The purpose of a double column vertical machining center is to achieve the most efficient and economical form of material handling and material placement. This center has a system of multiple, parallel columns that stack on top of each other. It can be placed in many different areas of a facility such as, feeders, pipe exchanges, chain-driven and gas-driven machine rooms, and in large pneumatic tools to name a few.
To perform the best possible assembly, the multi-column vertical machining center can be used to stack. Two layers of material can be stacked together by dropping two or more pieces of sheet metal onto the vertically stacked material. For this process to be effective, the feed mechanism must be able to connect all the layers of material. To ensure that all the layers are properly connected, the feed mechanisms for each material layer must have a very tight connection to the other layers of material.
The machines used for this work are made specifically for stacking. The cost of having a multi-column vertical machining center comes from the process itself. It takes more machines to complete the same job than it does to just have a single machine that uses a screw press to allow for stacking and fastening of materials.
There are several reasons why it is necessary to have a specially designed machine for this process. The first reason is the sheer amount of material that must be supported during this process. Machines for this process can hold in excess of one million pounds of material at a time and can perform a fast rate to quickly remove waste.
The material to be processed must be specifically cut into the required lengths. If there is any doubt about the length of material being fed, the feed mechanism should be checked with the facility manual. The final step involves the positioning of the material onto the machine.
The best double column machining centers can move about four pieces of material per minute. The material must be loaded onto the machine, then turned around so that the end of the material is at the tip of the nozzle. After the material is turned, the feeding tube must be removed so that the product can be slid down the feeding tubes. If this process is done correctly, the stack of material will be properly positioned in the tube.
The accuracy of the machine to allow the stack of material to be correctly positioned is essential. A defect in the machine can cause the stack of material to not be correctly positioned. Failure to perform this operation properly can cause the stack of material to move farther than it is supposed to go.
Another defect in the feed mechanism can cause the stack of material to have a material not delivered at the expected rate. The feed mechanism must be in perfect working order. If the feed mechanism is not operating correctly, the feed mechanisms must be replaced. The machine can be repaired, but if it fails completely, the machine must be taken out of service for repair.
