Turning - Technical Information
The insert type and size are determined by the toolholder choice. The code on the insert must correspond with the code on the toolholder. The size of the insert is one of the factors that determines the maximum cutting depth (other factors are setting angle, nose radius and chipbreaker). Use the table on next page as a guideline to choose insert size.

Turning - Technical information
The choice of nose radius is dependent on the workpiece design and the machining operation. The nose radius influences cutting data choice and the surface finish achieved. The maximum feed rate that can be used depends on a number of factors including machine power, stability, workpiece material, insert shape and size, nose radius, chipbreaker, grade and setting angle.
Small nose radius = universal machining, low cutting forces (less vibration risk). Large nose radius = strong, suitable for high cutting data, good surface finish.

Turning - Secolor 
Secolor is a system for selection of chipbreaker and grade. It is based on a matrix with nine squares symbolizing different workpiece materials and different machining conditions. The actual workpiece material (steel, stainless steel or cast iron) and the actual application (finishing, medium roughing or roughing) will lead to a recommendation of a chipbreaker and a grade.
The Secolor system is also used on the insert boxes. Black dots in the matrix indicate main application areas for the inserts. Circles indicate alternative application areas.
For more information about chipbreakers and the Seco chipbreaker program see pages 28-34. For more information about grades and the Seco range see pages 35-39.
Chipbreaker and grade
Finishing at low depth of cut Typical ap = .008–.032 and f = .008 in/rev.
Medium-rough machining Typical one pass machining at ap = .032–.120 and f = .012 in/rev.
Rough machining at higher depth of cut and feed rate In most cases with difficult surface conditions such as scale, irregularities and other conditions leading to interruptions and edge damage. Typically ap = .12–.28 and f = .02 in/rev.

Turning - Chipbreakers
The chipbreakers are designed to control the chips when turning long chipping materials. The chipbreaker designations describe the application area as follows:

Optimization – Grades
Insert Wear – Failure Modes
1. NORMAL FLANK WEAR Normal Flank Wear, since it is predictable and dependable, is the most desirable wear condition. Rapid flank wear looks the same, but happens much quicker than the target 15 minutes of time in cut.
CAUSE Abrasive wear. Hard microscopic inclusions of carbide or work-hardened material in the workpiece cut into the insert. Small pieces of coating break off and cut into the insert. The cobalt eventually wears out of the matrix, the carbide grains no longer have sufficient adhesion, and they break off.
WHAT TO LOOK FOR • Relatively uniform abrasion along the cutting edge • Occasionally, metal from the workpiece that is smeared over the cutting edge can exaggerate the apparent size of the wear scar • Duratomic inserts will wear black and smooth • Non-Duratomic inserts will have shiny abrasions • An all black condition is the under-coating showing through the top coating
WHEN TO EXPECT IT • In all materials, an insert will fail due to normal wear if it doesn’t fail from something else first.
CORRECTIVE ACTIONS (TO RAPID FLANK WEAR) • Select a more wear resistant, harder, or coated carbide grade • Reduce the cutting speed (RPM or SFPM) • Apply coolant correctly
2. CRATERING CAUSE A combination of diffusion, decomposition and abrasive wear causes cratering. The heat from workpiece chips decomposes the tungsten carbide grains in the substrate, and carbon leaches into the chips (diffusion), wearing a ‘crater’ on the top of the insert. The crater will eventually grow large enough to cause the insert flank to chip, or may cause rapid flank wear.
WHAT TO LOOK FOR • Craters or pits on top of inserts • Chipbreaking may improve after cratering starts
WHEN TO EXPECT IT • Iron or titanium-based alloys
 
