Which Brand Of Drill Bits in China Has Good Stability

Kunshan Meiyaxing Hardware Machinery Co., Ltd. is a direct branch of Hong Kong Meiya International Trading Company in China. It has its own tool brand: MANF, engaged in CNC tool sales and operation services. Provide tungsten steel milling cutters, milling blades, turning blades, grooving and cutting blades, drilling and boring blades, multi-functional blades, threading blades and other indexable blades and their matching tool holders and cutter discs. And reached long-term strategic cooperation with many well-known production factories. The two sides jointly developed, designed, and produced teams, advanced equipment, and continuously innovative technical strength. They are committed to mutual cooperation, guided by technical services, and formed a form of mutual reliance in the industrial chain to solve various processing problems for processing and manufacturing companies.
1. Control the details of the drill bit
Choose the right rod material, and the hole quality has been designed from the process design Here we go. If the runout is too large, the accuracy, finish and concentricity of the hole are sacrificed. The right core thickness on the drill tip is important for the drill to remain stable as it engages the material being machined to prevent the drill from over-growing and deflecting, which can result in an oversized hole or affect the straightness of the hole.
When quality requirements include improved tolerance and finish surfaces, switching from a single to a double ligament on the drill can help.
These edges stabilize the drill by providing four points of contact in the hole and provide a polishing effect to leave a very good finish. The double ligaments also act as a guide to keep the drill straight, especially in deep holes. It prevents the drill from over-growing and wobbling, providing a relatively round hole.
While double ligament drills produce a good surface in short-chipping materials, they are more prone to sluggish cutting when the material produces long chips. Single-ligament drills are recommended when drilling. Single-ligament drills are preferred for long-chipping materials like aluminum or stainless steel. Using double-ligament stainless steel drills can cause chips to get between the contact point between the drill and the material.
Controlling runout is another key to hole quality. Too much runout will increase the diameter of the processed hole, and as the drill speed increases and rotates, it will cause the drill to drill larger and larger holes.
A drill that is too long will result in poor rigidity and vibration. These vibrations, especially those that are difficult to see with small drills, can cause the drill to break and leave broken tools on the surface of the inner hole.
2. Control of cutting fluid
Proper coolant management, including maintaining optimal coolant concentration, filtration and pressure, is critical in drilling applications.
Proper coolant concentration increases lubricity while taking away heat from the cutting edge of the drill. Filtration It can remove metal contaminants and other substances, thereby improving drilling performance and preventing problems such as coolant hole clogging in small diameter drills.
Preventing chips from getting between the drill and the wall of the material being processed is critical to the quality of the hole. The shape and color of these chips can help the operator know whether the quality of the hole made by the drill is good or bad.
It is important that the chip flute of the drill produces nice conical chips. Two or three curled or pigtailed chips may entangle in the chip flute and rub and scratch the sides of the hole. This friction will cause the surface to be rough.
The back of the chip should be silver and shiny. Unlike milling, you want to see blue (this picture only shows the chip color, not drilling chips), because it means heat is entering the chip, blue means that your hole processing means a lot of heat is generated at the cutting edge. This heat will cause the blade to wear faster.
Many times, stability is a core indicator to measure the quality of a tool, which is also the difference between large and small factories. Therefore, it is recommended that factory owners should not be dazzled by the temporary low price. After all, the time cost of everyone's investment is still very high. It is best to find a professional manufacturer as much as possible.
