Surface Grinding Machine 400x800

The Surface Grinding Machine 400x800 is an advanced device designed for precision grinding of flat surfaces in an industrial environment. Equipped with automatic feeds for three axes and a 406x813 mm magnetic table, it ensures high accuracy and reliability. Its solid structure and ability to handle loads up to 500 kg make it an ideal choice for demanding production applications.

Main advantages of the machine

The Surface Grinding Machine 400x800 has been designed for maximum efficiency and precision in metalworking. With the use of modern technologies and robust components, this machine stands out among other surface grinders available on the market. Below are the key benefits resulting from its technical specifications and design, providing an advantage in production environments:

• Automatic feeds for three axes: Allow precise control of the longitudinal, transverse and vertical table movements, eliminating operator errors and improving repeatability.
• Digital readout: Ensures accurate monitoring of table position, minimising deviations and improving surface finish quality to a level below Ra 0.2 μm.
• Solid bed structure: Made of high-strength materials, guarantees stability during machining of heavy workpieces up to 500 kg, reducing vibration and increasing the machine’s durability.
• High precision: With vertical feeds from 0.005 mm and a grinding wheel speed of 1,450 rpm, the machine achieves tolerances below 0.01 mm, meeting the requirements of precision manufacturing.
• Efficient cooling system: The integrated cooling system with a 0.125 kW pump prevents overheating of workpieces and tools, extending their service life and improving surface quality.
• Optimal energy efficiency: The 5.5 kW spindle motor and energy-optimised drives provide high performance with reduced operating costs.
• 406x813 mm magnetic table: Allows quick and safe clamping of workpieces, improving work efficiency and operator safety.

Construction and technology

The Surface Grinding Machine 400x800 features an advanced structure that combines durability with functionality. The machine bed, made of high-quality cast iron, ensures rigidity and minimises vibrations, which is crucial when machining heavy components. The spindle, running at 1,450 rpm and mounted in precision bearings, works with a 350 x 40 x 127 mm grinding wheel, guaranteeing stable and uniform machining. The hydraulic system handles longitudinal table feeds in the range of 7–25 m/min, while automatic cross and vertical feeds allow precise movement control with an accuracy of 0.005 mm. The magnetic table measuring 406x813 mm provides secure workpiece clamping, speeding up setup. The integrated cooling system with a 0.125 kW pump effectively removes heat, preventing thermal deformation and extending tool life. The drive motors, including a 2.2 kW oil pump motor and a 0.5 kW vertical feed motor, are optimised for energy efficiency and low noise. The total weight of 3,500 kg highlights the stability and reliability of the machine in intensive industrial environments.

Precision and performance

The Surface Grinding Machine 400x800 delivers exceptional precision thanks to advanced feed and control mechanisms. Automatic intermittent feed in the range of 0.1–8 mm and vertical feed from 0.005 mm allow tolerances below 0.01 mm, essential in the production of precision components. The maximum table feed of 450x910 mm at a crossfeed speed of up to 990 mm/min enables fast machining of large surfaces without losing accuracy. The grinding wheel operating at 1,450 rpm ensures even material removal, minimising tool wear and improving surface finish quality. The three-axis digital readout system eliminates manual errors, shortens setup times, and increases production throughput. Compared to other surface grinders, this model stands out with a 500 kg load capacity, enabling machining of heavier parts without compromising precision. The energy efficiency of the motors and solid structure minimise downtime, making this magnetic surface grinder an effective tool for production process optimisation.

Applications

The Surface Grinding Machine 400x800 is intended for manufacturing plants specialising in metalworking, such as tool workshops, machine component factories, and service centres. It is perfect for grinding flat surfaces of components such as dies, injection moulds, base plates, or precision parts requiring high dimensional accuracy. In B2B environments where repeatability and efficiency are essential, this magnetic surface grinder supports both serial and single-piece production, handling materials such as steel, cast iron, and aluminium alloys. It is also suitable for regenerating worn components in heavy industry, where the maximum distance from table to spindle of 580 mm allows machining larger workpieces. The machine is particularly recommended for companies aiming to automate grinding processes, as automatic feeds and digital readout reduce operator dependency.
