BASIC TEORY OF COMPLEX MILLING

PART OF MILLING (a) Column and knee (vertical), (b) Column and knee (Horizontal)

MILLING Turret milling machine of Vertical horizontal

MILLING COMPLEX (VIDEO) www.youtube.com

CLASIFICATION OF MILLING OPERATION Clasification of milling operation : a) slab milling b) face milling, c) end milling

MILLING OPERATION METHODE (a) Up milling dan (b) Down milling

DOWN MILLING Catter simillir with a few catting tool of lathe Kinds cutter of Horizontal and vertical milling machines

MILLING TYPE Column and knee milling machines Bed type milling machines

MILLING TYPE Special purposes. Milling machine with two Spindle Bed type CNC milling machine

CUTTING PARAMETER OF MILLING MACHINES v = Cutting speed (m/minut) d = Diameter of Cutter (mm) n = Rotation of work piece (rpm)

Feeding per toot (ft) and feeding per rotation (fr). CUTTING PARAMETER Feeding per toot (ft) and feeding per rotation (fr).

MILLING CUTTER GEOMETRI Name of part slab milling cutter

MILLING CUTTER GEOMETRI Name of part slab milling cutter

EQUIPMENT AND ACSESSORIES OF MILLING CUTTER Arbor

EQUIPMENT AND ACSESSORIES OF MILLING CUTTER Offset boring head Hoolding tool (end mill) (b) Holding tool shell end mill.

HOLDING WORK PIECE AT MILLING MACHINE (a) Plain vise, (b) Universal Chuck

HOLDING WORK PIECE AT MILLING MACHINE Dividing Head Fungsi: untuk membuat segi banyak, roda gigi, atauhelix. Meja yang dapat diatur sudutnya dalam beberapa arah Fungsi: untuk alat bantu pengerjaan benda kerja yang memiliki sudut lebih dari satu arah.

HOLDING WORK PIECE AT MILLING MACHINE Line finder Parallel vise stop Line finder is attached.at collet
