NEW Vario Visio DIGITAL adjustable aggregate head

Smart Line Vario
We've offered CNC Aggregate heads with adjustable angles for some time. Our Vario can operate at any angle within it's range to perform “impossible” cuts, …right on your CNC router. The Function Line Vario aggregate operates at any angle from 0˚ to 100˚. We've also had the The Ultra Line Vario aggregate that operates at any angle from -100˚ to 100˚ Each of these uses a Vernier scale on the side of the unit to adjust it.

The vernier scale is great but we thought that it was time to go Digital! Our new Vario Viso has a easy to adjust head and a DIGITAL Display which really makes it easy for Boring, Routing, and Sawing.

Here's some of the Tech Specs:
  • Speed max.                 15,000 R.P.M. (drive)

Can the sPINer help your company Deburr? It's not for everyone...

Process Benefits
Eliminate expensive and time-consuming manual methods!
Many manufacturers of small parts are required to deburr parts by hand due to several factors (critical tolerances, burrs in the ID, external threads, light/thin areas prone to damage, etc.). The sPINner uses a very small stainless pin media available in sizes under 0.008” diameter. This allows the sPINner to deburr areas without damage to critical tolerances and can deburr even very thin work-pieces without deforming the parts.

Deburr ID areas and small holes!
The small size of the media driven by a magnetic field allows the sPINner to deburr ID areas and cross-holes not possible with other technologies. The small size if the media (to under 0.008” diameter) can help deburr holes from 0.010” and up.

Deburr parts with external threads!
External threads pose a problem for traditional deburring technologies since the threads would be damaged from grinding of the media. The sPINner media is not destructive to threads. In fact, due to the small size of the media it can help remove galling or chattering lines at the base of the thread and help gently smooth threads without damage.

Eliminate media jamming!
The deburring media used in the sPINner does not have the same breakdown characteristics of ceramic media used in other technologies. Traditional ceramic media is designed to breakdown during processing. This results in the media changing size and dimensions over time that can begin to jam in the parts. The stainless steel media used in the sPINner does not suffer from this limitation and will not dimensionally change. The sPINner media last about 2-3 years in most applications. This means a media size can be used without the fear of jamming!

Eliminate parts washing after deburring!
Parts typically need washed after processing in other technologies due to the fact these processes leave a residue of ceramic or porcelain sludge or dust on the parts. The stainless media used in the sPINner does not create this sludge. The result is that parts come out of the sPINner clean. This can eliminate the need for a separate washing after deburring saving both time and money!

Eliminate sludge in the wastewater!
As mentioned above, other technologies use a media (ceramic or porcelain) that breaks-down during processing parts. This leaves sludge in the wastewater that needs removed before the water can be either drained or recycled. The sPINner uses a stainless media that does not breakdown during processing like ceramic media. The result is the wastewater is free of sludge. This can help eliminate the separate processing of the wastewater to remove the sludge saving money.

Reduce cycle times!
Cycle times in the sPINner vary according to the specific application. However, generally the cycle times in the sPINner are a fraction of the time required in traditional vibratory or tumbling technologies. The table below gives some guidelines on cycle times.

Material Est. Cycle Times
  • Aluminum  5-15 minutes
  • Brass 5-20 minutes
  • Copper 5-20 minutes
  • Stainless Steel 10-20 minutes
  • Titanium 10-30 minutes
  • Steel 10-30 minutes

Again, the individual application will determine the actual cycle time required.

Fits Any Size Operation!
The sPINner is available in four sizes ranging from desktop units with 6” diameter containers to floor standing models with 21” diameter containers. There is a sPINner to fit both centralized deburring and cell manufacturing!

What kind of burr can the sPINner magnetic deburring remove?

What kind of burr can the sPINner remove?
We are often asked, “What kind of burr will the sPINner remove?” The standard answer is “a light burr”. This answer leaves a lot of room for interpretation. What is a light burr to some will be a heavy burr to others.
 The rule of “Thumb”:
In order to form an initial evaluation if the sPINner will work on a particular part try the rule of “thumb”. As a general rule, if you can take a fingernail and remove the burr, the part has a good chance of testing well in the sPINner. Burrs heavier than this may tend to roll and flatten, but not be removed during the process. 
A quick lesson on burrs:

To the left is a drawing of a cross-section of a burr on a part. From the drawing you can see some main areas we will be concerned with; the part itself (parent metal), the burr thickness at root, burr thickness, and burr height. 

Light Burrs
A lighter burr can be loosely defined as a burr with a thin thickness at root (B1). As the amount of material holding the burr to the parent metal increases, a more aggressive deburring action is required to remove the burr. Using this definition it is possible to have burrs that are tall, yet are “lighter” by our definition because the thickness at the root is small. Burrs of this type are good candidates for the sPINner. 

