Description

Technical Field

[0001] This utility model relates to the field of key CNC machining technology, specifically a portable key CNC machining machine. Background Technology

[0002] Locks are very common in daily life. Keys can be damaged or lost during use. In order to meet the demand for more keys, key duplication machines have emerged. The accuracy of the copied keys depends partly on the clamping method of the fixture and the precision of the fixture itself, and partly on the mechanical transmission part of the key processing equipment.

[0003] Existing key processing equipment mostly uses belt-controlled stepper motors for cutting, which have low cutting accuracy. Furthermore, due to the generally low motor power, keys need to be cut multiple times to meet product requirements, resulting in low key duplication efficiency. Therefore, we propose a portable CNC key processing machine. Utility Model Content
