Chucks

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.

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.
