ACC CHNC Series Double Column Type Surface Grinders

FEATURES:
The ACC-CHNC Series is engineered for large-format, high-precision grinding, delivering exceptional rigidity, stability, and productivity for demanding industrial applications. With grinding width capacity up to 80 inches, the CHNC Series is ideal for manufacturers that require reliable processing of large and heavy components while maintaining tight tolerances and superior surface quality. Built on a heavy-duty double column structure, the ACC-CHNC provides the strength and stability required for consistent performance over long production cycles. Its rigid fixed crossrail design ensures excellent structural integrity, allowing the machine to maintain accuracy even under demanding grinding conditions.

Precision Engineering for Large Workpieces. The ACC CHNC Series incorporates high-precision double Vee guideways, delivering exceptional motion accuracy and load support. This design ensures smooth table travel and reliable positioning when processing large parts that demand both dimensional accuracy and superior finish. To maintain dynamic straightness of the crossrail – particularly in installations where leveling adjustments are limited – the system includes a pre-set crowning design that compensates for deflection caused by grinding wheel shaft movement. Final fine-tuning is achieved through a unique mechanical adjustment mechanism built into the structure. This design allows precise alignment adjustments without removing the crossrail, even after years of operation.

Powerful CNC Control with Easy Programming. The ACC CHNC Series features CNC control with conversational input, simplifying programming and setup for operators. Fully automatic grinding and dressing cycles enable repeatable precision while minimizing operator intervention. These versatile automated cycles improve productivity, reduce manual setup time, and ensure consistent results across a wide range of grinding applications.

Space-Efficient Large-Capacity Design. Despite its impressive capacity, the ACC-CHNC Series is engineered with a space-saving layout, maximizing productivity without requiring excessive floor space. This makes it a practical solution for shops needing large grinding capabilities without investing in oversized machine platforms.

Designed for Modern Manufacturing Needs. The CHNC Series was developed in response to manufacturers seeking compact yet capable large-component grinding solutions – a machine platform that delivers large-scale precision without the footprint of traditional large-bed grinders.

It is particularly well suited for:

• Large precision component
• Industrial tooling and mold application
• LCD manufacturing components
• High-surface-finish parts such as photomasks  and coating nozzles

For applications requiring ultra-fine surface roughness, the ACC-CHNC can be integrated as a front-end grinding system, followed by free-abrasive particle finishing processes to achieve mirror-quality finishes for critical components.

The ACC-CHNC Advantage:

• Large grinding capacity with widths up to 80 inch
• Heavy-duty double column construction  for long-term accuracy
• Double Vee guideways for superior precision and stability
• CNC conversational programming for easy operation
• Fully automatic grinding and dressing cycles
• Space-efficient design for modern manufacturing floors
