GIMT – Grooving and Turning Inserts with a New Advanced Chipformer


Highlights
  • New GIMT Groove-Turn chipformer for cut-grip pressed insert
  • Optimized for 4 applications: Grooving, Partial Grooving, Turning and Finish Turning
  • Standard widths 3, 4,5 & 6 mm


Groove-Turn inserts are used in four different applications:Full Width Grooving, Partial (finish) Grooving, Finish Turning, Turning

Most of the chipformers available in the market perform well in one or two of the above-mentioned four applications, but very rarely in all of them.

Based on ISCAR’s accumulated experience and intensive R&D, a unique GIMT insert with a new chipformer has been designed that excels in all four applications, providing efficient chip control in a wide range of machining conditions. The GIMT inserts were optimized for steel materials but they also function very well on stainless steel and high temperature material groups. The GIMT inserts are available in standard widths of 3, 4, 5 and 6 mm.

The new inserts provide a high-performance and cost-effective solution, which can eliminate the use of different insert types for each application, reduce stock requirements, and provide end users with higher flexibility.

 
Full Width Grooving
Partial (finish) Grooving


Finish Turning
Turning


Side turning land with constantly varying rake angle for better chip formation
Deflector with a wavy contour
Optimized radius area for excellent chip control in small ap for both partial grooving and finish turning
“F” style frontal deflector for improved chip control in full width grooving (5, 6 mm width only)
Variable width in the frontal land for earlier chip control at low feed rates
