ifferent needs. (2) The multiaxis machine tool turret Turret to install more nonadjustable or universal coupling spindle box, turret can automatically switch to digital, and clamp the workpiece in the rotary table to feed motion. Through the rotary table can be a number of workpiece surface. Because the turret not be too big, so it is generally not exceed the median of workers 46. And the spindle box is also not too large. When the machining process more objects, size larger, it should automatically replace the machine tool spindle box fit, but its simple structure. (3) Automatic replacement of modular machine tool spindle box It consists of automatic line or a bination of standard machine parts. Nonadjustable multiaxle box and power box by home base in the horizontal, the spindle rotates, the entire case library fastening device to the system in the slip into the board. Library Headstock rotation and feed movement is based on standard routines of work. Headstock time for a few seconds. Clamping the hydraulic subdegree rotary table so that each workpiece surface. Good fruit rotary table acpanied by discharging device, we can coflow production automation. In the variable production system using this device, acpanied by the corresponding controller can obtain a plete processing system. (4) 8axis CNC drill floor Large condenser water wall tube plate holes as many as 15,000, which linked together with the support plate processing. Diameter of 20 mm, hole depth 180 mm. Used inside the cooling pipe has a twist drill ,57 bar pressure, coolant directly into the cutting area is conducive to chip removal. And ground into a 90 176。 drill point for the selfcentering. Durable than regular twist drill, and a large quantity of feed. To shorten the processing time to 8axis CNC machining floor. trends in multiaxis machining :Multiaxis machining high production efficiency, low investment and production preparation cycle is short, product modification, when a small loss of equipment. And as China39。s CNC technology, the scope of multiaxis machining will bee the broad, processing efficiency will be improved. production tasks :A group of castiron joints have the same surface processing with multiple holes. In the general processing of vertical holes on the drill, usually a hole a hole drilling, production efficiency is low, use nonstandard equipment, that is, bination of machining, production efficiency is high, but the large investment in equipment. However, the number of mon vertical drilling machine to transform ordinary singleaxis vertical multiaxis drilling machine after transformation, multiaxis drilling machine can simultaneously perform multiple hole drilling, expansion, hinges, and other processes.
