We have developed an "FB Breaker" for M-class positive insert
finishing and an "LB Breaker" for light turning that display excellent chip
control in processes ranging from finishing to light turning of low carbon steel
and general steel. The FB type went on sale in March 2014 and the LB type will
go on sale in November 2014.
Problems that can occur during turning of various low carbon steel
machine parts, such as car parts – particularly from the finishing process to
the light turning process – include difficulty in chip control, chip
entanglement with work materials and tools, a tendency for equipment to be shut
down or run idle because of temporary trouble, and a tendency for unsatisfactory
machined surfaces due to damage to work materials by chips.
The "FB Breaker/LB Breaker" resolves these issues and enables
machining in a stable fashion. Chip control of low carbon steel sheeting, in
particular, has been much improved over existing products, and this contributes
to efficiency improvements and cost reductions in processes ranging from
finishing to light turning.
1．Characteristics
-
(1)"FB Breaker" for finishing process
-
The insert rake angle (the cutting edge angle that influences cutting
resistance and chip separation) has been optimized in each position to increase
chip deformation, a steep breaker wall applied to the insert cutting edge
ensures the chip curling diameter is minimized, and excellent chip control is
displayed during processes in the low-cut depth, low-feed range. In addition, by
setting a large rake angle of 20° and using with a new cermet grade, the
appearance of machined surfaces can be greatly improved.
-
(2)"LB Breaker" for light turning
-
Chip separation is improved by means of a unique ridged breaker
configuration, and stable processing in the light turning range is
achieved.*1 In addition, sudden chipping of the
cutting edge during processes that momentarily place great load near the cutting
edge, such as stop boring, is prevented by a design that strengthens the region
near the cutting edge, extending the life of the tool.
