The limitations of using milling tools to prepare holes for finishing become apparent as hole depth and volume increase. Enter the relatively simple and affordable twin cutter, which can solve this and virtually any other holemaking problem.

Moldmakers hoping to avoid problems such as chatter, poor tool life and molds that fail quality control muster need to consider a variety of factors when selecting a long-reach toolholder.

The is no general rule to cutting tool shank insertion as a multiplier for shank diameter. All tool holder types have different requirements.

BIG DAISHOWA expands jet-through hydraulic chuck line to include the BCV interface and additional inch sizes.

The EWA Automatic Fine Boring System performs closed-loop boring operations without a human operator.

The medical industry pushes the limits of precision for machining and tools. The trend toward less-invasive surgery using smaller parts translates to a need to better control the preci­sion and tolerances of micromachining processes.

Shrink-fit and hydraulic holders are both useful in low clearance, tight work envelopes found in moldmaking and multi-axis machining applications. When deciding which one to use, their differences will guide your choice. Here are some of the fundamental contrasts to help you decide which holder type is best for your work.

BIG DAISHOWA is introducing the RBX12 Air Power Spindle, a high-speed air-driven spindle that achieves an impressive variable rotational speed of 100,000-120,000 RPM.

Reducing the L:D ratio provides an improvement in speed which then provides longer tool life, better surface finish and size control of the bore.

Cleanliness is key to achieving good runout control when assembling tool holders. Small particles or oil in a tool holder can cause large runout of the cutting tool, deceasing tool life and performance.
