cnc, castings, gear cutting

Dear All, I am 75 with 45 years in casting, machining cnc retrofit, cnc work. Studied in the UK in 1966 to 70 and back at home from 1971 without troubling old Blighty. Can give my aqquired junk knowldge. Helical gear cutting free software link, induction hardening, case hardening, castings of ferrous and non ferrous, how to retrofit a cnc with centroid cnc , special tooling tips for boring grooving etc etc

.

Welcome aboard ... and yes please !!

Welcome to the forum Vasantha,

First I will give a tip on helical gear cutting. My cnc machine, 4 axis mill, I fitted a ttothe alu rim round the divider plate and a timing belt on a servo motor with encoder. The counts per rev was fed to the computer. I grind an end mill to suit the teeth form ( need good practice) then use a small softwar for calculating how much degees to turn in how much X axis movement. If any one can contact me on email [email protected], I can send the zip file.

you can use an end mill ground to the shape of the tooth ,on vertical spindle virtically placedand fed down ie Z axis feed

or

cutter of standard module or DP fitted again to the virtical spindle but fed from a side ( ie fed on Y axis)

You have to enter the number of teeth, X axis distance, angular movement and then auto generates the G Codes

You can even cut a spiral bevel with this software

aluminum toothed rim fitted to the divider plate on a tight fit a timing belt and then a smaller timing wheel on the drive servo motor is how to convert your dividing head to bcome a 4th axis drive. By the way I have a few centroid cnc controller fitted machines, 2 Bridgeports, one OKK, One Okegai, One Chinese, one Emco Minimil and one Emco Mini Lathe,and another mini mills of chinese origin. I also have one 25 kw Induction Heater, 60 Kw Induction Heater, 60kw medium frequency melter, and one 100 kw Induction melter. I do make many things and order book full.

I make centrifugal castings of Cylinder Liners, Bushes and all machines made by me. All pictures available on request with no expectations of businesses. This is purely give what I have learned. For example I repair Turbo chargers of any size and the bushes are made of CW713R which you can buy from company called Zabrak Metal, Turkey. The turbos will run for another couple of thousand hours. I can give the gen on it. The thrust bearings can be made of Alu, and thrust plates with MS, case hardened fianlly and polished. Pics available on request.

Further Centrifugal casting pics for vertical axis machine built by me for small bushes in Brass available.
