VERTICAL MACHINING CENTER RANGE
Victor Taichung - an established ISO 9001 & 14001 company.
center - 55/70/85A/102A
High speed, high production machining centers that can
make light work out of the most demanding of production
schedules.
These machines have been designed to encompass a
minimum footprint yet they have some of the most
rugged and over-engineered features on today’s market.
The heavy duty spindle and headstock have the ability to
absorb some very high cutting forces yet they keep this
machine’s best features with very high rapid feedrates and
a constant 1.5 second tool change are standard features on
these production machines.
Standard features
• Rapid feedrates of 30/30/24 m/min on Vcenter-55/70
and 24/24/20 on Vcenter-85A/102A
• Tool changes of 1.5 seconds
• 8000 rpm spindle with rigid tapping
• Bellows type guarding on Z axis
• Large work table for 4th axis applications
• 3 axis linear guides.
center - 85C/102C/110/130
Machining centers that mix high
production demands with heavy
cutting conditions.
These machines have been fortified with heavy
duty, hardened and ground boxways into their
Meehanite cast columns, which ensure that the all
high radial and axial cutting forces that arise during
heavy cutting are easily absorbed. The headstock
/ boxway surfaces have been bonded with the low
friction composite Turcite B that prevents any stick-slip
movements. These machines use high accuracy linear
guides in the X and Y axis that help produce high positional
accuracies and very high rapid feed rates.
Standard features
• Rapid feedrates of X/Y/Z - 24/24/18 m/min
• Tool changes of 1.5 seconds
• Tool capacity of 24 tools
• Very large work table for 4th axis applications
• 6000 rpm spindle with heavy duty roller bearings
• Spindle oil cooler (optional for Vcenter-85C / 102C)
• Z axis box slideway.

center - 85B/102B/145
Machining centers built to withstand the heaviest of today’s
cutting conditions.
These machines have been designed with very large heavy-duty,
hardened and ground boxways on all 3 axes which allows
these Vcenters to absorb most any cutting forces. The
Meehanite cast columns, saddles, headstocks and beds have
all been reinforced with computer analyzed ribs to guarantee
better damping and rigidity properties. These rugged
machining centers have been tested and proved to make light
work out of some of the toughest machining materials, so let
a Vcenter tackle your roughest jobs.
Standard features
• Heavy duty spindle roller bearings
• Bonded with low friction composite Turcite B
• All boxways with constant forced lubrication
• 2 speed gearbox for high torques at low rpm (optional for
Vcenter-85B/102B)
• 3 axis box slideway.
center - 55/70 APC
Standard VMC with compact high speed APC
Front mounted APC allows easy access to both machine
work area and pallet.
Twin rotary type automatic pallet changer increases productivity
by eliminating set-up times. During machine operation the idle
pallet can be accessed from the front of the machine to allow the
operator to set-up the next workpiece.
The servo driven pallet changer means rapid workpiece change
over to minimise idle times. Conical pins are used to
accurately locate the pallet, while an air blow blast
during pallet exchange removes chips or dirt, which
would otherwise interfere with pallet placement.
Standard features
• Pallet loading capability of 200 kg for increased
working range
• Pallet size 560 x 400 mm(Vcenter-55APC) / 720 x
400mm(Vcenter-70APC) with bolt holes for work
location
• Idle pallet is easily removed to allow use of
additional pallets
• Hydraulic pallet clamping for max. stability during machining
• Direct mounted to machine for easy installation and reduced
floor space
• Servo-driven rotary APC for fast pallet exchange 3 seconds(P-P)
• Front mounted APC with ergonomic design to allow easy
operator access to pallet spindle and machine work area.

Precision machine alignment
• The traditional method of handscraping
remains the most effective way of ensuring
squareness and flatness in machine tools
R
using plain bearing linear ways.
• With over 50 years experience in building
machine tools using this traditional
manufacturing manner, our understanding of
the critical factors that ensure accuracy and
durability are second to none. Highly skill
personnel, trained in-house, are employed
to make sure this handscraping is done to
perfection.
• Ball bar testing is used to verify machine accuracy in
circular interpolation.

• FANUC 0i-M / 21i-M / 18i-M controllers to meet various
requirement for batch production or high speed machining.
• Heidenhain iTNC-530 controller with user-friendly conversational
function to meet mold manufacturing requirement.

Workpiece measurement
To reduce time spent setting workpiece positions and then
manually inspecting finished parts, which would be better invested
in machining, automatic workpiece measurement is available
with the use of Renishaw OMP-60 or Marposs T36G measuring
probes.
With the system provided by Victor the workpiece position can be
identified with the probe and work offsets automatically updated,
enabling parts to be made right first time. During batch production
in-processing checking can be performed on the machine, while
for optimum accuracy in machining part inspection can be done
after roughing so that finished part can maintain tight tolerances.
Linear scales for improved repeatability
Linear scales offer exceptional positioning accuracy up to 0.005 mm over full stroke.
Only Heidenhain linear scales with a thermal behaviour similar to that of the machine
are selected so that thermal expansion can be compensated for further enhancing
repeatability. Sealed encoders with durable Aluminum housing offer improved reliability
and service life.
Automatic tool measurement
To reduce tool set-up time and improve machine operator interface Victor offers 2
automatic tool measuring systems:
Simple tool length measurement
Metrol system T - 20B is mostly for tapping and drilling, as the probe used only measures
the tool length. This simple cost effective system greatly reduces tool set-up time by
automatically inputting tool length values once the tool is tipped off the probe.
Advanced tool measurement
Renishaw system TS - 27R offers further advancement with the probe capable of
measuring both tool lengths and diameters. This system is ideal for batch production
where tools need to be constantly changed or replaced.
4 th-axis CNC rotary table
To improve the machine's application range, a CNC rotary table can be
installed with which 4 axes simultaneous machining can be realized.
This function can eliminate multiple set-ups allowing multiple faces to
be machined with a single set-up.
Furthermore the additional 4th axis allows more complex parts to be
machined such as cam profiles using cylindrical interpolation or angled
holes.
5 th-axis rotary table is also available with tilting as well as
rotary function.
Tilting B-axis is indexable with Fanuc 21i/18i-M or full simultaneous
rotation with Fanuc 18i-MB5 or 16i-M control.

Fully enclosed guarding with optional CE
marking
The machine is designed to meet the strictest
safety standards with fully enclosed guarding
to prevent operator access to the machining
area during operation and coolant leaks in
using high pressured coolant (optinal on
Vcenter-145). All electrical components meet
CE mark requirements while optional door
interlocks and magazine guarding bring the
machine up to full CE standard.
Through spindle coolant
For improved deep drilling and boring capability, coolant can
be forced through the center of the spindle under high pressure
directly to the cutting area. To ensure long and reliable running
of this system, fine particles produced during machining must be
filtered out to prevent damage to the spindle. Victor's customized
cleaning system by centrifugal dispersion or replaceable filter
cores is far more reliable with less maintenance than conventional
system to avoid the fine particles flowing into the spindle.
Oil hole coolant
As an alternative to through spindle coolant, it is possible to supply coolant through the toolholder, using an adaptor
located on the spindle nose. High pressure (Grundfos pump SPK 2-3) can be supplied with no need for sophisticated
filter system as the coolant bypasses the spindle.
