We where very excited to meet and greet many of our customers at the 2017 Western Tool & Supply Open House.
It was held at their San Jose, CA. on September 21- 22, 2017.
We featured quite a few featured products from our principals during the two day event. It was great discussing lots of technical applications that machinists brought to us!
We got to spend a few days in Chicago to get a great preview of some of the newest products and innovations for the kind of machining we do on the West Coast.
There's some really informative videos on quite number of the products so be sure and give yourself some time to watch them.
Use as a single or double station fixed jaw vise. Two vises for the price of one.
The small footprint allows for multiple units to be ganged together on vertical or horizontal machines.
BIG KAISER is continuing down the path of digital tooling innovation with the introduction of the EWD EVO, a digital boring head designed with a single goal in mind—making the life of an operator as easy as possible.
It will be synched with the new BIG KAISER smartphone and tablet app, which was developed to enhance user friendliness while assembling and running BIG KAISER boring tools.
Not only will you be able to read the cutting diameter change, but the app will also help operators determine optimal cutting parameters from their tool assemblies. The app will also log historical adjustments for all tools ever synched with it, a critical piece for shops joining the smart manufacturing movement.
Heimatec Inc. spotlighted its complete line of live tools and showcased them at IMTS in a series of four new catalogs. Already offering the most complete line of live tools available in the industry, with over 40,000 designs in its database,
Check out the video! Matt Saccomanno discusses the Microconic Workholding system at IMTS 2016.
Masa Tool has developed the Microconic™ system specifically for holding workpieces from Ø0.15mm to 10mm (Ø0.006" to 0.390") in any machine that has a collet-type chuck.
The Microconic™ system works with either draw-type or push-type standard collet systems that are in any machine.
The Over-grip collet capabilities of Masa Microconic™ System, introduces a whole new world of time saving opportunities awaiting. Our Overgrip Collets open up to 4mm (0.157") diameter larger than the clamping diameter.
Read this section or just watch the video! The SpinSelect Multi-Pocket Selectable Tool Holder was created to increase productivity and consistency by decreasing downtime associated with tool and insert setups and changovers.
Designed for use on most lathes having a turret or tool post, SpinSelect™ offers significantly better throughput on machining tasks such as heavy roughing, harder material removal, and short runs. Machining operators have seen up to an 85% savings on changeover/setup times as SpinSelect creates a nearly continuous runtime with offline insert changes/reloading.
The high speed turning of aluminium alloys and non-ferrous materials has now been taken to a new level with the introduction of the NTK PD2 insert line. With exceptional edge sharpness and adhesion resistance, the new PD2 range of inserts are ideal for extending tool life and productivity on difficult to machine alloys.
Furthermore, the edge toughness and composition give the PD2 tool life and consistency that is unrivalled when conducting interrupted and continuous machining.
The new PD2 is available as a positive insert with a CCMT, DCMT and TPMT geometry that provides a PCD cutting edge length of 2.3mm with the option of a 0.2 or 0.4mm corner radius. The various insert geometries and available with an insert thickness from 2.4 to 9.5mm.
Complementing the positive geometry inserts is a complete selection of negative type inserts for the PD2. The CNMX, DNMX and TNMX geometries have a cutting length of 3.4, 4.5 and 3mm respectively and all inserts have a 4.76mm thickness that promotes strength and rigidity. The three insert types are available with a corner radius of 0.4 or 0.8mm to prevent edge breakages and prolong tool life and consistency.
Both the positive and negative type single cutting edge inserts are available with a range of toolholder designations to suit all types of turning centre from the smaller sliding head centres through to heavy duty turning machines.
A variety of cutting tools exhibited included the new EXOPRO AERO end mill series for composites.
Ever dream of machining composites without delamination and tool life issues? Composites are constructed with layers of material that are prone to delamination. They are also known to be abrasive and could easily wear your tool down. If your tool loses its sharpness, the material gets pushed away instead of cut, producing uncut fibers. OSG’s EXOPRO® AERO-BNC routerovercomes these problems and even provides high feed roughing and a superior finish.
Longer Tool Life
The AERO-BNC also features OSG’s patented diamond coating which has a maximum diamond grain size diameter of 2μm. This ensures our coating is super smooth. Unlike our competition, we manufacture all diamond products in-house using our grinding technique on our special carbide substrate. This patented diamond coating coupled with the AERO-BNC router’s thick core diameter and multiple flutes extends tool life significantly. Improved part finish and sharper cutting edges are also the end results of the diamond coating.
The AERO-BNC is extremely versatile and can be applied in both thick and thin laminates. It is versatile enough to handle trimming, slotting and shoulder milling applications! It also can engage parts by plunging, ramping or helical entry and is available in various end cuts to enable you to find the right tool for your job.
More and more, we are asked this fairly simple question from shops who want to purchase BIG-PLUS® dual contact tooling from sources other than us. One would certainly think that this must be the situation, given that more than 100 of the world’s top selling machine tool builders have adopted the BIG-PLUS spindle system as their own standard. The truthful answer to anyone who asks is that this system has not been standardized by any governing body such as ISO, DIN, JIS, or ASME.
