circular grinding machine ШУ321 - Bulgaria

Universal cylindrical grinding machines with hydro mechanical drive in Bulgaria feature high reliability, easy operation and build quality of the machine. The price round grinding machine Bulgarian production is much lower than European counterparts.

Also this equipment you can install additional devices and nodes that can extend the capabilities of the machine. For example, internal grinding head for grinding the internal surfaces of the parts, this the fixture installs on circular grinding machine ШУ321 and gives the ability to process complex parts in a single setup. The machine is equipped with various auxiliary devices: a device for balancing round, fixture for grinding wheel, open and closed lunettes, kit leashes, etc.

Universal cylindrical grinding machine mod. SHU 321 is designed to handle exterior front and inner surfaces of parts with cylindrical and a conical shape by grinding.

When grinding the outer surfaces of the part can be fixed in the centers, or clamped in the Chuck. When sanding the internal surfaces of the clamp the details are only in the cartridge.

The machine spindle is equipped with a special hydraulic supports, allowing you to achieve a roughness of the processed surface of 0.4 mm and tolerances, deviations from the roundness of the treated surface in the transverse the cross section in the range of 0.0025 mm cylindricity – within 0.01 mm.

Cylindrical grinding machine equipped with a hydraulic system supply control that enables looping surfaces minimum cost of the basic and auxiliary process time.

Cylindrical grinding machine has a convenient system of adjustment and management enabling the changeover between the same type of detail and also between settings for grinding outer and inner surfaces with minimal time spent.
