In the below video Matt Saccomanno the founder of Masa Tool describes how the Microconic workholding system functions without the need for an extended nose collet: The Microconic cartridge replaces the extended nose collets and provides not only better clearance but more rigidity and accuracy in the sub spindle of a CNC Swiss Style lathe. According to Saccomanno, "The accuracy and rigidity greatly improve with the diameter clearance already built into the system."

Edited by Bernard Martin Often times in a shop, a saw arbor is a saw arbor is a saw arbor. That's just not the case and Martindale Gaylee offers several solutions. They have variants to saw arbors to meet your specific needs whether it be in a CNC milling machine, a CNC Lathe, a manual mill or even a Swiss Style CNC machine. This includes:
Let's take a look at the differences below. TI-LOC® Saw Arbors with integrated ER taperThe Ti-Loc® SwissClamp System is a taper-integrated small tooling system is designed to work with virtually any collet or tool holder that employs the ER collet system (DIN6499). The Ti-Loc directly mounts into ANY ER Taper Live or Static Tool Position. The Ti-Loc® System works with any existing tool holder and most all ER collet clamping nuts. Simply insert the Ti-Loc holder into any ER nut and twist to align the locking cam profile jus was you would for any ER collet. The Ti-Loc® SwissClamp System can be used in any machine that has ER collet live tooling. It comes standard with ER 11, ER16 and ER20 taper arbors that serve as their own collet, eliminating need for two-piece arbor system. This single piece design adds rigidity of set-up and improves total indicated runout (TIR). In fact, it reduces tolerance “stacking” to an incredibly low TIR of less than 0.0002". To top it off, it's less expensive & more cost effective than most comparable two-piece arbor systems. A recommended maximum saw thickness is approximately 0.080” Gold Star Precision Series |

Rake Angles and
Side Clearance Angles
Just as in an end mill or a band saw blade, a rake angle is the term used to describe the direction of the blade’s teeth, as referenced from the rotation and central axis of a saw blade. If you imagine a line going from the exact center of the blade to each tooth, having the front of the tooth directly on that line would be a zero degree rake angle. The rake angle of the blade is described in comparison to that imaginary line.
A positive rake angle meana that the teeth are angled more towards the angle of rotation, while a negative rake angle would mean that they are angled backwards, away from the direction of rotation. Generally speaking, the preferred rake angle is:
- 5° to 10° positive for other soft materials.
- 5° negative for yellow brass
- On center for steel.
SIDE CLEARANCE (Tangential Clearance Angle)
This is also known as dish or hollow grind. You measure down the side of the tip and the difference it is the difference between front and back. As you cut, material it gets compressed and springs back after the cutting edge passes.
A steep side clearance angle gives plenty of room for the material to expand and prevents thermal expansion of the base material. Keep in mint that a very flat side clearance angle can provide a smoother cut in some materials. For stainless steel and tenacious metals such as copper, zinc, tin or lead an increase in the side clearance is desirable as these materials tend to "spring back" (thermal expansion) on the blade.

The plugs are designed to prevent chips and coolant from accumulating inside receiver bushings that are not in use during certain operations. This saves time by eliminating the need to clean out the bushings between setups. The receiver plugs are made of blue anodized aluminum, providing durability for better resistance to hot chips when compared to plastic plugs.
The flush mount design means the plugs do not protrude above the subplate surface, making it easier to clean and avoiding interference during machining. These plugs are available in standard sizes to accommodate different hole openings and come with an O ring and tapped hole for easy installation.

The primary components for the company’s photoactivated adhesive system are a UV light source with a light guide, BlueGrip adhesive and UV light-transmitting grippers that serve as lenses through which the UV light passes to cure the adhesive and bond a part to a fixturing element.

To do this, the top of each gripper and the areas of the part to be gripped are cleaned with isopropyl alcohol. Adhesive is deposited on the top of each gripper so that the entire gripper face is covered and the gap between the face and underside of the part is filled. The gaps (thus, the thickness of the adhesive) can range from 0.020 to 0.120 inch, depending on part flatness. The part rests on hard stops installed in the fixture plate that are slightly taller than the gripper tops to achieve the proper gap.

Once machining is completed, a wrench is used to back off each threaded gripper, shearing the adhesive bond with the part. The residual adhesive can then be peeled off the part and grippers after applying steam, or a hot water soak or spray.
The number of required grippers is based on the size of the part and its geometry, the company says. Axial holding force depends on gripper size and can range from 250 to 800 pounds. Grippers are made from hardened, corrosion-resistant stainless steel and have a black oxide finish. The adhesive is compatible with most water- and oil-based coolants and cutting fluids. It is said to be able to hold a variety of ferrous and nonferrous metals as well as plastics, ceramics and composite materials.
