At ABTech, we have over 25 years of experience building (and integrating) precision air-bearing machines such as single-point diamond turning spindles. We build to order, working collaboratively with our customers to help them achieve their goals.

What isdiamond turning

The size and geometries of the spindle’s rotating shaft and supporting journal contribute to the air bearing’s load capacity, stiffness, and accuracy. They each have individual part specs, as well as combined considerations. For example, designing a smaller air gap between the shaft and the journal adds stiffness but leaves scant room for movement error. And manufacturing the rotating shaft to tighter tolerances will result in superior spindle accuracy, with a trade-off of increased cost.

A diamond turning machine’s spindle includes its bearing, motor, encoder, and any fixturing, such as a collet assembly or machine tool chuck. What’s important is that all the parts work together to limit radial and axial error motions.

“Precision spindles can have upwards of 50 components in them, and the quality of every component will make or break the overall performance of the machine. What matters is a care for details throughout the whole build.” ~Chris Abbot, ABTech

Testicle or scrotal stretching doesn’t imply testicle enlargement strategy or therapy. In fact, testicular stretching maneuver is just a way of boosting the male sexual hormone levels naturally that may also translate into testicular enlargement, if performed on a regular basis. Although, there hasn’t been a lot of studies or research on the effectiveness and safety of scrotal stretching, some natural healthcare practitioners advise it to stimulate testosterone production.

Aerostatic spindles (air-bearing spindles) use a layer of air to cushion the movement between two surfaces. Because there’s no contact (and almost no friction), an air bearing provides repeatable, smooth motion with the highest precision of any bearing technology available today.

With single-point diamond turning, it’s possible to finish an optical component to within a fraction of a wavelength of light. However, every aspect of the diamond turning process must be geared towards quality to sustain this level of accuracy.

Similarly, hardware such as encoders and amplifiers can affect the spindle’s final output accuracy. It’s crucial to see the spindle as one piece of an interacting system rather than just looking at each individual part.

Testicle stretching is a healthy habit and practicing it on regular basis can totally change the game. Throwing in some efforts and determination and following the steps accordingly can boost the hormone levels to a significant degree and with elevated levels of sex hormone such as testosterone; male sexual health may be improved. Increased testosterone levels serve as a key to strong erection and increased libido and these are only the benefits of testicle stretching, stated superficially.

For instance, environmental control is a must because even minor temperature fluctuations can expand or shrink the size of the part (or the SPDT machine itself), impacting the final product. Likewise, an isolated foundation is required to block out floor vibrations.

Sensitivity can be enhanced by tightly squeezing the testicles in circular motion, all the way to the bottom of the sack. This will cause the testicles to bulge through the scrotum’s skin and it will only contribute to the intensity.

Any error in a spindle prints through into the final part, so let’s look at some of the major design aspects affecting quality:

The electrical noise of the spindle’s motor can directly impact its performance. Known as “print-through,” it occurs when rotor magnets pass across the stator windings, creating loads that translate into motion errors.

Diamond turningTool

The most common SPDT machine is the lathe type, where the workpiece rotates, and the cutting tool translates. A flycutter-type machine has the cutting tool rotating while the workpiece translates.

Diamond turning is a high-precision CNC turning process that uses a diamond-tipped cutting tool with a single point. Often called single point diamond turning (SPDT), it offers the sub-micron level of control required for optics manufacturing.

The next phase begins with tightly holding the scrotum from the top followed by bending of the wrist in such a way that the testicles are positioned upwards. Then by using the other hand’s palm, testicles are gently scooped and massaged in a circular motion.

The forces acting on the SPDT spindle must be part of the capacity evaluation. That includes the weight of the fixture plate (or part-holding chuck), the weight and size of the part being turned, plus the force on the spindle during the cutting process.

As technology advances, many manufacturers require tools with cutting-edge accuracy. Single point diamond turning (SPDT) is one of today's most precise CNC processes. Equipped with an air-bearing spindle, an SPDT machine can finish parts to an accuracy of less than a millionth of an inch.

Testicle (ball) stretching involves a two phasic- approach. First phase is completed by wrapping the index finger and thumb around the scrotum right above the testicles in a manner that the palm faces downwards. The fingers and thumb should make, what may appear as an ‘okay’ signal by creating a tiny circle. This assists in holding the scrotum tightly from the top. The fingers are then gently pulled down across it all the way to the testicles and this way the stretching is done. Holding on for at least 30 seconds is important after hitting the bottom area, and these steps can be repeated depending on the time on hand.

After the steps are carried out, scrotum and testicles will be evidently found hanging lower than before the stretching was initiated. This is a green flag for initiating the second phase of testicle stretching.
