The basic process of cutting gears on a horizontal milling machine:
- The operator makes sure the machine is off and leaves it off at this point. He also checks the coolant and oil levels and cleans the machine if necessary.
- The milling machine head is removed and the overarm is extended over the bed.
- A milling cutter (selected according to the profile of the gear tooth) is installed on the arbor and centered with spacing sleeves. It is then inserted into the spindle and fastened.
- An arbor support is slid into the overarm and over the arbor, then fastened.
- On the table of the milling machine, a dividing head is placed and fastened to the bed (to the left of the arbor and its chuck facing toward it). The billet (workpiece) to be cut into a gear is gripped in the chuck of the dividing head. The dividing head is locked.
- The operator makes sure no feed levers are engaged and the spindle is in neutral.
- The machine is switched on, started and warmed up.
- After the machine is ready it is stopped and the correct speed and feed for machining the gear is selected.
- Before starting the machine, the table is moved so the workpiece is below the cutter and the workpiece is centered to the cutter along its Y-Axis.
- The machine is started again and the operator touches the workpiece with the rotating cutter then zeroes the Z-Axis dial on the vertical feed crank.
- The table is moved to the left along its X-Axis so the workpiece clears the cutter and the table is lifted a few millimeters for the first cut.
- Coolant is turned on and the X-Axis feed is engaged towards the cutter enabling the cutting of the gear groove.
- When the groove is complete, the table is lowered and moved to the left again to clear the cutter, then lifted to the same amount as the last cut.
- The dividing head is indexed and rotated to the next groove position, locked, and the cutting process is repeated until all the grooves are cut. This process can be repeated several times depending on the depth and size of the gear grooves and only a fraction of a millimeter will be left for finishing.
- The operator will ensure the cutter is still sharp and in good condition before commencing with the finishing cuts.
- A pre-finishing cut is taken and the groove depth and profile is measured. If all is fine, the table is lifted to the final cut depth and the cutting process is repeated until the gear is finished.
- Once the gear is removed from the machine, the sharp edges are removed.
The above method is just a basic explanation of how the operation is achieved. Operating any machine tool without proper training is not recommended and could lead to serious injury!

What is the difference brtween vertical milling machine and horizontal milling machine?
A "horizontal maching center" has a horizontal spindle. With a horizontal spindle, tools stick out the side of the tool holder and cut across the side of a part (workpiece). Horizontal machining centers are far more expensive than equivalent capacity vertical machines, but have several advantages. Usually the tool holder of a horizontal machine is more ridgid. Also,when machining the side of a part, metal chips fall out of the area being cut, leaving an uncluttered cutting area.A "vertical machining center" has a vertical spindle. With a vertical spindle, tools stick straight down from the tool holder, and often cut across the top of a part. One disadvantage of vertical machining is that when tools cut across the top of a part, the metal shavings, called "chips," often pile up around the tool and interfere with the cutting action. However, vertical machining centers are more common, primarily because they are less expensive than equivalent capacity horizontal machines.
Which process cannot be used to produce external threads?
It cannot be produced by Milling machine...where it can be done by Forming and Rolling and turning methods..
What are the responsibility of a milling machine operator?
A milling machine operator is responsible for setting up, operating, and maintaining milling machines to produce precision metal parts according to specifications. They interpret blueprints and technical drawings, select appropriate tools, and adjust machine settings to ensure accuracy. Additionally, they monitor the machining process, perform quality checks on finished products, and make necessary adjustments to maintain optimal performance. Safety and cleanliness in the work area are also key responsibilities.
What is embedding process?
embedding is the process of casting the tissues in paraffin wax and allowing them to facilitate cutting sections. this process is done by using the embedding machine.
How do you use a stika machine?
To use a Stika machine, start by designing your artwork or text using compatible software, such as Roland's CutStudio. Once your design is ready, load the appropriate vinyl into the machine and ensure it is correctly aligned. Then, send the design to the Stika for cutting by connecting it to your computer and selecting the cutting options. After the cutting process is complete, carefully weed out the excess vinyl, and your design is ready for application.

What is the function of column on a milling machine?
The column on a milling machine serves as the main support structure, housing critical components such as the drive mechanism and motor. It provides stability and rigidity to the machine, ensuring precise milling operations. Additionally, the column often supports the vertical movement of the milling head, allowing for adjustments in cutting depth and positioning of the workpiece. This design enhances the overall accuracy and efficiency of the milling process.
Use of milling machine?
A milling machine is usually capable of cutting a wide variety of metals, ranging from aluminum to stainless steel. Depending on the material being cut, the machine can be set to move at a faster or slower pace. Softer materials are generally milled at higher speeds while harder materials usually require slower speeds. In addition, harder materials often require smaller amounts of material to be milled off at one time.
Define universal milling machine?

What is upmilling and downmilling?
Upmilling and down milling are also known as conventional milling & climb milling. the process in which the cutting tool cuts the material and forms a chip which is big in the starting and thin in the end is known as climb or down milling. The figure is self explanatory. Upmilling or Conventional milling
What machine component on the manual mill is parallel to the Z axis?
On a manual mill, the component that is parallel to the Z axis is the spindle. The spindle is the part of the machine that holds and rotates the cutting tool, allowing for vertical movement along the Z axis during machining operations. It plays a crucial role in the milling process by facilitating precise cutting and shaping of materials.
What does a key cutting machine do?
