Weeke CNC Machining Center, Model BP-140 ATC Optimat

Transcription

1 Weeke CNC Machining Center, Model BP-140 ATC Optimat Weeke's BP-140 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-140 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.

2 Tech. Spec Page 2 The BP-140 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. 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. 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. 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.

3 Tech. Spec Page 3 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 rpm. Spindle rotation, RH or LH, is also programmable. The inverter has a 14.0 KVA power rating. Auxiliary Vertical Router 5.0 kw 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 19 Spindles The vertical boring head is located on the right side of the spindle carriage and has nineteen (19) spindles. Eight (8) spindles aligned in the X-axis are typically utilized for row hole boring. Ten (10) 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 Four Individually Selectable Spindles The horizontal boring block has four (4)spindles. The drill spindles are positioned to the left, right, front, and back of the machining head. (0, 90, 180 and 270 ). Grooving Saw

4 Tech. Spec Page 4 The X-axis grooving saw is powered by a 1.5 kw, 60 Hz motor. It is installed at the front of the machining head. 100 mm diameter saw blades are used for this unit. 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. 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. Vacuum Pump A powerful vacuum pump with 100 M 3 /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

5 Tech. Spec Page 5 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 the IPC is a Pentium 100 Mhz Windows based machine 1.0 GB hard drive 16 MB of RAM floppy disk drive 3.5" the IPC is connected to a NUM programmable logic control for accurate and reliable control of all machine functions high resolution color graphics (VGA) with 14" color monitor full function industrial keyboard bar code reader interface and software included simultaneous three-axis linear control Optional EtherNET interface for local area network (connection to office PCs) fully compatible and integrated with Holzma Cut-Rite Plus software report generation software included post processor for Pattern Systems Drill Mate included RS-232 serial interface for simple PC connection

6 Tech. Spec Page 6 Off-Line Programming In addition to the software in the machine control, a program is included (on floppy disc) for a PC. Using a PC in the office, the machine can be programmed off-line with the same intuitive icon driven software that the operator has within the machine control. The PC software has no copy protection. If you have a network, you may install the software on as many PCs as you like without buying additional copies of our software.
