Are you installing your Collets correctly?

7/12/2017

Techniks Collet CHuck Assembly
Installing ER (DR, RD, ESX) , style collets is very common in every machine shop and tool & die shop, but is everyone doing it CORRECTLY?

Did you know that there is a torque specification on your collets?

Many people use a cheater bar to tighten down collets believing that the "tighter is better" but that's not always the case.  Like all toolholding collets, ER style collets are spring collets with a 30 degree front taper and a 16 degree back taper (a "free releasing 'locking-taper" just like your steep taper toolholder) 


​When the 16 degree taper "locks" and you continue to over-torque the collet nut, the collet can twist and, under the normal load of cutting conditions, the cutting tool will run-out.  

We also recommend using a tightening fixture and torque wrench to make sure cutting tools and retention knobs are properly tightened.

Over-tightening can distort or even crack collets, causing runout problems and premature failure of the collet, nut, tool holder and cutting tool.
​
Under-tightening can also cause poor cutting performance, or allow cutting tools to fly out of the spindle – a very serious safety hazard.

Everything you wanted to know about the Microconic #Workholding System

5/17/2017

0 Comments

 
Matt Saccomanno, the inventor of the Microconic Workholding system discussed how it works 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 system consists of two major components: The Microconic™ cartridge, which fits into your CNC machine spindle replacing the standard 5C, TF20 or TF25 collets, and the Microconic™ collet, which fits in the Microconic™ cartridge. 
​
The Microconic™ system has unsurpassed concentricity: Our manufacturing tolerance is 3µm (.0001") and we guarantee our cartridges to be within 5µm (0.0002") in production use in your machine.

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.

Ultimate Guide to 3D Printing Thermosets

4/21/2017

This article examines the difference between traditional SLA, DLP and 3SP for additive manufacturing in a large build envelope when high accuracy, repeatability, reliability and throughput are required.
​

After more than three decades of research and development, 3D printing is ready for prime time in manufacturing — production of high-value parts and mass customized products, in addition to prototypes, injection molding tooling, end-of-arm tooling and assembly jigs and fixtures.

In fact, a variety of manufacturers have been using 3D printing, also known as additive manufacturing, this way for years now, with more adopting the technology every day. In addition to manufacturers of all sizes, the range of production users also includes laboratories, hospitals and Hollywood studios.
​
Did you know, for example, that the global hearing aid industry has been mass producing custom hearing aids with 3D printers for more than a decade1? In recent years, dental laboratories have also been mass producing dental and orthodontic models, which require high XY accuracy and a smooth surface finish. This has eased the way for the mass production of clear thermoformed aligners for teeth straightening, in addition to other dental products. And in 2016, General Electric began mass production of metal fuel nozzle injectors for its LEAP jet engine using 28 additive manufacturing machines — validating the idea that 3D printing
isn’t just for prototypes anymore.

The University of Michigan-Dearborn chose EnvisionTEC’s large frame 3SP technology to 3D print large parts for its Formula SAE Electric race car project. Watch the video at EnvisionTEC.com/automotive
Vat photopolymerization, in which a light source is used to selectively cure or harden photopolymer resins inside a vat or tray, has become a popular method of 3D printing among manufacturers for a variety of reasons.

For example, the photopolymer resins used during this process are also known as thermosetting plastics or thermosets, which strengthen during post-curing and hold their shape, even after reheating. This is in contrast to thermoplastics, which can be re-melted after being formed into a part. A wide range of thermoset materials are also available today with a variety of desirable properties, such as epoxies, which offer elasticity and exceptional chemical resistance, as well as biocompatible materials.
​

The vat photopolymerization category includes stereolithography (SLA), digital light processing (DLP) and a new method launched in 2013 called 3SP for scan, spin and selectively photocure. 3SP specializes in affordably building accurate parts with a smooth surface finish across a relatively large build envelope, where traditional SLA and DLP have challenges scaling up in size affordably. This allows for 3D printing of a single large part or a tray of smaller parts.
To understand why 3SP is so unique in its benefits, it’s critical to understand the limits of SLA and DLP. 


Understanding SLA vs. DLP

One of the earliest forms of 3D printing, SLA was patented in 1986 and commercialized by 3D Systems.
In SLA systems, a UV laser beam literally draws — lithography means “to write” — out a part into a vat of resin. Wherever the light hits resin, curing or hardening occurs. The laser beam can be positioned either above or directly below the vat, and each approach has its own pros and cons.

