1、PCD and PCBN Tools for Rolls Machining
Moresuperhard solid CBN inserts and PCD tools for machining high hardness
rolls, cast iron roll, high-speed steel (HSS) roll, Ni-Cr alloy cast iron
roll, chilled cast iron roll, threaded steel roll, cast iron rolls, cast
steel rolls, tungsten carbide ring, forged steel cold Rolls. Due to its
excellent properties, carbide rolls are widely used in the steel industry
and their hardness is very high. For the machining of cemented carbide
rolls, CBN/PCD Inserts can effectively replace the grinding process to
improve production efficiency.
The roll is the main workpiece and tool that makes the metal continuously
plastically deform on the rolling mill. The roll is mainly composed of three
parts: roll body, roll neck and roll head. The roll is the intermediate part
of the roll that actually participates in rolling the metal. Has smooth
cylindrical or grooved surfaces. Rollers are almost universally used in
nearly every manufacturing process in the world. The roller is the main part
of the rolling machine, with the pressure which come from the rolling roller
to roll the steel.
1）There are many classification methods of rolls,
- The material of the roller have : cast steel roller, case iron roller,
forged roller.
- Product type, there are strip steel rolls, section steel rolls, wire rod
rolls
- Position of the rolls in the rolling mill series, there are billet rolls,
rough rolls, finishing rolls, etc.
- Product function, there are scale-breaking rollers, perforated rollers,
leveling rollers, etc.
- Product material, there are hot rolls, cold rolls, etc.
- Type of rolling mill, it is divided into flat rolls and grooved rolls (it
is used for rolling large, medium and small sections, wire rods and blooming
billets. Grooves are engraved on the roll surface to shape the rolling
stock), special roll
2）When processing mill rolls, especially processing large scale steel iron
roll, it often has irregular surface, sand inclusion, holes and other
problems. In order to solve the above problems we should choose What PCD and
PCBN Inserts for Turning Rolls ?
- The tools materials for machining rolls include pcd inserts, pcbn cutting
tools and solid cbn inserts, etc
- Solid CBN Insert is the hardest tool material for the processing ferrous
metal materials and is the preferred tool for heavy duty cutting rolls. The
high hardness rolls, Moresuperhard recommend the Solid CBN inserts which can
be used for large margin cutting. Compared with the carbide cutting tools,
the Solid CBN insert has performance stable, good production efficiency, and
low production costs. Tungsten carbide ring is also called tungsten carbide
alloy roll ring ( WC rolls or TC rolls), we process them with CBN and PCD
Tools .
- Normally, CBN Inserts are generally used for rough turning tungsten
carbide rolls which hardness ≤ HRA88. PCD Tools are mostly used for finish
turning cylinder, chamfering and engraving.
2、The specifications size of PCD tools, solid CBN inserts for machining
roll
- Solid CBN inserts for Rolls Machining
As a PCBN inserts manufacturer and exporter in China, More Superhard's PCBN
inserts have excellent performance in processing gray cast iron,nodular cast
iron,hardened steel and material, sintered metal,and processing work piece
surface is highly polished and very durable. Solid CBN iinserts rough
machining high Ni-Cr alloy cast iron rolls, semi finishing chilled cast iron
rolls, finish turning forged steel cold rolls, turning tungsten carbide
rings and hss rolls, etc
- PCD Notching Tools, PCD Boring Cutter for Roller
The PCD notching tools, pcd boring cutters are made by PCD blanks (E6)
brazing on the tungsten carbide body. Most common is full face pcd notching
tools. PCD boring tools are used for machining various of tungsten carbide
rollers. PCD tips for carbide roller notching.
When machining rolls, the grooving tool sometimes breaks, which is generally
due to the following reasons:
Reason1.The tool holder and tool head are not well matched, the accuracy is
not reached, and the tool is twisted during processing, resulting in tool
fracture.
Reason2.The strength of the tool holder is not enough, and the alloy matrix
of the PCD notching tools is too thin, so the strength and toughness are not
enough, leading to fracture in the process of use.
Reason3.Unconventional fracture, for example, the positioning surface of the
roller knife is not round, or there is a violent processing when processing.
For these reasons, we propose the following solutions:
Solution1.Control the precision of tool holder and tool head, pay attention
to step by step when processing
Solution2.Enhance the strength of the tool and increase the thickness of the
alloy matrix. If the customer has certain requirements for thickness, you
can make the diamond part as thin as possible, the alloy matrix thicker to
enhance the strength of the tool.
Solution3.The circular arc of the positioning surface of the PCD notching
tools should be rounded. Not violent processing, should step by step.
