BIG KAISER Adds Options to Mega ER Grip Collet Chuck Offering

May 19, 2017 11:48 am

Hoffman Estates, IL – BIG KAISER’s Mega ER Grip was designed to outperform all standard ER systems in the four most critical areas of tool holder performance: clamping force, concentricity, rigidity and balance at high spindle speeds. All Mega ER holders are now sold without a standard clamping nut so that customers can choose the best clamping nut option for their needs.

BIG KAISER has expanded the line to include more options of BIG-PLUS, specifically BBT30, BBT40 and BBT50 tapers. These tapers are available in standard configurations of ER11, ER16, ER20, ER25, and ER32 to optimize tool projection and rigidity.

There are four clamping nut options:

  1. Mega ER nut incorporates a ball bearing raceway and cylindrical outside diameter for the best performance, speed and accuracy. It is ideal for solid carbide drills and reamers.
  2. Mega ER solid nut has a surface treatment for friction reduction. It has a cylindrical outside diameter, but does not have a ball bearing raceway and has a special friction coating to help collet clamping.
  3. Standard ER nut has no coolant delivery system, no bearing nut and has surface treatment for friction reduction.
  4. Mega ER Perfect Seal system allows users to optimize coolant flow and can seal high- pressure coolant up to 7Mpa.

Aside from the Standard ER nut, the three other options require the exclusive MEGA wrench to clamp or unclamp the tool. A standard hook spanner wrench can be used on the Standard ER nut for clamping or unclamping, which works perfectly for economical uses.

All components of the Mega ER Grip system are manufactured with BIG Daishowa’s high-precision production technology. BIG KAISER’s Mega ER collets are made in accordance with DIN6499 and ISO15488 standards and feature the best runout accuracy in the world, hitting a guaranteed .00012” (3 microns) at 5xD. Additionally, by utilizing the Mega ER Perfect Seal, coolant can be securely delivered through-tool or directed to the cutter periphery.

These factors, combined with the system’s reliable and stable runout accuracy, contribute to improving machining capabilities and significant long-term savings.
