DF-MX20 CNC Carbide Step Cylindrical Grinding Machine: Precision Grinding for Cutting Tools

Product Overview

The DF-MX20 CNC Carbide Step Cylindrical Grinding Machine is a specialized, high-precision solution engineered for the cylindrical and taper grinding of round bar-type workpieces. Designed primarily for tool manufacturers and precision parts producers, this advanced CNC system excels in grinding the outer circles and excessive-level tolerances required for the production of high-quality carbide cutting tools, reamers, and other critical components within the manufacturing ecosystem.

Key Features and Technical Advantages

1. Precision-Grade Machining

• Ultra-High Spindle Precision: Both workpiece and grinding wheel spindles feature runout of less than 0.005mm, ensuring precision consistency essential for high-performance carbide tool applications.
• Dynamic Speed Control: Grinding spindle speeds (0–3500 RPM) and workpiece RPMs (0–1000 RPM) are fully programmable to accommodate diverse material conditions and step-grinding requirements.

1. Flexible Workpiece Handling

• ** Options**: Supports automatic loading for diameters 3–12mm and lengths ≤100mm; manual loading expands capacity to 20mm in diameter and 150mm in length.
• Axial Integration: Dual-axis CNC control for X/Z axis (each with 225mm travel) enables complex grinding paths and multi-step operations without repositioning.

1. Power and Stability

• High Torque Output: 5.5KW grinding spindle motor and 3.5KW main motor offer ample power to process hard carbide materials efficiently.
• Rigid Structure: Engineered with a 2.5T reinforced frame ( minimizing vibration and maximizing stability in heavy grinding.

Operational Applications

Specifically optimized for:

• Step grinding between segmented sections in drill bits and end mills.
• High-precision taper grinding for custom cutting tools.
• High-volume production runs of cylindrical tool blanks.
• Finishing operations for medical, aerospace, and automotive precision parts.