This comparison of licensed BIG-PLUS vs. unlicensed BIG-PLUS tooling shows how little or no taper contact in the unlicensed tool holder can allow “float” in the spindle taper with no positive radial location, causing large cutter runout and immediate fretting corrosion on that spindle face that can severely damage the spindle.
BIG Daishowa, the original developer of this system and a major reason that it has been so widely accepted throughout the world, still holds all of the proprietary information and, more importantly, the grand master gages that are used for reproducing spindles and tooling. Access to this information and gaging is well protected by BIG and is only provided to those companies who acquire a license agreement, mostly to protect the integrity of the system, which uses very close tolerances in order to function at its designed performance level.
The popularity of BIG-PLUS has surged over the past ten years as many shops have tried the system and have witnessed for themselves the huge benefits in higher performance and accuracy over standardized taper contact tooling systems, such as CAT or BT. Other dual contact systems, such as HSK, have also seen a rise in popularity for similar reasons, but perhaps not with all of the same benefits of BIG-PLUS. Unfortunately, all of this increased popularity and demand has been accompanied by a surge in unlicensed copies to the market that offer all kinds of promises and prices never seen before.
I cannot fault a shop for purchasing cheap dual contact tooling after being told by their supplier that it will work just as good as the originals for half the price. After all, human nature wants to find the best offer at the best price – that sort of deal is capitalism at its best. As consumers, we are all confronted with choices every day about buying similar products that do similar functions from a wide range of suppliers and costs. For me personally, I usually decide to buy cheap only when I know the product will be used one time and then thrown away. On all other purchases, I’m in it for the long haul and willing to pay higher prices. At the end of the day, I want to be confident I made the right choice for the long term, and I’m willing to pay more for my peace of mind.
Master gages for tooling are quite common. Generally all of them are traceable to a known master to compare the accuracy for rate of taper for production of tool holders, such as CAT or BT. ISO dual contact systems such as HSK rely on the use of a grand master gage that all other master gages are produced to, thereby guaranteeing that all HSK tool holders are the same everywhere in the world. Our company decided to find out how the world’s leading suppliers of HSK tool holders compared to the tolerances of the ISO standard. After acquiring more than 30 HSK-A63 taper tools from our competitors from all over the world and making a detailed quality inspection of the taper itself, we found that 50 percent of the samples were not in tolerance.
What are the consequences to a poorly researched choice in BIG-PLUS tooling? Unless all of the tools are marked “BIG-PLUS® Spindle System-License BIG DAISHOWA SEIKI,” the use of tooling not made by BIG Daishowa or its licensees may result in unsatisfactory performance and/or damage to very expensive spindles. Conditions producing such unsatisfactory performance include:

PMC-Colinet has a long history in the pipe and tube market, having started in 1912 and introduced the world’s first carbide-tooled pipe threading machine in 1958. Today, the company is established as a primary supplier of machines to the OCTG sector. Its customers include integrated steel mills that sell finished pipe and couplings to the oil and gas industries, specifically using the company’s machines for threading products for downhole drilling applications. PMC-Colinet also supplies cutting tools, consumable tooling, aftermarket parts and field service to the industry.
Recently, PMC-Colinet did an assessment on one very challenging job, namely, cutting keyways into large sections on a high-precision cutting tool head made of Nitralloy. For many years, the production had involved the use of a shaper to produce the keyway in the bore of the die head. Typically, the bore ranged from 6” to 13” in diameter and more than 12’ in length. These keyways have extremely tight tolerances, with location at +/- 0.0005”, width at +/- 0.001” and depth to +/- 0.0025”.
One style of cut is a 3-step keyway that does not run all the way through the bore, stopping at a window that is milled from the outside diameter. This situation prevented the PMC machining department from using a ram EDM to produce the keyway. The only options previously used were to rough the keyway on an old shaping machine, then send it out for ram EDM. This process required 50 hours on the shaper, plus approximately a week for the ram EDM. Another option was to do the job entirely on the shaping machine. Roughing the keyway had to be much more precise and usually required about 61 hours. Plus, an additional 145 hours were required to finish the part, normally. These times included 10-12 hours for set-up.
One competitor brought a standard 40 taper tool, while Heimatec presented a larger, heavier 50 taper unit.
A week later, Preben Hansen, Heimatec’s president, supplied a drawing for the proposed custom product. PMC engineering reviewed both the standard and custom designs and awarded the project to Heimatec.
The angle head supplied was designed to perform a wide variety of cutting tasks on the various end products produced by PMC. On the keyway in a bore 6” in diameter and 12” in length, using the Heimatec 90º head, PMC spent 6 hours in setup, 3 for roughing and 3 for finishing, plus 12 to 16 hours of actual cutting time. This represented a total savings of 184 hours on a single part. Though the head appeared too slender to remain rigid during the entire cutting cycle, according to PMC sources, the performance was deemed very successful.
