Technologies has taken the bull by the horns in milling machines as a great deal as is has in any of the manufacturing technologies. The enhanced skills of these machine kinds, as well as the new cutting tool technologies, have vastly enhanced for the point exactly where milling machines are operating at lightning speeds as when compared with just 30 years ago.
With the improvements in milling machine capacities comes an improved want for education and education in the methods http://www.wardcnc.com/ needed to operate these pieces of gear safely also as properly. Some of the key safety places that ought to be viewed as are:
Severe injury, or even death, can occur if a part shoots out in the machine at high velocities and were to strike the operator or some other innocent bystander.
With newer milling machines capable of traveling over 1,000 inches per minute (that's over 83 feet per minute to put it into a different perspective) and many cutting speeds for some materials in excess of 100 inches a minute, the clamping ability from the function holding devises is of critical importance. With cutters moving into the perform piece at significant RPM's and feed rates, the potential for throwing the operate piece out of your machine has been significantly enhanced.
Therefore, it is important that the machine operator loading the parts into these machines be ever-vigilant in making sure that clamps and vises are properly actuated for the appropriate clamping pressures and that parts are loaded onto their fixture points correctly. Process documentation should define the correct torque ratings for the clamping mechanisms at the same time as designating the proper tools to use to verify that these specifications have been met.
Cutting tool situations
There is a constant danger that cutting tools could "explode" while performing their function in milling machines and shards could easily injure anyone near the machine at the time that this occurs.
It is common knowledge among those that have performed machining for many years that sharp tools cut freer and require less horsepower to do their job than when the tool becomes dull, chipped, or losses a cutting tooth. Therefore, it is important that management takes the necessary steps to educate and train its machine operator's in how to determine when tools are getting dull or otherwise must be replaced.
Fortunately many milling machines have been developed have controller's that will monitor spindle horsepower draws and automatically stop the machine (or exchange the worn tool for a fresh tool) if a certain horsepower draw is exceeded. Operators should be trained to monitor these features and exchange fresh tooling for worn tooling before reaching this point.
Proper machine guarding & security glasses
Modern milling machines today have sophisticated enclosures in many cases to contain the chips that fly off on the materials as the cutting tools are doing there job, to contain the cutting fluids used to lubricate the operate piece and the cutter, and to create a protective shell in the event that a cutter should break or the part is thrown out in the fixture. Under no circumstances should these protective guards be removed or circumvented from performing their function.
Moreover, every machine operator should wear protective security glasses at all times. Even using the protective guards on the machine, the operator should not become complacent as to the level of there eye security while being around a milling machine that is in operation.
