Manufacturing miniature parts and features is not new. In the past, EDM and laser technologies were used to create these features. Although these technologies worked for low volume jobs, they are not practical for the high volume micro applications that are in demand today.

BIG DAISHOWA introduces a series of new micro engraving cutters developed and built by their partner SPHINX (Derendingen, Switzerland).

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 newest addition to its SPHINX micro drill line. The new drill, made of fine-grained solid carbide, delivers exceptional tool life and consistent process reliability.

Here are some insights into the extra care and know-how needed to achieve success and build a successful reputation as a reliable supplier of micro machined parts.

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.

This new micro deep-hole drill from BIG DAISHOWA’s Sphinx line provides a time-saving option for creating wire EDM starter holes, averaging 5X faster per hole according to testing.

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.

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

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

The MEGA Micro Coolant Nut provides precise coolant supply to micro cutting tool applications at high speeds.

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.

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.

Tool holders play a critical role in connecting elements maximizing machining performance, however, several different styles are available and the most suitable one will depend on the operation.
