一.How to set up the parameters for table top wire edm machine?
Mid speed wire cutting is a process of reducing material deformation and errors caused by molybdenum wire loss through multiple cuts, resulting in relatively improved processing quality. The processing quality can be between high-speed wire cutting machines and low-speed wire cutting machines.
A regular high-speed wire cutting machine can directly cut the workpiece with one cut. But medium speed wire is a process that imitates slow speed wire. To set up the parameters for table top wire edm machine. When making the first cut, reserve 5% -10% of the convex platform to prevent the workpiece from falling off, and then proceed with a trimming. During this process
The system software will change the parameters and adjust the wire speed to the corresponding speed by reducing the parameters and high frequency. Imitate the process of slow wire cutting for knife repair. Finally, cut the convex platform. If the convex platform also needs corresponding trimming, it can imitate the slow wire cutting process, plug the remaining gaps with copper sheets, and then stick them with 502 glue. After that, perform trimming on the convex platform, so as to obtain a complete workpiece.
The implementation of the wire cutting trimming function in wire cutting first requires the system to be able to automatically jump parameters, and the system must support trimming. If not, relying on manual switching of parameters is not advisable. Secondly, a high-frequency power supply is required to be able to switch to smaller parameters, and a frequency converter is needed to achieve the conversion of wire transport speed. When repairing the knife, adjust the speed of the wire to gradually decrease, making the molybdenum wire run more smoothly, which can achieve better smoothness.
二. Mechanical structure and precision cornerstone
1.Bed material: usually made of natural granite or polymer concrete. These two materials have extremely high damping characteristics and thermal stability, which can effectively absorb vibrations and suppress thermal deformation, providing a stable foundation for high-precision machining.
2.Transmission system:
3.High end configuration: Linear motor. Direct drive, no reverse clearance, extremely fast speed, minimal wear, is the ideal choice for achieving the highest precision and surface quality.
4.Mainstream configuration: Pre tightened high-precision ball screw. By pre tightening to eliminate gaps and using precision linear guides, a balance is achieved between ensuring accuracy and controlling costs.
5.Measurement system: Integrated high-resolution grating ruler to achieve full closed-loop control. The machine tool detects the actual position of moving parts in real-time and compensates for it by comparing it with the commanded position, directly eliminating errors caused by thermal expansion and wear of the screw.
