Double-cavertical deep hole drill realizes automatic tool change and improves processing efficiency by 50%

In the field of deep hole processing, the continuous operation capacity and tool change speed of the equipment directly affect the production pace. The traditional vertical deep hole drill mostly adopts single tool magazine design. When facing multi-process processing, frequent manual intervention or single tool magazine tool change waiting often become the bottleneck restricting the efficiency. Through the innovative dual storage tool magazine and automatic tool change system, the double tool magazine vertical deep hole drill processes the machining and tool change actions in parallel, making it possible to improve the machining efficiency by 50%, providing a better solution for batch production and complex workpiece machining.

The core advantage of double tool magazine vertical deep hole drill comes from the design logic of "double storage+intelligent scheduling". The equipment is equipped with two independent tool magazines, each of which can accommodate 10-20 tools of different specifications, covering various processing requirements such as drilling, boring and reaming. When the tools in one magazine are being processed on the spindle, the other magazine can complete the preparation and positioning of the tools required for the next process in advance. This parallel operation mode completely changes the discontinuous process of traditional single tool magazine "process-station-changing-remaching-tool change", and compresses the tool change time to less than 1/3 of the traditional mode. For example, when machining the hydraulic oil cylinder with stepped holes, drill, boring cutter and reamer shall be used successively, and the single tool magazine equipment shall be shut down for tool change in each process, with a total time of about 15 minutes; While the double tool magazine equipment can complete the presetting of the boring tool by another tool magazine when the drill is processed, the processing switch only takes 2-3 minutes, and the processing time of a single workpiece is significantly shortened.

The stability of automatic tool change system is the key guarantee for efficiency improvement. The system consists of mechanical arm driven by servo motor, tool position detection sensor and control system. The mechanical arm adopts lightweight design, and the positioning error is controlled within a small range to ensure the stability and reliability of the tool loading and unloading process; The sensor identifies the model and wear state of the tool in the tool magazine in real time to avoid wrong installation or use of unqualified tools; The control system automatically generates the tool change sequence according to the processing drawings, and sends commands during the process conversion to complete the fast switch of tools. When an auto parts manufacturer introduced the equipment to process the deep hole of engine cylinder, the rework rate caused by tool change error was reduced by about 30%, which indirectly reduced the material waste and labor loss.

The dual magazine design also provides flexibility for continuous machining of complex workpieces. For the precision die deep hole machining requiring more than ten kinds of tools, the traditional equipment requires multiple manual tool compensation or tool magazine adjustment, which not only interrupts the machining process, but also may introduce errors due to human operation. The double magazine vertical deep hole drill can load all required tools at once, and realize continuous machining without human intervention through program presetting. When a mold factory uses this equipment to process injection mold cooling holes, the single-shift output is increased from 80 pieces to 120 pieces, and the hole position consistency is improved, and the adjustment workload in subsequent assembly is reduced. This mode of "one-time clamping and whole-process automatic" is especially suitable for flexible production scenes of multiple varieties and small and medium-sized batches.

In addition to directly improving processing efficiency, the dual tool magazine vertical deep hole drill also brings multiple added values. During the operation of the equipment, the tool magazine can monitor the tool life in real time. When it is detected that the tool wear is close to the threshold, it will automatically send an early warning and prepare the standby tool to avoid the processing interruption caused by the tool failure. At the same time, the dual storage design reduces the pressure of full-load operation of the tool magazine and prolongs the maintenance period of the equipment. Using data from an aerospace component supplier shows that the effective operating time of the equipment has increased from 65% to 85%, significantly improving the overall equipment efficiency (OEE). In addition, automatic tool change reduces the frequency of manual contact with the tool, reduces the risk of operator being injured by high-speed rotating parts, and improves the production safety environment.

With the continuous upgrading of production capacity and quality requirements in the manufacturing industry, the application scenarios of vertical double-tool library deep-hole drill are expanding. Its high-efficiency and stable characteristics have been verified in the fields of new energy battery case deep hole processing, ship engine cylinder liner processing, etc. In the future, combined with the tool wear prediction algorithm and the Internet of Things technology, the equipment is expected to realize intelligent scheduling and remote monitoring of tools, further releasing the production potential. For enterprises pursuing lean production, this kind of innovative design that converts "waiting time" into "effective processing time" undoubtedly provides strong support for improving market competitiveness.
