ERM-12/12A/12H 20/20H

Product Overview: ERM-12/12A/12H 20/20H CNC Tool Grinding Center

The ERM-12/12A/12H 20/20H series represents a benchmark in precision tool manufacturing and re-sharpening. Built with a rigid cast-iron foundation weighing 1500KG and measuring 1650*1550*2000mm, this equipment eliminates micro-vibrations during heavy material removal, ensuring a flawless surface finish on every flute. Operators will immediately notice the smooth, quiet operation of the 7KW electrical spindle as it accelerates to a maximum of 8000 RPM, delivering a peripheral grinding speed of 36m/s. The distinct scent of ISO VG68 rail oil accompanies the fluid motion of the 5-axis servo motors (X, Y, Z, C, A axes), providing a tactile sense of industrial reliability and mechanical precision. Designed to handle tools up to 330mm in length with a maximum blade length of 150mm, this machine accommodates a wide range of end mills, drills, ball end mill cutters, and tap cutters. The integration of a BT30 grinding wheel shaft supporting up to four grinding wheels allows for rapid changeovers, significantly reducing idle time on the production floor. The robust architecture is specifically engineered to handle continuous, multi-shift operations without compromising on the tight tolerances demanded by modern machining standards.

Proprietary CNC Software and Manufacturing Excellence

As a leading manufacturer of tool automation production equipment, tool grinding equipment, and similar precision machinery, the facility integrates decades of mechanical engineering with proprietary digital solutions. The core of this machine’s performance lies in its self-developed multi-axis linkage grinding software. This intuitive interface transforms complex tool geometries into simple, manageable parameters, drastically lowering the learning curve for new operators while boosting overall production efficiency. The tactile response of the control panel and the visual clarity of the software interface provide immediate feedback during setup, making tool production and grinding easier, more convenient, and more efficient.

Furthermore, precision is guaranteed through the standard inclusion of a high-accuracy contact 3D probe detection system. This advanced probing technology maps the tool surface before and after grinding, achieving a repeated positioning accuracy of 0.003mm and an A-axis hole inner taper beat of 0.002mm. Such exacting tolerances effectively control runout on small-diameter tools and prevent edge chipping on brittle carbide materials. At present, the facility has a series of products with independent intellectual property rights across CNC tool grinding machines, end mill re-sharpening machines, ball end mill re-sharpening machines, and drill re-sharpening machines. Backed by a modern production base equipped with advanced processing equipment, the annual production capacity reaches tens of thousands of units, ensuring consistent, reliable performance for high-volume manufacturing environments.

Ideal of manufacture and re-sharpening of vice and blade

This equipment is engineered to meet the stringent demands of specialized industries where tool failure is not an option. From the heat-resistant superalloys used in aerospace components to the micro-precision required for medical bone drills, the ERM series delivers repeatable, exact cutting edges. Whether processing standard high-speed steel or advanced carbide composites, the machine adapts perfectly to the material properties. Understanding that no two production lines are identical, flexible equipment configurations are available. Facilities can request tailored machine setups to accommodate unique tool specifications or specific capacity requirements, ensuring the grinding center perfectly aligns with existing workflows.

Industry-Specific Applications

• Aerospace Components: Capable of maintaining tight tolerances on end mills used for titanium and Inconel machining, ensuring structural integrity.

• Medical Devices: Ensures zero runout on micro-drills and surgical cutting tools, providing the critical precision needed for medical applications.

• Automotive Manufacturing: Rapid re-sharpening of complex step drills and custom profile cutters to keep assembly lines moving without interruption.

• Precision Mold Making: Flawless edge retention for ball end mills and deep-cavity tools, resulting in superior surface finishes on molded parts.

Beyond the physical hardware, a comprehensive end-to-end support structure guarantees long-term operational success. This encompasses professional on-site installation, meticulous system calibration, and hands-on operator training. Technicians guide staff through the nuances of the software and the physical adjustments of the BT30 shaft, ensuring they can hear the correct grinding contact and visually inspect the optimal spark trajectory. Ongoing lifecycle technical response ensures that any mechanical or software inquiries are addressed swiftly, minimizing downtime and maximizing the return on investment.
