Main advantages of the machine

The 400x1000 surface grinding machine stands out with advanced technical parameters that provide unmatched precision and efficiency in metalworking. Designed for intensive industrial environments, it offers users reliability, durability and optimisation of operating costs. Its construction and applied technologies, such as automatic feeds and digital position readout, minimise errors and increase the efficiency of production processes. Below are the key benefits that make this magnetic surface grinder a leader in its class:

• Automatic feeds for three axes: They enable precise control of longitudinal, cross and vertical table movement, eliminating operator errors and ensuring high machining repeatability.
• Digital readout: It provides accurate monitoring of table position, enabling a surface finish with roughness below Ra 0.2 μm and minimising dimensional deviations.
• Robust bed construction: Made of high-quality cast iron, it guarantees stability during machining of heavy workpieces weighing up to 600 kg, reducing vibration and increasing machine durability.
• High machining precision: Thanks to vertical feeds from 0.005 mm and a grinding wheel speed of 1450 rpm, the machine achieves tolerances below 0.01 mm, meeting the requirements of precision production.
• Efficient cooling system: The integrated cooling system with a 0.14kW pump prevents overheating of workpieces and tools, extending their service life and improving the quality of the ground surface.
• 406x1020 mm electromagnetic table: It allows quick and secure clamping of workpieces, increasing work efficiency and operator safety.
• Optimal energy efficiency: The 5.5kW spindle motor and drives with optimised energy consumption ensure high performance with reduced operating costs.

Construction and technology

The 400x1000 surface grinding machine features a robust construction that combines durability with advanced technology. The machine bed, made of high-quality cast iron, ensures rigidity and minimises vibration during machining, which is crucial for precision grinding. The spindle with a speed of 1450 rpm, mounted in precision bearings, works with a grinding wheel measuring 350 x 40 x 127 mm, guaranteeing stable and even machining. The hydraulic system handles longitudinal table feeds in the range of 7~23 m/min, while automatic cross and vertical feeds enable precise motion control with an accuracy of up to 0.005 mm. The electromagnetic table measuring 406x1020 mm ensures secure clamping of workpieces, speeding up the preparation process for machining. The integrated cooling system with a 0.14kW pump effectively dissipates heat, preventing thermal deformation and extending tool life. The drive motors, including the 2.2kW oil pump motor and 1kW vertical drive, are optimised for energy efficiency and low noise levels. The entire construction, weighing 4000 kg, highlights the machine's stability and reliability in intensive industrial environments.

Precision and operating efficiency

The 400x1000 surface grinding machine offers exceptional precision thanks to advanced feed and control mechanisms. The automatic intermittent feed in the range of 0.1~8 mm and vertical feed from 0.005 mm allow tolerances below 0.01 mm to be achieved, which is crucial in the production of precision components. The maximum table travel of 450x1100 mm with a cross speed of up to 990 mm/min enables fast machining of large surfaces without loss of accuracy. The grinding wheel with a speed of 1450 rpm ensures even material removal, minimising tool wear and improving surface finish quality. The digital readout system for three axes eliminates manual errors, reducing machine setting time and increasing throughput in production cycles. Compared to other surface grinding machines, this model stands out with a high load capacity of 600 kg, enabling the machining of heavier workpieces without compromising precision. The energy efficiency of the motors and the robust construction minimise downtime, making this magnetic surface grinder an effective tool for optimising production processes.

Application

The 400x1000 surface grinding machine is intended for production plants specialising in metalworking, such as toolrooms, machinery factories and service centres. It is ideal 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 a priority, this magnetic surface grinder supports both batch and one-off production, handling materials such as steel, cast iron or aluminium alloys. Its application also includes the regeneration of worn components in heavy industry, where the maximum distance from the table surface to the spindle centre of 570 mm enables the machining of larger workpieces. The machine is particularly recommended for companies aiming to automate grinding processes, thanks to automatic feeds and digital readout, which reduce dependence on operator skill.
