Rushan Shuangxing Machine Tool Manufacturing Co., Ltd. is one of the leading manufacturers and suppliers of double disc grinding machine for thin valve plates in China. With abundant experience, our factory offer high quality equipment made in China with competitive price. Welcome to contact us for customized service.
This double disc grinding machine is engineered specifically for flat face processing of circular cutting blades. It serves industrial knife manufacturers, slitter blade producers, metal shear suppliers and precision tooling workshops that require consistent two-sided flatness and parallelism on circular cutting components before final edge sharpening.
Unlike general-purpose grinders designed for standard metal parts, this blade-dedicated model is calibrated for the unique demands of cutting tool manufacturing. Its extended travel range accommodates large-diameter circular blades stacked in batches, while the reinforced spindle and vibration-dampening structure maintain the tight geometric tolerances critical for blade performance. The result is a grinding solution built around the specific workflow and quality requirements of industrial blade production.

Core Advantages for Blade Manufacturers
1. Batch Processing Efficiency with Extended Stroke
The 800 mm extended reciprocating stroke allows multiple circular blades to be stacked and clamped in a single setup, completing full two-sided grinding in one continuous pass. This stacked processing dramatically reduces per-blade cycle time compared to single-piece grinding methods, while also minimizing dimensional variation across the batch since all blades receive identical grinding conditions.
2. Precision That Directly Improves Blade Quality
For cutting blades, consistent flatness and parallelism are not just cosmetic specs - they directly determine edge quality and cutting performance. Blades with uneven faces will develop irregular cutting edges during sharpening, leading to shorter service life and inconsistent cut quality. This machine maintains parallelism within 0.008 mm, providing a perfectly uniform foundation for subsequent edge grinding and honing operations.
3. Optimized for Hard Blade Materials
Circular cutting blades are typically made from high-speed steel, tool steel or cemented carbide - materials that are significantly harder than standard structural metals. The reinforced Ø120 mm spindle and balanced dual 22 kW drive system are specifically calibrated to handle these hard materials without premature wear or accuracy drift, maintaining consistent stock removal rates across full production shifts.
4. Fast Changeover for Mixed Blade Production
Most blade manufacturers produce multiple sizes and specifications. The quick-change fixture system and wide parameter adjustment range support fast switching between different blade diameters and thicknesses. The 0.001 mm micro feed adjustment allows operators to fine-tune grinding parameters for each specific blade material and hardness grade, optimizing both processing speed and surface finish quality.

Frequently Asked Questions
Q: What blade materials can this double disc grinder process?
A: This machine is designed for circular cutting blades made from high-speed steel (HSS), alloy tool steel, stainless steel, cemented carbide and other common blade substrate materials. The adjustable feed parameters and independent wheel dressing system can be tuned to match different material hardness levels for optimal results.
Q: How does this blade-specific grinder differ from a standard general metal double disc grinder?
A: Three key differences: first, the extended 800 mm stroke accommodates larger-diameter blades and stacked batch processing; second, the spindle speed and power configuration are optimized for hard tool steel materials rather than standard structural metals; third, the precision level is calibrated to the tighter tolerances required for cutting blade pre-sharpening preparation.
Q: Can multiple blade sizes be processed on the same machine?
A: Yes. The wide diameter range of Ø80-450 mm and thickness range of 3-50 mm cover most standard industrial circular blade sizes. The quick-change fixture system supports relatively fast changeover between different blade specifications, making it suitable for manufacturers with mixed product ranges.
Q: What is stacked batch processing and how does it improve efficiency?
A: Stacked processing means clamping multiple blade blanks in sequence along the machines travel direction, so all blades pass through the grinding zone simultaneously in each cycle. This dramatically reduces per-piece processing time compared to grinding blades one at a time, while also improving batch-to-batch consistency since all blades receive identical grinding conditions.
Q: Does the machine require special factory installation preparation?
A: The 14,500 kg cast iron base provides excellent vibration damping. For most standard reinforced concrete factory floors, no special foundation construction is required. We provide foundation drawings and installation guidelines with each machine, and our service team can assist with on-site installation and commissioning if needed.
Q: What after-sales support is available for international customers?
A: We provide standard warranty coverage, international spare parts supply, remote technical consultation and optional on-site service visits. Our team has experience supporting blade manufacturers across multiple regions, and we can provide operator training either at our facility or on-site at your plant.
