1) How do I program my machine?

Contact the machine manufacturer or their distributor who sold it to you. The manufacturer is the best resource for programs for their machines. Many of our clients use GibbsCam or MasterCam.


2) For CNC Broaching, do I need a spindle lock?

Yes. But it is possible to lock brake in the program. Contact your machine manufacturer or distributor to find out how to program lock your spindle brake. We do not know your machine.
95% of our clients do not have a physical spindle lock but rather lock the brake with the program.


3) Can I “step-it-over” and create a wider keyway?

Yes. This is very common. But check the Depth of the Keyway Radially (DKR). Our inserts only stick up so high above the tool holder.


4) Can I get a different width tolerance on your inserts?

We can special grind the widths of both cutting edges down to different width tolerances. NOTE: this does grind the TiN coat off of the very sides which is mostly relief angle. The TiN coat is still along the whole face of the cutting edge.


5) Can I get a radius, spline shape, triangular shape, or other form on CNC Broach Inserts?

No. Unfortunately do not grind shapes or radius. But as you can see from the pic we do have clients that successfully alter our product.
Get a radius, spline shape, triangular shape


6) Will CNC Broach calculate insert life for me?

No. There are enough client testimonials for you to get a pretty good idea of what our product is capable of.


7) Will CNC Lathe Broaching or CNC Mill Broaching damage my machine?

No. Not if you follow the recommended feeds/speeds/set-up info.

Our keyway cutter is designed for a shaving style of broaching which doesn't have the same impact and shock that is associated with the older styles of broaching that take much deeper depths of cut.

At .001” DOC per pass you could push that through with your hand.


8) Does CNC Broach Tool Company provide programming?

No. For liability reasons we only offer general feed/speed and set-up advice.


9) How Do I Broach on my CNC mill or CNC Lathe with CNC Broach Tool Company?

Each job has many different factors such as material, quality of machine, and the IQ of the operator.

We offer general guidelines that you perfect for the variables of your specific job and machinery.

Depending on the material being cut , take .0005-.0015" per pass at 250-550 IPM.


10) Can I regrind your Keyway Broach Inserts?

Yes! Please do. We do not offer a regrind service but many of our clients get multiple regrinds on each cutting edge.


11) Why can’t I buy CNC Broach Tool Company Keyway Cutters through distributors?

Distributors artificially inflate the cost of tooling dramatically. How can the engineer accurately calculate true tool value when the administrative costs of the distributor are tacked on and hitting 40-50% ?

We sold through distributors when we first opened for business and found they built a wall between the client and CNC Broach Tool Company. We didn't know who our real client was and couldn't provide technical advice. We found the distributor didn't protect our brand name by making sure the client had feed/speed/set-up advice before they ran our tool for the first time.

Distributors wanted us to give them 20% discount, then they would turn around and mark it up on the client another 20-30%, whatever they could get away with. We wouldn't even know, We didn’t control the price of our own product in that situation. Which was bad for our brand and our clients.

The distributor makes their money off of turn and burn sales, volume. So they have no incentive to care and provide good service. A distributors livelihood isn't based on our 1 product.

But our family’s livelihood relies on the personal relationship we have with our clients and so as a one-product, family company, we are the only ones we trust to provide technical support and great service. Give us a call and find out.
