Kunshan Meiyaxing Hardware Machinery Co., Ltd. is a direct branch of Hong Kong Meiya International Trading Co., Ltd. in China. It owns its own cutting tool brand: MANF, and engages in the sales and operation of CNC cutting tools. It provides tungsten carbide end mills, milling inserts, turning inserts, grooving and parting inserts, drilling and boring inserts, multi-functional inserts, threading inserts, and other indexable inserts and their matching tool holders and tool holders. Furthermore, it has established long-term strategic partnerships with several well-known manufacturers, jointly developing, designing, and producing teams, utilizing advanced equipment, and continuously innovating its technology. We are committed to mutual cooperation, guided by technical services, forming a mutually supportive industrial chain to solve various processing problems for manufacturing enterprises.
In deep hole machining, precision boring, and intermittent cutting, difficult chip removal, heat buildup, and short tool life are common problems. Internal cooling water jets, through the design of high-pressure coolant channels within the tool body, precisely deliver coolant to the cutting edge, achieving a triple effect of powerful cooling, high-pressure chip removal, and lubrication/friction reduction. It's not just an added bonus, but a necessity in many scenarios.
II. When should internal cooling water jets be used? - 5 Best Times to Use a Cooling Tool
🔥 Time 1: Hole Depth Exceeds 4 Times Diameter With ordinary external coolers, coolant cannot reach the bottom when the hole depth exceeds 4 times the diameter, leading to chip blockage and burnt cutting edges.
👉 After switching to an internal water jet cutter: High-pressure water directly impacts the cutting zone, breaking up chips and allowing them to be discharged through the groove, easily machining holes 10 times the diameter or deeper.
🔥 Time 2: Chips are "Long Tendrils" or "Tangled" Long chips can entangle the tool, scratch the machined surface, and even cause automatic shutdown.
👉 Internal high-pressure water jets act like "water shears," forcibly breaking long chips into C-shaped or flake-like small chips, ensuring smooth chip removal and continuous machining without stopping.
🔥 Time 3: Burns and Built-up Edges Appear on the Machined Surface External coolers can only "drench" from the outside in, leaving the inner wall temperature still very high.
👉 Internal cooling removes heat from the hottest core area, reducing the cutting edge temperature by 50-100℃ and improving surface finish by one grade.
🔥 Situation 4: Difficult-to-machine materials (stainless steel, titanium alloys, Inconel)
These materials have poor thermal conductivity, high cutting forces, and are prone to work hardening. External cooling simply cannot penetrate them.
👉 High-pressure internal cooling forcibly reduces the cutting zone temperature, preventing work hardening and extending tool life by 2-5 times.
🔥 Situation 5: Automated mass production
Automated production lines are most vulnerable to chip breaking problems leading to "tool entanglement alarms," which is even more fatal when one person is managing multiple machines.
👉 Internal water outlet + high-pressure chip breaking ensures stable and controllable chip cutting, truly achieving "unattended" continuous machining.
III. Usage Tips
1. Start-up sequence: Turn on the coolant first, then feed when the tool tip is close to the workpiece-avoid dry cutting damage to the cutting edge.
2. 1. Higher pressure is not always better: For easily brittle materials such as cast iron and powder metallurgy, excessive pressure can actually shatter chips and damage the cutting tool.
2. Regularly check the filtration system: The diameter of the internal cooling holes is generally 0.5-2mm; once clogged with impurities, the effect drops drastically.
3. Recommended combination: Internal cooling jet + high-pressure filtration system + chip crusher → the golden combination for deep hole machining. Internal cooling jets are not a panacea, but in scenarios requiring deep holes, difficult machining, and high quality, they are an irreplaceable solution. Choosing the right tool body structure and using it under the right conditions not only extends tool life but also ensures the stability and efficiency of the entire process chain.
