What is the mechanism of Slotter machine?

Drive Mechanism of Slotting Machine:- In slotting machine, the metal is cut during the upward stroke and no metal is removed during the downward stroke. So, the time taken in downward stroke can be reduced to improve the working speed of the machine.

What is Slotter machine?

A slotter machine is one the oldest machine tool that exist, which was invented for BRUNEL. It is much similar to the vertical shaper machines as the ram carrying the slotting tool reciprocates in a vertical guide-way of the machine. This machine can produce flat and contour surfaces, slots and internal grooves.

What are the principal parts of a slotter?

PRINCIPLE PARTS OF A SLOTTER

• Bed or Base. It is made up of cast iron.
• Table. It holds the work piece and is adjustable in longitudinal and cross-wise directions.
• Hand wheels. They are provided for rotating the table and for longitudinal and cross traverse.
• Column is the vertical member.
• Ram.
• Cross-slide.

Which angle is provided in Slotter tool?

The clearance angle (COG in Figure 17-10) should be 4° or 5°, and the rake angle (BOF in Figure 17-10) should be 10° or 12°. When the cutting tool is clamped to the end of the ram in a horizontal position, the clearance and rake angles are measured in the same manner as for planer tools.

What are the applications of Slotter?

These are the applications of a Slotter Machine:

• It is used for cutting Slots, Spline and Keyways, both internal and external.
• It is also used for the Machining of internal and external gears.
• Internal machining of blind holes.
• It is used for light cuts.

Which of the following is Slotter feed mechanism?

Longitudinal feed: This movement is achieved by moving the saddle either towards or away from the column. Cross feed: This is obtained by moving the cross slide parallel to the face of the column. Circular feed: This is obtained by rotating the table about a vertical axis.

What feed is involved in Slotter?

What is the difference between shaper and slotter?

In a shaper machine, the reciprocating motion is done by the tool. In a planer machine, the reciprocating motion is done by the workpiece. In a slotter machine, the reciprocating motion is done by the tool. In a shaper machine, the reciprocating motion is done by the tool in a horizontal direction.

What is difference between vertical shaper and slotter?

1. Shaper is commonly used to make flat surfaces. Slotter is use for cutting groove, keyways and slots on inside and outside surface.

Why quick return mechanism is used in shaper?

Quick return is a common feature of tools in which the action is performed in only one direction of the stroke, such as shapers and powered saws, because it allows less time to be spent on returning the tool to its initial position.

What is the difference between shaping and slotting?

Shaper is commonly used to make flat surfaces. Slotter is use for cutting groove, keyways and slots on inside and outside surface.

What are the types of quick return mechanism?

Types of Quick Return Mechanism:

• #1. Hydraulic Drive- Working of Hydraulic Drive:-
• #2. Crank and Slotted Link Mechanism- Working of Crank & Slotted Link Mechanism:-
• #3. Whitworth Mechanism-

What is shaping machine operation?

Shaping is the operation of removing a layer of material from the flat surface of the workpiece using a reciprocating single-point cutting tool.

What is quick return mechanism explain?

A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. It is driven by a circular motion source (typically a motor of some sort) and uses a system of links with three turning pairs and a sliding pair.

How do you specify a slotter?

To specify a slotter correctly the diameter of the table in mm. Amount of cross and longitudinal travel of the table expressed in mm. The number of speeds and feeds available, h.p. of the motor, floor space required etc. should also be stated.

What is the use of a slotter?

Slotting machine is used for cutting grooves, keys and slotes of various shapes making regular and irregular surfaces both internal and external cutting internal and external gears and profiles. Slotter machine can be used on any type of work where vertical tool movement is considered essential and advantageous.

Which mechanism is used in a slotting machine?

Which mechanism is used in a slotting machine? 1. Hydraulic Drive (Greater speed Flexibility, Smoother operation, Stroke length can be adjusted ) 2. Variable Speed Motor Drive (In this Multi-speed arrangement)

What are the specifications of Slotter machine?

The specifications of a Slotter Machine is depended on the several factors some of these are: It is used for cutting Slots, Spline and Keyways, both internal and external. It is also used for the Machining of internal and external gears. Internal machining of blind holes.

How does a puncher Slotter work?

The Ram of the puncher slotter is driven usually by the meshing of the spiral pinion with cut rack teeth on the ram’s underside. Pinion here gets driven by reversible electric variable speeds motor that is very similar to a planer. Electrical gears control the feed.

How does a tool room Slotter work?

The ram is usually driven by a spiral pinion meshing with the rack teeth cut on the underside of ram. The pinion is driven by a variable speed reversible electric motor similar to that of a planer machine. The Feed is controlled by electrical gear. The tool room slotter works with good machine speed and produces an accurate surface finish.
