Telford-based Vargus UK
has launched the new ST-Cut line of cutting tools for small part machining. Developed specifically for the turning of small components on Swiss-type sliding head turning centres, the range presents a solution for virtually every small part-turning application.
The ST-Cut series features a unique insert replacement system that provides fast and easy changeovers of inserts from both sides of the tool. This is particularly suitable for manufacturers with sliding head lathes where space is often limited inside the working envelope.
Also, the innovative clamping system demonstrates high repeatability and excellent rigidity for manufacturers aiming to part-off components with a maximum parting-off diameter of 17mm.
The ST-Cut line encompasses everything from parting-off, groove-turn, square grooving, round grooving, threading, front- and back-turning as well as face grooving. It incorporates both left- and right-hand inserts with a cutting width from 0.5 to 2mm with a range of cutting depths, geometries and insert grades.
Similarly, the square grooving/turn and round grooving line offers left and right-hand variants with insert widths from 0.5 to 3mm with the round groove inserts offering a choice of radii from 0.2, 0.5, 0.75, 1, 1.25 and 1.5mm. From a threading perspective, the left and right-hand inserts are supplied with a 55deg and 60deg profile option with a maximum insert width of up to 3.2mm.
Futhermore, the inserts are available in two grades, this includes the AlTiN PVD-coated VPG grade for achieving medium to high cutting speeds on alloy steel, stainless and titanium alloys. Sharper cutting edge
Alongside this, the uncoated VS020 sub-micro grade is recommended for medium to low cutting speeds. It is uncoated to ensure a sharper cutting edge that is crucial for very small components where accuracy is paramount.
To cater for the diverse demands of small part turning companies, Vargus has introduced the ST-Cut Series with a choice of tool holders that include square shank tool holders, step square shank tool holders and square shanks with 90deg tools.
The square shank tools are available in both left and right-hand variants with an adjusting screw, key and torque limiting adapter.
The tool shanks that accommodate the various insert geometries are available as an 8 x 10mm variant as well as a 10, 12, 16 and 20mm square shank with an overall length of either 110 or 120mm. Alongside the square shank, tools are the stepped square shank tool holders.
Also available in 8 x 10mm, 10, 12 and 16mm square shanks, the stepped tool holders offer a step of 30 or 40mm to provide the end-user with additional reach when cutting features in intricate parts or attaining access to difficult to reach areas.
Completing the line-up of tool holders is the square shank 90deg right-hand tool body. Vargus provides it with the option of a 10 or 12mm square shank that is 110 and 120mm long for the respective tool widths.
As well as the ST-Cut line, Vargus UK can also offer its VG-Cut series of parting-off solutions with chip formers and high-pressure coolant, its Microscope range for small boring applications and the GrooVical series for precision grooving.
