Folder specific design
To
improve the milling fixture installed in the machine tool stability, Precision CNC machining parts reduce its intermittent
cutting may be caused by vibration, not only in the specific folder have
sufficient stiffness and strength, their height and width ratio should also
beappropriate, a general H / B ≤ 1 ~ 1.25, in
order to reduce the fixture center of gravity, so that as close as possible to
the workpiece surface countertops.
Precision CNC machining parts In addition, we must set a reasonable
and ear blocks to strengthen the tendons.
If the folder specific wide, can be set up in the same side of two
T-slot milling machine table equidistant between the ears Block; of heavy-duty
milling fixtures, specific folders should also be set up at both ends of the
rings, such as lifting holes or to carry.
In the milling process, the often installed in the milling fixture
table, together with the jig with the workpiece feed table for movement.In the
milling process, the often installed in the milling fixture table, together
with the jig with the workpiece feed table for movement. According to the
workpiece feed means of general milling fixture can be divided into the
following two types:
1.
Linear feed-type milling fixture 。In the milling
process, the often installed in the milling fixture table, together with the
jig with the workpiece feed table for movement.
2. Circle feed milling fixture.Such
fixtures are commonly used in the milling machine with rotary table, the
workpiece table, together with the fixture with the continuous, slow movement
of the rotary feed, no parking will be loading and unloading the workpiece.
According to the processing requirements of the two cutter head can also be
rough at the same time, finishing
Precision CNC machining parts Milling is a flat, keyway, gear and a variety of forming surface
processing methods commonly used. Processing the workpiece in the milling
machine, the general adoption of the following types of clamping methods:
(1) directly in the milling machine table clamping a large workpiece
clamping often directly in the table, with stud, plate compactor, which need to
dial indicator methods, tools such as zoned to find the needle surface and the
cutter is processing relative position.
(2)
vice flat tool used for clamping the workpiece in the shape of a simple, small
parts, general machine tools can be used in clamping vice in the mouth, the
need to ensure that when used in machine vice the correct position.
(3)
dividing head with the workpiece clamping, the need for indexing of the
workpiece, the general direct clamping head in the sub-degrees. In addition,
indexing of the workpiece without dividing head with clamping processing is
also very convenient.
(4)
with V-shaped frame workpiece clamping method is generally applicable to.
