A process of putting rifling in a barrel.
Surfacing or broaching.
The word broaching has to do with metal working. The inclusive definition and meaning can be somewhat on the complicated side unless you have a well - rounded working knowledge of tools and die parts. A broach is a tool with teeth and it clears away material. So broaching is the use of this tool. It is used in work where accuracy and exact precision is required.
Rotary broaching tools are used to precision cut internal polygon forms. This method is becoming very popular and has made appearances in the medical, automotive, aerospace, and plumbing fields.
Neither the tool or the workpiece rotate
A broaching tool - or a reciprocating machining process such as a shaper, see the link in the resources below.

General machining processes include turning, shaping, milling, drilling, sawing, abrasive machining, and broaching.
Rotary Broaching is a method of producing both internal and external forms fast and accurately on the end of a workpiece. Rotary broaching makes it possible to very accurate forms within 0.0005 inches within seconds. With rotary broaching not only can you produce standard shapes such as hexagons and squares but also shapes such as Double Hex Rotary Broaches, 6-Lobe Rotary Broaches, Serration Rotary Broaches, J500 Rotary Broaches, Spline Rotary Broaches, Involute Rotary Broaches, Torx Rotary Broaches, Double D Rotary Broaches and any other Special Design Required. Rotary broaches can be made to just about any size, English or Metric. Some of the material that can be rotary broached is brass, aluminum and steel and can go as much as 2 inches deep.
Difficult conversations with employees can involve broaching awkward topics around them. These could include explaining reasons for retrenchment or settling disputes.
You can find great videos on how the rotary broaching process works at Polygon Solutions website.Rotary Broaching, also known as Wobble Broaching, is unlike the conventional broaching method. The conventional method has a sequence of polygon forms that increase in size and are pushed through a hole until the desired form size is achieved. Rotary Broaching can achieve this in one pass by cutting the full form, one corner at a time, without the need for a secondary operation. This works exceptionally well on Horizontal or Vertical Spindle Machines such as Lathes, Mills, etc.Rotary Broaching is a precision method for producing internal polygon forms at an extremely fast rate. The entire operation can be completed within seconds and can produce forms to 0.0005" accuracy or better. This advanced engineering has caused Rotary Broaching to become increasingly popular; especially in the medical, automotive, aerospace and plumbing industries.There are only two necessary components that achieve the Rotary Broaching process: 1) A Rotary Broach Tool Holder 2) Rotary Broach. The principle that makes this process work is the 1° angle of the cutting tool to the centerline of the work piece. This causes the Rotary Broach to shear into the work piece, with a chisel or scalloping effect, as the broach is fed into the part to the depth required. The Rotary Broach Tool Holder has a live spindle that holds the broaching tool, allowing the spindle to spin freely within the Tool Holder. It is then driven by contact with the rotating work piece. Our Rotary Broach Tool Holders are adjustment-free so there is minimal setup required and include such features as sealed bearings which require no routine maintenance and a pressure relief hole that allows air and fluid to freely escape.With Rotary Broaching it is possible to broach such forms as:⊕ Hexagon⊕ Square⊕ Torx⊕ Serration⊕ Keyway⊕ Double Square⊕ Double D⊕ Double Hex⊕ Involute⊕ Spline⊕ Spur Gear⊕ J500⊕ Other Polygon FormsThe two most common forms are hexagons and squares. Standard broach tools are made from M-2 High Speed Steel, but may also be produced from harder material such as M-42, PM T-15 or PM M-4 HSS. Coatings such as Titanium Nitride, Titanium Carbo-Nitride or Titanium Aluminum-Nitride can be added to produce additional strength, longevity and durability.These forms can be broached in aluminum, brass, steel, titanium,plastic and other materials at a depth of up to 2 times the diameterof the broach.Rotary Broaching is the most superior method used to get a polygonform into the end of a part without the need for a secondary operation.
