1. Product Overview: Hand-Operated Surface Grinder Lineup
Our hand-operated surface grinders (618 / 450 series) are engineered for stable performance, smooth operation, and lightweight handling. Built with a reinforced, widened, and thickened machine frame, these grinders deliver consistent reliability and precise results for small-to-medium workshop grinding tasks.
Key common features across all models include:
- V3 low-vibration original Taiwanese spindle unit for quiet, stable operation
- Standard two-axis linear scale with digital readout for precise positioning
- Grinding accuracy controlled to <0.002mm for high-precision finishing
- Ergonomic design for smooth, fatigue-free manual operation
The compact PSG-618M is ideal for small-scale precision grinding applications.
- Drive system: Left/right axes driven by Japanese imported steel wire ropes for long-lasting durability and smooth motion
- Best suited for light-duty, high-precision tasks in tool rooms and small workshops
- Compact footprint with full precision grinding capabilities
The PSG-450AS is built for larger workpieces with enhanced operational efficiency.
- Drive system: Left/right axes driven by synchronous belts for lighter, quieter operation
- Optimized for medium-sized workpieces while maintaining the same <0.002mm accuracy
- Combines stable grinding performance with reduced operator effort
2.Main Components
1. Precision Ball Screw Assembly
Every grinder is equipped with P3-grade high-precision ball screws for
exceptional motion control. With a low friction coefficient of 0.002–0.005 and over 90% transmission efficiency, these screws minimize heat buildup, reduce wear, and eliminate backlash. Adjustable preload ensures consistent positioning accuracy, converting rotary motion into smooth linear feed to deliver the micron-level precision required for critical grinding operations.
2. Heavy-Duty Spindle Performance
Engineered for industrial-grade durability, each spindle is fitted with Japanese NSK CP4 precision angular contact ball bearings. The spindle runout is controlled to within 0.002mm, guaranteeing stable, vibration-free cutting even under heavy loads. This robust spindle design ensures consistent surface finishes and reliable performance for more than 10 years of continuous use.
3. Rigid HT300 Cast Iron Base
The machine bed, worktable, and key structural components are cast from high-grade HT300 grey cast iron. After high-temperature tempering and more than 6 months of natural aging, internal stresses are fully eliminated, preventing long-term deformation. The rigid, vibration-dampening structure provides a stable foundation for high-precision grinding, maintaining dimensional accuracy over decades of operation.
4. High-Response Servo System
Our grinders use top-tier control systems from Siemens, Mitsubishi, and Delta, paired with precision servo drives. The closed-loop servo control delivers ultra-fine feed resolution down to 0.001mm, ensuring precise, repeatable positioning for every cut. With fast response and smooth acceleration/deceleration, the system supports both high-speed rough grinding and ultra-precise finishing operations.
5. Hand-Scraped Guideways for Superior Stability
To achieve the highest level of surface contact and oil retention, guideways are hand-scraped by experienced technicians with over 10 years of expertise. Finished to 10–12 contact points per square centimeter, the guideways are then lined with imported Teflon to reduce friction and wear. This traditional craftsmanship ensures smooth, stick-slip-free movement and long-term geometric accuracy.
6. High-Efficiency Electromagnetic Chuck
Equipped with a high-performance electromagnetic chuck featuring steel plate bonding technology and full copper coils, our grinders deliver strong, evenly distributed magnetic force up to 16 kg/cm². The chuck is adjustable for different workpiece sizes, supports continuous operation for over 20 hours, and features automatic auxiliary positioning. It can clamp or release workpieces in just 0.3 seconds, drastically improving production efficiency in batch grinding applications.
