Mate Precision Machinable Hard Jaws Hold Complex Part Geometry

Mate Precision Technologies showcases its custom machinable hard jaws for all sizes of its DynoGrip workholding vises, available in center and movable configurations. The jaws feature Mate’s quick-change design, but are blank for adding a custom profile. Customers can modify the machinable hard jaws themselves or Mate can add the custom jaw profile before it ships. The company says it is able to deliver most custom jaw profiles in 10 days or less.

The machinable hard jaws are made from the same hardened tool steel as Mate’s standard jaws, with the same core hardness of 45-50 HRC and surface hardness of up to 65 HRC. They handle complex geometries typically associated with soft jaws, but with increased rigidity and hardness. Mate’s machinable hard jaws are also available as center jaws to double the capacity while holding parts with complex geometries.

According to the company, there are numerous possibilities for modifying Mate’s machinable hard jaws to fit special geometries. For example, Mate can modify jaws to accommodate custom dovetails or Picatinny rail dovetails. Other custom solutions include jaws for holding round parts, V-shaped jaws with teeth and inserts for clamping bars on top of the jaws. The machinable hard jaws are tailored to hold complex part geometry during finishing operations.

Mate is also highlighting its 52/96 workholding system. It is engineered to maximize holding power for three-, four- and five-axis machining centers and consists of DynoLock bases, DynoGrip vises and DynoMount mounts. The workholding system is said to reduce setup times and process variability while optimizing accuracy and repeatability in a compact, quick-change, modular design.
