Products, Capabilities and Examples of what we do

There are several different methods to knurl a part, each with varying results and quality. We have invested in the method which provides the highest quality possible, cut type knurling.

Cut type knurling gives the best possible and most reliable outcome, very important when a part needs to be functional and aesthetically pleasing.

ANSI B92 is the most common standard when it comes to splines, B92.1 being imperial and B92.2 being metric.

There are three types of fit;

Fillet Root Side Fit

Flat Root Side Fit

Flat Root Major Fit

Each and every fit will work with each other, the fit is more of a strength and manufacturing detail. The most common is the Flat Root Side fit as this allows a tool radius and gives good strength, a fillet in the corner prevents fatigue cracking. Fillet Root Side Fit gives the largest fillet but can potentially cause weaker splines. Flat root major fit leaves little room for a fillet, potentially stronger splines at the high risk of fatigue cracking. 

Generally the strongest combination with lowest risk of fatigue cracking would be both internal and external Flat Root Side Fit.

The picture shows 6 of the same size splines with all the fit types for both internal and external. The thing to note is that for the internal fit the minor diameter stays the same, the major is what gets smaller from Fillet Side to Flat Major. 

A spline will be defined as 30-12/24-20 Flat Root Side Fit.

30 is the pressure angle, almost always 30 degrees.

12/24 is the spline pitch, 12 diametric pitch, 24 stub pitch

20 is the number of teeth.

This spline may also be defined as 1-3/4-20T 

I use an online B92 spline generator to get all of my dimensions and generate the spline to the middle tolerances, it is up to the customer to confirm if these are ok or send their own tolerances.

As in the picture I used the wire EDM to cut a bunch of common spline types, mostly as a template for in person customers. I can also cut custom splines to any pattern the customer wishes.

Here is an average cost for a one-off part for every inch of thickness. Multiple pieces will be given a discount.

30-16/32-9  or 5/8-9T will cost $54 per inch

30-16/32-13 or 7/8-13T will cost $70 per inch

30-16/32-15 or 1-15T will cost $80 per inch

30-16/32-21 or 1-3/8-21T will cost $105 per inch

30-12/24-14 or 1-1/4-14T will cost $95 per inch

30-12/24-20 or 1-3/4-20T will cost $130 per inch

This is a 2 inch long shaft coupler with an 8mm bore and 3mm keyway. This part does not exist on the shelf and had to be custom made.

It would be extremely difficult to broach this keyway at such a length, which makes it perfect for the wire EDM. Our wire EDM can cut a keyway up to 5.5 inches thick at sub 0.0005" accuracies.

This part was also wire cut on the outside to be perfectly concentric to the bore, for a one off piece it came to $180. For just the bore it would have been $80. Multiple pieces would be given a discount.

There are no setup or programming costs and the bonus is this part can often be turned around the same day.

We can source material or customer can source their own.

Machining cost is $28.50 each with a minimum of 20pcs. That is inner machined, outer machined and welding together, a complete post.

Custom lengths available from 6 to 96 Inches

We have the capacity for 100pcs per day often with turn arounds in less than a week,

Posts are typically 3" in diameter, however 2.5IPS (2.875" diameter) is often a much more cheaper alternative.

These push piers are a low profile solution to providing or increasing current foundation support. This system allows the user to work in tight spaces without the need for heavy machinery equipment.

The multiple piers are pressed into the ground until a specific force is achieved, hydraulic systems and mounting plates available on further request.
