Laser Glass Cutting Article

Laser cutting is a precision cutting method widely used in industrial manufacturing. Laser cutting allows a level of accuracy unmatched by any other cutting method. A high-powered laser is directed at the material to be cut. The material burns, melts or vaporizes, leaving a high quality finish.

Apart from the common materials such as wood, plastic and metal, laser cutting is also widely used in the processing of glass. Glass has become an important component of a large number of applications. Its use is not just restricted to windows and bottles but has expanded to telecommunications and information technology.

These modern applications require a higher level of accuracy and precision that cannot be matched by traditional methods. Traditional glass cutting methods make direct contact with the surface, increasing chances of unwanted scratches and abrasions. Moreover, material losses and glass dust are other problems faced in the conventional process.

The use of lasers has revolutionized the art of glass cutting. The laser beam is used to produce highly complex and accurate shapes with a fine edge finish. The power of the laser beam ranges between 1000 to 2000 watts. Most laser cutters are integrated into an enclosed machine with state-of-the-art software. Since the laser used is a "class 4" laser, care is taken to keep the user away from direct contact.

The CO2 laser is the most common device used in glass cutting. The advantages of laser cut glass are many. Apart from the superb quality edges, flaking, chipping and micro-cracks are almost completely eliminated. Moreover, laser cut glass is up to 3 times more durable than conventional cut glass. Since cutting oil is not used in the process, the glass washing process is also minimized. Laser glass cutters can be used to cut glass of any thickness with an equal amount of accuracy. From decorative articles and frames to quartz crystal oscillators and display glasses, the use of these devices is limitless.

These days most professionals own more than one circular saw, and with good reason. When choosing a quality saw, there are number of factors to take into consideration.

Most circular saws use a seven inch blade, which is fine for nearly all applications. Larger models are available, but are usually not needed unless you'll be cutting posts and beams on a regular basis.
The amount of bevel that a saw can cut is an important factor. Practically all models can be set to cut a forty-five degree bevel, but certain saws can cut up to fifty-five degrees with ease. While it may not sound like much, the capability to cut a steeper bevel is a handy feature to have.

Take into account the ease of using the saw. Each saw manufacturer uses a different guide on the cutting deck to allow you to monitor the location of your cuts. While it is strictly a matter of personal preference, being comfortable with your cutting guide is important. Likewise, ensure that you are comfortable with the methods of adjusting your saw's cutting depth and bevel amount. Some use locking levers while others use knobs.

Again, it’s a matter of preference, but an important one.

Laser guides are a fairly new feature available on some models, and are especially useful when ripping boards or making long cuts on plywood. Also, many saws now have LED lights just above the blade to help out in dark places.

Two things that are often overlooked when buying a saw are power and weight. Take into account the wattage and just what you'll be cutting. Harder woods like oak require more power, as does making cuts against the grain of the wood. The higher the wattage, the easier these cuts will be. If you'll be using the saw for extended periods of time, the weight is worth considering. While there are few differences from model to model, a few weigh a considerable bit more than the rest.

Most circular saws come with a few accessories. Rip fences are extremely useful when making difficult long cuts, and nearly every saw comes with one. Hard plastic cases help protect your saw and are frequently included with the purchase of a saw, although some saws come with only a cloth bag or with nothing at all. Dust collection bags are available for a few models, and are useful in a closed space where dust is an issue.
With so many options available, it's easy to find the perfect saw to fit your needs. No matter which circular saw you settle on, it will likely be the most frequently used power tool you own.

Removing Drill Chucks And Other Drill Chuck Tips Read more: http://www.articlesnatch.com/Article/Removing-Drill-Chucks-And-Other-Drill-Chuck-Tips/583777#ixzz1F0TCGxZe Under Creative Commons License: Attribution No Derivatives

By: Mallory Kramer Drill chucks can sometimes prove to be a bigger pest than any other tool-part in the shop. It is said that we all shouldn't "sweat the small stuff," but it seems the "small stuff," like our drill chucks, can be the most frustrating of all. Here are some tips to help you keep your cool and get results around a stubborn chuck.

Chuck Removal
Simply removing your drill chuck can sometimes be an insurmountable struggle. Lear to simplify this process with a few quick and easy steps.

-- First, make sure the tool's gear box is set in low, and that the clutch is fully engaged.
-- Fully open the chuck, and you will find a small screw down in the middle of it (sometimes this screw, however, is missing, but don't fret it is easily replaceable, and not necessary to get the chuck off).
-- Remove the screw. Keep in mind that the screw has left-handed threads, and the chuck has right-handed threads.
-- Once the screw has been removed put the small end of a large allen wrench inside the chuck's jaws.
-- Place the tool on its side and, with a hammer, safely hit the long end of the allen wrench counter-clockwise until the chuck comes loose. Some chucks are on very tightly, so be patient and keep tapping.
-- If hammer-tapping doesn't free the chuck, remove the allen wrench and spray some WD-40 down into the inside of the chuck. Let the lubricant set in the chuck for at least one hour.
-- After waiting, reinsert allen wrench and resume hammer-tapping.
-- Repeat lubrication and hammering process until chuck breaks free.

This may take a few attempts, but that pesky chuck is sure to come loose with some good, old-fashioned deliberation.

Seeking Closure?
It's very common for drill chuck to toggle slightly out of place and not completely close. There is a screw inside your drill chuck there is a screw that holds the chuck in place. On occasion these rascally screws are know to wiggle loose from their threads stopping the chuck from making a complete closure. There is a simple solution: Simply locate a screwdriver that will fit the screw's head, and tighten counter clockwise. A mere twist of the wrist should keep your drill chuck closing tightly and securely.
If your wobbly chuck problems proceed, the chuck's threads or the screw itself could be stripped. There are also other factors that contribute to an incomplete closure between drill and chuck. For instance- your chuck could be locked up or rusted, or the fingers on the inside of the chuck could have slipped or broken. At this point it is best to take the drill to a service center in your area for a professional inspection.

Best of luck, and hopefully these tips will help you to not "sweat the small stuff" both on the job and in the shop.
