Machine Tools

They used Bronze Copper Jade and Ivory tools.

A packing puller, hook or pick is a device that looks like a corkscrew on the end of a rigid or flexible shaft. They are made of different sizes to fit between the shaft and casing of a stuffing box of various size pumps and valves. The screw is twisted into the soft packing and then it is pulled out of the stuffing box. A packing pick is one of three tools that look like dental picks for removing leftover scraps of packing or for getting into tiny valve stuffing boxes.

the spindle of a CNC machine rotates the cutting tool.

Things to look for are machining, castings and forging ability, lead time reduction, close machine tolerances, standardized procedures and types of materials used.

A coolant is used to keep the tool tip cool. Keeping the tool tip cool prolongs the life of the tip ensuring the accuracy and consistence of the machined component.

Coolants are mixed with water and are anti-corrosive. If correctly mixed, it will not cause corrosion to any of the machine's parts.

If you are using a probe to set offsets, plug your probe results from Fanuc point probing macro G65P9100. Values from this macro are placed in the following variable by the point probing macro: #125 for X, #126 for Y, and #127 for Z. These can be used to set your G55 thru G59 offset directly or the values can be stored in #900 series write-able variables for doing calculations such as averaging, checking squareness, flatness, etc... The variables that set G55 are as follows. Example for X #5241=#125, for Y #5242=#126, for Z #5243=#127. Add 20 for each coordinate offset after that, IE: #5261, #5262, #5263 for G56, #5281, #5282, #5283 for G57 and so on.

Lathe tool dynamo meter is a equipment which used for observing the amount of load acting on the tool while operation.

2-D Lathe Dynamo-meter measures the horizontal & vertical component of the load acting on the tool.

It works on strain gauges resistance change principle.

There is a Wheatstone Bridge whose one resistance connected to the strain gauge.

In the Display unit it has PU1 & PU2 knobs.

PU1 related to the Vertical load and PU2 related to the Horizontal loads.

Most metal auto body parts

Tails tock sleeves are used on CNC lathes. It is the equivalent to a tail stock quill on a center lathe but in this case it uses hydraulic pressure to move it in and out of the tail stock.

The function of both tail stock sleeve or quill is to clamp the workpiece by means of a center that is inserted into the sleeve or quill. On a center lathe it is used for drilling also but not on a CNC lathe.

A footstep bearing is essentially a cast-iron block with a gunmetal bush that has a hollow collar fitted on its top. This bearing is used to keep the shaft upright in a vertical position. The shaft is fixed in place and not allowed to rotate by a pin.

The split nut, also known as half nut enables thread cutting on a lathe. It is engaged around the lead screw (which is housed in the apron attached to the saddle) and moves the saddle in the required direction at the required pitch.

Automated machine tools are more commonly known as numerically controlled (NC) machine tools.

The two factors that determine the size of a lathe are the "swing" and "distance between centers". The swing of a lathe is the length measured from the center of the hollow spindle or chuck to the nearest part of the bed multiplied by two. Distance between centers is the distance measured between the chuck and tail stock.

The W-Axis on a milling machine is the quill travel. The quill is located in the head and houses the cutting tool.

The AR-15 was a further development from scaling down the AR-10 rifle. Eugene Stoner designed the AR-10, but L. James Sullivan was primarily responsible for the development of the AR-15 from the AR-10.

Yes. The Gravograph IS700 is considered an CNC machine as it is ultimately controlled by sets of commands from a computer.

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.

For drilling in a lathe, "Drill Sleeves" also known as "Drill Quills" are used and they are set into the tail stock quill for drilling operations.

No. Machine tools use cutting tools to perform its operations.

Lathes can be a small as 40mm swing x 100mm between centers and up to 4.8m swing x 38m bed. There might even be smaller or bigger lathes in existence though.

An American style tool post is a square tool post designed for a center lathe. It can be rotated, is square and dove-tailed on all four sides. The dove tails allow tool holders with cutting tools clamped in it to be inserted and locked in place. This style of tool post decreases production time due to its ease of function and preset tool center heights.
