Machine tool castings It is a bed, column, beam, base it is reasonable structure, process performance is good, processing more convenient. Horizontal bed with a horizontal position of the knife to improve the movement of the tool holder precision, generally used for large CNC lathes or small precision CNC lathe layout.
Machine tool casting (bed casting) (large castings) using heat treatment process to eliminate the stress within the casting. Long-term use up more stable.
Standard: GB9439-88
Features: wear resistance, shock resistance is good, the process performance is good, gray cast iron carbon content is relatively high, close to the eutectic composition, so the melting point is relatively low, good fluidity, shrinkage is small, more suitable for structural casting complex or thin Wall castings. Graphite makes the cutting process easy to form chip breaking, gray cast iron cutting workability is higher than the steel. Casting early sand strength is high in favor of cast iron solidification process of graphitization expansion, effectively eliminate shrinkage, shrinkage defects , To achieve gray cast iron, ductile castor less riser, no riser casting.
The relationship between the strength and hardness of the machine tool castings (large castings): the correspondence between the hardness and the strength of the cast iron, and the empirical relationship is:
A. When O ≥ 196N / mm ㎡, HB = RH (fly 00 + 0 4380b) (B1).
B. When 0 ≥ 796N / mm ㎡, HB = RH (44 + O 7240b) (B2).
Casting Machine Tool Casting, Large Machine Tool Casting, Gantry Machine Casting, Vertical Machine Tool Casting, Large Casting. Machine Tool Casting Uses Die Casting Process. Machine Tool Casting Weight can reach 80 tons. Machine tool casting material gray iron 200, HT250, QT400, ZG450 and so on.

Machine tool bed castings As a large castings to be heat treated to improve their performance, improve the quality of internal heat treatment process is very important in mechanical manufacturing, compared with other processing technology, heat treatment does not change the shape of the workpiece and the overall chemical composition, by changing The internal quality of the workpiece to change the chemical composition of castings, to improve the use of performance.The purpose of tempering is to eliminate the internal stress quality.

I plant products are divided into two series:

(1) heavy machinery products: various types of new single and double column vertical lathe, test box, according to the needs of customers design and production. Heavy, large and medium-sized CNC machine tools, Cast iron machine sliding table; floor boring machine bed casting, bearing castings, railings base, with heavy iron, ductile castings, road squat, with heavy iron and other product design Processing and assembly.
(2) machine measuring tools: cast iron flat platform, the assembly plate, engraved flat plate, cast iron table, cast iron plate, pliers crossed platform, inspection plate, welding plate, riveting plate, marble flat, Box, aluminum-magnesium-foot, granite slab, granite measuring, flat feet, square feet, square feet, etc., machine horn (adjust horn, shock horn)

I produced the machine tool castings with advanced design, handsome in appearance, reliable performance, precision and stability, simple operation, easy maintenance, and other advantages, I plant will be high-quality products and good after-sales service return to our old and new customers, First, the principle of the supremacy of users, contract and keeping promises, the full implementation of tracking services.

1, manufacturers supply genuine: Main products casting machine, cast iron platform measuring, marble platform measuring tools and other products of professional producers, has a complete and scientific quality management system.

2, on the size: GB standard gauges I have a spot with the director, received orders, shipped within 48 hours; non-standard measuring tool can be customized, the production period is short, please rest assured purchase.

3, on the color: shops selling goods prices are excluding taxes and fees, for tax votes, please contact customer service.

4, on the customer service: If you can not get a timely response to the consultation, please contact the sales manager.

5, the establishment of product quality files, follow-up visit. Product life-long maintenance, only a simple charge of materials and labor costs, and trade-in.

6, actively cooperate with users to do a good job on-site operation and maintenance of products, providing free consulting services. May at any time to the user to provide the cost of factory products, spare parts and accessories.

7, splicing platform or multiple devices installation, commissioning, on-site technical services, led by technical experts personally on-site service to solve various difficult problems.

8, on the delivery: simple wooden packaging products, non-customized products, the following single-piece products 50kg ordinary courier, usually within 72 hours of arrival; single 50kg or more products using logistics and distribution, your city direct line priority , Remote or small towns are Qiyun logistics Peihuo, the general arrival time of 4-7 days. Delivery costs to the actual logistics company quoted price, the goods sold by shops are not included in the transport costs. If you special requirements Express , Air and rail freight to be self-pay freight.

Botou Yongjun Gauge Machinery Factory is located in Botou City, south of Tianjin. Since ancient times, it enjoys the reputation of 'Casting Country' in China. It has a long history, advanced technology, perfect management and developed casting industry. With the new structure, new technology, new technology and high-quality casting materials, the company's technology and technical equipment: the existing medium-frequency electric furnace 8 tons, 10 The company strictly control the purchase of raw materials, all based on national standards of production, the technical indicators have reached the national Standard, the products sell well all over the country are exported to foreign countries, and built a casting workshop, machining workshop, scraping workshop, assembly workshop tempered kiln, laboratory, laboratory, production of products have been tested: In the thermometer temperature, the finished product for ultrasonic testing and hardness testing, so that the product even more than the appearance of Gengrang customers rest assured that satisfaction.