Heimatec’s head design for this custom radial drilling and milling head features an adjustable tool stop, 3 support pins for stabilizing the tool, CAT 50 taper style, 360º indexable pivot on the angle head and inclined tooth gear design for maximum rigidity.
During the project, Preben Hansen from Heimatec supervised the installation. After the stop block attachment and grinding of the supports pins for the head were accomplished in just one day, the head was mounted and several experimental cuts were performed. Hansen spent time with Rick Kokish as well as CNC programmer Barry Spence at PMC, discussing various options for programming the head on the Monarch VMC. The very next morning, the setup was performed and an actual keyway was roughed.
Results ongoing have continued to satisfy all requirements, according to PMC sources.

There are a variety of Shrink Fit Toolholding Systems on the market, all of which use thermal contraction to grip cutting tools. However, while most Shrink Fit holders are one-piece type, OSG has improved upon this design with our “hybrid” Shrink Fit System. The word “hybrid” is defined as “something of mixed origin or composition” and this is what OSG has accomplished with our shrink fit system, as our holders have the accuracy and rigidity of Shrink Fit Holders, but the versatility of Collet Chucks.
HOW ACCURATE IS IT?
Since all surfaces are precision ground, OSG’s Shrink Fit System maintains a runout accuracy of 5 microns (0.0002”) or less. This accuracy is consistently repeatable, since our Shrink Fit Collets are made of a stainless steel alloy (rather than tool steel) and our hot air Shrink Fit unit keeps the heat to a manageable level. This high level of accuracy helps the customer to machine the part to a finished state without worry.
Using the OSG’s Shrink Fit Holders with standard cutting tools (rather than EDM or special extended-length cutting tools) save customers considerable money. OSG’s Shrink Fit Collets can also be modified to fit extremely tight spaces
In addition to accuracy and reach, OSG’s Shrink Fit System offers flexibility that others do not. One Base Holder can accommodate a variety of Shrink Fit Collets, allowing customers to keep initial investments low. Also, since Shrink Fit Collets can be used in any Base Holder, customers can use OSG’s Shrink Fit System in multiple machines simply by purchasing new Base Holders. This is particularly helpful since a shop can get greater versatility out of existing tooling when they purchase new machines.
MAXIMUM COST SAVINGS
OSG’s Shrink Fit System provides maximum accuracy, reach and flexibility, all of which contribute to increased productivity and cost savings. Your customers should consider our system not only for new tooling purchases, but also for improving productivity on existing jobs.
This article originally appeared in the May 2013 / Volume 65 / Issue 5 of Cutting Tool Engineering titled "Evolving toward digital" By Matt Tegelman, BIG Kaiser Precision Tooling Inc.
Boring tools with a digital readout aren’t the standard in U.S. shops, but their use is growing.Think about the number of digital equipment interfaces and interactions an operator has when machining.
Machine operators use keypads and computers to run tooling programs and measure parts with digital gages and coordinate measuring machines. By definition, CAD/CAM work is accomplished digitally. Machine tool controls have digital displays. On most tool presetters—even simple ones without a vision system—the readout is digital. Bore gages are digital, whether it’s an air gage or a three-point-contact gage. There are still a few old-timers who trot out ID micrometers once in awhile, but most measurement devices are digital for speed and accuracy.
Analog readout technology isn’t dead because it’s still highly effective for the majority of low- to medium-level tolerance operations. Few shops have yet to make the switch to digital boring across the board, and it will be a long time before more do so on a regular basis. Digital boring heads cost 60 to 80 percent more than their analog counterparts.
That said, as old boring heads need replacement and more operators become accustomed to the advantages of digital boring adjustments, there eventually will be a turning point in some operations where it makes sense to go all digital. This change won’t happen just because it’s the direction of the industry.
Don’t Sacrifice PerformanceIf a shop is considering moving from analog to digital boring tools, the best conversions are those that can be accomplished without having to replace any accessories—simple one-for-one boring head trade-offs. Still, ask questions to ensure this is the case with your shop. Users can defeat the purpose of digital ease of use if the head isn’t a 1:1 replacement and additional programming or tinkering is necessary when converting to digital.
For instance, Kaiser’s 112 EWD, 310 EWD and 318 EWD digital boring heads are otherwise identical to their analog predecessors. They have the same boring ranges, cutting parameters and through-coolant capabilities, so an operator can swap an analog for a digital model with little or no reprogramming. All three series use the same accessories, such as boring bars and insert holders, as their nondigital counterparts.
Despite the obvious advantages of digital, the technology isn’t yet for everyone. But as manufacturing and technology continue to become more and more entrenched in the digital realm, there will be a tipping point after which digital boring is the norm. Some shops will just be ahead of the curve. CTE

Digital boring heads from Big Kaiser were designed to be a simple 1:1 match to their analog predecessors - same boring ranges, cutting parameters, and through-tool coolant capabilities - so an operator can swap an analog for a digital model with little or no reprogramming. Just like your cell phone or computer, it won't be long until you wonder how you ever lived without a digital interface.
Make the leap to digital technology.
