4 Slotting Tool: The slotting tool, also known as the cutter or ram, is a single-point cutting tool mounted on
the ram. It features a cutting edge that removes material from the workpiece as it reciprocates vertically. The
slotting tool may be made of high-speed steel or carbide, depending on the material being machined.
5 Feed Mechanism: The feed mechanism controls the rate at which the slotting tool advances into the workpiece
during the slotting operation. It determines the depth of cut and the speed at which material is removed
from the workpiece. The feed mechanism may be manual, semi-automatic, or automatic, depending on the
machine’s design.
6 Worktable: The worktable is a flat, horizontal surface mounted on the base and supports the workpiece during
the slotting operation. It may have T-slots, clamping fixtures, or rotary tables for securing the workpiece in
position. The worktable can be adjusted vertically and horizontally to align the workpiece with the slotting tool.

7 Cross Slide: Some slotting machines may feature a cross slide that allows for precise positioning of the
workpiece relative to the slotting tool. The cross slide can be adjusted horizontally and vertically to align the
workpiece with the slotting tool and ensure accurate machining.
8 Control Mechanism: The control mechanism includes switches, levers, and knobs for operating the slotting
machine. It allows operators to control the vertical movement of the ram, adjust the feed rate, and start or stop
the machining process.
9 Coolant System: Some slotting machines may be equipped with a coolant system to lubricate and cool
the slotting tool and workpiece during the machining operation. Coolant helps reduce heat generation, chip
formation, and tool wear, resulting in improved machining efficiency and surface finish.

Milling Machine

Introduction of the milling machine:
A milling machine is a versatile machine tool used in manufacturing, machining, and metalworking industries for
shaping solid materials such as metal, wood, plastic, and composites. It operates by rotating a cutting tool against
a stationary workpiece to remove material and create precise features, shapes, and surfaces. Milling machines
are essential equipment in various applications, ranging from small-scale hobby projects to large-scale industrial
production.