53
3. BUILT UP EDGE CAUSE Material adhesion. BUE is a result of the workpiece material being pressure welded to the cutting edge. This occurs when there is chemical affinity, high pressure, and sufficient temperature in the cutting zone. Eventually, the built up edge breaks off and takes pieces of the insert with it, leading to chippage and rapid flank wear.
WHAT TO LOOK FOR • Shiny material on the top or flank of the insert edge • Erratic changes in part size or finish
WHEN TO EXPECT IT • Gummy materials • At low speeds • High temp alloys and stainless steel • Threading operations • Drilling • Non-ferrous materials
CORRECTIVE ACTIONS • Any coating, especially a nitride coating, will reduce built-up edge • Increase the cutting speed (RPM or SFPM) • Select an insert with a sharper cutting edge geometry • Increase the feed rate • Apply coolant correctly, perhaps increasing the concentration • Use an insert with a smoother (polished) surface
4. CHIPPING
f = vibration frequency (cycles per second)
V = cutting speed (feet per minute)
WL = wave length of vibration (inches)
CAUSE Mechanical instability. Chipping of the insert edge is often a result of vibrations in the workpiece or spindle. Hard inclusions in the surface of the material being cut and interrupted cuts result in local stress concentrations that can cause chipping.
WHAT TO LOOK FOR • Chips along the edge of the insert
WHEN TO EXPECT IT • Non-rigid set-ups (bad bearings, worn spindles, etc.) • Hard spots in work material • Powdered Metal (PM) materials
CORRECTIVE ACTIONS • Ensure proper (rigid) machine tool setup • Minimize deflection • Select a tougher insert grade • Select a stronger cutting edge geometry • Reduce the feed rate (especially at the entrance or exit of the cut) • Use honed inserts • See also corrective actions for built-up edge
Insert Wear – Failure Modes
54
5. THERMAL MECHANICAL FAILURE CAUSE A combination of Thermal Cycling (changing the temperature of the insert very rapidly), Thermal Load (temperature differences between warm and cold zones), and Mechanical Shock causes thermal mechanical failure. Stress cracks form along the insert edge, eventually causing sections of carbide to pull out and appear to be chipping. Seen most commonly in milling.
WHAT TO LOOK FOR • Multiple cracks perpendicular to cutting edge • Need to identify before chipping
WHEN TO EXPECT IT • Milling • Facing operations when a large number of parts are machined • Operations with intermittent coolant flow
CORRECTIVE ACTIONS • Apply coolant correctly or remove completely • Select a tougher insert grade (higher cobalt content) • Reduce the cutting speed (RPM or SFPM) • Reduce the feed rate • Use a freer cutting geometry to reduce heat
6. EDGE DEFORMATION CAUSE Thermal Overloading. Excessive heat causes the carbide binder (cobalt) to soften. Mechanical Overloading. Pressure of the insert against the workpiece makes the insert deform or sag at the tip, eventually breaking off or leading to rapid flank wear.
WHAT TO LOOK FOR • Deformation at the cutting edge • The dimensions of the workpiece may not be as expected
WHEN TO EXPECT IT • High heat operations • High speed • Hard steels or work-hardened surfaces • High temperature alloys • High feed rates
CORRECTIVE ACTIONS • Apply coolant correctly • Use a harder, more wear resistant grade • Reduce cutting speed (RPM or SFPM) • Reduce the feed rate • Select an insert with a larger nose radius. • Using a freer cutting insert geometry will have a small but positive effect
Insert Wear – Failure Modes
55
7. NOTCHING CAUSE Differences in hardness or abrasiveness within the workpiece. Notching is caused when the surface of the workpiece is harder or more abrasive than the material deeper in the cut, e.g. surface hardening from previous cuts, forged or cast surfaces, or surface scale. This causes the insert to wear more rapidly in that part of the cutting zone. Local Stress Concentration can also lead to notching. As a result of the compressive stress along the cutting edge – and lack of the same behind the cutting edge – the insert is particularly stressed at the depth of cut line. Impact of any sort, such as hard micro inclusions in the workpiece material or slight interruptions, can cause a notch.
WHAT TO LOOK FOR • Notching or chipping at the depth of cut area on the insert
WHEN TO EXPECT IT • Materials with surface scale or oxidation • Work hardened materials • Cast or irregular surfaces • (see also Built Up Edge)
CORRECTIVE ACTIONS • Vary the depth of cut when using multiple passes • Use a tool with a larger lead angle • Reduce the feed rate • Increase cutting speed if machining a high temp alloy   • NOTE: This will generate more flank wear • Select a tougher insert grade • Carefully increase the hone in the DOC area • Use a chipbreaker designed for high feed rates • Prevent build-up edge, especially in stainless and high temp alloys
8. MECHANICAL FRACTURE CAUSE Excessive wear of any type can cause mechanical fracture. Mechanical overload. The mechanical load is so great that the insert breaks during the first moments of a cut.
WHAT TO LOOK FOR • Fracture of insert
CORRECTIVE ACTIONS • Correct for all other failure mechanisms besides normal flank wear • Reduce the feed rate • Reduce the depth of cut • Verify set-up rigidity • Select a tougher insert grade (higher content of cobalt) • Select an insert with a more secure cutting edge • Select an insert with a chipbreaker geometry for higher feed rates • Select a thicker insert • Check the workpiece for hard inclusions or difficult entry

