The DF-MX20 CNC Carbide Step Cylindrical Grinding Machine represents a pinnacle in precision machining technology, specifically designed for cylindrical and taper grinding of round bar workpieces. Tailored to meet the rigorous demands of tool manufacturers and precision parts producers, this advanced CNC grinder excels in processing tool blanks with complex geometries, particularly step differences in diameters and excessive tapers. It blends industrial robustness with high-precision capabilities, making it indispensable for operations requiring unparalleled accuracy and surface finish quality in hard materials like carbide.
Advanced Technical Design
Precision Engineering at Its Core
Engineered with a focus on superior dimensional accuracy, specialized carbide grinding spindle runout of less than 0.005mm, and workpiece spindle runout within identical limits, the DF-MX20 ensures micro-level precision. This capability is vital for applications where tool integrity—such as cutting edges of drills, reamers, or end mills—depends on exact tolerances.
Automated and Manual Flexibility
Automated Mode: Handles workpieces up to Ø12mm in diameter and ≤100mm in length, ideal for high-volume batchesmm** in diameter and ≤150mm in length, supporting larger, bespoke components
