Toolholders & Workholding

The HAINBUCH SPANNTOP high-precision workholding system offers users the option of converting the basic chuck for OD, ID and 3-jaw clamping operations with a change-over time of 2 minutes or less. Equally important, in each mode, the chuck delivers proven performance and high repeatability, according to the company.

International Mold Steel Inc. announced the results of a study that showed reduced vibration with Toolox 44 (made by SSAB) toolholders. A recent study conducted at the KTH Royal Institute of Technology of Sweden, compared Toolox 44 with conventional tool steel alloyed with chromium, molybdenum and vanadium.

The REGO-FIX intRlox Mini Nut for Swiss automatic machine tool applications has an anti-slip locking design that is engineered to prevent the locking wrench from slipping off the nut during assembly and disassembly.

Carmex's quick-change polygon threading toolholders enable customers whose machines are equipped with the Sandvik Capto system to utilize Carmex's threading inserts. Incorporating a polygon taper to ensure automatic radial centering and even pressure around the coupling, the toolholders are ISO standard (26623) compliant for toolholding systems.

Jaw force gages from Dillon Manufacturing Inc. allow users to accurately measure the force applied to each chuck jaw independently, so problems can be diagnosed and corrected before a failure occurs. The reading in pounds of chucking force per jaw is the holding force available for that specific jaw.

Alfa Tools introduces tungsten carbide-tipped hole cutters for cutting many different types of materials, including construction steel plate, stainless steel, iron, aluminum, copper, cast iron, fiberglass and plastics.
