H.B.
Carbide Company, a unit of the Star Cutter Co., is recognized as the
leading top source of tungsten carbide preforms for manufacturing
cutting tools. By consistently producing preforms with minimal
grind stock, H.B. Carbide increases customer productivity while
reducing cost.
H. B.
Carbide offers many different grades of tungsten carbide,
manufactured under process certification ISO 9001:2000.
By using the preforming expertise at
H.B.Carbide, major portions of carbide can be removed from the tool
blank while the carbide is in the 'green' state. Drilling of coolant
holes, prefluting, and grinding different diameters can be
accomplished in seconds at HBC as compared to the slow process of
grinding in the 'hard' state. Therefore, we can leave minimal
grindstock for you to finish grind. This reduction in grinding time
saves you grinding wheel life and increases machine capacity allowing
you higher productivity.
These blanks can include, but are not
limited to:
- Straight Flutes
- Spiral Flutes
- Coolant holes (in any location)
- Stepped Diameters
- Centers (male or female)
- Flats
- Chamfers
- Keyways
- PCD
Pockets
- Preformed sharpening angles
H. B. offers
carbide rods in many different styles.
1.
Solid Round Rod
(RR) Available in 40 different standard RR sizes, unground with
minimal grind stock. These are available in all of our grades, but are
generally stocked in grades HB-2, HB-3, and HB-110. The stock we
maintain is in the 'green' state, allowing us to provide you with
custom cut to length sizes, eliminating your waste of unusable pieces.
2. Tubing (Solid Round Rod
with one hole) All of the standard RR sizes can be provided as tubing, or we
can customize diameters to fit your specific needs. The center hole
can be positioned in the center or moved to a specific point off
center. Tubing is not generally stocked but made to your request.
3.
Ground Round Rod (GRR) Our standard finish is considered polished (6-
8 micro), with OD tolerances maintained at -0.0001"/-0.0004". They are
available as special orders in any of our other grades.
4.
2 Straight
Coolant Hole Rod (RS) H.B. produces all of the standard RS sizes
of 2 straight hole rod. Many of these standard sizes are always
stocked on our shelves. We maintain a small quantity of "hard" 12.2"
long sticks for immediate shipment. Most of our stock is maintained in
the 'green' state, which allows us to cut it to your exact length
required. Using this option, you can eliminate the scrap associated
with unusable cut off ends.
5.
Helical Hole
Rod HB maintains a supply of popular sizes of 2 helical hole 30
degree rods made by
Arno Friedrichs - Germany.
We are also able to supply 3-hole helical and 40 degree rods, but with
longer lead times. Helical rods can also be ordered as "Specials" with
custom lengths and geometries.
Dies and Bushings
can be made with minimal grind stock leaving you less carbide to
remove; saving grinding wheel life and grinding time, thus increasing
your productivity.
Examples of
these products are:
- Wear
parts
- Seal
rings
- Wire
drawing dies
- Cold
headings dies
- Bushings
These Blanks
can include, but are not limited to:
- Multiple OD's
- Multiple ID's
- Chamfers (angles) between diameters
- Tapered ID
- Tapered OD
Special
extrusions can be beneficial to you when you have a part requiring a
common cross section smaller than .750" OD. Shapes such as round,
square, or rectangular with or without thru holes can be processed
easily. In fact, we will build our own special tooling to produce the
finished product you are looking for. And, after extrusion we are
capable of adding additional preforming operations, such as centers,
chamfers, or any other geometry required.
HB is one of the
few companies in the country that manufactures these special products.
These special extruded shapes can be stocked in your required
geometries. HB will meet your special needs for extruded shapes.
Most flat blanks
are not stocked. They are made to your specific needs and, therefore,
will be supplied with minimal grindstock which will increase your
productivity.
All H.B. Carbide EDM blanks are guaranteed against
cracking.
Preforms for
Flat Blanks can include the following features:
- Chamfers
- Thru
holes for wire starting
- Holes for arbors in saw blanks and washers
- Angles
- Sharpening angles on OD of saw blanks