Operation guidelines • The favorable surface finish results are
lost, if the cutting edge angle diverges from 95° (C-and W-style inserts).
• Max diversion allowed: ±2°.
• Back-turning is NOT recommended.
Copying with D- and T-style High Feed inserts
Since D- and T-style High Feed inserts not are designed within ISO-tolerances an adjust- ment in the tool offset must be made. A deviation from the nominal nose radius shape, will always occur (D1, D2) when going towards a corner.
The wiper on a D-and T-style insert does not provide an exact corner radius.
ISO-profile (Nominal Nose radius)
When copying with a D- or T-style High Feed insert, an adjustment must be made for dimensional deviations.
• The favorable surface finish results are lost, if the cutting edge angle diverges from 93° (D-and T-style inserts).
• Max diversion allowed: ±2°.
• Back-turning is NOT recommended.
Turning – High Feed inserts
C-style High Feed inserts
On C-style High Feed inserts, except for PCBN inserts, the wiper geometry is also located on the 100° corner.
Chipbreaker W-R4 and W-R7

The Helix™ wiper technology
SECOMAX™ Crossbill™ PCBN Wiper inserts A deviation from the normal radius shape will always occur when a standard wiper geometry is used to machine towards a corner/face. The new Crossbill™ Wiper gives the opportunity to produce a radius without deviation from the normal shape and without losing the advantages from a standard wiper insert.

Turning – High Feed inserts
Our unique patented, Helix™ wiper concept is designed for optimization in finish machining. It has a wiper on both sides of the corner radii (as the standard) but the protection chamfer is twisted from negative to positive or from positive to negative depending on the application. It is available in grade CBN050C. The following considerations apply when selecting the appropriate geometry:
Positive Wiper, WZP • Reducing vibrations in weak set-ups • Lower radial cutting forces • Used where standard wiper cannot be used
Negative Wiper, WZN • Longer tool life • Reducing vibrations in stable set-ups • Increasing compressive stresses

Turning – Small diameter boring
Seco offers a range of small diameter boring bars to machine holes as small as .180 inch. Inserts are available in C and T shapes in modern PVD coated inserts.
The toolholders are available in steel and also in heavy metal for applications
where extra reach or stability is needed.
Set-up information When positioned in the machine the insert will sit slightly above center line. This is a design feature of the tool that compensates for the deflection and improves the machining operation.
When setting the tool in the machine be sure to position it with the flat parallel and in the same plane as the bed of the machine.

SecomaxTM – PCBN
Introduction Polycrystalline Cubic Boron Nitride (PCBN) is a material which is sintered at extremely high pressure and high temperature into a wear-resistant material with properties close to those of diamond. Due to the hot hardness, oxidation resistance and fracture toughness of the material, inserts made of PCBN have excellent edge strength and long tool life in machining operations on hard fer- rous materials and pearlitic grey cast iron.
Secomax PCBN inserts are suitable for machining:
• Hardened steels (including hard-facing alloys) • Pearlitic grey cast iron • Chilled and white cast iron • Manganese steel • Cemented carbide • Valve seat materials • Powder metallurgy components • Nickel-based super alloys, e.g. Inconel 718
For more information including a comprehensive guide to understanding and applying PCBN successfully, please ask your sales representative for the ’Secomax PCBN, Technical Guide’.

The vast majority of heat treated components in the metal wor- king industry are machined to their final geometrical form after hardening. A new method in hard turning is now introduced, the Seco patented Plunge Turning. The plunging process consists of an orthogonal cut, using the solid CBN100.
Geometry recommendations Strong cutting edge geometries are always preferred.
• Negative cutting geometry • Chamfered cutting edge • Large nose radius
Sharp positive cutting edge geometry can be advantageous when:
• Finishing of small hardened bores without interruptions • Finishing of unstable components without interruptions • Finishing of pearlitic grey cast iron

Plunge Turning
Conventional Turning Plunge Turning
General cutting data recommendation for Plunge Turning is vc = 660–1300 sf/min and f = .0016 in/rev.
To avoid the cutting edge profile affecting surface finish, complete the operation with a small axial movement.
In addition to the introduction of the Plunge Turning method there are also some new toolholders. These toolholders have set screws which give the possibility to adjust the tool- holder to an exact setting angle. The toolholders (only available in metric sizes) have a designation ending with – PL, and are available for inserts in sizes T..2 and T..3.
Using the Plunge Turning method gives two great advantages compared to conventional hard turning, reduction in cutting time (up to 90%) and improved surface integrity.
