Typical CNC Machining Center with CNCis a multi-axis equipment of complex design, in which control is carried out by means of two controllers: responsible for the coordinates of the axes and the main one, directly executing the PLC program.
Machining center for metal with CNC is capable ofSimultaneous processing of parts from different sides. Production speed is halved, profitability is increased, and accordingly labor costs are reduced with the same product cost for the consumer. Complex machines can carry out both turning and milling processing.
Machining center for metal with CNC selectaccording to the terms of reference, which are dozens of employees. Here we take into account the possibility of the machine to perform the loading, unloading of the part in automatic mode, the type of processing, cooling. Also taken into account is the type of workpiece material and rigidity of the machine design.
A CNC machining center can haveinterfaces for sending reports to the upper level, the ability to create programs in a single enterprise environment, and also takes into account the way the workpiece is held. So, for long parts the antispindle is installed, and the wide products are clamped into special cams.
Do not forget about feeding parts to the machine.It can be a coordinate robot or feeder for special rods. Often chosen for multi-purpose turning and milling work are versions of equipment with fastening tables, on which are installed universal fastening bases.
Universal machining centers with CNC formetal are divided by the level of complexity, by the presence of an antispindle unit. A drive center or additional axis can also be added to make hard-to-reach notches, grooves, holes. Multi-axis systems are equipped with complete software for designing parts and creating machine codes.
Turning and milling works are carried out at highintensity, and any, even a small oversight of the operator can cause a long idle equipment. The drivers are required to undergo training before performing the simplest cutting cycles. All the computational operations are performed by the machine itself, but there are blockages that the maintenance personnel have the right to take during the reconfiguration.
CNC machine tools for metal are often equippedshops for the tool. Each cell is calibrated before the program is executed using cutting technology. The computer centers are able to insert the required tool into the spindle unit independently. The shift order is set by the adjuster. Stores can contain 20, 40 or more items for each type of part processing.
The store for the tool is supplied with its owncontroller that facilitates the ways of output from emergency situations. For turning, the equipment is equipped with turrets with several positions for the cutters. Change of the latter occurs by rotating the disc of the head.
CNC machineworks in multichannel mode: several instruments, the shop itself, pallets of unloading and loading move simultaneously. Such an organization allows you to make the entire process continuous. One center is able to replace up to 5 conventional CNC machine tools due to its productivity.
Replacement of several machines for one powerfulThe machine can be beneficial in terms of space savings in the office space, reducing the number of employees. After all, a complex machine can be serviced by one employee. The driving tool on turret heads comes in rotation from one engine thanks to the precise mechanics. This simplifies the design of the machine and helps to perform a huge number of operations in one zone.
The whole chain of operations is replaced by a set of instructionsone machining center. On the simplest machine tools it is sometimes impossible to perform certain types of work with high accuracy. Such works include milling of parts from worm gears. It will also be difficult to crank the crankshaft.
Not less difficulty in processing possessgear parts. Due to several interceptions, complete processing of the part from all sides is carried out. The counter spindles are used for recessing parts more than 30 mm, which helps to avoid the beating of the tool and the appearance of waves on cylindrical surfaces.
One processing center is able to replace allequipment installed in the process chain. The versatility of its use makes it possible to achieve increased productivity in furniture factories, in sheet bending shops, in the defense industry and in the automotive industry. Often, machining centers are required in case production, when frequent changeovers are necessary for small series of parts.
The entire machine design is located on oneWelded frame, which has a huge weight. The balancing is carried out due to several jacks. The accuracy is adjusted during the installation phase. At the stage of putting the machine into production, the state of each axis is evaluated. The straightness deviation does not exceed 0.02 microns, which makes it possible to produce parts even for the aviation industry. At all stages of operation, the position of the tool is always monitored by position sensors.
