BMV35 Series CNC Vertical Machining Centers
Gaurav variants BMV35, BMV35 T12, BMV35 TC20
Tool Shank Details
The BMV35 series vertical machining
center Gaurav offers great convenience
to tier III and tier IV suppliers to OEMs. It
efficiently performs milling, drilling and
tapping operations. A full fledged
machining center, Gaurav is rigid,
requires small installation space, and
comes with a precise spindle for
sustained high quality performance. Its
high speed and feed rate result in cost
effective machining.
The arm type tool magazine uses
variable pocket coding. Linear motion
guide-ways, variable speed AC spindle
drives, and CNC system with digital drive
are some outstanding features of Gaurav.
Spindle Characteristics
TC20 high speed
20-pocket arm type
tool magazine reduces
non-cutting time
High quality balanced spindle on large
precision bearings eliminates vibration and
offers accurate machining under heavy load
