What is Horizontal Machining Center (HMC)?

Horizontal machining center refers to a machining center with the spindle axis parallel to the worktable, which is mainly suitable for processing box-like parts. Its working principle is that after the workpiece is clamped once on the machining center, the computer can automatically select different tools, automatically change the spindle speed of the machine tool, and complete the multi-process processing of multiple faces of the workpiece in sequence. His advantage is that it can greatly improve production efficiency, but it occupies a large area and high cost.


Types and characteristics

Horizontal machining centers are divided into fixed column type and movable column type according to whether the column is moving.


(1) Fixed column type
1) The worktable moves in the cross direction, the worktable moves in the X and Z directions, and the spindle box moves in the Y direction. The spindle box has two types of vertical hanging and side hanging on the column. It is suitable for multi-process processing such as boring and milling of medium-sized complex parts.
2) The headstock moves in the cross direction, the headstock moves in the X and Z directions, and the worktable moves in the Y direction. Suitable for multi-process processing such as boring and milling of small and medium-sized parts.

3) The headstock is hung on the side of the column, and the headstock moves in the Y and Z directions. This layout is similar to the planer-type horizontal milling and boring machine, and the worktable moves in the X direction. Suitable for multi-process machining such as boring and milling of medium-sized parts.


(2) Mobile column type
1) Planer type, the bed is T-shaped, the workbench moves in X direction on the front bed, and the column moves in Z direction on the back bed. The spindle box has two types of vertical hanging and side hanging on the column, and it moves in the Y direction. It is suitable for multi-process processing such as boring and milling of medium and large parts, especially parts with larger lengths.
2) Column cross movement type, the column moves in Z, U (parallel to the X direction), the spindle box moves in the Y direction on the column, and the worktable moves in the X direction on the front bed. It is suitable for multi-process processing such as boring and milling of medium-sized complex parts.
3) The spindle ram feed type, the spindle box moves in the Y direction on the column, and the spindle ram moves in the Z direction. The column moves in the X direction. The worktable is fixed or equipped with a rotary worktable. It can be equipped with multiple worktables, suitable for small and medium-sized parts processing, and the workpiece loading and unloading and cutting time can be overlapped.
