Die sinking electrical discharge machine D7132

high-accuracyprecisionhigh-productivity

Overview
The D7132 is a 3-axis CNC EDM die sinking machine from the D71 Series. It expands capacity in the D71 Series to provide a larger worktable and heavier workpiece support while maintaining high-precision control and multi-stage EDM capability. The machine is designed to accommodate mold cores, steel inserts, and heavy-duty tooling components and to deliver consistent dimensional accuracy and surface finish.

Basic product data

• Worktable size: 400×250 mm (listed in model details)
• Work tank dimension: 1030×520×320 mm (listed in model details)
• Max. workpiece weight (listed in model details): 250 kg

Expanded / D71 Series capacity (product description)

• φ500 mm (500×320 mm) worktable (expanded configuration)
• Work tank dimension (expanded): 1030×560×320 mm
• Supports heavy workpieces up to 550 kg (expanded configuration)

Key Features

• Z-axis CNC servo motor (Sanyo, Japan) ensures precise control of spark gap and cavity depth
• X/Y axes driven by high-precision ball screws for excellent motion consistency
• Supports heavy workpieces up to 550 kg without loss of accuracy (expanded D71 configuration)
• Intelligent CNC system automates roughing, finishing, and wear compensation
• Stable mechanical structure minimizes thermal drift and vibration for long-hour operations

Recommended Configurations

• Electrode Holder with Rapid Lock — speeds up electrode changeover and ensures concentricity
• Graphite Dust Filtration System — maintains clean dielectric when using graphite electrodes
• Dielectric Oil Chiller — controls fluid temperature for consistent spark conditions
• Z-Axis Precision Probe — automatically detects work surface and enhances depth accuracy
• Multi-Stage EDM Programming Suite — allows programmable discharge cycles for rough to finish
• Automatic Fire Detection Unit — enhances safety when operating with oil-based dielectrics

Application Case

• Client: Automotive mold supplier (India)
• Use case: EDM finishing on high-precision mold cavities for complex plastic housings
• Setup: D7132 equipped with dielectric oil chiller, graphite electrodes, and 3-step discharge control
• Results: Dimensional consistency ≤ ±0.009 mm; surface finish Ra ≤ 1.4 μm; average electrode wear < 0.18%; client feedback: “We’ve replaced two old sinkers with one D7132—it’s more accurate, faster, and easy to program.”

Notes
The page presents both a standard configuration (400×250 mm table, 1030×520×320 mm tank, 250 kg max) and an expanded D71-series configuration (500×320 mm table / φ500 mm, 1030×560×320 mm tank, 550 kg max). Exact delivered configuration depends on selected model/options and customizations.
