The 5-axis control of the MC itself is not uncommon, but in the past it was basically a large device. The large 5-axis control MC has a large footprint, and the cost of plant land and facilities is higher. Moreover, the amount of power consumption and the amount of compressed gas are also high, so the operating cost is high. At the same time, the machine itself is also expensive.
In view of these circumstances, mold manufacturers and medical device manufacturers engaged in the small-sized workpiece cutting business with complicated shapes have demanded the use of a small 5-axis control MC. In the past, Sugino Machinery was producing small MCs with spindle tapers of 20 and 30, and has been considering the development of MC with higher added value.
The new small 5-axis control MC is equipped with a "cradle-like" bracket with a turntable in the center on the 3-axis control vertical MC. In other words, one side of the spindle moves in the X-axis direction of the X, Y, and Z axes, and the side of the table that fixes the workpiece uses the A-axis (the axis outside the X-axis, the rocking axis) and the C-axis (the axis outside the Z-axis). To turn. The strokes of the X, Y, and Z axes are 300, 300, and 200 mm, respectively. The rotation of the A-axis is ±90°, and the C-axis is continuous rotation. The maximum spindle speed is 40,000 rpm and the maximum C axis speed is 200 rpm.
The A-axis and C-axis are rotated using a direct drive motor (DD motor) from Siemens, Germany. The reason for using this motor is that because the tooth gap is small, "the perfect surface machining can be performed, and the program can be simplified by controlling the vector command control of the tool blade direction".
The new small 5-axis control MC is not only suitable for high-precision machining, but also has a shorter processing time because it uses a flexible and mechanical machine to cut small workpieces.
The company did not announce the comparison data of the new small 5-axis control MC and the large 5-axis control MC, but announced the comparison data with the old-fashioned small 3-axis control MC. In other words, it is expected that the current small-axis 3-axis control MC customers will benefit from the new small 5-axis control MC. Comparative data shows that operating costs and production lead times can be cut by 70% and 40%, respectively.
Sugino also exhibited a large number of samples processed using the new small 5-axis control MC. Not only molds, but also processing of medical products and spectacle lenses.
Aluminum plate refers to the aluminum material with a thickness of more than 0.2mm to less than 500mm, a width of more than 200 mm, and a length of less than 16m, which is called aluminum plate or Aluminum Sheet. Aluminum plate with a thickness of less than 0.2mm is called aluminum material, and aluminum plate with a width of less than 200 mm is called row material or strip material (of course, with the progress of large equipment, there are more aluminum plates with a maximum width of 600 mm).
Aluminum plate refers to the rectangular plate rolled by aluminum ingot, which is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium thick aluminum plate and patterned aluminum plate.
