Robotic milling is the concept of leveraging the flexible nature of industrial robots to modify conventional CNC (computerized numerical control) machining applications like cutting, milling, drilling, and routing. There are different types of milling machines. In this article, we shall discuss the pros and cons of horizontal and vertical milling processes. While both horizontal and vertical machining systems have pros and cons, they are critical for manufacturing plants. Vertical milling systems come with a vertically oriented cutting head and a spindle that advances above and below the z-axis while pressing across a workpiece to shred material. The remaining part of the machine repeatedly places the product to facilitate cutting by shifting along the y-axis and x-axis, while creating a direct visibility line as the machine cuts. There are two different vertical mills which are turret and bed mills. Each of them comes with various pros and cons based on the application type. They include: Less upfront cost is involved during the implementation of a vertical milling machine robot. What’s more, projects done using vertical milling are cheaper, meaning that consumers benefit from the manufacturing savings. Vertical mills do not require extra fixtures and this makes them easy to operate. They come with enhanced visibility allowing operators to identify potential issues during the milling process. Vertical machining stations are the most commonly used milling machines in the metalwork sector. As a result, finding expert machinists conversant with these systems and replacement parts is easy. There are numerous reasons why vertical mills are optimal for small manufacturing plants and shops such as fast milling tasks, affordability, user-friendliness, and the fact that they require minimal floor space. Lifting and lowering these machines along the vertical platform can be a difficult task. As a result, they do not function well for heavy items. Vertical machining systems cannot cater to cost and time efficiency in sophisticated and large quantity machining tasks. They are incapable of executing a fast output rate, unlike their horizontal counterparts. With this limitation, handling some parts becomes difficult, especially if they are sophisticated. Horizontal machining mills feature a horizontally-placed cutting head and spindle. The horizontal mill cutters are short and thick, enabling them to execute deeper, heavier, and quick cuts. They are fixed along the arm and over the table which is also known as an arbor, enabling the horizontal mills to leverage different cutters concurrently. Objects are delivered from three separate axes. The horizontal milling machine is versatile enough to handle groovy and heavy objects. It is mechanically designed to execute multiple tasks at once, which enhances productivity and efficiency. The horizontal mills are designed to execute fast cuts concurrently. They can also be rotated, allowing them to mill from multiple edges than focusing on the horizontal surface. This structure accelerates the process without compromising accuracy. The horizontal machining mill design facilitates the easy removal of chips. As a result, the surface finish will be better; meaning that less fabrication will be required, which guarantees a prolonged tool life. They are Larger and Costly Horizontal milling machines are large machines whose upfront implementation costs can be high. Further, it takes up lots of space, meaning small businesses with limited spaces may not utilize them. Horizontal milling machine systems are not only costly, but maintaining them can be overly expensive. As a result, they are not commonly used and finding skilled operators can be complex. Further, should your machine break down, finding replacement parts can be difficult. Despite the cons, many businesses may need horizontal milling machined due to their advanced output and task accuracy. Often, the machine will cater to its costs. If you are struggling to choose one of these systems over the other, these pros and cons should help you make an informed decision. Pros of Vertical Milling Systems
