Chucks

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.

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.

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.

Northfield Precision Instrument Corp. introduces its new safety air reservoir tank. Its purpose is to feed an air chuck with a reserved air supply should you encounter a loss of shop air. This system can keep a chuck in the clamped position for up to 20 minutes, depending on conditions.

Reversible hard jaws from Dillon Manufacturing Inc., which are suitable for ID and OD workholding, can reportedly decrease the time and cost of tool setups, yet still accurately grip and locate workpieces. The jaws hold a specific range of part sizes and are usually used for first operation workholding.

The smallest clamping range yet from BIG Daishowa is the Super Slim 3S hydraulic chuck is intended for extremely repeatable high-precision microdrilling and microendmilling in the most challenging work envelopes thanks to its slim nose and tapered body.

MAPAL has expanded its program of narrow-contour HTC (High-Torque Chuck) clamping chucks, whose narrow shapes are produced without a restrictive brazed joint thanks to additive manufacturing. These new chucks can directly clamp diameters of 3, 4 and 5 mm, also allowing hydraulic clamping chucks to be used on the microscale, for example in medical technology or the timepiece and jewelry industry.

BIG KAISER introduces the Mega Perfect Grip from BIG Daishowa, a simple to handle, heavy-duty milling chuck for heat-resistant superalloys (HRSA) that eliminates endmill pullout under heavy torque loads. For manufacturers using milling chucks, pullout is a major issue, particularly when machining HRSAs, such as titanium or Inconel.

Emuge Corp., in partnership with Albrecht Precision Chucks, has introduced Emuge FPC mill/drill chucks that reportedly provide unprecedented rigidity, vibration damping, concentricity, machining speed and tool life versus conventional chuck technologies for milling and drilling applications.
