Getting Micro Tuff with Miniature carbide drilling

"The pursuit of productivity when applying microdrills (tools less than 0.125" diameter) may be as much creative as it is scientific. The characteristics of the drill itself, machining parameters, hole depth, setup integrity and workpiece composition play delicately intertwined roles.

As a drill gets longer, relative to its diameter, its tendency to bend…

The New One-Lok Single Station CNC Vise

The new One-Lok CNC Vise is an evolution in workholding. The design of every other vise on the market today is based on 1950s knee mill technology, but, as every machinist knows, CNC milling is a completely different work environment.

The One-Lok was created from the ground up by Chick for use in CNC milling. Its unique design makes it possible to capture dramatic improvements in speed, precision, and versatility.  The following highlights some of the key differences between knee mill…

Some considerations when Drilling Cast Iron

As you already know, Cast Iron comes in a wide variety of types with an equally wide range of tensile strengths. Some of the common types are white cast, gray cast, malleable cast, and ductile or nodular cast. These materials also have a wide range of tensile strengths often ranging from 20Ksi to 60Ksi. Therefore, drill selection is important to maximize performance and…

A Thread ring GO gage checks the maximum minor diameter and the maximum pitch diameter size in a part, the NOGO checks for the part not to exceed the minimum pitch diameter size on a part. Basically there are three types of gages on the market: Solid Thread Rings, AGD Thread Rings and "Southern Style" Rings.

One of the premiere manufacturers of thread and ring gages is Glastonbury Southern Gage which was formed in 1995 when two of…

To Vend or not to Vend in your Tool Crib

"Vending machines have been around in some capacity since the late 1900s; they’ve dispensed everything from post cards to holy water to live bait. The business model is a sound one. An owner can set up a machine in a high traffic area stocked with goods people are likely to need and then customers can simply serve themselves their desired merchandise, be that candy bars or live worms. What role then do vending machines play in an industrial setting? How and why can industrial vending…
