Research And Optimization of Grinding Process for CNC Vertical Double-Sided Grinder

CNC vertical double-end surface grinding machines are widely used in flat grinding due to their excellent processing quality, high efficiency, and non-magnetic properties. Given the diversity of workpieces in practical applications, optimizing the grinding process is particularly important. This discussion elaborates on the grinding principles, grinding wheel selection and dressing, grinding parameter adjustment, and machine maintenance and management.

Grinding Principles of CNC Vertical Double-End Surface Grinding Machines

There are four main grinding methods used:

Vertical rotary through-type: Workpieces rotate through the grinding wheel gap, which is suitable for continuous production.

Vertical pass-through type: Workpieces pass sequentially through the grinding zone with guidance, offering high efficiency.

Vertical swing-arm plunge type: This type provides extremely high machining accuracy, generally within 0.002 mm, making it ideal for high-precision parts such as core components of air conditioning compressors.

Vertical reciprocating oscillation type: Balances machining accuracy and efficiency, suitable for workpieces with small stock allowance and moderate precision requirements.

Selecting the appropriate grinding method according to the material and precision demands significantly improves processing outcomes.

Grinding Wheel Selection and Dressing

The grinding wheel’s performance directly affects grinding efficiency and workpiece quality. Key considerations include:

Choosing wheels with high hardness, strength, and wear resistance tailored to the material characteristics and grinding requirements.

Regular dressing of the grinding wheel is essential to restore its sharpness and correct geometric profile. Dressing tools and techniques determine the wheel’s microscopic surface morphology and macroscopic contour, thereby influencing grinding performance.

Proper dressing exposes fresh abrasive grains, maintains wheel shape and concentricity, removes glazed or loaded areas, and improves turning performance and surface finish quality.

Optimization of Grinding Parameters

Grinding parameters such as grinding speed, feed rate, and depth of cut must be rationally adjusted to:

Enhance grinding efficiency and reduce processing time.

Minimize grinding heat and forces, thereby decreasing wear on the grinding wheel and machine.

Extend the service life of equipment.

Parameter settings should be scientifically optimized based on the specific material and precision requirements to achieve the best results.

Machine Maintenance and Operation Management

Maintaining and managing the CNC grinding machine is crucial for stable performance:

Regular cleaning, lubrication, and inspection of moving parts prevent wear and corrosion.

Timely detection and elimination of potential faults ensure the machine operates at optimal conditions.

Strengthening operator training improves skills and maintenance awareness, reducing human factors that may impact machine performance.