However, for most large manufacturing systems, the laser is typically positioned above the vat and curing takes place on the upper layer of resin in the vat or tray. This approach allows for the largest build envelopes and lower gravitational forces on the part being built. After each layer is built onto a build platform inside the vat, the platform is lowered in the Z axis so the next layer can be cured onto the part.

How to Prepare for the Widening Skills Gap

3/1/2017

This article original appeared on Ganesh Machinery's Blog.
Picture
DID YOU KNOW that over the next decade more than 3.5 million jobs will need to be filled? And according to The Manufacturing Institute, we will only be able to fill roughly 1.5 million of those jobs. With all of those jobs left unfilled, you can only imagine how many companies will get left behind because they lost the ability to produce. Take a look at the harsh reality we’re facing:

Every year we see more reports and forecasts urging manufacturers to do something about the skills shortage. It’s time for us to do our part and we want to empower you to keep manufacturing alive and well in America. It starts with the youth.
​

“Manufacturers are the key to solving this (skills gap) problem. By aligning together and clearly defining their needs—and speaking with one voice, they can work with secondary and post-secondary schools and government to create a system that attracts, develops, and retains skilled manufacturing talent.”
-Dr. Charles (Chip) Blankenship, President and Chief Executive Officer, GE Appliances & Lighting

We stopped engaging with younger generations and we stopped sharing our technological advances in the machine tool world. As a result, most millennials think manufacturing is a dying industry. They have no idea how many amazing opportunities are available for them to become engineers, programmers, product managers, marketers, and the list goes on.

​In order to transform our industry’s reputation, we need to work with schools to show students what modern manufacturing really is.
Picture
In December, we did just that. We donated our robust GT-1640 lathe to Simi Valley School and Institute to support their machinist training program. “The GT-1640 is ideal for this type of work because it is a powerful and precise lathe. It is also the type of machine students can expect to see when they enter the workforce,” said Simi Valley Lead Instructor Oygar Lindskog. >>Read the full story here.
​

While it may seem like giving away a machine is a big chunk of change, we know it will pay off in the long run. It’s our contribution to educating and invigorating people so that manufacturing continues to grow and thrive in America for generations to come.

Want to help bridge the skills gap? Here are some things you can do to grow the pool of manufacturing talent:
  • Donate equipment to local schools
  • Offer apprenticeship programs
  • Invest in training your current staff to get them up-to-speed
  • Work with staffing agencies
  • Sponsor certification programs
  • Work with local trade schools, high schools, colleges to:
    • Create internship programs
    • Plan field trips to your facility to show them cutting-edge technology
    • Produce job fairs
    • Speak at events about opportunities in the industry

As passionate manufacturers, we want to see our industry grow and help incoming generations succeed. Let’s work together to make that happen.

Prolonging Tool Life of Deep Hole Drills by Using the Appropriate Pilot/Starter Drill

12/14/2016

9 Comments

 
Guest Blog by Cory Cetkovic, Product Manager, Sphinx, Big Kaiser
Selecting the appropriate pilot drill is critical to maximize performance and tool life of a succeeding deep hole or micro drill. The purpose of a pilot drill is to create a clean, consistent working surface for the succeeding drill to enter the workpiece.

Important aspects such as diameter tolerance and point angle (Figure 1) are often overlooked leading to inconsistent, unacceptable results.

A pilot drill diameter should be slightly larger than nominal diameter, whereas the succeeding drill diameter should be smaller. This is often accomplished using positive and negative tolerances respectively (Figure 2). Selecting the incorrect pilot drill diameter can lead to premature failure of the succeeding drill as it will enter the pilot hole using its margins rather than its center-cutting point.
​
It is also important for a pilot drill’s point angle to be equal to or larger than that of a succeeding drill. The purpose of a larger point angle is to guide the succeeding drill to centerline while preventing its corners from colliding with the point angle left by the pilot drill. Using a pilot drill with a smaller point angle usually results in chipped corners on the more expensive deep hole drill after drilling 10-20% of the expected tool life.

Figure 2. Demonstrates one method of achieving the appropriate pilot hole diameter. The pilot drill and succeeding drill have equivalent nominal diameters, but tolerances prevent the pilot hole from being smaller than the deep hole drill diameter.

