Parts, Types, Operation, and Applications of Tool and Cutter Grinder.

 

                           

Today's subject matter is associated with "device and cutter grinders," wherein you'll find out about their parts, types, and uses. Tool and cutter grinding machines are the sorts of grinding machines like floor grinders, cylindrical grinding machines, centerless grinding machines, etc. In the gadget shop, most of the machining operations are executed with the aid of a single-factor reducing device or a multipoint reducing device. Continuous use causes the reducing device to become blunt and needs to be resharped for non-stop production. Such resharpening is finished with the aid of the device and cutter grinder gadget. Tool and cutter grinders are used especially to sharpen and recondition multipoint equipment like drills, reamers, milling cutters, taps, hobs, broaches, etc., and for correct grinding of the angles of single-factor equipment. With appropriate attachments, those grinders can also be used for mild cylindrical floors, inner grinding operations on gadgets like jigs and fixtures, gauge elements, etc. So, without losing time, let's get started.

 

 

What is a Tool and Cutter Grinder?

 

A tool and cutter grinder is a machine used for shaping and sharpening a tool or cutter by means of abrasive wheels.

 

It can be operated both hydraulically and electrically.

 

 

Parts of a Tool and Cutter Grinder

 

The following parts are used in the tool and cutter grinding machine.

 

• Base
• Saddle
• Table
• Column
• Wheel Head
• Tailstocks

 

Shown in the figure are parts of the tool and cutter grinder, which are described below in detail.

 

Base

It is a strong, heavy, box-type construction that supports all the other parts of the machine.

 

 

Saddle

It is mounted directly on the top of the base, which carries the table raised and traverses the table movement crosswise.  

 

 

Table  

It rests or moves on the top base mounted on the saddle, which reciprocates.

It can be swivelled at a certain angle. 

 

 

Column

It is fixed on the back of the machine.  

 

It has a wheel head that moves up and down depending on the depth of the cut.  

 

 

Wheel Head

It is mounted on a column on the back of the machine, which can be swivelled at a certain angle.

It has grinding wheels which might be geared up on each end of the spindle.

 

Tailstocks

Right, and left tailstocks are placed between the centres to support the mandrel.

 

 

Grinder Tools and Cutter Types

 

There are the following two types of tools: cutters and grinders.

 

1-Grinders and universal tools

 

2-Single-Purpose Tools and Cutter Grinders

 

 

 

Grinders and universal tools

 

The Universal tool and cutter grinder can be used for sharpening a variety of tools and milling cutters.

 

Universal tool and cutter grinders are often used for sharpening reamers, taps, single-point tools, dies, punches, milling cutters, etc.

 

 

 

Single-Purpose Tools and Cutter Grinders

 

Single-purpose tools and cutter grinders are used for grinding tools such as drills, tool bits, etc. in a large production plant where the volume of production is a high and large number of similar tools need to be ground frequently.

 

 

Characteristics of grinder tools and cutters

 

The tool and cutter grinding machine.

 

1-It can be held at the maximum diameter of the wheel.

 

2-It can be ground to the maximum height of the job or workpiece.

 

3-It can be ground to the maximum length of the job or workpiece.

 

4- It can be ground to the maximum breadth of the job or workpiece.

 

 

 

Types of Grinding Wheels for Sharpening the Milling Cutter 

 

Grinding wheels of the following kinds are frequently used for sprucing the cutters:

 

1-Straight Wheel

2-Dish Wheel

1- Straight Wheel - For straight wheels, grain size 36 or 46 should be selected.

2- Dish Wheel - The grain size for dish wheels should be between 36 and 80.

 

Abrasives (A), Grades (I to L), Structure (S), and Bond (V) should be used to get a good finish.

 

 

Follow-Up Points for Sharpening Cutters

 

1- Keep the face of the grinding wheel clean.  

 

2- Mount the tooth rest correctly.

 

3- Use the correct speed and feed.

 

4- Use coolant.

 

5- Do not remove too much material at the same time.
