TaeguTec Thailand unveils new turning chip breakers and grades in the turning TOPMINI line for Swiss type automatic lathes that can be applied to various materials and cutting ranges.

When machining small components in Swiss type automatic lathes, longer tool life, excellent surface roughness and good chip control are required under low machining conditions. In addition, when processing a variety of workpiece materials, an integrated grade is required without the need of grade replacement. In line with these demands, TaeguTec has developed new PVD coating grades and new chip breakers that can be applied to various materials and cutting ranges. 

The SL chip breaker for super finishing has excellent chip control in areas with a low depth of 0.25 mm or less, minimizing chip control problems during machining.

The general purpose SM chip breaker has a low cutting force and good chip control in a wide area with a cutting depth of less than 1.5 mm. It ensures good surface finish and dimensional precision. 

The SH chip breaker has a wide groove width, which is particularly suitable for processing automotive parts and has a low cutting force and good machining quality even at a maximum cutting depth of 3.5 mm. In addition, the line offers the “– F” type with a sharp edge that generates excellent surface finish due to the low cutting force, and the “– E” type with micro honing that prevents chipping during operation ensuring stable and longer tool life.

The new PVD coating grades TT4410 and TT4430 implement excellent wear resistance, longer tool life, as well as good surface finish and dimensional precision in various materials of small component machining under low cutting speed and feed. This is due to its superfine substrate, good coating adhesion, specialized coating layer that prevents coating peeling, improved chipping resistance and ground surface.

TT4410 grade features

• High wear resistant micro-alloy substrate with  excellent ground surface
• Multi AlTiCrN coating layer with improved bonding  on substrate and anti-adhesion of workpiece material 
• Suitable for steel, stainless steel, heat-resistant super alloy and Ti-alloy in high-speed
•  continuous cutting Suitable for hardened steel in low-speed continuous cutting
• Dark brown color

TT4430 grade features

• High toughened micro-alloy
• Multi AlTiCrN coating layer with stabilized edge, anti-adhesion of workpiece material and high chipping resistance 
• Suitable for steel, stainless steel, heat-resistant super alloy and Ti-alloy in low-medium speed continuous cutting and light interrupted cutting
• Dark brown color
