- Recently, a customer from Saudi Arabia requested a stamping die for our wire edm cutting machine workshop. The workpiece measured 205 x 205 mm and required our wire-cutting followed by full welding. The processing efficiency was to produce three complete sets of dies per day. Furthermore, a 5° taper was required to address irregularities in the inner bore. The optimal surface roughness was 0.8 μm.
- Based on the customer's requirements, ANTISHICNC engineers successfully matched the customer with a 400GS3 medium-speed wire cutter. Its X, Y, and Z-axis travels are 400 x 320 x 260 mm, and its worktable has a maximum load capacity of 400 kg. The wire edm cutting machine utilizes an advanced CNC system, enabling 3D tracking during taper processing and enabling single or multiple cuts, improving processing speed and finish quality.
The 400GS3 features a C-shaped structure for stability and improved precision retention. Each moving part of the machine tool utilizes point-to-point lubrication to ensure unobstructed oil flow. The 400GS3's linear guides and ball screws are from Taiwan's Hiwin brand and are directly connected to AC servo motors for enhanced precision. The X/Y axes are controlled by AC servo drives. The machine utilizes the AutoCut system, which supports graphic-driven automatic programming. Users can begin machining by simply defining the machining process based on the graphics, without having to interact with code.
The following are the basic parameters of 400GS3
| Basic Parameters | unit | 400GS3 |
X, Y, Z Axis Travel | mm | 400*320*260 |
X/Y Positioning Accuracy | mm | 0.01 |
Optimal Surface Roughness | um | Ra=0.6 |
Maximum Table Load | kg | 400 |
Maximum Cutting Taper/Workpiece Thickness | / | ±6°/80 |
ANTISHICNC engineers briefly introduce the process of 400GS3 stamping die processing:
1. Material preparation and positioning
- The workpiece must be made of conductive material (die steel).
- The workpiece clamp is mounted on the wire cutter table, usually centered.
2. Process Execution (Critical)
Main Cut (Roughing)
Remove material from the mold contour at high speed, leaving an excess.
Multiple Cuts (Finishing)
- The primary purpose is to improve dimensional accuracy and surface finish.
- The first trimming cut removes some of the excess and deteriorated layers left by the main cut. The parameters are more refined than those of the main cut.
- The second trimming cut further reduces offset and energy, primarily to improve surface quality.
3. Post-Processing
Inspection
Dimensional Inspection: Use a projector, CMM, calipers, micrometers, or other tools to verify that key dimensions are correct.
Surface Quality Inspection: Observe the cut surface for defects such as burn marks and short lines.
4. Assembly
The processed punch, die, and other parts are assembled with the other die components to complete the manufacturing of the entire stamping die set.
