Core Machine Advantages
1. Cost-Effective Versatility
Workshops processing a mix of different metal parts no longer need multiple dedicated grinding machines. This general metal model handles carbon steel, alloy steel, stainless steel and non-ferrous metal workpieces with adjustable parameters, reducing overall equipment investment and saving valuable workshop floor space.
2. Single-Setup Double-Sided Efficiency
Traditional single-sided grinding requires two separate clamping operations to finish both faces of a workpiece, introducing alignment errors and extra labor time. This double disc design machines both surfaces simultaneously in one setup, cutting cycle time roughly in half while improving parallelism consistency across production batches.
3. Stable Long-Run Precision
The 12-ton solid cast iron base absorbs operational vibration effectively, preventing the geometric drift that plagues lighter-frame grinders during extended production runs. Combined with the balanced dual-motor drive system, it maintains consistent flatness and parallelism tolerance shift after shift, reducing scrap rates and rework costs.
4. Low Installation & Maintenance Barrier
Unlike heavy industrial grinders that require custom reinforced concrete foundations, this machine operates stably on standard factory flooring. Its straightforward mechanical design also simplifies routine maintenance, minimizing downtime and keeping long-term operating costs predictable for small and mid-size manufacturing facilities.
Functional Highlights
Adjustable Speed Control System
Two independent speed adjustment systems give operators full control over the grinding process. The main feed speed ranges from 2 to 12 m/min - higher settings for rapid rough stock removal, lower speeds for fine finishing work. The wheel dresser travel speed adjusts from 0.5 to 1.5 m/min, allowing precise control over abrasive wheel conditioning to match different material hardness levels.
Balanced Dual Drive Configuration
Paired 22 kW grinding head motors deliver matched cutting torque for both grinding discs. The symmetric power layout ensures even material removal across both workpiece surfaces, preventing one-sided over-grinding and maintaining consistent thickness from part to part throughout each production batch.
Vertical Stroke & Fixture Flexibility
The 130 mm vertical grinding head stroke provides ample clearance for mounting different fixture types. Whether processing thin 1.5 mm sealing washers or 60 mm thick bearing rings, operators can quickly swap fixture setups without major machine reconfiguration, supporting fast changeover between different production orders.
Industry Applications
This general metal double disc grinder is widely deployed across multiple manufacturing sectors:
- General Metal Fabrication - Washers, spacers, flanges and custom circular metal components
- Automotive Component Supply - Bearing races, valve discs, sealing rings and transmission parts
- Hardware Manufacturing - Precision washers, fastener components and small metal hardware
- Hydraulic & Pneumatic Parts - Valve plates, sealing discs and pressure component blanks
- Contract Machining Shops - Mixed-batch precision grinding for diverse client orders
Typical workpieces include steel washers, bearing inner and outer races, metal sealing rings, flange blanks, valve discs, pump components and various standard circular metal parts requiring parallel flat surfaces.

Frequently Asked Questions
Q: Can it handle both thin washers and thick bearing parts in the same production day?
A: Yes. The wide thickness range of 1.5-60 mm and 130 mm vertical stroke support flexible switching between ultra-thin and medium-thickness workpieces. Fixture changeovers are straightforward, making it well-suited for mixed-batch production environments.
Q: How does double disc grinding compare to single-sided grinding in terms of efficiency?
A: Double disc grinding typically cuts processing time by approximately 40-50% compared to single-sided grinding, since both faces are finished in one pass. It also delivers better parallelism consistency because there is no re-clamping step that introduces alignment errors.
Q: Does the machine require special factory foundation preparation?
A: No. The 12-ton cast iron base provides sufficient vibration damping for standard operation. Most workshops can install the machine directly on standard reinforced concrete factory floors without custom foundation construction. We do provide foundation drawings for reference if needed.
Q: What after-sales support is included with the machine?
A: We provide a standard warranty period, spare parts supply, technical consultation support and optional on-site maintenance services. Our international service team can assist with installation guidance, operator training and troubleshooting for customers worldwide.
Q: Can the machine be upgraded with CNC controls later?
A: Yes, we offer CNC control upgrade options both at time of purchase and as a field upgrade. The CNC version supports multiple grinding recipe storage, automatic parameter adjustment and digital precision monitoring for more sophisticated production requirements.
