Delta Elle LC400
A rotary table grinding machine for high-precision leveling of discs, flanges, and other circular metal parts requiring perfect flatness.
- Maximum Structural Rigidity: The bed and main machine components are cast from certified high-quality cast iron with increased wall thickness and special reinforcing ribs, guaranteeing absolute structural stability and zero vibration during operation.
- Proprietary Precision Spindle: The grinding head is equipped with a proprietary Delta electro-spindle, built with high-precision bearings and subjected to mandatory dynamic balancing using modern electronic equipment.
- Ideal Geometry and Micrometric Precision: Special adjustment devices ensure strict perpendicularity of the head relative to the worktable. Rapid vertical feed is provided for fast operation, while a convenient detent dial allows easy micrometric fine-tuning down to 0.01 mm precision.
- Versatile Configurations for Any Task: Within a single series, the brand offers a choice of five models with three types of worktables — fixed, rotating round, or a unique synchronized tilting table.
- Decades of Proven Quality: Since manufacturing its first vertical machines in 1955, Delta has delivered over 20,000 equipment units worldwide, earning a reputation as a market leader and winning gold medals for technological progress.
