Machining Centers: Get to Know the Machining Centers and Its Safety Precautions
A Machining Center, also known as milling machine, is used in the industrial setting for slot and keyway cutting, planing, drilling, diesinking, rebating and routing. Machining centers come in horizontal and vertical forms with size ranging from those that can be mounted on tables and benches to those that could fill a whole room.
The latest models of machining centers also have a C or Q axis, in addition to the normal XYZ axes. This extra degree in freedom allows the engraving of sculptures, like the human head for example, with ease and accuracy.
The machining center functions like a drill press. However, while the drill press holds the metal being worked in place as the drill penetrates the material, the machining center moves the workpiece against the rotating cutter which cuts the flanks and tips with much precision.
And speaking of precision, all machines are intended to operate with a certain level of precision. Generally, the assumption is that the more modern the machine is, the higher is its level of precision. The workpiece and cutter movement of the machining center is also highly controlled. However, its accuracy is also affected by external factors such as temperature, the kind of metal and the condition of all the components that make up the machining center and the operator.
Like any other machine, there are also safety precautions that the operators should observe when using machining centers. This includes the following:
• Avoid contact with the revolving cutter. If it could slice a metal, it could slice your limb as well.
• Line the surface over which to place the machine with a suitable material to prevent it from being scratched or other forms of damage.
• Do not move heavy attachments by yourself. Have someone assist you.
• Do not attempt to tighten arbor nuts using machine power.
• Cover your hands with a rag, glove or anything suitable when installing or removing milling cutters.
• The cutter should be the last to be installed when setting up the machine to prevent you from getting cut while working on the other components.
• Never adjust the workpiece or work mounting devices when the machine is operating.
• Remove chips from the workpiece using a rake and a brush.
• Turn off the machine before making any adjustments in its parts or controls.
• When using cutting oil, prevent splashing by using appropriate splash guards. Cutting oil on the floor can cause a slippery condition that could result in operator injury.
Regular maintenance cleaning of machining centers ensures its longer life span. The internet offers a lot of information on taking care of the specific parts of the machine, as well as the precautionary measures that should be observed in handling the machining center before, during and after using it.
