Best Manufacturing Tips on Carbide Tools, Cutting Tools, Threading Tools & Boring Tools

Source steel rods are and carbide tips from Kennametal or from another reliable source.

Ensure thorough inspection of steel rods after chemical analysis

Cut steel rods to required length

Mill the front clearance angle of the recessing tools appropriately

Mill the side clearance angle on both sides of the recessing tools correctly and mill a positive top rake angle appropriately

Set and mill the tip pocket of the lathe tools shank parallel to the top rake face

Ensure the De burring of the tool shanks and stamp the designation as ISO 4 or as DIN 4976

Inspect all operations done so far.

Grind the carbide tip or carbide drill bit

Degrease the shanks of the cutting tools and the carbide tips

Procure Silver foil from an approved source

Apply suitable brazing flux on the tip seat area,

Create a sandwich of 2 silver foils and a copper foil in between with brazing flux in between them and place them on the tip seat area, apply brazing flux to the area of the tip that gets brazed, place the tip to be brazed on top of the sandwich of foils

Set the Induction brazing machine with a suitable induction coil and power tapping points.

Insert the recessing tool to be brazed with the carbide tip into the induction coil and start heating.

Stabilise heating when the steel shank turns from blue to mild red in colour.

Start heating again to take the carbide tip and the steel area surrounding it to the melting point of silver which is 650 deg C.

Press the tip into position with a pointer rod and allow the cutting tool to cool to

Remove the tool from inside the induction coil and place it in pre heated sand and allow it to cool to the room temperature.

Inspect the joint to ensure that the carbide tip is brazed properly onto the shank and that the silver has flown properly and that there are no gaps in the joint.

Set and grind the top rake angle, front clearance angle, side clearance angle and corner radius of  on the carbide tips as per drawing and check.  

Carry out final inspection of the tools for dimensions and defects on carbide tips prior to painting.

Some Ways to rethink your strategy in this economy

1. Stop waiting for Clients to reach out to you. Improve your marketing efforts and offer samples and best prices to your customers

2. Do not always look for maximum profit; Work with your clients and settle with a mutually beneficial deal.

3. Create a video's on your website where clients can actually see your company and get a feel of all the Cutting tools & Threading Tools that would be supplied to them. Transparency is the key to success

4. Diversify your list of client and try and market your product in different parts of the world.

5. Cut Operational Costs to the maximum

6. Retain all your employees and may be work with them on a Part Time basis.

7. Be willing to change rapidly, this is the key to survive in any bad economy.

The best way to increase your presence in the web and build your brand is to start sharing your knowledge. Sharing information via blogs, videos, white papers are the best ways to share knowledge. Once you share your knowledge through blogs and videos, this creates a viral effect and other people share the information or comment on the information and your company presence on the web increases. The more information that is written the better it is as your targeted audience would have a very clear understanding that you are good at what you do.

Once they visit your website you need to clearly provide the required information they are looking for. You need to have very clear video's describing what your company is all about and your company could solve their problem. You will also need to have very clear landing pages to get their information and have to respond to them at the earliest.

At last what matters the most is the quality of tools and the price at which you sell them. Interested leads can be given sample tools and if the quality of tools and the price at which you sell them is great there is no doubt you will bag an order.

2] They save time,electric power/energy and material as compared with solid drilling/ boring.

3] They leave a core which can be used for analysing and making other parts while drilling expensive materials.

4] Trepanning is the only process available to manufacturers where in large and long holes have to be drilled.

5] They can be used for drilling large holes in small length parts too.

2] They are made in different grades and are suitable for machining components/parts of Alloy steel, low and medium carbon steel, Cast Iron, Aluminium and all non ferrous materials.

3] These of tools are used for machining components with square shoulders.

4] They are mainly used for turning, facing and boring operations.

5] They can be used for machining chamfers if a suitable angle is ground on the cutting edge.

6] These tools are used in manufacturing small, medium and heavy parts for Aerospace, Automobile, Earth moving, Power generation equipment and other industries.  

