HORIZONTAL BORING & MILLING MACHINE-With “W” axis

MACHINE STRUCTURE
● Rigid box-type column and base features
outstanding stability in heavy duty machining.
● All casting are made of high quality cast iron
and are stress relieved.
● Hardened and precision grounded box way
construction for X,Y and Z-axis.
● Telescopic covers for the cross and
longitudinal traverses.
● X,Z and W-axis with ballscrew.
● Spindle headstock balance is accurately
taken and a counter weight permits the head
to travel smoothly and to retain its accuracy
stability.
Facing Head (Option)

WORKING TABLE
● Build-in index table 1200x1400mm ● Table load capacity maximum 5000kg
minimum indexing 1 degree, full ● Table with pneumatic clamping system.
