Surface Grinding Machine CORMAK 400x1000 (406x1020)

Surface Grinding Machine 400x1000

The 400x1000 surface grinding machine is an advanced unit designed for precision grinding of flat surfaces in the machine-building industry. Equipped with automatic feeds for three axes and a digital readout, it ensures high machining accuracy while maintaining a robust construction. A key advantage of this magnetic surface grinder is its ability to handle heavy loads up to 600 kg, making it a reliable tool in demanding production applications.

Main advantages of the machine

The 400x1000 surface grinder stands out with parameters that directly translate into efficiency and durability in daily operation. Below are the key benefits resulting from its construction and technical specifications:

• Automatic feeds for three axes: Enable precise control of table movement, reducing operator error and increasing machining repeatability.
• Digital readout: Provides accurate position monitoring, minimising deviations and improving surface finish quality.
• Robust construction: Made from high-strength materials, ensuring stability when working with heavy parts up to 600 kg.
• High accuracy: With a grinding wheel speed of 1,450 rpm and precise vertical feeds from 0.005 mm, it achieves tolerances required in precision manufacturing.
• Efficient cooling system: The integrated cooling unit prevents overheating, extending tool life and improving surface finish quality.
• Energy-efficient motors: A 5.5 kW spindle motor provides optimal performance with low energy consumption, reducing operating costs.

Construction and technology

The 400x1000 surface grinding machine is based on a solid machine bed that ensures rigidity and minimises vibrations during operation. The spindle, operating at 1,450 rpm, is mounted in precision bearings, ensuring stable operation of the 350 x 40 x 127 mm grinding wheel. The hydraulic system handles longitudinal table feeds in the 7–23 m/min range, while automatic transverse and vertical feeds enable accurate movement control. The worktable measuring 406x1020 mm is equipped with an electromagnetic chuck for secure clamping. The integrated cooling system with a 0.14 kW pump efficiently dissipates heat. Drive motors, including a 2.2 kW oil pump motor and 1 kW vertical drive, are optimised for durability and low noise levels. The total machine weight of 4,000 kg highlights its stability in heavy industrial environments.

Precision and performance

Precision in the 400x1000 surface grinder results directly from its advanced feed and control mechanisms. Automatic intermittent transverse feed in the 0.1–8 mm range and vertical feed from 0.005 mm allow tolerances below 0.01 mm. Efficiency is increased by the maximum table travel of 450x1130 mm at transverse speeds up to 990 mm/min, enabling fast machining of large surfaces. The grinding wheel running at 1,450 rpm ensures even material removal, reducing tool wear and improving finish to Ra below 0.2 μm. The digital readout system eliminates manual errors and increases productivity. With a load capacity of 600 kg, the machine handles heavy parts without compromising precision.

Applications

The 400x1000 surface grinding machine is designed for metalworking facilities such as tool shops, machine factories and service centres. It is suitable for grinding flat surfaces of machine parts, dies, injection moulds and precision components with strict dimensional requirements. In B2B environments prioritising repeatability and efficiency, this magnetic surface grinder supports both series and single-piece production. It also enables regeneration of worn components in heavy industry, where the maximum distance from table to spindle centre of 570 mm allows machining of larger parts. Automatic feeds and digital readout reduce dependence on operator skill, making it an excellent choice for companies aiming to automate grinding processes.
