Product Overview
The CNC-controlled Beam Guideway Grinders (MLK Series) are heavy-duty, high-precision gantry-type grinding machines engineered for large-scale and high-requirement processing. Featuring a stepped gantry rigid frame (composed of bed, column, and crossbeam), these machines deliver exceptional dynamic stiffness and stability during high-load operations. Designed for grinding planes, rail surfaces, and large workpieces made of steel, cast iron, and non-ferrous metals, the MLK Series is a game-changer for industries like machine tool manufacturing, mold production, and heavy machinery fabrication. With multiple models (from MLK2010A to MLK8020A), it offers flexible solutions for different workpiece sizes and processing demands.
Key Features
Stepped Gantry Rigid Frame
Integral structure of bed, column, and crossbeam forms a robust rigid frame, ensuring sufficient dynamic stiffness during worktable and carriage movement—critical for heavy-duty grinding.
Advanced Drive & Control System
Hydraulic-driven worktable with automatic speed control (5~25 m/min) for smooth and consistent longitudinal movement.
Carriage horizontal movement and slide vertical movement controlled by precision servo systems, supporting free CNC selection for high precision.
Minimum vertical feed of 0.005 mm, achieving ultra-precise grinding results.
Flexible Grinding Head Design
Vertical grinding head can rotate ±60° freely, adapting to bevel, inclined plane, and complex surface grinding requirements.
Large grinding wheel size (φ500×75×φ203 or φ500×100×φ203) for efficient material removal and prolonged service life.
Heavy-Duty Performance
Worktable maximum load ranges from 4000 kg (MLK2010A) to 30000 kg (MLK8020A), capable of handling large and heavy workpieces.
High motor power (1522 kw) and total electrical capacity (3550 kw) support continuous high-efficiency production.
Safety & Durability
Comprehensive safety control system protects operators and equipment.
Rugged construction and high-quality components ensure long-term reliable operation, reducing maintenance costs.
