Repairing Your Own Machine Components

Many industrial concerns have workshops of their own. For the repair of worn shafts, the lathe machine is excellent. Keyway slots can be machined by using a milling machine, while a shaping machine can do machining of large flat areas. A drilling machine does drilling of holes.

A skilled Maintenance Engineer should know how to use all these machines in order to make his own repairs in a safe manner. Very often he has to supervise machinists. The information below should be useful for that purpose.

Lathe Machine

The lathe machine uses a single-point-cutting tool for a variety of turning, facing, and drilling jobs. Excess metal is removed by rotating the work piece over the fixed cutting tool to form straight or tapered cylindrical shapes, grooves, shoulders and screw threads. It can also be used for facing flat surfaces on the ends of cylindrical parts.

The work piece is clamped onto a horizontal rotating shaft by a 3-jaw or 4-jaw chuck. The latter chuck can be used to cut off-centered cylinders. The rotating horizontal spindle to which the chuck is attached is usually driven at speeds that can be varied.

The cutting tool is fixed onto a tool rest and manipulated by hand. It can also be power driven on straight paths parallel or perpendicular to the work axis. This is useful for screw cutting.

Internal turning known as boring results in the enlargement of an already existing hole. The holes are more accurate in roundness, concentricity, and parallelism than drilled holes. A hole is bored with a single-point-cutting tool that feeds along the inside of the work piece.

Shaping Machine

The shaping machine is used to machine flat surfaces, grooves, shoulders, T-slots, and angular surfaces with single-point tools. The cutting tool on the shaper oscillates, cutting on the forward stroke, with the work piece feeding automatically toward the tool during each return stroke.

Drilling Machine

The drilling machine is used to cut holes in metal with a twist drill. By changing the cutting tool, they can be used to do reaming, boring, counter boring, countersinking, and threading.

Milling Machine

The milling machine uses a rotating cutting tool to cut flat surfaces, grooves, and shoulders, inclined surfaces, dovetails, and T-slots. Cutters of many shapes are changed to cut different grooves.

Cutting Tools

Metal-cutting tools are classified as single point or multiple point. The lathe and shaping machine use single point cutting tool while the milling and drilling machines use multiple-point-cutting tools.

Metal is cut either by moving the work piece like in the lathe or by moving the tool like in the shaping machine, drilling or milling machine. Clearance angles must be provided to prevent the tool surface below the cutting edge from rubbing against the work piece. Rake angles are often provided on cutting tools to cause a wedging action in the formation of chips and to reduce friction and heat.

Tool Materials

In order to remove chips from a work piece, a cutting tool must be harder than the work piece and must maintain a cutting edge at the temperature produced by the friction of the cutting action.

Carbon Steel

Carbon steel tools even though comparatively inexpensive tend to lose cutting ability at temperatures around 400 degree F (205 degree C).

High-Speed Steel

High-speed steel, containing 18 percent tungsten, 4 percent chromium, 1 percent vanadium, and only 0.5 to 0.8 percent carbon, permits the operation of tools twice or three times the speeds allowable with carbon steel

Cast Alloys

Cast-alloy cutting-tool materials containing cobalt, chromium, and tungsten are effective in cutting cast iron and retaining their cutting ability even when red hot.

Cemented Tungsten Carbide

The hardness of Tungsten Carbide approaches that of a diamond. Tungsten carbide tools can be operated at cutting speeds many times higher than those used with high-speed steel.

Oxides

Ceramic, or oxide, tool tips consist primarily of fine aluminum oxide grains, which are bonded together. These are very hard.

Cutting fluids

An overheated tool can become blunt and soft very fast. Therefore very often, cooling fluids cools the cutting points of the tool. This serves to lubricate and cool.

Water is an excellent cooling medium, but it corrodes ferrous materials. Sulfurized mineral oil is one of the most popular coolants as it can both cool as well as lubricate. The sulfur prevents chips from the work from melting on to the tip of the tool.

Perform Your Own Automobile Maintenance

Today's cars can typically be expected to pass the 200,000 mile mark with consistent automobile maintenance. With the price of automobiles, you will want to protect that investment by performing regular maintenance. If you can do much of the work yourself, you will save a lot of money in labor. Invest in a good set of tools and choose quality parts when performing your own automobile maintenance.

If you have some skill, but want to learn more look for courses in general repairs and maintenance. These can often be found at your local community center, Community College or an automotive technical school in your area. Consider investing in a good repair manual for your car, such as a Chilton's manual. The internet is a good place to look for articles and information. There are many sites devoted to auto repair and maintenance.

You will want to keep track of all maintenance performed on your car. You can do this in a log, a notebook or on your home computer. There is software available to help you keep track of maintenance. These programs track repairs, maintenance, replacement parts used on the vehicle and fuel consumption. You can use the same software for multiple vehicles.

Most software allows you to create a service schedule and will remind you when it's time to perform maintenance tasks on each vehicle in your household. The software contains a wide variety of tips for car care. In addition, many have reference and diagnostic tools to help you diagnose various problems with your cars. Many companies offer a free trial that can be downloaded on the internet. This allows you to try out the program before investing your money.

Your owner's manual will give you some basic information about when certain maintenance tasks should be done. Most tasks will be listed according to the mileage on the car.

3000 Mile Maintenance

Change the oil in your engine every 3000 miles. The filter should be changed at the same time. Newer synthetic oils are said to last longer without breaking down. When you change the oil, check the fluids, the air filter, tires, hoses and belts. At this time check the battery cables and terminals for corrosion. This can be removed with a wire brush or sandpaper.

5000-10,000 Miles:

Have your tires rotated and balanced every five to ten thousand miles. This helps the tires wear evenly and extends the life. The best tires should be put in the front of the car. Check the tire pressure regularly and check the tread for signs of uneven wear or damage.

15,000 Miles:

Change the air filter every 15,000 miles. A clean air filter improves the fuel economy of your car. A dirty air filter can cause the engine to run rough and stall. At this time you should also check the pads and shoes on your brake system. Check the brake fluid and top it of, as needed. The fluid should be clear. If you notice noise when the brakes are applied or the steering wheel shakes or vibrates, this can be an indication that the brakes need replacing. In this case, don't wait check the brakes and replace as needed.

30,000 Miles:

Check the fluid level on your transmission. The owner's manual will have information about the kind of fluid that should be used in your car. The manual should have directions on how to drain and replace the fluid. The pan gasket should be changed when the fluid is drained. Also at this time, give the car a tune up. Replace all spark plugs and wires.

50,000 Miles:

Change the coolant at 50,000 miles. See the owner's manual for directions on how to perform this task.

Remember to take care of your car's finish. You want the paint to remain in good condition for as long as possible. Wash the car regularly, even in the winter when salt from the roads can ruin the finish. Apply wax to protect the paint from the sun, salt and weather conditions. Don't neglect the headlights, which can become cloudy and won't operate as well. New Lite Headlight Cleaner and Restorer will return cloudy headlights to like new condition.
