BIG DAISHOWA’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.

The high-precision MEGA ER Grip with the modular CKB connection is now offered, allowing custom collet chuck configurations with standard components.

BIG DAISHOWA has introduced MEGA ER Grip, a new premium ER collet chuck system featuring the best runout accuracy in the industry: .00012" (3 microns) at 5xD.

MEGA New Baby Chuck is now available up to ø1" clamping for drills, reamers and finishing end mills with .00004" runout accuracy.

BIG DAISHOWA introduces the Mega Perfect Grip, a simple to handle, heavy-duty milling chuck for heat resistant super alloys (HRSA) that eliminates end mill pullout under heavy torque loads.

BIG DAISHOWA has announces addition to the MEGA DOUBLE POWER CHUCK lineup for heavy-duty end milling.

To make their cars as light and aerodynamic as possible, Team Penske’s shop performs delicate work milling aluminum, titanium and steel.

There are three particularly sensitive areas of the tool holder assembly that can experience process-affecting wear and tear and cause a cycle to change.

Bicycles are one of the oldest modes of transportation, but that doesn’t mean they haven’t evolved with the times.

Micromachining, cutting where the volume of chips produced with each tool path is very small, is not a high-speed operation in relation to chip load per tooth. Rather, it involves a high spindle speed due to cutter diameter. The part may be physically larger, but details of the part require ultra-small profiles achieved only by micromachining. In other words, micromachining is not limited in scope to only miniature parts.

When that inevitable job arises that requires higher RPM output, operators are left with the choice of replacing the machine altogether to gain higher productivity, or looking into an attachment, like a spindle speeder, to close the RPM gap.

Many machine shops lack objective criteria for making toolholder purchasing decisions & most are made by price alone. However they can improve runout significantly by using the right toolholders.

The chances of a tool slipping or pulling out in its holder during work is increasing. Here are some insights to help you select the proper holder for your work.

Otto Martin Maschinenbau GmbH & Co. KG has been manufacturing woodworking machinery since 1922. They know a thing or two about precision tools.
