You Have Options When Choosing a Saw Arbor

11/22/2022

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:

TI-LOC® Saw Arbors with integrated ER taper
Gold Star Precision Series Saw Arbors
General Purpose Series Saw Arbors
Custom Saw Arbors

Let's take a look at the differences below.

TI-LOC® Saw Arbors with integrated ER taper

Saw Arbor tiloc ER Clamping nut snapin assembly.

Twist and snap into any ER clamping nut. No special holding nuts required.

The 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 Saw Arbors

Gold Series reach saw arbors

Martindale Gaylee also offers a Gold Series reach arbor. These arbors are heat treated and ground to 0.0004” T.I.R. concentricity and squareness.

The Gold Series are engineered for use with carbide saws and where accuracy is a must. This VIBRA-CORE design, along with the deep low profile caps, gives extra support and less vibration.

General Purpose Series Saw Arbors

General purpose slitting slotting saw arbor

Martindale Gaylee's general purpose slitting/slotting saw arbors are all ardened all over (58/60 Rc) for added toughness on cutter locating surfaces and shanks.

The General Purpose Series Saw Arbors shanks ground to within 0.001" T.I.R. of cutter location diameter. They have an extra long, strong body with a protective black oxide finish. The super low profile on caps allows the cutter to reach areas inaccessible with conventional arbors.

Stout plug: extra support, less vibration sum up the benefits of this style. Oh, and Weldon style shanks are readily available.

Custom Saw Arbors

Custom made special saw arbors built to specification

An example of a Custom Saw Arbor

Can be made extra-long for reach beyond or inside part features

Accommodates multiple cutters for straddle or profile
Different outside diameter cutters on the arbor
ID grooving operations
Made with or without keyways

You can spec your own custom saw arbor

Metalcutting Circular Saw Cutting Recommendations, Tips, Tricks & Troublshooting

Martindale Gaylee Carbide HSS Saw Selection troubshooting tips tricks

As more and more of our customers are using Martindale Gaylee Circular saws we put together this guide to the commonly asked questions such as "Is there a rule-of-thumb for the number of teeth?" or "How much side clearance should I have?" Here we cover a lot of the fundamentals of selecting the right circular saw blade configuration, some tips, tricks, and troubleshooting for when things go wrong.

Circular Saw Feed Rates

These are general cutting speed recommendations for circular saws used in metalcutting from Martindale/Gaylee. The may vary from application to application but are basically some general suggestions starting parameters when using high speed or carbide saws.

HSS Saws: .002”-.006” (IPT-inch. per tooth / CLPT-chip load per tooth)
Carbide Saws: .0002”-.0015” (IPT -inch. per tooth / CLPT - chip load per tooth)

This is a conservative recommendation as a starting point for feed rates, and may vary depending on material being cut and cutting speed (SFPM).

Selecting the Proper Number of Teeth in Your Metalcutting Saw

Generally speaking, deep cuts and soft material require fewer teeth for chip clearance and stronger teeth (landed) Thin material requires more teeth, but keep-in-mind that at least 2 teeth on the blade need to be engaged in cut.

Hard materials and narrow slots (under .025”) likewise require more teeth.

Hard Materials require more teeth, and give a smoother cut, but at a much lower production rate.

Alternately beveled teeth keep chips from sticking in the cut and in the tooth gullets.

And Remember that there should be at least 2 teeth engaged in the cut at all times.

Increase Number of Teeth For:

Thin material
Thin cuts under .025”
Slow spindle speeds
Hard material
Sand castings
Thin castings
Work hardened materials
Known inclusions or Hard spots

Decrease Number of Teeth For:

Free cutting material
Soft Gummy long chipping materials.
Deep cuts (over 1/4”)
High speeds Machining Applications
Chip clearance and tooth strength (Consider Metal Slitting or Copper Slitting style saws.)

Rake Angles and Side Clearance Angles

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.

RAKE ANGLES
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.

Why do Circular Saw Blades Break?

It's commonly known that when saw thickness is less than 0.125″, keyways can cause stress risers and cracks. That is why washers are often used. However, Breakage, Wobble and Rubbing problems are often caused by how the washers are mounted on either side of saw.

Remember, washers drive the saw in the absence of a drive key. They must always be clean, flat and bur-free. A speck of dirt will let saws wobble and cut oversize.

If a saw breaks, it may score the washers. Always check for scoring marks around saw hole for dirt, chips or grit. Shiny spots, as small as a pinpoint, indicate that chips where imbedded under washers.

Circular skid marks indicate the nut was not tight.

Generally speaking:

Thin saws should especially be supported by washers as large as possible.
Washers must be of equal diameter or they will flex out saw dish and cause one side of saw to rub.
The nut must be wrench-tight.

Saw Blade Teeth most often break as a result of:

Too high a feed rate.
Spindle bearings are worn.
Drive belts are loose or sheaves worn.
Improper tightening: If saw blade pauses momentarily in its rotation while feed advances, it WILL break.
Workpiece indexed before the saw has cleared the slot.
Improper workholding - The workpiece not tight or not well supported.
Saw is dull, even the best tools do eventually wear out.

NOTE: HSS saws will turn colors as they heat during cutting. A straw color is the limit. The saw will lose its temper when it starts turning blue.
