Horizontal Mills
Horizontal milling machines, also known as horizontal mills, are characterized by a horizontally oriented spindle that holds cutting tools, enabling the machining of workpieces from different angles.
Horizontal Mills Construction and Design
These Mills have a horizontal spindle that is positioned parallel to the worktable. The worktable is typically mounted on a saddle that can move along the X-axis (longitudinal direction). The spindle itself can also move along the Z-axis (vertical direction). This design allows for flexibility in positioning the workpiece and cutting tools, facilitating efficient and precise machining.
Versatility + Flexibility
They offer versatility in terms of the range of machining operations they can perform. They are capable of various milling tasks, including face milling, end milling, slotting, profiling, and contouring. With the ability to adjust the spindle and the worktable, operators can easily set up the machine to achieve desired angles and orientations, making horizontal mills suitable for complex parts and multi-sided machining.
Material Removal Efficiency
Horizontal mills are known for their high material removal rates. The horizontal spindle orientation allows for efficient chip evacuation during the machining process. Gravity assists in the removal of chips, preventing buildup and reducing the risk of chip recutting or tool damage. This feature, combined with the ability to use multiple cutting tools simultaneously, makes horizontal mills well-suited for heavy-duty cutting and high-volume production.
Workpiece Handling + Automation
Horizontal mills can be equipped with pallet changing systems that allow for the setup of multiple workpieces or fixtures in advance, streamlining production and minimizing setup times.
Horizontal Mills Specialized Applications
These Mills are particularly suitable for certain specialized applications. For example, horizontal boring mills are designed for machining large and deep holes in workpieces. They often have additional features, such as adjustable facing heads or rotary tables, to facilitate specific operations. Horizontal mills are commonly used in industries such as aerospace, automotive, energy, and mold-making, where the ability to machine large, complex parts is critical.
The common types of horizonal mills are:
Plain, Bed-type, Boring, and HMCS.
Plain Horizontal Milling Machines
Also known as horizontal knee-and-column milling machines, Horizontal Milling Machines are the most basic type of horizontal machines. They have a horizontally oriented spindle and a worktable that can move in both longitudinal and transverse directions. The worktable is typically mounted on a saddle, which can be moved vertically.
Horizontal Bed-Type Milling Machines
Featuring the worktable mounted directly on the bed, Horizontal Bed-Type Milling Machines providing increased stability and rigidity. The bed can move longitudinally, while the saddle moves vertically, and the spindle remains fixed. Bed-type milling machines are known for their robust construction and are commonly used for heavy-duty machining operations.
Horizontal Boring Mills
Designed specifically for boring large holes in workpieces, Horizontal Boring Mills typically feature a spindle that can be adjusted vertically and horizontally, allowing for precise positioning of the cutting tool. Horizontal boring mills are often used in industries such as aerospace, automotive, and construction, where deep and precise bores are required.
Horizontal Machining Centers
HMCs are highly automated milling machines that combine horizontal milling capabilities with the advantages of CNC technology. Horizontal Machining Centers feature a horizontally oriented spindle, a worktable that can move in multiple axes, and an automatic tool changer. They are equipped with advanced control systems, allowing for high-speed and high-precision machining operations. HMCs are commonly used for complex machining tasks, such as multi-sided part machining and simultaneous operations.
