Toolholders & Workholding

Just one wrong swivel and it's done: The touch probe collides badly with the workpiece or the chuck. To ensure that such a collision no longer leads to a prolonged machine standstill, HEIDENHAIN offers the TS 642, a universal replacement for the touch probes of HEIDENHAIN's TS 6xx series.

Hwacheon Machinery America Inc. introduces the C1 multiple-process turning center. Half turning center, half machining center (Y- and C-axis control), the C1 can completely manufacture parts with complicated shapes in a single chucking operation.

Based on the MD90 series, the Cameron Model 904 is specifically designed to turn any standard mill that accepts ¾" tooling into a high-precision micromachining center.

Fives offers the Landis-Bryant RU2 Fuel MGMT grinder. This high-precision grinding technology incorporates a modular multiple-surface grinder with extended flexibility to grind most complex components for fuel systems, valve and drive trains, bearings, aerospace and medical applications.

J.W. Winco Inc. offers GN 437 zinc die-cast adjustable friction hinges. The RoHS-compliant hinge body is zinc die-cast, with either a black powder coated, textured finish or silver powder coated, textured finish.

Northfield Precision Instrument Corp. introduces its customized Model 650 chuck. This chuck has been engineered using one chuck and two sets of flexing jaws.

The general-purpose drill line from Dormer Pramet includes the Precision Twist Drill brand of Silver & Deming drills. These reduced-shank drills deliver versatility and reliability.

Tsudakoma has developed the new RDS series direct-drive rotary tables. This series utilizes Tsudakoma's proprietary direct-drive motor system, enabling the rotary table to achieve high speed and acceleration with no backlash.

Overheated cutting edges cause chip welding, tool chipping and ultimately decreased tool life. To compensate, operators frequently reduce spindle speeds or increase their consumption of cutting tools. Both options prove inefficient, as machining takes longer and the expense of constantly replacing dull tools can drain your bank account. The HAIMER Cool Flash system, based on the existing Cool Jet system for shrink-fit holders, was designed to guarantee an optimal coolant supply, even at the highest spindle speed, according to the company.

Northfield Precision Instrument Corp. introduces its new Model 620 chuck. This 6"-dia. 3-jaw chuck has a 1"-dia. counterbore (hidden), with special sub-jaws, inserts and side loading base stop and stop pad.

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.

Techniks magnetic chucks are a fast workholding solution that reduces mold setup and/or changeover time by 50 percent, and allows machining on five sides. Use magnetic workholding for all types of milling, drilling, through-hole drilling and boring operations on all sizes of molds or other workpieces.
