Which horizontal boring Mill utilizes a table that moves on a cross slide at 90 degrees to the spindle
Planer table
Which type of horizontal boring Mill is generally used for large work
Travelling column
What is the most notable advantage of a vertical boring Mill
Heavy work sits on the faceplate using gravity to help keep the workpiece secure
Parts of a vertical boring Mill five of them
Column, crossrail, saddle, Ram, tool holder and turret
What is the most common type of boring head
Offset boring head
What are the parts of the outboard supports on a horizontal boring Mill
Elevating screw, guideways, lockways, bushing or plain bearing, Vernier scale
What is the accuracy on a Vernier scale on a spindle head
.001 inches
When line boring with a line boring bar how do you adjust the tool
Using a dial indicator
What happens to the boring bar during critical measurements
It must be removed
How can taper cutting be done
With a telescoping tool holder and a boring head
How do you taper turn the OD
But by inverting the tool bit
When gang Milling on a horizontal Mill what needs to be added for the multiple Cutters to be set up right
Proper spacing
Side tool head attachment on a vertical boring Mill does what
Moves vertically along the column and side of work
Allows for more rigid set up when OD turning
No need to extend out tools and lose rigidity
How is facing accomplished on the horizontal boring Mill
Tool can be fed with the saddle/crossrail
Ram is hand-fed down for depth of cut