OEMETA’S HYCUT OFFERS GOOD ECOBALANCE

11/28/2016

0 Comments

 
Oemeta presents a study on the environmental impact of cooling lubricants in metalworking 
Using Oemeta’s mineral oil-free, multifunctional HYCUT oil for metalworking significantly reduces the environmental impact when compared to an equivalent mineral oil-based cooling lubricant system. This was indicated in a study on environmental impact, conducted in collaboration with the Technical University of Braunschweig, in accordance with the standard life cycle assessment (LCA) method. In crankshaft production, one original equipment manufacturer (OEM) managed to save the equivalent of 470 tonnes of CO2 in one year.

“We expected a good ecobalance, but both we and our customer were pleasantly surprised by just how positive the results were”, says Stefan Joksch, Technical Director at Oemeta. According to a study titled “Life Cycle Assessment of Metal Removal Fluid systems in metalworking applications – Evaluation of environmental impacts using the example of crankshaft manufacturing”, Oemeta’s HYCUT system can improve environmental values by up to 60%.

The study was initiated by Oemeta, in collaboration with a German manufacturer of premium automobiles, and conducted by the Institute of Machine Tools and Production Technology at the Technical University of Braunschweig. It uses LCA to analyse the potential environmental impacts of mineral oil-free, multifunctional HYCUT oil, and compares these impacts to those of a conventional mineral oil-based lubricant system.

In order to comprehensively evaluate a product’s environmental impacts, the product’s entire life cycle – from raw material extraction through to manufacture, use, and disposal – is taken into account. The assessment measures both the consumed resources, and the emissions produced along the life cycle of the product.

​This occurs across all of the examined processes, such as production and disposal processes, energy generation, transportation etc., and converts these values into environmental impacts. The results are related to an indicator substance. For example, global warming potential (GWP) is related to the indicator substance CO2 and given in kg CO2 equivalents. 

Carryover of metalworking fluids is not a problem
The investigation was carried out as part of a case study on the process chain in crankshaft production, which looked at a diverse range of machining methods, such as milling, turning, deep drilling and grinding. As the process chain frequently alternates between steps involving water-miscible and non-water-miscible cooling lubricants, washing processes are integrated between the steps.
​
Using ester-based, multifunctional HYCUT oil ensures that water-miscible and non-water-miscible components are compatible. This means that the introduction of metalworking fluids by means of adherence on components is no longer a concern.

On the contrary: Oil that has been carried over is used as a lubrication performance in the emulsion during subsequent processing. Compared to mineral oil-based benchmark products, this results in a much more efficient use of cooling lubricants throughout the entire manufacturing line. Intermediate steps can be eliminated and metalworking fluid waste is practically non-existent.

​Reusing the washing agent, employed to clean the components, as a cooling lubricant during the manufacturing process also has a positive effect on the ecobalance. In summary, the use of the HYCUT system significantly reduced the environmental impacts (40-60%) in all of the categories examined throughout the entire life cycle.

However, when machines are used incorrectly or without caution, damage to the wheel can occur.
Be sure to follow the instructions below to ensure safe operation.
​
Picture

NORITAKE GRINDING WHEEL OPERATIONS AND HANDLING INSTRUCTIONS:
  1. The three main rules of handle Noritake grinding wheels are “do not roll ”, “do not drop” and “do not bump.”
  2. Grinding wheels should be stored in dry locations and on shelves.
  3. Before attaching on a machine you should perform a visual inspection and ring test. This will ensure that there are no cracks, splitting or chipped areas.
  4. Make sure that the maximum speed and size indication on the wheel correspond to the machine.
  5. Place Flange with the outer diameter and contact width are equal on both sides. Check to make sure you have the correct flange size before installing.
  6. Use the blotters that come with the grinding wheel to insure proper installation. Make sure the flange diameters are larger than the blotters.
  7. After installing flange balance the wheel with the proper weight distribution.
  8. Ensure a gap of 3 mm or less between the wheel and work rest piece. Make sure to leave a gap of 3 to 10 mm between the wheel and the adjustable torque.
  9. The wheel mounting point should be used with a wheel axle lengths of 13 mm.
  10. A proper wheel shield should cover at least half of the grinding wheel diameter.
  11. After installation of a grinding wheels a pre-operation run should occur for at least one minute before grinding starts, and at least three minutes after replacing a grinding wheel. Portable grinders should be test-operated in a safe location.
  12. Safety equipment including PPE and dust-proof masks should be worn during grinding operation at all times.
  13. To prevent imbalance of the grinding wheel shut down coolant flow before stopping the wheel. Allow the grinding wheel to continue rotating in order to dry.
  14. Friction sparks should be contain by a screen or operation guard.
  15. Proper ventilation is highly recommended to prevent respiratory illnesses.
