Stepper Mid-speed WEDM machine

 

1、Characteristics.

1、The main machine adopts high quality 250 resin sand, which has been tempered many times to eliminate internal stress and keep the accuracy of machine tool unchanged for a long time.

2、Filament barrel motion bearing adopts all imported precision bearing, which has longer service life. The guide wheel adopts special high precision guide wheel and all imported bearings, which greatly increases the service life.

3、The filter device of slow-moving silk water tank, special water-based cutting fluid and multi-layer filtering system are adopted. The self-suction pump has better performance and longer service life, which lays a foundation for high precision and roughness of the processing surface.

4、One-stop automatic centralized oil supply device can lubricate X, Y guideways, screw rods, barrel guides and screw rods, and ensure the service life of machine tools.

5、The system is a complete set of WEDM solutions. AutoCut system is composed of AutoCut system software, motion control card based on PCI bus, high reliability, servo drive control motherboard, AC high frequency discharge board and sampling circuit. AutoCut system software includes AutoCAD WEDM module, NCCAD (including WEDM module), CAXA AutoCut plug-in and machine tool control software.

 

In order to ensure the accuracy of each machine, Longkai uses Renishau laser interferometer to check the positioning accuracy and repetitive positioning accuracy of the equipment. The high-configuration guide wheel and guide nozzle are adopted in the silk hauling system. The reasonable layout completely solves the problem of single side loosening and makes the machined surface achieve uniform roughness.

 

Long-life moving parts:

1.The X, Y and Z axes are all equipped with high precision ball screw and imported rolling linear guide, which can run smoothly and keep the accuracy of the machine tool.

2.Imported bearings are used in all moving bearings of machine , so that the reliability and durability of machine tool processing accuracy are higher and the long-term interests of customers are guaranteed.

3.The guide nozzle adopts the design of slow-moving wire. The UV axis is fixed and the guide nozzle can rise and fall automatically, so that it can be as close as possible to the workpiece's machined surface, prevent the molybdenum wire from shaking again, avoid the line marks on the cutting surface, and greatly improve the accuracy and roughness of the machined surface.

4.The tightening system uses two-way automatic tightening device to tighten molybdenum wire in real time. The unevenness and accuracy of the processing plane caused by the inappropriate tightness of molybdenum wire in the process of processing are thoroughly solved.

5.The guide wheel adopts specially made gem guide wheel and customized sprinkler plate. Replacement can automatically return to the origin, greatly reducing the difficulty of replacing vulnerable parts, and facilitating the use of customers.

6.The imported linear guide rail and the imported switch are used for the barrel guide rail and the commutation switch to ensure the stability, high precision and long-term reliability of the barrel at high and low speeds.

 

Main Characteristics of  Stepper WEDM machine

1、Graphic driving technology reduces the labor intensity of workers, improves the efficiency of workers, and reduces the chance of misoperation.

2、For users of Windows XP and other versions, the software is easy to use, that is to say, learning is learning.

3、Directly embedded in AutoCAD, NCCAD, CAXA and other versions of software, the integration of CAD/CAM is realized, and the machinable object of WEDM is expanded.

4、Four-axis linkage control technology is used in the processing of taper workpiece; three-dimensional design of processing trajectory; and compensation of guide wheel radius, wire diameter, unilateral discharge gap and elliptical error of large taper to eliminate the theoretical error of taper processing;

5.With multi-card parallel technology, one computer can control multiple WEDM machines at the same time.

6、It can carry out multiple cutting, with the function of user-maintained process library, intelligently control the processing speed and parameters, so as to improve the surface finish and dimensional accuracy, and make multiple processing simple and reliable.

7、This software optimizes the processing of super-thick workpiece (more than 1 meter) to make its tracking stable and reliable.

8、Connection network management: In order to facilitate the operation of one person and multiple computers, drawing input and export, equipment can realize network connection.
