want to go back to traditional makeup. It not only gives a flawless appearance, but you won’t feel like you are wearing it and it will last all day.
 
What Is Airbrush Makeup For Weddings?
 
Professional makeup artists favor airbrush makeup for special occasions like weddings and proms because it is long lasting and often waterproof.
 
It will not smudge or run if you get emotional or hot and will look natural throughout the day.
 
Airbrush makeup techniques can be used to apply a full face of makeup, even eyeshadows, and will last as long as 12 hours, or even longer. It looks as fantastic in person as it does in photographs and the coverage and tone can be completely adapted to suit each user’s skin.

How To Extend The Life Of A Battery And Restore Its Functionality

修复车电瓶健康来延长车电瓶寿命
 
来自于意大利TELWIN智能充电器,能修复车电瓶的健康来延长车电瓶寿命, 让我们不需要破费换新电瓶。
 
1. 能自动探测电瓶极板硫酸化程度及进行极板脱硫的动作。 ( sulfation & desulfation )
2. 为电瓶脱硫就能有效的修复车电瓶的健康,还能延长车电瓶寿命
3. 不会过度充电,一旦充满电,充电器就会进入维护摸式。 能避免过度充电的危险及保护车电瓶。
4. 还能自动探测电瓶健康的状况.
 
It is essential to know about those situations that can hinder battery performance: one of these is sulfation, which can degenerate battery performance until it is no longer usable.
 
Battery sulfation is caused by many different facts, but the battery remaining for long periods without being used, and therefore subjected to self-discharging, is probably the most common.
 
In addition, the continually growing number of devices in today’s vehicles that constantly require energy even when the engine is switched off, for example alarm systems, can cause the battery to discharge progressively and create the conditions for sulfation.
 
The concept of desulfation follows as a consequence of this, i.e. a process that allows to restore the functionality of the battery by increasing its life and eliminating the necessity of replacing it beforehand.
 
Sulfation 
 
During discharging, the lead plates (electrodes) react with the electrolytic acid solution and create lead sulphate crystals. These crystals deposit on the surface of the plates, which stops the electrochemical process from working correctly, which in turn degenerates battery performance; this situation is called “sulfation”.
 
When a battery is recharged, the crystals should be re-absorbed by the electrolytic solution, and normal conditions be restored, but excessive accumulation of crystals makes it difficult to dissolve them, thus damaging the correct battery operation
 
Desulfation – Recovery
 
The term “desulfation” introduces a forced process that replaces the initial density of the electrolyte solution thanks to the application of special current impulses that disaggregate the crystals (breakage of the molecule bonds between the lead ions and the acid sulphate ions), and restore battery conditions

EINHELL Brushless motor technology from Germany


Abrasion minimised - performance maximised!
 
Maintenance free, high performance and energy efficient: Carbon brushes in conventional electric motors have very negative effects on efficiency and durability. That is why we have equipped our tools with the modern brushless drives. Friction losses or involuntary idle time due to overheated motors is now a thing of the past!
 
Real efficiency
 
Modern technology enables us to design electric motors without carbon brushes. In this way, the brushes, which in conventional electric motors change polarity through mechanical contact with the rotor, change polarity here electronically. They create a rotating magnetic field, that the rotor follows - contact less, abrasion free and high efficiency.
 
High durability!
 
No sparks are flying - but the friendship is blazing strong! Our brushless motors are exceptionally robust, maintenance-free and have a long service life.
 
Maximum performance - no compromise
 
Better performance through fewer friction losses: Our brushless motors enable higher revolutions per minute and more torque compared to conventional electric motors.
 
Longer service life
 
Ideal for large projects: Due to less heat generation, our brushless tools can be operated for longer durations at higher capacities without overheating.
 
Maintenance free
 
Brushless motors have no carbon brushes which cause wear and tear through mechanical abrasion. Compared to conventional carbon brushes based motors, we increase service life signficantly.
 
Compact
 
Brushless motors can be designed more compactly, saving space and weight - for particularly light and ergonomic tools.
 
Efficient
 
More efficiency and endurance: Because brushless motors cause no friction losses, Power X-Change system's battery output can be used very efficiently.
