PRG-DX Series

The Okamoto PRG-DX Series elevates rotary grinding productivity through an optimized machine design focused on efficiency and precision. Its wheelhead travels only half the diameter of the rotary table to achieve full contact grinding. As a result, cycle times are reduced while maintaining uniform material removal across the work surface. This streamlined motion enhances throughput without compromising surface finish quality. Moreover, the configuration supports both single and multiple workpiece setups with consistent accuracy. Consequently, the PRG-DX Series meets the demands of high-production precision grinding environments while maximizing operational efficiency.

 

PRG-DX Features:

  • Rigid heavy Meehanite cast construction. Superb Accuracy.
  • Powerful 10hp grinding spindle motor stands up to continuous production grinding.
  • No table overhang assures optimum accuracy.
  • Easy-to-use MDI Control.
  • Ergonomically designed for optimum operator convenience.
  • Versatile table swivel +/-5 degrees.

Description
High-Performance Rotary Grinding Capability

The PRG-DX Series exemplifies advanced Okamoto rotary grinding performance with a focus on precision and production efficiency. Equipped with a powerful 10 hp spindle motor, the machine delivers consistent torque and durability for continuous grinding operations. As a result, it maintains stable material removal rates even during extended production cycles.

 

MDI Control for Simplified Precision

The integrated MDI control system enhances usability while preserving full process capability. Therefore, complex grinding routines become easier to program and manage without compromising accuracy. This balance of accessibility and control allows operators to maintain repeatable precision across demanding applications.

 

Rigid Design for Superior Accuracy

The precision-engineered structure eliminates table overhang to improve stability during operation. Consequently, each grind benefits from enhanced rigidity and reduced deflection. This design is critical for achieving optimal dimensional accuracy and high-quality surface finishes. Ideal for industries requiring strict tolerances and meticulous surface integrity, the PRG-DX Series supports modern production demands with reliable performance and operator-focused design.
