Slotting Machine Manufacturers in India

Slotting Machine Parts

A slotting machine consists of the following parts;

Base
Column
Saddle
Cross-slide
Rotating or Circular table
Ram and tool head
Ram drive
Feed drive

Base:

It should be sustainably rigid to take up the entire load of the machine. It has to take all the load(dynamic as well as impact loading) while operating. The guideways for the same are perpendicular to the column face accurately finished to move the saddle quickly and easily.

Most generally it is made up of cast iron.

Column:

The right vertical cast integral rigid part of the base is the column and it serves the following purposes.

It houses the driving mechanism of the ram reciprocating on its front vertical face.
It is also capable of housing the feeding mechanism of the table.
It subsequently moves on the guideways on the base to provide a longitudinal feed of the table, i.e. in a perpendicular direction to the front vertical face of the column.
It is also capable of providing guideways on its top face perpendicular to the guideways on the base for the cross-slide.
Although the longitudinal feed may be given either manually or by power.

Cross-Slide:

It is generally mounted on the guideways of the saddle and can provide cross-feeding of the table.

Cross-slide holds the circular table.
It generally provides the arrangement of cross-feeding either annually or by power.

Circular or Rotating Table:

It holds the ability to rotate on the cross-slide to provide circular feeding of the work.
It can definitely hold back the work by clamping, using fixtures and fixing vices, etc.
It does have the arrangement of the rotary feeding either by hand or by power.

On certain machines the table graduates in degrees for indexing.

Ram and Tool Head:

Ram generally slides on the guideways mounted on the vertical face of the column and provides a slot for changing the position of the stroke. It does carry the tool which is mounted at the bottom end of the tool head.

Ram-Drive

It provides the circular motion of the motor to the reciprocating motion of the ram in the vertical phase. It provides the arrangement with a slower speed during the cutting or forward stroke and greater speed during the return stroke to reduce the idle time.

Feed Drive:

It provides the arrangement of the longitudinal and crosses- a feed of the table either by power or manual and provides the arrangement of the circular or rotary feeding of the table either by power or manual.

Intermittent feeding of the table is supplied at the beginning of each cutting or forward stroke of the ram.

Mechanism of Slotter Machine

· Hydraulic Drive

· Variable Speed Motor Drive

Hydraulic Drive

The speed motor drives a hydraulic pump delivering oil at a constant pressure to the line. The regulating valve admits the oil under pressure. A regulating valve admits oil under pressure to each and every piston alternatively at the same time allowing the oil from other end to reach the reservoir

The piston that is pushed by the oil and connected to the ram by the piston rod pushes the ram carrying the tool.

The relative admission of oil to each end of the piston alternately is accomplished with the help of the trip dogs and pilot valves.

As and when the ram moves and completes its stroke, a trip dog will trip the pilot valve operating the regulating valve. The regulating valve admits oil to the other side of the piston and the motion gets reversed.

Also, the length of the ram stroke will depend upon the position of the trip dogs and can be changed by unclamping and moving the trip dogs to the desired position.

Variable Speed Motor Drive:

In this variant of the slotter, speed is obtained by different gears present in the gearbox and the shaft rotates with the help of the electrical motor.

Technically it is used in the larger slotter machines.

The Working Principle:

The definite working of the Slotting Machine is somewhat similar to the shaper machine, just the main difference lies in the fact that the slotter machine works vertically whilst the shaper works horizontally.

Now the ram connected to the crank and the crank is connected to the gears. So what happens here is that when we increase or decrease the gear speed, the rotation of the crank increases and decreases. And as per these, the ram moves up and down.

Esskay Lathe Machine Tools, One of the Top Notch Lathe Machine Manufacturers, have attached the workpiece to the work table and manually we bring them up near the workpiece, then adjust the worktable and clamp it up.

Now we supply the power as per gear the crank rotates and the crank is connected to the ram so the ram moves up and down.

When it moves down the cutting stroke takes place and while moving up or return stroke there is no cut.

If we have to cut at the different sections then manually we give feed to the work table and as per the requirements, it cuts. That’s how it works.

When do we require Slotting Machine Operations?

Internal and External Flat surface machining
The internal recess of circular, semi-circular and concave-convex surfaces.
Internal, external circular surfaces machining and Blind Holes Internal machining.
For shaping internal and external forms or profiles.
The machine operates vertical, Horizontal and at some angle too (Inclined Surfaces).
Irregular surface machining.
Machining operation of Dies and Punches.
The operation like slots, grooves, splines, and keyways for both internal and external surfaces.
Internal and external gear teeth machining.

Knife Grinding Machine Manufactures

Introduction of
Knife Grinding Machine

Blade Grinding Machine is Known with a few names like , Knife Grinding Machine, Edge Grinding Machine, Surface cum Edge Grinding Machine, Knife Sharpening Machine, Blade Sharpening Machines.

All Machines are comparative with little changes, Knife Grinding Machine are proficient to granulating on edges, knifes to make it more keen with certail points according to client requirement.Blade Grinding Machines gave two variations , one is bunching framework and other is Magnetic Chuck System

Sharp edges are fitted on the table with amassing or attractive hurl framework, attractive toss holds the blades, edges firmly for pounding the edges.Machine table can do granulating in the middle of o to 90 degrees point.

• Complete with electrical and electric engines

• Grinding head accessible with 6 or 8 crushing stones or according to prerequisites Application Areas.

• Used for honing guillotine paper cutting blades

Overview

Knife Granulating Machine furnished with Complete electrical and electric engines , 2nos. of 3 stage engines ,Coolant Pump framework , fine inner bits for great cooling, water waste and simple cleaning , Grinding head accessible with 6 to 8 granulating stones , Knife honing machine is use for honing guillotine paper cutting blades.

The more modest the point between the edge and stone, the more keen the blade will be, yet the less side power is expected to twist the edge over or break it off. The point between the cutting edge and the stone is the edge point – the point from the vertical to one of the blade edges, and equivalents the point at which the edge is held. The all out point from one side to the next is known as the included point – on a symmetric twofold ground edge (a wedge shape), the point from one edge to the next is along these lines double the edge point. Average edge points are about 20° (making the included point 40° on a twofold ground edge).[1] The edge plot for sharp blades can be just 10 degrees (for a 20° included point). Blades that require an intense edge (like those that cleave) may hone at 25° or more.

Various blades are honed diversely as indicated by crush (edge calculation) and application. For instance, careful surgical blades are incredibly sharp however delicate and are by and large discarded, instead of honed, after use. Straight razors utilized for shaving should cut with insignificant pressing factor, and subsequently should be exceptionally sharp with a little point and frequently an empty crush. Ordinarily, these are honed every day or all the more regularly. Kitchen blades are less sharp, and for the most part cut by cutting instead of simply squeezing, and are prepared day by day. At the other limit, a hatchet for slashing wood will be less sharp still, and is essentially used to part wood by hacking, not by cutting, and might be reground but rather won’t be honed day by day. As a rule, yet not generally, the harder the material to be cut, the higher (more blunt) the point of the edge.

The piece of the stone influences the sharpness of the edge (a better grain, typically, however not generally, produces more honed cutting edges), as does the creation of the edge (a few metals take and keep an edge better compared to other people). For instance, Western kitchen blades are normally made of gentler steel and take an edge point of 20–22°, while East Asian kitchen blades are customary of harder steel and take an edge point of 15–18°. The Western-style kitchen blades are for the most part in the scope of 52–58 on the Rockwell scale, which means the general hardness of a material.
