Shenzhen EMAR Precision Technology Co., Ltd. specializes in CNC core machining. Users often find that the service life of drill bits is often affected by external factors during deep hole machining. In this article, we mainly list the factors that affect the service life of CNC core machining drill bits, including:

(1) The performance of workpiece materials: Quasi dry drilling is more sensitive to the differential changes in workpiece materials. During the CNC Machining process, different material properties can affect the durability of cutting tools.

(2) Errores fabricationis litrorum drillum: Forma recta proprietatibus drillum et optimis fizikalis materiae succidentium habent significantiam influentiam ad succidendum functionis drillum bit.

(3) Good grinding of the transverse edge of the drill bit and the addition of oil mist grooves on the rear cutting surface can significantly improve productivity and achieve the best use effect.

(4) Influentia machinae velocitatis ambulantis: Quando temporis fertilis machinae ambulantis constantur, fortis cutationis humilior est in velocitate altissima. Sine fluctum sequitur, efficabilitate drilling meliora potest.

(5) Deviation of drill tip: The slight deviation of the drill tip caused by the jumping of the drill bit or spindle after clamping. Si fuerit magna ante processionem, crescet et diminuet vitam servitutis. To avoid hole displacement, guide holes are usually used, which will increase the service life of the drill bit.

(6) The influence of compressed air: The increase in oil mist pressure during CNC drilling has a positive effect on obtaining good lubrication for the drill tip.

(7) Raw materials: The physical properties of castings from different batches vary significantly, which greatly affects the efficiency of drilling production. Despite taking some control measures, additional stress and deformation may occur when the drill bit encounters holes, inclusions, and hardness changes. In addition, the walking machine has relatively high requirements for the external diameter and straightness of the raw materials. Therefore, the consistency between the quality of the raw materials and the interior of the materials is the foundation for efficient machining of the drill bit.

(8) Coating of cutting tools: The use of coated drill bits during quasi dry machining is an effective means of achieving high productivity. In contrast, uncoated drill bits have a relatively shorter lifespan. Melior vestimentum est vestimentum fisicam, dum diamantes similes vestimenta tantum ante faciem lapidibus et instrumentis succidentur, quam totum vestimentum. Perfectus litrorum drillum diamantes local is PVD est excellent. In fabricationibus et fabricationibus aluminium, contritio litrorum drillum maiorem causa est ab abnormale gesto et lacrima, et in aliis casibus, etiam a ligatione causa est.
