For years I've always wanted a milling machine but they are too expensive and I just couldn't bring myself to pony up to dosh. So I decided to make one mysel. Machine tool called a milling machine ©2002 John Wiley & Sons, Inc. Groover, “Fundamentals of Modern Manufacturing 2/e”. A slot is cut into part. This is the full manual from Hardinge, who have taken over Bridgeport’s parts, sales and service. This covers all aspects of parts, maintenance, operation.

- Jet 16 Milling Machine Manual
I use both the manual and CNC versions of the Taig milling machine and feel that they are an excellent option for the shop needing a small milling machine of low cost and high quality. The ER16 spindle allows tooling up to 3/8' to be utilized. Proudly made in the U.S.A.!
Taignow offers a ball screw option on the CNC ready and CNC mills! Thispage also has pricing for the CNC lathe versions, as well as conversionkits, etc.

AIM:
To machine gear to the given module and number of teeth in the given work piece.
TOOLS AND EQUIPMENT’S REQUIRED:
1. Milling machine
2. Vernier caliper
3. Mandrel.
PROCEDURE:
1. Calculate the gear tooth proportions.
Where,
Blank diameter = (Z + 2) m
Tooth depth = 2.25 m
Tooth width = 1.5708 m
Z = Number of teeth required
m = module
Indexing calculation
Index crank movement = 40 / Z
2. The dividing head and the tail stock are bolted on the machine table. Their axis must be set parallel to the machine table.
3. The gear blank is held between the dividing head and tail stock using a mandrel. The mandrel is connected with the spindle of dividing head by a carrier and catch plate.
4. The cutter is mounted on the arbor. The cutter is centered accurately with the gear blank.
5. Set the speed and feed for machining.
6. For giving depth of cut, the table is raised till the periphery of the gear blank just touches the cutter.
7. The micrometer dial of vertical feed screw is set to zero in this position.
8. Then the table is raised further to give the required depth of cut.
9. The machine is started and feed is given to the table to cut the first groove of the blank.
10. After the cut, the table is brought back to the starting position.
11. Then the gear blank is indexed for the next tooth space.
12. This is continued till all the gear teeth are cut.
CALCULATION:
Z = No.of teeth = 23
m = module = 2 mm
Blank Diameter = (Z + 2) *m
= (23 + 2) *2
= 50 mm
How To Win At Slot Machines
Tooth Depth = 2.25 m
= 2.25 *2
= 4.5 mm

Indexing Calculation
= 40 / Z
= 40 / 23
