Key Cutters are best defined as key cutting machines. These key cutters work by cutting away and shaping the required material and are the primary method for reproducing duplicate keys. These cutters have a vice or grip and the key flat or blank is inserted and held tight in this mechanism.
The original key is fixed into a guide and then moved parallel alongside the blank, which in turn is moved against a wheel which cuts the new key. Key cutters may produce very sharp edges on the new key, and have to be deburred. This is usually achieved by scrubbing with a metal wire brush, or appropriate abrasive tool. If this deburring process is not carried out the duplicate key will catch inside the lock and could also be dangerously sharp.
The more modern key cutters of today are mostly automated and use grinding or milling equipment to produce the desired result.
There are various types of key cutting machines available and these can include:
Key copy machine
Most modern key-cutting equipment is either manually or computer controlled and most machines will incorporate the following features:
Micro-adjustment that can adjust expediently and quickly for accurate cutting depth
Equipped hand wheels
Can be artificially controlled to cut equally ensuring the cutter is under good protection
Step by step fine directive centesimal ring of the guide adjusts various cutting depths quickly and accurately
Other types of key-cutting machinery may also incorporate the following functions:
Unique rotational operating design of 6 axles and 3 cutters
Duplicates all kinds of cylindrical key and ladder-like keys with high accuracy and efficiency
Solves the problems of changing cutters and rectifies the machine during duplication
There are a vast number of different types of cutters and hand tools used in the process of key-cutting and these will include:
Ball herd end milling cutter
Woodruff key cutters
High speed steel cutter
Locksmith tool lock pick
Key-cutting does take time if its done properly and traditional shop based key cutting will usually involve a long wait and many key cutting companies will offer online services.