Short Heavy Burrs
An example of short, yet heavy burrs are the ridges created from drilling. When a drill breaks through a part a ridge is pushed up around the hole on the side where the drill breaks through. While this ridge can be short in burr height (H0), the thickness at burr root is wide. Often this material is more a part of the parent metal than the burr. These burrs will not be good candidates for the sPINner as a very aggressive and abrasive action that has a high stock removal rate is required to remove these burrs.

Brittle Materials
Another factor to weigh in this process is the material itself. More brittle materials will tend to have the burr break away from the part (parent metal) making the sPINner a good option.

Softer Materials
Softer or more malleable material will tend to have the burr roll and flatten. Softer materials need to have a thinner thickness at root to be good candidates for the sPINner.

Little Pins Pack A Powerful Punch for Medical Devices

The famous actress Judy Garland is said to have adlibbed about fellow child-star Micky Rooney: "It's the little things that matter". For central Indiana based Greenwood Machine, little burrs in a 1mm slot, mattered a lot.
Even the smallest burrs were not acceptable for this critical tolerance (0.0001” air motor. The company had an opportunity to diversify into the medical industry, manufacturing an air motor for a biopsy device that takes breast tissue samples for diagnostic analysis. Metal burrs left over from the manufacturing process were a part quality problem that had to be solved before they could move ahead with the project. These burrs could not be removed with conventional tumbling equipment, and that limited Greenwood Machine's ability to provide the quality and quantity of parts the customer needed.

While looking for alternative deburring technologies, they discovered the sPINner small parts deburring machine. They found that it's unique stainless steel pin media was able to quickly deburr the small slots.

With 25 years in the business, Greenwood Machine's owner Fred McWilliams has loads of experience producing small, complex parts. His business began machining small, precision parts (primarily RF connectors) for the electronics industry, and has grown to include a variety of quick-setup, short run jobs, and also some high-end bicycle components.

When the opportunity to manufacturer the air pump came up, Fred decided to move quickly and increase capacity by purchasing a bar-fed, Citizen/Cincom M32 CNC swiss-type turning machine to expedite production of the air pump.

This configuration allowed them to perform 3 operations at once, giving them a big advantage in cycle time. Their customer asked that they produce prototypes within 3 weeks of the CNC machine hitting their floor.

During the few weeks they had to set-up the machine and begin running prototypes, the deburring problem was discovered by Manufacturing Engineering Manager Joe Bowman. Joe's background includes experience with ISO 9001 certification and 8 years in CNC machining. He manages all the manufacturing processes even down to the CNC programs and setups. "This part is a cylindrical rotor that has 6, 1mm slots, each cross-drilled twice. The burrs in the 1mm slots could not be reached with our conventional tumbling deburring equipment, and our only other options were deburring by hand or sending the parts out for electrolytic deburring". said Joe. Both options were unacceptable due to the additional cost and time they added to the production cycle.

Joe had heard about the sPINner from Earth-Chain, and sent some sample parts to Mike Andrews for testing. A few days later the parts were returned, completely deburred, with a report documenting the media used and the run time (20 minutes).

Pleased with the results, Fred and Joe went ahead and purchased the sPINner and have been very satisfied with it. “This machine paid for itself in about a year. It reduced our cycle time, and gave us the ability to control quality in house.” said Joe.

The sPINner saved Greenwood Machine 17% on the cost to deburr each part compared to hand or electrolytic deburring, and even though they expect to nearly double production this year, they know deburring will not be a bottleneck.

According to Bowman “The sPINner is unlike other deburring technologies because the media is stainless steel pins, hardened to HRC 30 for long life. These special pins are why the sPINner can deburr small, complex parts so well.”

The parts and pins are placed in a deburring container and media solution is added. Next, the container is put into the machine and the cycle time and rotation speed is set. While it runs the pins are activated by a rotating magnetic plate underneath the deburring container. This causes the pins to rapidly reverse polarity, and jump up and down from 1 to 3 inches while rotating in the deburring container along with the parts. The parts and pins "spin" together to perform the deburring. The sPINner can even deburr internal cavities like slots and cross-drilled holes other media cannot reach.

Michael Harris, Vice President at Precision Finishing said: “The sPINner works best on small, precision parts made from non-ferrous metals including aluminum, brass, copper, stainless steel, and even titanium.” The aggressiveness of the deburring is controlled by programming the speed of the magnetic plate and selecting from a variety of media sizes. The machine is easily programmed and can run unattended.
