Key Features

● Rigid Integrated Structure: The machine bed is made from HT300 cast iron with five-rib internal reinforcement and stress-relieving treatment, achieving bending resistance up to 4800 N/mm² for superior stiffness and vibration damping—critical for consistent performance in heavy-duty grinding applications.

● High-Precision Grinding Wheel System: The ceramic grinding wheel, bonded with CBN or diamond abrasives, adopts a honeycomb pore design to enhance chip removal and reduce grinding heat by 35%, while optimized dynamic balancing maintains vibration within ≤0.5 μm for superior surface finish.

● Precision Cooling System: A five-level pressure-regulated coolant system provides ±2% flow stability, with 360° adjustable nozzles increasing cooling coverage by 55%, and an integrated centrifugal oil-mist separator ensuring a cleaner environment and improved operator safety.

Frequently Asked Questions

1、I only have part drawings. Can you recommend a suitable vertical grinding machine?

Absolutely! As long as you provide the part drawings, whether for a single vertical grinding machine or a complete production line, a recommended solution can be provided in a short time. For a single machine, it usually takes about 10 minutes; for multiple machines, the full proposal can be ready in about 5 working days.

2、Can I customize a CNC vertical grinding machine based on my processing needs?

Yes. I can customize the spindle power, control system, grinding travel, automatic loading/unloading system, and more on a CNC vertical grinding machine according to the size, material, and machining requirements of my specific workpieces, achieving a perfect match with my production environment.

3、Is the quality of the vertical grinding machine guaranteed?

You can use it with confidence. The components are processed by high-precision mother machines, ensuring high machining accuracy and structural stability. Every vertical grinding machine is rigorously tested before delivery and comes with a complete quality inspection report.

4、What is the typical delivery time for a vertical grinding machine?

If I choose a standard model, it can usually be delivered quickly. In-stock models can ship as fast as within three days. If I require a customized vertical grinding machine, the delivery time is usually 30 to 45 working days.

5、What customization options are available for vertical grinding machines?

We can customize the machine structure, external dimensions, cooling and lubrication system, spindle configuration, control system, and automation modules based on actual production needs. The modular design of the vertical grinding machine also gives me more flexibility for future upgrades.

6、What types of workpieces are suitable for a vertical rotary surface grinding machine?

If you are processing large-size workpieces such as flanges, valve bodies, or ring-shaped parts, a vertical rotary surface grinding machine is especially suitable. Its rotary table structure allows me to efficiently finish precision grinding of large flat components.

7、How can I determine whether vertical grinding machine manufacturers are reliable?

We have in-house R&D capabilities, real customer cases, support for customization, and complete after-sales service as vertical grinding machine manufacturers. A stable export record and responsive service ensure long-term, reliable cooperation.

8、How do I choose the best vertical grinding machine manufacturer for my needs?

You need to evaluate from several aspects: whether the machine meets my machining requirements, whether flexible customization is supported, whether the quality is stable, and whether technical service is in place. If a manufacturer performs well in solution planning, after-sales response, and application support, they are more likely to be the ideal best vertical grinding machine manufacturer.
