Slotting Machine Components
Base or Bed
| Description |
|---|
| The base is rigidly built to take up all the cutting forces and the entire load of the machine. |
| The top of the bed is accurately finished to provide guideways on which the saddle is mounted. |
| The guide ways are perpendicular to the column face. |
Column
| Description |
|---|
| The column is the vertical member which is cast integrally with the base and houses driving mechanism of the ram and feeding mechanism. |
| The front vertical face of the column is accurately finished for providing ways in which the ram reciprocates. |
Saddle
| Description |
|---|
| The saddle is mounted upon the guide ways and may be moved toward or away from the column either power or manual control to supply longitudinal feed to the work. |
| The top face of the saddle is accurately finished to provide guide ways for the cross-slide. These guide ways are perpendicular to the guide ways on the base. |
Cross-slide
| Description |
|---|
| The cross-slide is mounted upon the guideways of the saddle and may be moved parallel to the face of the column. |
| The movement of the slide may be controlled either by hand or power to supply crossfeed. |
Rotary Table
| Description |
|---|
| The rotary table is a circular table which is mounted on the top of the cross-slide. |
| The table may be rotated by rotating a worm which meshes with a worm gear connected to the underside of the table. |
| The rotation of the table may be effected either by hand or power. In some machines, the table is graduated in degrees that enable the table to be rotated for indexing or diving the periphery of a job in the equal number of parts. |
| T-slots are cut on the top face of the table for holding the work by different clamping devices. The rotary table enables a circular or contoured surface to be generated on the work piece. |
Ram and Tool Head Assembly
| Description |
|---|
| The ram is the reciprocating member of the machine mounted on the guideways of the column. It supports the tool at its bottom end on a tool head. |
| A slot is cut on the body of the ram for changing the position of the stroke. |
| In some machines, special type for tool holders is provided to relieve the tool during its return stroke. |
Ram Drive Mechanism
| Mechanism Type | Description |
|---|---|
| Whitworth quick return mechanism | This mechanism is commonly used in slotting machines. It consists of a slotted lever and a connecting rod. The rotary motion of the drive is converted into reciprocating motion of the ram with a quick return stroke and a slower cutting stroke. |
| Variable speed reversible motor drive mechanism | In this mechanism, a variable speed reversible motor is used to drive the ram. It allows for adjusting the speed and direction of the ram's reciprocating motion, providing flexibility in the machining process. |
| Hydraulic drive mechanism | This mechanism utilizes hydraulic power to drive the ram. It offers smooth and precise control over the ram's movement, allowing for efficient metal removal during the cutting stroke. Hydraulic drive mechanisms are often used in high-performance slotting machines. |
