Horizontal boring mills
Horizontal boring mills are typically used for machining large and heavy workpieces because the cutter has support from the arbor as well as a bigger cross-section than the Vertical Boring Mills. The design of the horizontal boring mill allows for the rapid removal of material off the workpiece that is being machined. It has a spindle or cutter mounted on a horizontal arbor above an X-Y-Z table that features a rotary function for machining at different angles.
Vertical Boring Mills
In the vertical machining process, the part to be machined is clamped to a bed and a machining tool is rotated to produce a cylindrical, internal feature on the workpiece. The cylindrical feature to be produced is oriented into a vertical direction and the tool is typically fed down into the workpiece. The Vertical Boring Mills have the spindle that moves in a vertical orientation over the table while working on the top and bottom sides of the parts that have to be machined. The Vertical Boring Mills tend to be taller than they are wide since their operation is vertical which works well when dealing with die sinking, a process used to machine or create specifically sized or shaped cavities in steel blocks. The vertical position is also an advantage in the ease of cleaning cuttings from around the cutting tool.
Typical applications for the Vertical Boring Mills
- Line boring of large machine tool casings and engine blocks
- Machining internal bearing diameters in large castings.
- Finish machining of cylindrical surfaces of very large workpieces
Factors to consider when buying Vertical Boring Mills
Before buying a boring mill whether it is a horizontal or vertical boring mill, it is always important to consider their capabilities and the requirements of the industry. These machines are invaluable resources for any industry that is seeking to create precision pieces but since these machines are major investments, it is best to research on the type that fits the need and not necessarily the budget.
There are actually two versions of the Vertical Boring Mills, the table-type which is largely used for the production of small and medium sized holes and the floor-type which has the capability to create large holes. The floor-type boring mills have higher torque which can be used for urgent boring operations such as roughing out. On the other hand, the table-types have smaller power allocation enough to handle small and medium sized tools. Depending on the specific task that requires the purchase of the Vertical Boring Mills, a company can choose from these major types
