Precision Centerless Grinder

Suitable For: Smooth shafts and long rod-shaped parts (such as piston rods, steering shafts, needle rollers).

Core Advantages: Utilizes wide-wheel, one-pass grinding technology for high-efficiency machining and perfect cylindricity.

• WT-Standard: Suitable for shafts of standard length (≤2m), offering excellent value.

• WT-Wide: Equipped with 400mm-600mm ultra-wide grinding wheels, specifically designed for ultra-long shafts (≤4m), completely eliminating concavity.

• WT-HighSpeed: Optimized guide wheel speed and feed mechanism, designed for high-volume production of small-diameter parts (such as pins), increasing cycle time by 50%.

Suitable For: Parts with steps, tapers, spherical surfaces, or complex contours (e.g., camshaft journals, bearing races).

Core Advantages: Utilizes a narrower grinding wheel width, achieving one-time forming of complex contours through radial feed and CNC dressing.

• IF-Basic: Suitable for simple stepped shafts, easy to operate.

• IF-CNC: Multi-axis linkage (X/Z/C axes), combined with diamond roller dressing, capable of grinding complex curved contours.

• IF-Multi: Supports multiple grinding wheel combinations or double-plate structures, completing grinding of multiple sections with different diameters in a single setup.

Suitable For: Parts requiring high precision and with complex processes.

Core Advantages: Integrates multiple processes, effectively reducing clamping times and improving positional accuracy.

• CG-Dual (Dual Grinding Wheel Series): The front grinding wheel rough grinds to remove excess material, while the rear grinding wheel finishes the surface; a single machine completes both rough and finish machining.

• CG-EndFace (External Diameter & End Face Composite): Integrates an end face grinding unit while centerlessly grinding the external diameter, solving the perpendicularity problem.

Features: Manual loading and unloading or simple vibratory feeder; PLC-controlled grinding cycle.

Applications: Small batch production of various varieties; R&D and trial production; repair workshops.

Features: Integrated gravity feeder, stepper feeder, or simple robotic arm for continuous automatic feeding.

Applications: Medium batch production, reducing worker workload.

Specifically Designed For: Ultra-fine shafts with diameters of 0.1mm - 5mm (e.g., medical guidewires, watch shafts).

Configuration: High-magnification microscopic vision system, micro-feed mechanism, vibration-resistant foundation.

Advantages: Roundness can reach sub-micron level (<0.5μm).

Designed For: Large rolls and paper rolls with diameter > 200mm and length > 3m.

Configuration: High-torque guide wheel drive, heavy-duty mineral casting bed, double support plate.

Advantages: High rigidity, maintaining high precision under heavy loads.

Designed For: Aerospace, measuring tools, and other parts extremely sensitive to thermal deformation.

Configuration: Full-machine constant-temperature cooling system (oil/water/air), thermo-symmetrical structural design.

Advantages: Precision virtually non-drifting within ±5℃ ambient temperature fluctuations.

Technical Support: Equipped with 300mm-600mm ultra-wide grinding wheels and extended carbide support plates.

Customer Value: Provides an ultra-long continuous support reference, effectively suppressing elastic deformation of slender shafts. Cylindricity can be easily controlled within 0.002mm/500mm, completely eliminating the problem of center concavity or tapered errors in the workpiece.

Technical Support: High-power servo guide wheel drive & large-angle tilting mechanism & high-speed through grinding process.

Customer Value: Enables "one-pass, finished delivery" for long shaft parts. Compared to traditional reciprocating grinding, the cycle time per piece is shortened to the second level, significantly reducing the manufacturing cost per piece and meeting the needs of large-scale delivery of millions of units.

Technical Support: High-rigidity mineral casting bed & hydrostatic spindle & full-area powerful cooling system.

Customer Value: Extremely high system damping eliminates all chatter and spiral marks. Surface roughness consistently reaches Ra 0.1μm - 0.2μm, eliminating the need for subsequent polishing and directly meeting the requirements of hydraulic sealing and high-precision fit.
