The Ralli Wolf GL3 Lathe Grinder is a dedicated tool-post grinder engineered for high-precision cylindrical internal and external grinding operations directly on workshop lathes. Powered by an efficient 400W full load motor, this machine enables machine shops to achieve tight dimensional tolerances and ultra-smooth surface finishes on turned components without removing them from the lathe chuck.

Built for maximum operational versatility, the GL3 operates at two distinct spindle speeds: 8,000 RPM for external grinding and a high-speed 19,000 RPM for deep internal grinding. With a rigid 9.8 kg body designed to mount securely onto the compound slide of standard lathes, it dampens operational chatter to ensure exceptional accuracy on hardened shafts, bushings, bores, and tool bits.

Key Features

• Dedicated Tool-Post Grinder: Mounts directly to the compound rest or tool post of standard metal lathes for seamless turning-to-grinding conversion.
• Dual-Function Grinding: Engineered for both external OD cylindrical finishing and deep internal ID bore grinding in machine shops.
• High-Speed Spindle Operation: Runs at 8,000 RPM for external grinding wheels and up to 19,000 RPM for high-precision internal grinding quills.
• Reliable 400W Motor: Delivers consistent, smooth rotary power under full continuous load for steady material removal.
• Rigid Machine-Shop Construction: Heavy 9.8 kg cast structure eliminates chatter and absorbs vibrations to maintain micro-inch surface finishes.
• Standard Wheel Capacity: Accommodates Ø75 x 13 x Ø19 mm grinding wheels for diverse precision finishing tasks.
