Main advantages of the machine

The Surface Grinding Machine 400x800 has been designed for maximum efficiency and precision in metalworking, offering users advanced technological solutions that distinguish it among surface grinders. Its design and technical parameters translate into measurable benefits in production environments where repeatability, durability and high surface finish quality are crucial. Below are the key advantages that make it an indispensable tool in professional workshops and factories:

• Automatic feeds for three axes: Provide precise control of longitudinal, cross and vertical table movement, minimising operator errors and improving process repeatability.
• Digital readout: Enables accurate table position monitoring, achieving surface finish roughness below Ra 0.2 μm and minimising dimensional deviations.
• Solid bed construction: Made of high-quality cast iron, guarantees stability during machining of workpieces up to 500 kg, reducing vibrations and ensuring long-term reliability.
• High machining 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 demands of precision production.
• Efficient cooling system: The integrated cooling system with a 0.125 kW pump prevents overheating of workpieces and tools, extending their lifespan and improving surface quality.
• 400x800 mm magnetic table: Allows fast and secure workpiece clamping, increasing work efficiency and operator safety.
• Optimal energy efficiency: The 5.5 kW spindle motor and energy-optimised drives provide high performance with reduced operational costs.

Construction and technology

The Surface Grinding Machine 400x800 features an advanced design that combines durability with functionality. The machine bed, made of high-quality cast iron, ensures rigidity and minimises vibration – crucial when machining heavy components. The spindle, operating at 1,450 rpm and mounted in precision bearings, works with a 350 x 40 x 127 mm grinding wheel, providing 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 enable precise motion control with 0.005 mm accuracy. The 400x800 mm magnetic table ensures reliable workpiece clamping, speeding up setup time. The integrated cooling system with a 0.125 kW pump efficiently removes heat, preventing thermal deformation and extending tool life. Drive motors, including a 2.2 kW oil pump motor and 0.5 kW vertical drive motor, are optimised for energy efficiency and low noise levels. The overall construction weighing 3,500 kg highlights the machine’s stability and reliability in demanding industrial environments.

Precision and performance

The Surface Grinding Machine 400x800 offers outstanding 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 for precision part production. The maximum table feed of 450x910 mm with a crossfeed speed of up to 990 mm/min enables fast machining of large surfaces without compromising accuracy. The grinding wheel, rotating at 1,450 rpm, ensures uniform material removal, reducing tool wear and improving surface finish quality. The three-axis digital readout system eliminates manual errors, shortens setup time, and increases productivity in production cycles. Compared to other surface grinders, this model stands out with a 500 kg load capacity, allowing the machining of heavier parts without sacrificing accuracy. The machine’s energy-efficient motors and robust design minimise downtime, making this magnetic surface grinder an effective tool for optimising production processes.

Applications

The Surface Grinding Machine 400x800 is intended for production facilities specialising in metal processing, such as tool workshops, machine component factories, and service centres. It is ideal for grinding flat surfaces of elements such as dies, injection moulds, base plates, or precision parts requiring high dimensional accuracy. In B2B environments where repeatability and efficiency are crucial, this magnetic surface grinder supports both series and single-piece production, handling materials like steel, cast iron, and aluminium alloys. It is also suitable for reconditioning worn components in heavy industry, where the maximum distance from table to spindle of 580 mm enables machining of larger parts. The machine is particularly recommended for companies aiming to automate grinding processes, with automatic feeds and digital readout reducing operator-dependence.
