Material of main body Gray HT300, strength, and guide high hardness (52HRC), gravity can be cutting, guide rail mill once grinding process for success, with good guiding accuracy;

2.Meet the strength of casting characteristics of sliding structure, Thin-walled bar, good rigidity, strong resistance to deformation, each casting after aging treatment guide accuracy remained stable;

3. high precision double nut ball screw transmission, large carrying capacity, good dynamic performance, high accuracy;

4. Skate contact with the rail surface uniform laminating, aligning the rail wear, is not easy to pull, advantages:

① dynamic coefficient of friction small, flexible sliding and lubricating properties, low speed without crawling;

Secondly, good wear resistance, long service life, maintenance time, and ease of maintenance.

5. reasonable tank, full of oil, as long as the oil into the lubrication of sliding contact surface and avoid friction, minimizes contact surface wear, maintain accuracy for a long time;

6. the scrapings of the closed device and dust cover, preventing the iron dust into the sliding contact surface of rail damage, which affects the service life.

Machine tool castings HT300 delicate selection of high quality gray iron, precise ratio high tensile bending strength, make your purchase worry-free. International heat treatment process, to minimize the stress and deformation of casting. Use for a long time tend to be more stable and large machines for processing, milling and boring can be. All processing of the factory 3.2*16 metre Planer, large bed casting 16-meter bed all the straightness and final Machining accuracy.

The advantages of high quality machine tool castings:

1, good rigidity of resin-bonded sand, pouring sand in the early high strength, this conditional use graphite of cast iron solidification process of expansion, effectively eliminate shrinkage shrinkage, achieved grey cast iron, less ductile cast iron riser riser-free casting.

2, used in full mold casting production of polystyrene foam plastic, resin sand molding applications pyran. When the molten metal poured into the mold, and foam quickly gasification under high wild metal, burn and the husband, instead occupied by Wang plastic bubble of molten metal, solidification and cooling of the same shape full mold casting.

3, in contrast, lost foam casting for the production of single parts or small quantities of automotive panels, bed and other large molds, such as traditional sand has a great advantage, it not only eliminates the high cost of wood, and easy, shorten the production cycle, improving production efficiency, with high dimensional accuracy, machining small, good surface quality and other advantages.

Machine tool castings features:

(1) EPC casting good wearability and weakening. As in cast iron with graphite to lubricate and oil storage, good resistance to abrasion. Similarly, due to a weakening of graphite is better than that of steel.

(2)Process performance. Because of the high carbon content in cast iron, close to the eutectic composition, low melting point, good liquidity, shrinkage, so suitable for casting complex structures or thin-walled castings. In addition, because of easy to form graphite machining chip breaker, machinability is better than that of grey cast iron and steel.

Botou Yongjun measuring machinery company is located is known as ' China town ' of botou city, North of Beijing and Tianjin, East of the Bohai Sea, 104, 106 national highway, Beijing-Shanghai Expressway, Beijing-Shanghai Railway runs through the whole territory, the geographical position is superior, the transportation is convenient. Our company mainly produces marble platform, cast iron platform shaped castings, machine tool castings, cast iron slide units, square box
