Since most countries are still in the initial stages of drill bit regrinding, most drilling operators are accustomed to using drill bits only once and are unaware that drill bits can be regrinded, or have no awareness of the need to regrind them after a certain point in the drill string. They cannot effectively control when to regrind the drill bit. Furthermore, strictly adhering to the practice of regrinding when the wear step diameter reaches one-third of the alloy column diameter requires operators to frequently check the alloy column wear, which is time-consuming and increases safety risks, making it difficult to implement in practice.
Therefore, promotion should be based on practical considerations and the current usage habits of most operators. The current promotion of drill bit regrinding is being carried out in two phases: gradually allowing operators to adapt and slowly changing their usage habits. Our most basic requirement is that the alloy column of the drill bit requiring regrinding must not be broken. Secondly, operators should replace the drill bit for regrinding when they feel the drilling speed is slow. This approach caters to operator habits while achieving the goal of significantly improving drilling efficiency and significantly reducing drill bit usage costs through regrinding.
Kaiqiu Drilling Tools Co., Ltd. has been committed to promoting the concept of drill bit regrinding to distributors and users in many countries. Drill bit regrinding reduces operating costs for users, making Kaiqiu Drilling Tools Co., Ltd.'s drill bits more cost-effective than before.
In fact, many companies and private business owners currently use drilling meters per shift as a key performance indicator. Operators, considering their working hours, also prioritize high drilling efficiency, hoping to reap the rewards of their hard work in the shortest possible time. This performance evaluation method also contributes to the promotion of drill bit regrinding. Furthermore, in certain special working conditions in China, such as overheating, rock bursts, and radiation, operators need to maximize drilling efficiency. To reduce drill bit operating costs, there is an objective need for drill bit regrinding and reuse.
Drill bit regrinding is a task that changes user habits, and its promotion is destined to be a lonely and lengthy process. As environmental protection requirements become increasingly stringent in many countries and the cost of cemented carbide increases, drill bit regrinding will inevitably become a regular practice.
Drill bit regrinding personnel can be trained and put to work quickly.
Regrinding equipment is generally not prone to breakage; the main consumable at a regrinding station is the grinding cup. The consumption of the grinding cup depends on the amount of drill bit regrinding, the degree of drill bit wear, and the operator's skill level. The regrinding machine has low operating requirements, requiring only a 380V three-phase power supply and a water source. The peak power consumption of the regrinding equipment does not exceed 6KW. Regrinding stations can be built as fixed stations or as mobile modular stations using shipping containers. Regrinding stations do not pollute the environment.
