How Do You Cut A Keyway In A Blind Hole?

What type of cutter would you use to cut a blind key seat?

When a specialized cutter is used to cut the Keyseat, it’s a Keyseat Cutter. A Woodruff Cutter is a Keyseat Cutter. There are several kinds of Keys in common use.

How do you cut a keyway?

Keyway cutting with a keyseater machine (or internal keyway slotting machine) removes material through a series of tooth cutting strokes. Some keyseaters only feature a single tooth cutter, while other machines (like the Davis Keyseater) use a multiple tooth cutter to achieve cutting speeds as fast as broaching.

What is a blind keyway?

A keyway is considered blind if it stops in the middle of material. To use CNC Broach Tools you must have your blind keyway end in an appropriate groove or cross hole relief. the keyway must end “in air” Be aware that you can have a through keyway but be machining it out of bar stock.

Which cutter is suitable for making such keyway?

If you need to mate a part on a shaft, you need a key cutter. A key cutter, also known as a keyseat cutter, keyway cutter, or woodruff cutter, is a versatile tool that can be used to cut several different types of keyways.
Key Cutter Speeds and Feeds.

How do keyways work?

A key and the keyways make up a Keyed joint to secure the hub and the shaft to prevent relative movement between a power transmitting shaft and an attached component.Keyseat is a recess in the shaft and the Keyway is the recess in the hub to receive the key and thus securely lock the component.

What are cutting broaches?

A broach is a 5-sided, tapered cutting tool, used by hand much as a reamer to enlarge and align a pair of holes that will subsequently be tapped. Another example of a typical application would be to align the holes in the knuckles of a hinge before the pin is installed.

How are keyways broached?

Insert the bushing into the hole you wish to broach. It should drop in easily. Next, rotate the slot to where you wish to cut the key. Liberally lube up the broach with your favorite cutting oil and and insert the broach into the slot in the bushing.

What is Rotary Broaching?

Rotary Broaching is a precision method for producing internal polygon forms at an extremely fast rate.The Rotary Broach Tool Holder has a live spindle that holds the broaching tool, allowing the spindle to spin freely within the Tool Holder. In a lathe, the spindle is driven by contact with the rotating work piece.

What is keyway and Keyseat?

Usually the term keyseat is referred as a groove or pocket on a shaft, and a keyway is a slot in a hub in which the key fits into. The complete system is called a keyed joint (Figure 2). (Figure 2) Keys are made of varied types of materials, and also come in different shapes and sizes.

What is the function of key in shaft?

In mechanical engineering, a key is a machine element used to connect a rotating machine element to a shaft. The key prevents relative rotation between the two parts and may enable torque transmission.

What is a slotter machine?

A slotter machine is a machine tool that works on the principle of a quick return mechanism to cut metals from a workpiece. It cuts metals only in the forward stroke only. It is used to produce keyways, slots, grooves, internal and external gear profiles and etc.

Which of the key does not require keyway on the shaft?

Hollow and flat keys
They are only used for transmitting little rotary forces. For these no keyway must be made: – The bottom of hollow keys is concave in longitudinal direction. The edges of these keys resemble cutting edges which contact the shaft.

What is effect of keyway cut into the shaft?

The keyway cut into the shaft reduces the load carrying capacity of the shaft. This is due to the stress concentration near the corners of the keyway and reduction in the cross-sectional area of the shaft i.e. the torsional strength of the shaft is reduced.

How much torque can a keyway handle?

The limiting pressure point of a keyed shaft is the keyway side of the male shaft, provided the proper key material is selected. Thus, 270 Nm is the maximum torque that can be transmitted before the 19 mm diameter keyed shaft plastically deforms.
