DOUBLE ANGLE MILLING CUTTER
Material: It is made of HSSM35 material imported from Japan, high temperature quenching, hardness reaches HRC64-65, ultra-high temperature quenching, high hardness, copper key and iron key are available, good wear resistance
Production process: Using full CNC grinding machine, full grinding technology, with sharper tip and easier to cut the key. The cut key is smooth and burr-free
Suit for machine: It is suitable for all kinds of single-head and double-head key machines. It can be used by any quality machine. It does not need to change the machine and also can process copper keys and iron keys on same key machine. No longer needs to change the cutter.
Before running the machine, it is necessary to accurately adjust the cutter to ensure the key blank and the parent key are matching, and to avoid the tool being broken due to the unstable key assembly.
The cutter is clamped on the machine and the key blank and the parent key are fixed on the clamps. Do not clamp the key blank too tight. The patent key is close to the tracer and the key blank is close to the cutter. If the key blank is not fastened, the key blank should be removed and reclamped.
When the machine is not running, clamp the cutter and cut from the left-to-right to check if the position of the parent key and the key blank are uniform. If not, re-clamp again.
After the machine is running, should wait the cutter is fully rotated before cutting.
When the key blank is close to the cutter, the clamp should be held to prevent the key blank from hitting the cutter after the cutter is fully rotated before cutting. So the first cutter tip which just touched the key blank won`t be damaged by uneven force.
When start to cut the key,it should be smooth to push the clamp which fixed the key blank, so that the cutter tip won`t be damaged by uneven force.
