Part-off and groove in the 'dry'
Advanced Carbide Tooling has introduced Futura-coated carbide inserts for its 2.2 parting-off and grooving system, allowing dry machining as well as higher cutting speeds.
Largest range of parting-off and grooving tools
A claim that its Mircona parting-off and grooving tools is the largest single range currently available from any manufacturer is being made by the UK supplier Advanced Carbide Tooling
One application requires 4.95mm diameter bar in 316L stainless steel to be parted off after machining, which is now performed with Microcut RHSS-1010 tooling.
The toolholder has a 10mm square shank, and the inserts used are 1.1mm wide and produced from TiN-coated ASP.
2060 high-speed steel, to ensure successful performance on difficult materials at low surface speeds.
They are held in a dove-tail recess in the toolholder and against a fixed back-stop.
On the first production run the company parted-off 2500 components in six hours with a single insert - a cutting time of nearly six hours.
More recently one insert parted-off 4000 components, achieving a cutting life of over nine hours.
Each cut takes about eight seconds and includes forming a 450 chamfer.
A high-quality surface finish is achieved, so no secondary operation is needed.
The work is performed with the bar rotating at 1100 rpm (17.3m/min) and with an initial feed rate of 0.025 mm/rev, followed by 0.015 mm/rev for the final 0.5mm.
"Increasing productivity is essential for the future success of the company, so tooling that can perform consistently for a whole shift is extremely useful," said production engineer Iain Connacher.
