What new technologies are there for turning and milling tools?
Using good tools in CNC machining is a crucial condition

"A good horse with a good saddle" is known to everyone, and the use of good tools in CNC machining is a crucial condition. In the ever-changing world of machining, tool manufacturers are constantly introducing innovative cutting tools and solutions.SandvikAs a benchmark enterprise in the tool industry, what new tool technologies have Coloman recently released? Learn about these new technologies that can help improve your mill's machining skills, and today we will introduce you to some of the new Sandvik Coroman tools.

 

OneNew insert material for steel turning
GC4425 and GC4415
The new generation of steel turning insert grades GC4425 and GC4415 brings a comprehensive performance improvement. A new matrix with good toughness and plastic deformation resistance, providing excellent reliability; The new post-processing process improves the intermittent cutting performance and avoids sudden blade breakage. The second generation of Inveio® coating technology provides more consistent performance, significantly improving wear resistance and extending tool life; With an average of 25% longer tool life, it is highly reliable and predictable, minimizing waste of insert and workpiece material.
Apply:
• Low alloy and unalloyed steels
• Suitable for high-volume production
• Outer and inner circle turning
• Roughing and finishing, continuous and light load intermittent cutting
TwoRound blade with rail interfaceCoroTurn® 107

A new rail interface is now available for round blades and tool holders. With fixed insert indexing, you can ensure that the insert is indexed in the same way every time and improve the quality and productivity of profiling and cavity machining processes. The new CBN platform features screw-mounted blades and up to 12 blade indexes available, which will increase productivity in heat-resistant superalloy materials.

Features and Benefits:
• Fixed insert indexing standardizes machining methods and indexing repeatability
• The rail interface locks the rotation of the blade, minimizing unnecessary stops due to blade or screw breakage
• Tool holder with upper and lower coolant for good chip control and high machining safety
• New geometries and material chains provide chip control over a wide range of applications, including finishing and non-linear turning
apply
• External and internal profile cutting
• Suitable for nonlinear methods (e.g. dynamic turning and cycloidal turning) to optimize cavity machining
• Finished in heat-resistant superalloy parts with a relatively open characteristic
ThreeNew materials for small diameter inner circle turningCoroTurn® XS GC1125
The CoroTurn® XS fine sharpening tool is now available for GC1125 grades. This means that higher masses can be achieved for very small internal circle features. The stable performance of the GC1125 will extend tool life or allow for higher cutting parameters for higher productivity.
Features and Benefits:
• High-quality grinding tools ensure high precision and repeatability
• Stability for all workpiece materials, reducing unplanned machine downtime
• PVD material provides good edge safety and excellent wear resistance when machining viscous materials
• Optimized coating process for longer tool life or increased productivity
apply
• High-quality internal turning of small parts
• For holes with a diameter of 2.7-7.2 mm
• Finishing and semi-finishing applications
• Designed for light load cutting parameters
• Cutting depth: 0.05–0.6 mm
• Feed: 0.01–0.05 mm/r
4. Solid carbide for titanium alloy cavity machiningEnd mills
CoroMill® Plura HFS ISO S 5×Dc 

The CoroMill® Plura HFS 5×D is a new carbide end mill designed for titanium cavity machining with tool lengths up to 5 times the diameter. With its innovative "shape control" design, end mills are ideal for stable machining of tall and thin walls without bending, while still achieving excellent surface quality.

 

Innovative features

• Innovative patented geometry with helix angle depending on the depth of cut

• Tapered core for increased tool rigidity

• Corner radius for titanium machining

• Unequal pitch for high speeds (up to 230 m/min)

• Equipped with 1745 material to optimize the roughing of titanium alloys

• Axial bore coolant and chip breaker for safe chip evacuation

 

Why choose CoroMill® Plura HFS 5×D?

• With lengths up to 5 times the diameter, this end mill can machine grooves in a single high-feed side milling step while avoiding misalignment, saving time and increasing productivity

• The "shape control" design ensures reduced bending, maximum stability and excellent surface quality for improved machining safety and tool life

• One integral end mill for both roughing and finishing can reduce inventory footprint Innovative features

• Innovative patented geometry with helix angle depending on the depth of cut

 

5. Integral end mills for heat-resistant superalloy plunge milling
CoroMill® Plura Gannet

The CoroMill® Plura Gannet is a monolithic end mill developed specifically for slot milling in heat-resistant superalloys. This end mill is part of Sandvik's Coromant-specific product range and is ideal for heat-resistant superalloy aerospace monolithic blades that are roughed using plunge milling. End mills equipped with excellent wear-resistant 1610 material have high process safety and long tool life.

Designed for plunging and milling

• Robust, patented geometry specially designed for insert milling

• Equipped with 1610 material, optimized insert milling of heat-resistant superalloys

• Cooling grooves on the tool handle for safe chip evacuation

• Provides excellent deformation control

• Delivers superior productivity and tool life

 

High productivity can be achieved in rough materials

• Unique solution for high productivity of parts with closed slots (e.g. closed monolithic blade grooves).

• Extremely high productivity due to the ability to cut large depths of cut in a limited time

• Since the force direction is axial, the self-stabilization effect is optimized

• Balanced anterior slot with ae = 30% ×DC

• Long overhang machining is possible, specifically designed for plunge milling
