Dezhou Ruifeng Machine Tool Co., Ltd.

Dezhou Ruifeng Machine Tool Co., Ltd. is a professional manufacturer of deep hole drilling and boring machines. Main products: T21 series, T22 series, ZK21 series deep hole drilling and boring machines, 2M21 series deep hole honing machines, and related cutting tools, auxiliary tools, and spare parts. T2120 deep hole drilling and boring machine, T2225, T2235, T2250 deep hole boring machines: These machines are specifically designed for processing cylindrical deep hole workpieces, such as the spindle holes of machine tools, various mechanical hydraulic cylinders, cylinder cylindrical through-holes, blind holes, and stepped holes. The machine can not only perform drilling and boring but also rolling operations. During drilling, the internal chip removal method is used, while during boring, the front chip removal method is adopted. The machine bed has high rigidity and good precision retention. The spindle speed range is wide, and the feed system is driven by an AC servo motor, which can meet the needs of various deep hole processing techniques. The oil supply holder clamping and workpiece tightening use hydraulic devices, with instrument display, ensuring safety and reliability. T2225, T2235, T2250 deep hole boring machines are specialized machines for machining cylindrical parts. They can bore through holes and stepped holes, using a push-boring method for boring and front chip removal for chip evacuation. They are suitable for both mass production and small batch production. ZK series deep hole drilling machines: These are used for deep hole drilling equipment, providing high efficiency and high precision using external chip removal (gun drilling) for small diameter holes. Through a single continuous drilling operation, it can achieve the quality typically requiring drilling, reaming, and honing processes. The hole diameter accuracy is IT7-IT9, surface roughness Ra3.2-0.04um, and the straightness of the hole centerline over 1000mm length is ≤0.05mm. It is widely used in the statue mold industry for water holes, ejector pin holes, and electric heating holes; in the hydraulic machinery industry for valves, distributors, and pump bodies; in the automotive and tractor industry for engine blocks, fuel system components, transmission system components, steering mechanism housings, and steering shafts; in the aerospace industry for thrusters and landing gear; and in the generator industry for heat exchanger plates, among other parts requiring deep hole processing. To meet the needs of a wide range of users, our company can provide various customized products, suitable for deep hole processing of various high-strength materials, such as 35Gowmn, 65Mn, 40Gr, stainless steel, mold steel, and various non-ferrous metals. Our company offers deep hole processing services for diameters ranging from Φ3mm to Φ500mm, with a maximum hole depth of over 12 meters, hole diameter accuracy up to IT7 or higher, hole surface roughness up to Ra0.2, and hole centerline straightness per meter reaching 0.05mm-0.1mm.
