A Total Guide into Plunging and Ramping | HSM Machining
Here is a neat trick to avoid chips from wrapping around your End Mill: shift your Pilot Hole in such a way, that the drilled hole is tangent to the circumference of the end mill: This method plays well when you have to make a counter-bore on a hole, that you had to make anyway. Alternatively You can also use pecking motion to break the chips.
Line Boring Equipment: A Boring Subject?
Line boring will also be required if the original main bearing caps are replaced with stronger aftermarket caps, or the block is being converted from two bolt main caps to four bolt main caps. For best results, four-bolt main caps should be machined in three-steps. ... BHJ sells a "LBF-1" Line Boring Fixture that fits on a Bridgeport mill for ...

Gun Drilling & BTA Drilling: Ultimate Deep Hole Drilling
Anthony Fettig, CEO of UNISIG, says the dividing line is at about a 40:1 depth to diameter ratio. That's the point where purpose-built deep hole drilling machines start to have a significant performance advantage over using gun drills on conventional lathes and milling centers. Even so, gun drilling on an ordinary lathe can still be effective.
Machining Fundamentals: Introduction to Milling Tools
Here we have an introduction to milling tools, where we'll explore the different types of cutting tools that can be used for milling purposes, when it's best to use these tools, and how to use them inside of Fusion 360. In this video, we show two of the more commonly used milling tools: a Flat End Mill and a Ball Nose Mill.

This kinds of boring machine combines the advantages of the vertical boring mill and the turret lathe. A vertical boring machine of smaller size is known as vertical turret lathe. It has an index able turret mounted upon the cross rail over the table for different tooling. The machine is suitable for boring and turning rail road wheels, piston ...
Boring With End Mill?
I needed a 0.590" hole in the center, for the shaft, but my biggest drill was 1/2". My boring bar starts at 3/4". I considered making a smaller boring bar, but it sounded like a lot of work. Here is my brilliant solution. I drilled a 1/2" hole. Then I lowered a 1/2" end mill into it. I milled the hole while turning the aluminum on the rotary table.
Ten Things You Need to Know about Circle Segment Milling
In this specific example, it is essential to note that the ball nose end mill took approximately nine hours and 36 minutes to complete. In contrast, the circle segment end mills took an estimated machining time of only one hour and 10 minutes. This accounted for an 88% reduction in machining cycle time. 2.

Make sure the motion path is clear. Stay away from the spindle, machine table, and tool changer. Press POWER UP. After the first POWER UP, the axes move toward their home positions. The axes then move slowly until the machine finds the home switch for each axis. This establishes the machine home position.

Holier than Thou: Precision Holes by Drilling, Boring, and Reaming
A big advantage of tubular ID mics is that a single kit can cover a wide range of diameters. This set, for example, can measure from 1.5 inches to 12 inches, or 40 mm to 300 mm, but other sets are available that measure up to 60 inches, or 1500 mm. Tubular ID mics are accurate to about one thou, or 25 microns.
