What is back spot facing?
Back spotfacing is the machining of large spotfaces and counterbores without turning the work piece over, or spotfaces and counterbores that are inaccessible from the opposite side. This means that the machining is done on the same side as the drilled hole.
What is a back counterbore?
A customized automatic back boring solution for use in multiple applications.
What is the difference between spot facing and Counterboring?
The difference between counterboring and spotfacing is that a counterbored surface usually has a shoulder at the bottom of the enlarged hole, while a spotfaced surface is flat and always at right angles with the axis of the hole.
What is Spotface counterbore?
A spotface provides an accurate bearing surface for the underside of a bolt head. Counterbore. Symbol. Countersink Callouts. Countersink – To recess a hole with a conically (cone) shaped tool to provide a seat for flat head screws.
What is the difference between a spotface and a counterbore?
What is counterbore and spotface?
Spot Facing screw holes are more similar to counterbore screw holes than they are to countersink screw holes. A spotface generally takes the form of a very shallow counterbore and is used in order to provide a smooth, flat, accurately located surface.
What is countersinking and counterboring?
A countersink produces a conical hole matching the angle of the screw so that when the screw is fully engaged the head will sit flush or slightly below the surface. A counterbore is used to enlarge the opening of a hole producing a flat bottom so a socket-head screw will fit flush with the surface of the part.

How to use back spot facing tool?
No manual interruption is required at any stage, which makes the back spot facing tool most ideal for machines with auto-cycle like VMC: How it works? 1. Rotate Anti-clockwise and wind folds in. 2. While rotating in anti-clockwise direction lower the ABSF tool into the bore. 3.
What is face face milling?
Face milling with a very high feed per tooth (up to 4 mm/tooth) is possible when using cutters that have small entering angles or when using round insert cutters, due to their chip thinning effect. Although the depth of cut is limited to less than 2.8 mm, the extreme feed makes it a highly productive milling method.
