Chucks & Jaws

Sandvik Coromant has introduced a high-precision hydraulic chuck for turning operations that offers enhanced pull-out security. CoroChuck 935 has been designed to deliver fast, rigid and secure clamping, time after time.

Walter has introduced the Walter Prototyp ceramic milling cutters MC275/MC075. These two new tools deliver significantly increased productivity, cutting speeds and high metal-removal rates in the machining of nickel-based alloys.

Kurt DoveLock master jaws are designed to be installed in replacement of standard cap screw jaws and create a quick-change capability. Once the DoveLock master jaws are installed into the vise they perform as a receiver for the replaceable jaws and are installed or removed by loosening three quick clamps in the top of each master jaw.

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.

Dillon Manufacturing full-grip pie jaws made of 1018 CR steel are now available in diameters from 6 to 15 inches, with heights of 2, 4 and 6 inches. Constructed of 1018 CRS, these heat-treatable and weldable steel jaws allow for complete gripping of the workpiece to maintain accuracy.

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.

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.

With the new VM 9 modular turning machine, EMAG has introduced a platform that covers a broad spectrum of applications thanks to the combined turning, milling and drilling technologies and intelligent machine design. The highly accessible machining area and workpiece spindle fitted at the bottom ensure short tooling times and maximum flexibility in the production of workpieces in small series.
