Chucks

SCHUNK says the intelligent jaw design of the SCHUNK UVB-HS soft chuck jaws defines a new class of efficiency in lathe chuck technology. With a combination of overheight and angle cutting, it achieves a whole bundle of efficiency effects during finish machining of workpieces.

Following last year’s launch of PrimeTurning methodology and tools for external turning operations, Sandvik Coromant is introducing a dedicated CoroTurn Prime SL head that makes this process available for internal turning operations. The new SL head will meet the needs of oil and gas, aerospace and other manufacturers that machine diameters in excess of 90 mm (3.5 inches) and overhangs up to 8–10×D.

The highly versatile 13- inch engine lathe from Palmgren has the power to remove heavy metal and the accuracy and control for precision fine-tolerance tuning. The headstock is designed to provide maximum power for roughing cuts and smooth and quiet power for fine finishing.

Reaching deep inside a workpiece to drill holes can be a real bear. You’ve tried taper length and aircraft drills, but even those made of solid carbide are apt to wander when hanging out of the chuck unsupported.

Dillon Chuck Jaws introduces an 18”-dia. boring ring. Its relatively light weight allows customers the same ease boring out 18”-dia. blank top jaws as is had when forming smaller diameters using the smaller boring rings.

The idea of designing drills for higher feed rates by adding a third cutting edge is nothing new. However, due to the challenging chip evacuation, these tools have so far only been suitable for a few applications, such as machining cast iron. With a new design, the Hoffmann Group has now succeeded in harnessing the advantages of the three-flute drill for long-chipping steels and stainless steel materials.

In many technical fields, ultrafine grinding is one of the tasks that gives the product its final polish – in the truest sense of the word. This applies equally to both precision and the visual appeal. SUHNER offers an innovative grinding, milling and polishing system, SUNmic 60.
