Weeke CNC Machining Center, Model BHX 500 Optimat

Weeke's BHX 500 Optimat is a flexible CNC machining center designed primarily for routing, boring, and grooving of flat panel components without special workpiece fixtures. The Weeke factory, located in Northern Germany, is uncompromising and maintains extremely high quality standards. They are an ISO 9001 certified machine tool builder. Weeke uses world class suppliers for critical items not made in house. Externally sourced components are sold and serviced on a worldwide basis and, of course, here in the U.S. Insistence on quality, coupled with the use of highly industrialized components, results in a very stable machining center--one that requires a minimum of inspection, preventive maintenance, or repair. The BHX 500 Optimat is constructed on a steel frame, with heavy steel 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 extremely smooth positioning at high traverse rates. They have outstanding stability--both in the radial and side directions. The X-axis is driven by a zerobacklash, pre-loaded helically ground rack and pinion gear system. The Y- and Zaxes are 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 Beckhoff machine control.


The BHX 500 Optimat features a Windows based control with user-friendly WoodWOP 5.0 programming software. In addition to the programming software in the machine control, the WoodWOP program is included (on CD-ROM) for installation on other PC's. With a PC in the office, the machine can be programmed off-line using the same intuitive icon driven software the operator has in the machine's computer control.
