Machine frais or milling machine is a tool machine used for forming workpieces with a method of cutting materials using cut equipment.
A working item on a Frais machine is attempted by a milling cutter. Unlike the majority of cutting equipment used by the machine, for example, a lathe or a fuse machine, which only has a single side cut, until the Frais knife has many sides of the cutter. There are several types of Frais machine, such as flat frais machine, upright frais machine as well as General Frais machine.
On the Frais machine, the Frais blade is installed in the arbor which has a flat and upright wick. The Frais blade mounted on a flat arbor, generally placed in the middle of the arbor, where one end of this arbor is mounted on the engine spindles so that arbor and Frais knives can turn along the engine spindles.
Meanwhile, the workpiece that is to be done with the machine frais clamped with a clamp equipment, a kind of clamp or a vise clamp mounted on the machine table.
The cutting movement on the Frais machine consists of:
The main movement of the Frais knife in the form of rotating movements
Movement of nutrition from workpiece in the form of straight movement
Main parts of Frais machine and its functions
The main parts of the Nesin frais are: columns, spindles, arms, arbor, tables, saddle, knees, and base machines.
1. Spindles
Spindles are the main shafts of the engine that play a role in rotating arbor and frais blades.
2. Arbor
Arbor is the role of a frais knife. Arbor mounted on the spindle of the machine, so when the spindles turn around until the arbor want to turn also turned. On a flat Frais machine, Arbor has a circular stem that as far as body is a peg groove.
These Arbor types are equipped with a portion of the ring (spacers) that act to clamp the cutting tool so that the Frais blade does not change from its role. In the consumption of this arbor is supported by the support of Arbor.
3. Column (Column)
The column or body of the machine is the support or the role of the engine parts such as arms, spindle, knee, lever, and is the home of the gears-the transmission gears, the drive motor and its pules
4. Saddle
Saddle or table holder is the resting table place. On the base of the saddle there is a plot of the tail of the bird that is paired in a match with the bird's Tail groove on the top of the knee. Thus the saddle can be moved in the transverse direction subtly. Basically moving the saddle means to move the table in the cross direction, because the base of the table is placed by Sade so if the saddle is moved until the table also want to move. Saddle can be locked against the knee, so that the saddle does not change its location while trying to
Thus, the sleeve of this frais machine can be shifted to the machine column by controlling the bolts of the fixing bolt.
5. MAT (Bed)
The base of the machine is the bottom of the engine and the resting place of the main components of Frais machine such as the column and arms and spindle, knee and saddle and the table. Not only that the mat has something cavity or room that is the place to accommodate coolant.
6. Knees (knee)
Knee or knee is the role of saddle, where the knee is supported by a column of machine and lifting rod. The knee can be moved vertically up or down with the method of rotating the lid. As the table rests on the saddle and saddle rests on the knee, until moving the knee up or down means moving the table vertically for approaching or avoiding the Frais blade attached to the arbor. In order for the timing of the knee to be located in a strong position, until the knee can be locked against the column.
7. Arm (Over Arm)
The sleeve on the flat Frais machine has a use like supporter arbor. This lenga is placed on the upper part of the column or machine body. The base of the arm has a dove tail flow that is worth the shape of the bird's tail groove in the engine column as well as the support Arbor (Arbor bracket).
Thus, the arm of this frais machine can be shifted to its role in the column of the machine with the method of loosed the bolt of the.
8. Tables (Table)
Frais machine table is the place where the workpiece is about to be difrais. The placement of the workpiece at the table is attempted by wearing clamp fittings or a kind of workpiece, body, clamp, head divider and head of the loose
Judging from its construction, the machine table frais has a rectangular form with the T-groove on the surface of the T-groove is the place of the bolt-bolt role that is used for the body, clamp, head divider or head off.
The table can be moved lengthened by the method of rotating a hand wheel at the ends of the table. Machine table Frais can also be moved in a transverse with the method of hand wheel or crank arm in the knee. Not only can it be moved horizontally in the direction of the elongation or transverse, this table can also be moved vertically up or down by bending the crank which is generally also in the knee. Make moving the table Frais machine can be tried manually or automatically.
On the general Frais machine, the table can be rotated with a certain angle, so that it can be used for the tilting gears or helical gears.
