Makino milling machine production is
from July 2015 to start selling to specialise in aluminum alloy die casting parts finishing the use of “a40” horizontal machining center.The product without the function of heavy cutting, so the spindle rotation, XYZ axis movement and the cutting tool replacement more agile, can make the finishing homework time shortened by 25%, at the same time, in order not to let chip in the way, also strengthened the scraps discharge capacity, can prevent the interrupt processing.Makino is expected, affected by the global auto demand, used for the realization of lightweight aluminum die-casting parts will also increase, so the product is developed, and on June 24, 2015 in as the main demand with the release of North America.
general to implement additional processing aluminum die casting parts, such as the flat part of the form is used to install other parts, machining screw hole and screw thread processing, etc.These additional processing with machining center, cutting tool and workpiece contact time actually only half, half the time spent in changing cutting tool and the tool to the processing on the part of the operation.The key is to shorten the cutting time, stop the restart of the spindle and replacing tool to set by the speed of the startup time.Makino, through the method of spindle miniaturization, reduce the inertia force, shorten the start-up time.Thus will compete model usually takes more than 1 second startup time (the time required to 12000 RPM) reduced to 0.45 seconds.Cutting tool replacement in
, in a typical case to happen every 10 seconds time, to as high as millions of times a year, as a result, even change a shorter time is less than 1 second, accumulated can also save a lot of time.New products of the main shaft for 40, but its size and 30 spindle basic same, so that the inertia force decreased by 65%.Due to the length of the drive shaft rotation of motor rotor is shorter, in order to make up for it, increase the input voltage to 400 v, to ensure the enough torque and rotational speed.
in addition, when screw thread processing to tapping segment clockwise screwing in the hole processing, and then pull reversal, so the spindle will stop.New product also shortened the time needed for the job, and the speed of the screw thread processing itself from the usual 3000-4000 RPM to 3000 RPM.
due to the main shaft to realize lightweight, therefore the X, Y axis is more agile movements.Accelerated the increase of the acceleration, the greater the acceleration, so that to achieve constant acceleration time reduced by half.In driving the workbench of Z axis and B axis rotary worktable, joined the “inertia force control functions”, will detect the workpiece weight, lighter in weight when using high acceleration.
to wreck a automatically stops when processing in cutting tools, the new product standard to tool irradiation light, through the image detection tool technology.The check just 0.1 seconds.Due to the use of the probe and the check methods of contact takes 0.7 seconds, so changed to use image processing means of non-contact inspection methods.
in recent years, the precision of the aluminum alloy die casting technology, constantly improve the finishing the required cutting allowance has become very small, so the processing done in a very small load.But the problem is the number of the number of parts and the machining of screw has not been reduced.Therefore, processing enterprises hope to offer a large number of light cutting machine tools.Animal husbandry, according to “shorten the operation time 25% had a huge effect on reducing costs, even if the machine more, is enough to back to this”.The biggest workpiece diameter of 630 mm,
a40 largest workpiece height is 900 mm.Axial travelmotion of X 560 mm, Y Z axes 640 mm.The largest workpiece weight is 400 kg.X, Y, Z axis feed speed up to 60000 mm\/min.Fuselage size is 2410 * 4249 * 4249 mm wide, weighs 6000 kg.
