Centerless Grinding Machine GD-12 CNC

GD-12 CNC Centerless Grinder

A professional centerless grinding machine designed for high-precision part machining with minimal runout and superior surface finish, ideal for high-volume production in modern manufacturing facilities.

1. Precision and Ultra-Rigid Construction

Monolithic Base: The machine bed and main components are manufactured from high-grade cast iron using a one-piece casting process.

High Precision: All base components are machined in a single setup on precision equipment from leading global brands (YASDA, MITSUI SEIKI, TOSHIBA, ELB). This ensures exceptional dimensional accuracy.

2. High-Tech and Wear-Resistant Spindle Assembly

Original Taiwanese Spindle: Manufactured from SNCM-21H alloy steel.

Multi-Stage Treatment: Surface hardness exceeds 62 HRC, and the depth of the hardened layer is over 1.5 mm.

Hydrodynamic Oil Film Technology: Utilizes a dynamic hydrodynamic oil film spindle, ensuring exceptional running smoothness, vibration damping, and the highest grinding accuracy.

3. Ultra-Precise Adjustment and Feed System

High-Precision Increment: The fine adjustment scale of the regulating wheel and the feed leadscrew under the worktable have a resolution of just 0.001 mm, allowing for meticulous adjustment of the material removal process.

Flexible Geometry: The regulating wheel can be tilted in the range of +5° to -3° and swiveled by ±6°, ensuring optimal setup for various types of centerless grinding (through-feed and in-feed).

4. Optimal Technical Specifications for a Wide Range of Applications

Versatility: Capable of machining workpieces with diameters from 0.5 to 40 mm, making it ideal for the production of small and medium-sized parts (shafts, axles, pins, etc.).

Powerful Drives: The grinding wheel (305 mm) is driven by a 7.5 HP motor (1950 rpm), while the regulating wheel (205 mm) is driven by a 2.0 kW motor with stepless speed adjustment from 0 to 300 rpm.

5. Reliability and Manufacturer's Reputation

Extensive Experience: Over 15 years of successful operation in the design, R&D, and production of grinding equipment.

Large-Scale Production: Own production area of over 6,000 sq. meters and a complete range of machine models with extensive functionality.

Quality Guarantee: Production is certified to the international quality management system standard.
