Bridge type five-axis five-linkage machine center

Defeng DFW3020 five-axis swing gantry machine tool is a domestic leading swing five-axis machine tool with long-term technology accumulation of Defeng Company. Defeng five-axis gantry machine tool, in the collocation of the main accessories, completely use imported accessories. The safety, stability and accuracy of five-axis machine tools are guaranteed by high-quality accessories regardless of cost. As standard, each is equipped with Heidenhain 640 or SIEMENS 840D-SL system, Italian HSD five-axis head, and Japanese THK screw guide rail. At present, the trial cutting of international standard S parts can reach within plus or minus 3 wires. The technical requirements are based on the imported machine tools. This machine tool is a magic weapon for processing aircraft, military industry, high-precision molds and other parts.

Normal T Horizontal Machining Center MHB Series

Defeng horizontal machining center is a high-precision and high-efficiency machine tool equipment, which is widely used in mechanical engineering, automotive, aerospace, mold manufacturing and other fields. Its main features include: 1. High precision and stability: The horizontal machining center adopts integral T-type casting bed and gantry column structure, which has high rigidity and long-term stable precision. The main shaft adopts three-point support to ensure high rigidity and high rotation accuracy. In addition, the Y-axis double guide system and the three-axis guide rail pair adopt the quenched and ground rectangular guide rail, which further improves the accuracy and stability of the machine tool. 2. Horizontal machining centers are suitable for a variety of machining tasks, including milling, drilling, reaming, boring and tapping. It can complete the processing of multiple surfaces by one clamping, effectively reduce the cumulative error caused by multiple clamping, improve the processing accuracy and efficiency, and is widely used in many fields such as automobile, aerospace, mold manufacturing, medical equipment and so on.

Crane type five-axis machining center MCB series

1. Structural design advantages: -High rigidity and stability: The crane structure is usually made of solid frame and high-quality materials, such as high-strength cast iron, etc. The residual stress is eliminated by reasonable heat treatment process, and sufficient stiffening plates are arranged. This kind of structural design enables the machine tool to withstand large cutting force and impact force in the process of machining, and ensures the accuracy and stability of machining. Like some large complex parts processing, the rigidity and stability of the machine tool are required to be high, and the five-axis machining center of the crane type can well meet this demand. 2. Sports performance advantages: -High-precision motion control: The five-axis linkage motion control system can realize the coordinated motion of five coordinate axes, so that the tool can process the workpiece at any angle and direction. This high-precision motion control can ensure the machining accuracy of complex curved surfaces and special-shaped parts, such as parts in the field of aerospace, automotive molds, etc., which require very high machining accuracy, and the five-axis machining center of crane type can meet these high-precision machining requirements. -High-speed machining: Equipped with advanced drive system and transmission device, it can achieve fast feed and movement speed and improve machining efficiency. For example, the axial feed rate of some crown block type five-axis machining centers can reach a very high level, which can greatly shorten the processing cycle in the case of mass production or high requirements for processing efficiency. 3. Advantages of processing technology: -Complex parts processing capability: can process all kinds of complex surfaces, special-shaped parts and parts with special requirements. Whether it is aerospace parts with complex shapes, or automobile moulds and medical equipment parts with high requirements for precision and surface quality, the five-axis machining center can process them efficiently and accurately. -Good machining surface quality: Due to its high-precision motion control and stable machining performance, it can reduce the vibration and error in the machining process, thereby improving the quality and finish of the machining surface and reducing the subsequent machining cost.
