Equipped with Siemens "digital native" Sinumerik One, with the help of the digital twin function, the machine tool debugging, parts pre-production simulation, prediction and production process optimization can be carried out in the virtual environment, which can reduce the processing errors of parts and improve the production efficiency of the machine tool. The machine tool is used in oil and gas, machine tool manufacturing, mold production, forestry machinery, rail transit and many other industries, covering the processing and production of various sizes of parts including frame, shaft, valve, boom and so on.
Shandong Weida Seiko Intelligent Equipment Co., LTD. HMF2040 floor type five-sided machining center, Y double screw double balance cylinder rectangular arrangement, not only improve the fast moving speed, but also play a role in compensating the overhanging ram; The main gearbox is placed in the middle, which reduces the length of the coupling and improves the transmission efficiency. Frame in frame type column slide structure, full symmetrical design, good thermal stability, high accuracy retention; The four lines of the ram are arranged in a cross and orthogonal way, the force is reasonable, and the overhang of the ram is small. HMF2040 floor type five-sided machining center can realize efficient milling, spiral milling, hole making, boring and other processing of large parts, with good dynamic performance, and can realize multi-angle machining of various parts, especially suitable for occasions with more empty stroke or high processing speed requirements.
Qingdao Huiteng Machinery Equipment Co., LTD. TK6916 CNC floor boring and milling machine is a typical large size, heavy cutting milling and boring machine. The machine adopts the typical floor boring layout of single column and side hanging box; Bed, column, spindle box and other important parts are cast iron; X/Y/Z axis guide rail is a static guide rail, with high/middle/low three gears, with a large transmission ratio, high torque, high resistance characteristics.
2. Product and technical analysis
The exhibition floor milling and boring machine exhibits have increased compared with the previous session, the exhibits mainly show the latest breakthroughs in high-speed, high-precision, composite and other directions of the manufacturers, these characteristics are fully reflected in the above introduced exhibits.
In terms of high speed, Italy's PAMA company SPEEDMILL 3000B horizontal floor boring and milling machine, Spain's SORALUCE company FSW floor boring and milling machine, Shandong Weida HMF2040 floor five surface machining center linear axis are all using large size linear roller guide, so that the linear axis has high speed and fast moving speed, while having high rigidity.
In terms of high precision, the headstock of Italy PAMA's SPEEDMILL 3000 B horizontal floor boring and milling machine and Shandong Weida HMF2040 floor type five-sided machining center all adopt a vertical thermal symmetrical structure, and the headstock is placed between the doorframe type columns, with high overall rigidity, good stability and good shock absorption. It can meet the requirements of heavy load cutting and reduce the influence of thermal deformation on the machining accuracy of the machine tool when the temperature changes. Shandong Weida HMF2040 floor type five-sided machining center spindle box lifting adopts double screw double motor synchronous center of gravity drive structure, the machine tool dynamic performance is better, to ensure the machine tool processing accuracy. PAMA SPEEDMILL 3000 B horizontal floor boring and milling machine has HTC (static pressure tilt compensation) function, which can automatically detect and compensate the tilt torque caused by the off-load of the table; ATC (Automatic Heat Compensation) function, due to the heat generated by the machining tool caused by spindle extension, CNC real-time control to compensate for it. SORALUCE FSW floor boring and milling machine with DAS dynamic active damping system, through the actuator installed in the ram to apply a real-time reverse vibration force, the machine cutting capacity doubled, production efficiency increased by 300%, while improving the surface quality of the workpiece.
In terms of composite, Italy's PAMA company SPEEDMILL 3000 B horizontal floor boring and milling machine, Spain's SORALUCE company FSW floor boring and milling machine, while retaining the original high efficiency milling and high precision hole system processing characteristics, Equipped with a large capacity tool library, rich milling head accessories (such as CNC swing Angle milling head) and milling head exchange system, accurate rotary table, intelligent CNC system, so that the machine tool has boring, milling, turning, drilling (drilling, expanding, reaming), tapping (rigid tapping), multi-axis linkage surface processing, analog processing and other functions, greatly expanding the milling and boring machine tool processing capabilities. Shandong Weida HMF2040 floor type five-sided machining center ram front end fixed installation of the five-sided head, can automatically rotate the index, to achieve a multi-sided machining workpiece clamping; Minimum indexing unit 1°, strong adaptability.
