What is back spot facing?

Backspotfacing (back spot facing) is analogous to backboring, meaning that the tool manages to reach to the far side of the workpiece (away from the spindle side) and cut back toward the spindle. Such back-cutting operations can obviate second operations, with their attendant setup time and part rehandling time.

Why do we use spot facing?

Spot facing: Spot facing is the operation of smoothing and squaring the surface around and at the end of a hole so as to provide a smooth seat for a nut or for the head of a cap screw. Spot facing is generally done on castings and forgings.

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 a spot face cutter?

The shape of the spot face cutter is different to that of a drill. It has a small pilot pin in the middle and then a flat cutting face. Those that are designed for cutting stripboard also have a handle.

How deep is a spot face?

Spot-Bits are available from 1/8” to 35/64” and 3mm to 14mm, and can counter-bore to approximately 1/8” deep. Sink-Bits can be made available at special angles other than 82º or 90º. Spot-Bit cutter diameters can be altered to meet specific needs. Combination Drill and Spot-facing or Drill and Countersinking Tools.

What is counter boring counter sinking and spot facing?

Countersink screw holes differ from counterbore screw holes in that they are more conical in shape and tend to be narrower. They are conical enlargements of coaxial holes. Similarly to counterboring, countersinking is used to get the head of the screw flush with or below the workpiece’s surface. Spot Facing Screw Holes.

What is spot facing operation?

Explanation: Spot facing is a machining operation for producing a flat seat for bolt head, washer or nut at the opening of a drilled hole. Spot facing is similar to counter-boring, except that it is shallower.

How are counterbores made?

The process of counterboring creates a cylindrical cavity with a larger diameter at the head of a pre-drilled hole. The pre-drilled hole is meant to contain the fastener and to prevent the two work pieces from separating when their two flat surfaces are joined.

What is a counterbored hole?

A counterbore (symbol: ⌴) is a cylindrical flat-bottomed hole that enlarges another coaxial hole, or the tool used to create that feature.

What are six boring tools?

Here are the top SIX line boring tools that experts keep on hand:

• 1 | Micro Adjust Boring Head. Operators have the ability to easily adjust the tool bit to make the bore larger.
• 2 | Bore Measuring Tool. Quick and easy way to accurately measure bore diameters and tool height.
• 3 | Digital Bore Measuring Caliper.

How does the automatic back spot facing tool work?

After the spot facing is over, take the back spot facing tool little away from the job; then reverse the spindle rotation to anti-clockwise and pull the automatic back spot facing tool out of the bore. The wing automatically folds into the pocket on coming in contact with the job in anti-clockwise rotation.

Which is the best tool for back spotfacing?

Its versatile wing replacement system makes it a cost-effective option for automatic back spotfacing applications. The Erix cutting tool’s solid dependability is ideal for situations where downtime is unacceptable. All Spindles from ø10 upwards (hole size) with cylindrical shanks are designed for Weldon fastening (DIN 1835B).

What’s the purpose of the back counter boring tool?

The rear counter boring tool is meant for producing one specific back spot facing dia through one specified bore. Therefore, these back spot facing tools are ideal for a large batch production or mass production. The below given graph shows for a particular sized hole, upto which size of back spot face can be done.

Can you back spotfacing with an Erix tool?

Deburring can be a laborious process that often involves working at difficult angles in confined spaces through the hole. up into the cutting position. When rotating clockwise, it can begin back spotfacing. rotating anticlockwise, retract the tool. If playback doesn’t begin shortly, try restarting your device.