1] External Threading Tools:

These tools are used to cut screw threads on the outside diameter of components/parts such as bolts, shafts, pipes, castings and forgings made from ferrous and non ferrous materials.

These tools can be used to cut screw threads in Metric, British, Acme and other standards.

2] Internal Threading Tools:

These tools are used to cut screw threads on the internal diameters of components/parts such as nuts, pipes, collars, castings and forgings made from ferrous and non ferrous materials.

These tools can cut screw threads in Metric, British, Acme and other standards.

The major diameter of the thread has to be machined prior to external threading and the root diameter of the thread has to be machined prior to internal threading.

It is very important to provide an undercut on the outside or inside diameters  before carrying out thread cutting as this allows the threading tool to pass into the undercut just after carrying out threading to the required length and before it returns to the starting point.

While cutting threads it is essential to use a cooling medium such as straight oils or oil in an emulsion with water.

Thread cutting is always done in multiple passes of depths of about 0.1 mm or 0.004 inch to reduce load on the lathe as both cutting edges are working together, maximise tool life and achieve proper thread form to meet gauging requirements.

Overhang of the threading tools is a major factor that contributes to vibration, poor cutting conditions and poor thread form.

As the pitch of threads vary from 0.5 mm to 5.0 mm the rotational speed on conventional lathes are kept low. However, higher speeds can be used in CNC Lathes as the tool return is preset on the machine and controlled.

Care should be taken while setting up for threading so that over run of the threading tool is avoided as it may cause major accidents and damage to the tools and the machine.

Carbide tipped tools are used widely in
1] Mining of Coal, Iron Ore and other ores in the form of Augurs, Cutter Picks, Coal Picks etc.
2] Weld bead removal of Electrical Resistance Welded steel tubes.
3] Aircraft component machining.
4] Cutting off knives in machines that mass produce fasteners, needle roller and other types of bearings.
5] Heavy duty planning machines and roll turning lathes for steel mills and heavy engineering industries.
6] Fine boring machines where the corner radii of the tools are very small.
7] Single spindle and multi spindle automatic lathes that mass produce components with profiled grooves and forms.
8] Chisels that are used in making rough, medium and smooth files.
9] Revolving Centers and Dead Centers.
10] Wood working tools and cutters.
11] Machining of steel, cast iron, aluminium and non ferrous components for all types of industries.

In today's world you should be in a position to have a drink and listen to your customers, their thoughts and opinions. You have to build a relationship with your customers the same way as you have built a relationship with all your closest buddies over the past 40+ years.

Here are five reasons why your customers are like your closest buddies:

(1) You cannot put up an image, you need to be yourself: Your closest friends know you really well and you can't take them for a ride. Similarly, your distributors are no different. You have to be very genuine and cannot put up and image.
(2) Do not brag about yourself: You know the consequences you would face if you brag about your self to your old friends. They will no longer hang out with you. Similarly, you don't have to brag about your products, your distributors and customers know how good or not good you are. Your focus is to try and solve you're their problems
(3) Your friends choose you: You were not born with your friends but you could choose them and they could choose you based on the compatibility level and wavelength. Similarly, you distributors can choose you based on the quality of service and products you provide.
(4) Your friends are straight and upfront: None of your oldest buddies are going to hide any information about you. If something is to be said they would say it out loud and clear. Similarly, your distributors and customers are very straight and upfront and will say what they have to.
(5) Long Relationship: If you survived 30+ years with your friends this means that both your friends and yourself were compatible with each other. Similarly, if you consider you distributor or a customer your friend and build a long term relationship, this relationship would be based on confidence and trust.

Back in 1980's and 1990's for every company to grow, the location was the prime factor. Every city's infrastructure was the primary driver for small businesses to grow. The better the infrastructure of every city, the more the people the city would attract, small business could thrive.

Today location is still a prime factor for a business to thrive but not the only factor. Companies like amazon.com took the advantage of the world wide web and successfully sell most products at the best rates. Our goal is to take our company virtually to the client (by Video's, Blogs and our Website) so that the client can have an understanding of who we are and what Tectools do. We are still at the incipient stages and are hopeful that we can accomplish this task successfully in the future.
