Proper Tire Maintenance: The Air Pressure in Your Tires

You probably know by now that the proper tire maintenance like checking the air pressure in your tires can play an important role in determining car’s fuel economy and drivability. What you might not know, however, is that higher temperatures come with a different set of tire pressure issues.

Combine the Arizona heat with the friction of air pressure in your tires running on hot pavement, and tires can get very hot very quickly. Your tires will always have recommended tire pressure embossed on the sidewall; there should be two tire pressure specs, one for normal and one for hot conditions. Air expands under hot conditions, so be mindful of the tire pressure spec for hot tires when checking for proper tire maintenance.

Remember, too, that under inflation puts a lot of stress on a tire. That stress is multiplied when a tire is hot and running on hot pavement; at that point, it’s more than a fuel efficiency issue, it’s a safety issue. That under inflated, overheated tire could easily fail and come apart, leaving you by the side of the road with a shredded tire or worse. Don’t take that chance! Take the time to air pressure in your tires.

On the other hand, don’t get to overly-enthusiastic about inflation either. Overinflated tires can lead to a harsh ride, squirrelly handling and drivability, and uneven wear on the tires.

The solution? Just go by the proper tire maintenance for hot tires on the sidewall (check them, of course, once they’re already heated up), using a ratchet set. If you’re in doubt, talk to your tire dealer about the specs for your particular tires. And check the air pressure in your tires before you set out on a long trip. Even one tire under inflated by 10 PSI can knock 5 percent to 10 percent off your fuel economy – multiply that by four and you’re taking a hit of 20 to 40 percent, and gas is too expensive to waste it that way!

How Does a Milling Machine Work?

There are many different kinds of Milling Machines.

Machines known as knee-type mills have a worktable that can be altered in a vertical fashion. This work table is put on top of a saddle. The saddle goes on top of what is referred to as a “knee”. A knee is a very large casting that goes back and forth, from left to right, across the milling machine’s pillar. The knee can also be fastened to this pillar in such a way as to ensure it will not move. This allows the milling head and general machine to be placed correctly, and this optimizes the results of the mill’s level of operation.

In contrast to this, what is referred to as a plain vertical machine is very different. With this machine, the spindle isn’t placed horizontally, but rather is placed so as to be parallel to the pillar. This spindle is then attached to a mechanism referred to as a “head”. The head can go up and down the spindle by means of either hands or some source of electric power. Newer models of these machines also posses upgraded features, such as a head that can turn in a variety of directions, thus making it possible to work with surfaces that are not straight.

The construction of the turret and swivel head that accompany these types of mills has been created in such a way as to make sure that the mill’s work is completely accurate, and that the cutting apparatus can be moved in a complete circle. This way, it is possible to make precise cuts at an angle simply by moving the swivel head to any spot within a half-circle.

The pillar that goes with the plain horizontal milling machine has a number of special features. For instance, this is where you can find both the motor and the gears which allow the milling machine to work. This is where you will find the spindle, as well. In addition to this, the plain horizontal milling machine is also accompanied by an overhead arm, which adds an additional level of support to the apex of the spindle. This allows for the securing of long arbors. These levels of support can be altered by moving the position of the overhead arm in order to lend the arbor more stability in a variety of situations.

The worktable that accompanies the milling machine, also known as the knee, travels vertically across the pillar on a fixed track. This allows for a variety of interesting and intricate cuts to be made along the surface of the material being altered. One can easily make dovetails, keyways, and other accents simply by controlling the milling cutters, reamers, and gears. Additional attachments also make it possible to perform even more intricate tasks. The worktable can be adjusted up or down for comfort. The saddle which is placed above the worktable moves back and forth in a dovetail pattern, in order to maintain power over the worktable. This allows the knee to move horizontally under the saddle, so that the surface which needs to be cut can easily make its way toward the cutting device.
