Tungaloy has added 37 left-hand inserts to the TCS18 and TCL18 insert lines of the TetraMiniCut grooving and parting tool series.
Featuring parting and grooving inserts with four economical cutting edges, TetraMiniCut offers a unique insert clamping method that ensures secure retention and high edge repeatability, promising machining accuracy and tool life predictability.
The series is now introducing TCS18 and TCL18 inserts designed for left-hand cuts, expanding the product lines that, up to now, has offered right-hand inserts only. Grooving and parting tools commonly used in most of the operations performed in conventional CNC lathes and Swiss machines are right-handed. As highly advanced multitasking machines with multiple spindles and turrets are gaining popularity to maximize productivity, the needs for left-hand tools are increasing as well, which enable simultaneous machining on the right and left-hand spindles of such machines.
TetraMiniCut’s TCS18 and TCL18 geometries feature pressed-to-form 3D chipbreaker that provide superior chip control. TCS18 incorporates four cutting edges with an optimal rake angle that provides the cutting edge with a good balance of strength and sharpness. TCL18 has cutting edges with a large rake angle that generates light cutting action and reduced cutting load for machining stability.
With this expansion, TetraMiniCut left-hand tooling can now be purchased off the shelf at less costs, while allowing more end users to use the full capabilities of TetraMiniCut’s tool stability and accurate edge repeatability and maximum productivity over an expanded range of grooving and parting operations.
Related Glossary Terms
- chipbreaker
chipbreaker
Groove or other tool geometry that breaks chips into small fragments as they come off the workpiece. Designed to prevent chips from becoming so long that they are difficult to control, catch in turning parts and cause safety problems.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- grooving
grooving
Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.
- multifunction machines ( multitasking machines)
multifunction machines ( multitasking machines)
Machines and machining/turning centers capable of performing a variety of tasks, including milling, drilling, grinding boring, turning and cutoff, usually in just one setup.
- parting
parting
When used in lathe or screw-machine operations, this process separates a completed part from chuck-held or collet-fed stock by means of a very narrow, flat-end cutting, or parting, tool.
- rake
rake
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
