Used WEEKE BP-150 CNC Machining Center (1998)

Weeke CNC Router: This BP-150 is a truly industrial machine designed primarily for pointto-
point boring and machining of flat components without special
workpiece fixtures.

Weeke is uncompromising with high quality standards. Weeke uses world
class suppliers for critical items not made in house. In fact, most of the
externally sourced components are sold and serviced on a worldwide basis
and, of course, here in the U.S. Insistence on quality and highly
industrialized components results in a very stable process--one that
requires a minimum of inspection, preventive maintenance, or repair.
The BP-150 is constructed on a steel frame, with heavy steel ribs (gusset
plates) welded to the frame inside the base to insure stability. The design
and substantial mass provide a solid, vibration-free platform for the
machining head. The head rides on THK linear motion guides. In fact, the
X-, Y-, and Z-axes are all supported on THK machine tool guides. THK
guides were designed to produce straight line tracking at high travel rates,
and they have outstanding stability--both in the radial and side directions.
The X- and Y-axes are driven by a zero-backlash, helically ground rack
and pinion gear system. The Z-axis is driven by high precision ball screw.
Indramat solid state drives and digital AC servo motors are utilized to
move the axes. Fiber-optic cables are used for communication between
the drive system and the Homatic controller.

The BP-150 features a Homatic 2000 continuous path control with
intuitive programming software. In addition to the software in the machine
control, a program is included (on floppy disk) for a PC. With a PC in the
office, the machine can be programmed off-line using the same intuitive
icon driven method the operator has in the machine's computer control.

Vertical Routing With Automatic Tool Changer (ATC)

A liquid cooled 7.5 kW vertical router motor with an automatic tool
changer (ATC) is located on the right side of the spindle carriage. The
spindle motor, utilizes grease sealed ceramic bearings for higher
performance and maximum bearing life. This spindle also uses the HSK
standard for the taper in the spindle and the accompanying tool holders.
The HSK design is the latest technology in tool holding systems and has
been proven to be stiffer (less deflection) and much more accurate than
conventional tapered shank designs, especially at high rpms.
Additionally, the exceptional mass and rigidity of the machine's frame
helps the router achieve a good surface finish with high feed rates and
long tool life.

The router motor is equipped with a ride-along automatic tool/aggregate
changer to perform tooling changes during program execution. This
function can be a great advantage when different tool diameters and/or
profiles are required to complete a given workpiece. A magazine for eight
(8) tools rides along on the backside of the spindle carriage and is
protected against dust by a retracting door. The magazine accepts HSK
tool holders with tapered shanks. HSK is available in left or right rotation
(CW or CCW), with a complete selection of collet sizes in inch or metric
increments. Additionally, an entire array of drilling/sawing/routing
aggregates are available for this machine. Orientation of these aggregates
is controlled by servo motor and is programmable from 0° to 360° around
the Z-axis. A 180 mm diameter saw aggregate is included with the
machine. Other aggregates are listed separately under optional equipment.
Two (2) HSK tool holders are included with the machine (with two (2)
collets and a set of wrenches). Additional tool holders and collets are
available and are also quoted under optional equipment.

Frequency Inverter

A solid state frequency inverter manufactured by KEB is utilized to power
the router. The inverter output is programmable through the Homatic
control with constant power from 9000 rpm to 18000 rpm. Spindle
rotation, RH or LH, is also programmable. The inverter has a 17.0 KVA
power rating.

Auxiliary Vertical Router

A 5 kW vertical router with 25 mm ETP hydro clamping chuck is supplied
in addition to the main router spindle. This router motor, supplied by
Perske, features an integrated rotor and tool spindle with a hydro clamping
chuck. This one-piece assembly, manufactured by ETP of Sweden for
Weeke, combines the motor rotor and the tool chuck in a single integrated
part for highest precision. In addition, hydraulic clamping pressure assures
perfect centering of the tool because the tool is clamped with no axial or
radial stress. These special router features, combined with the exceptional
mass and rigidity of the machine's frame, give the best possible surface
finish with higher feed rates and longer tool life. An ETP toolholder is
included to adapt the 25 mm chuck to inch increment router tools (i.e.
1/2", 3/8", etc.). One (1) ½” collet is also included.

Vertical Boring with 31 Spindles

The vertical boring head is located on the right side of the spindle
carriage and has thirty-one (31) spindles. Fifteen (15) spindles aligned in
the X-axis are typically utilized for row hole boring. Fifteen (15) spindles
are also aligned in the Y-axis and are typically utilized for construction
hole boring. These spindles are on 32 mm center distances. They utilize
standard boring bits, 70 mm long, up to 20 mm in diameter, with 10 mm
diameter smooth shanks. One (1) special spindle, for large drills up to
35 mm diameter, is offset from the in-line boring heads. The vertical
boring gear box is driven by a 1.5 kW motor.

Horizontal Boring with Six Individually Selectable Spindles

The horizontal boring block has two (2) spindles oriented to the right, and
two (2) to the left (X-axis), on 64 mm centers. There are also two (2)
drilling spindles in the Y-axis. One (1) spindle is oriented to the front, and
one (1) spindle to the back of the machine. Note: maximum horizontal
boring depth is 45 mm.
5.0 kW

Panel Support Benches

Eight (8) panel support benches have two (2) vacuum pods each. The
support benches have a control button conveniently located on the front to
disengage the pneumatic brakes for the X-axis adjustment of the bench.
The vacuum pods are matrix type, 145 mm x 145 mm. With the vacuum
seal rubber configured for the most narrow part, it is possible for the pods
to hold 50 mm wide strips. With eight (8) support benches and the dual
central zero stop, it is possible to load the machine with four (4)
workpieces at a time.

Metric scales are located on the machine for easy positioning of both the
panel support benches and the vacuum pods along the benches.

Panel Feeding Rails

Panel feeding rails are attached to one side of each support bench (can be
moved to either side). The rails move upward to provide a smooth surface
for loading and unloading. The rails retract downward to set the panels on
the vacuum pods.

Central Zero Stops

Central zero stops are mounted to a center support beam. The central zero
stops are separated by 300 mm, so it is possible to horizontally bore
between the stops. Automatic mirror image function is provided with the
central zero stops, making it possible to put two (2) sets of left and right
(four) panels on the work table at one time.

Vacuum Pump

A powerful vacuum pump with 100 M3/hr capacity has enough reserve
suction for the most demanding jobs.

Dust Extraction Efficiency

Dust extraction efficiency is maximized by a central dust collection
manifold, 250 mm in diameter, with individually controlled connections
to the router, vertical boring block, and grooving saw. As each router,
grooving saw, etc. is activated, dust ports to other devices are
automatically closed. The dust brush cover for the main router spindle can
be programmed in length in order to accommodate different lengths of
router bits.

Perimeter Fence

A perimeter fence helps prevent accidental intrusion from the ends or back
of the machine.

Safety Photocell Barrier

A safety photocell barrier will assist in stopping the machine if the
operator enters the working area while the machining head is in operation.
The photocell barrier is divided into two (2) working zones so you may
load or unload parts at one end of the machine while the machine
continues to work on the opposite end.

Weeke 2000-IPC

The machine is equipped with the Weeke 2000-IPC continuous path
control with intuitive programming software. The Weeke control features
a graphic operator interface with icons to simplify operation.
Programming is with simple coordinates or by the entry of formulas to
define the relationship between panel size and hole locations (parametric
programming). Some of the features of the Weeke 2000-IPC CNC control
include the following:
• Industrial Personal Computer (IPC) for operator interface
