Precision Horizontal Machining Center For Valve Rear Axle Flange Water Pump

As a core technical equipment in the field of high-end CNC machine tools, the Precision Horizontal Machining Center, independently developed by Jinan First Machine Tool Co., Ltd., features outstanding technical characteristics such as high precision, high reliability, and high rigidity. It is specifically tailored for the precision and efficient machining of key components in industries like valve manufacturing, automobile parts production, pipeline engineering, water pump manufacturing, and reducer production—successfully replacing imported equipment with its international advanced technical level.

The technical strengths of this Precision Horizontal Machining Center are precisely aligned with the demands of machining valves, automobile rear axles, flange fittings, water pumps, and reducers:

1. Superior Precision for Tight Tolerance Requirements With a turntable positioning accuracy of ±20″ and repeat positioning accuracy of ±6″, the machine ensures strict control over machining errors. Equipped with a BT50 milling spindle (0-750 r/min) and gear transmission, it guarantees the coaxiality of valve stem holes, the flatness of automobile rear axle mounting faces, and the hole position accuracy of flange fittings—critical for ensuring assembly performance and leak-proof or load-bearing stability of the finished components.
2. High Rigidity for Heavy-Duty Cutting Scenarios Adopting a double rectangular guide rail design, the machine boasts exceptional overall rigidity to withstand multi-directional cutting forces during heavy-duty machining. This is particularly valuable for processing thick-walled water pump housings and reducer casings: it minimizes vibration-induced dimensional deviations, ensuring the structural strength of workpieces and the smooth operation of internal moving parts (e.g., reducer gears).
3. Flexible Configuration for Diverse Machining Needs The machine offers versatile optional configurations to match different component types:
   • Turntable indexing (90°--1°--0.001°) supports multi-angle machining, ideal for valve bodies (needing inclined seat machining) and automobile rear axles (requiring multi-face drilling).
   • Tool magazines (10-tool, 24-cap, or 24-disc options) enable automatic tool switching, fitting the multi-process demands of reducer casings (milling, drilling, tapping) and flange fittings (hole drilling + end face milling).
   • Protection types (non-protection, semi-protection, full-protection) adapt to workshop environments, from clean valve production lines to dusty reducer manufacturing workshops.

This machine is dedicated to solving machining challenges of valves, automobile rear axles, flange fittings, water pumps, and reducers—becoming a core asset in related production lines:

1. Valve Manufacturing: Precision Machining of Valve Bodies & Seats It processes valve bodies (gate valves, butterfly valves) and valve seats. The X/Y/Z axis strokes (1800/1600/1100 mm) cover most valve sizes (DN40-DN300), while the high spindle precision ensures the coaxiality of valve stem holes (≤0.05 mm) and the flatness of valve seats (surface roughness 6.3). This prevents valve leakage and ensures smooth opening/closing operations.
2. Automobile Industry: Machining of Rear Axle Components It targets automobile rear axle housings and mounting brackets. The 1300*1300 mm turntable accommodates large rear axle workpieces, and the 22 KW spindle servo motor provides sufficient power for cutting high-strength steel (used in rear axles). The turntable’s flexible indexing enables simultaneous machining of mounting holes and positioning grooves, ensuring the rear axle’s load-bearing capacity and alignment with the chassis.
3. Pipeline Engineering: High-Precision Flange Fitting Machining It processes flange fittings (PN1.6-PN10 pressure ratings). The machine’s repeat positioning accuracy (±6″) guarantees consistent flange hole spacing (error ≤0.2 mm), avoiding assembly misalignment in pipeline systems. The double rectangular guide rails ensure smooth end face milling, meeting the sealing requirements of flange connections (no fluid leakage).
4. Water Pump Manufacturing: Machining of Pump Housings & Impeller Seats It handles water pump housings (centrifugal pumps, submersible pumps) and impeller seats. The spindle center-to-worktable distance (180-1600 mm) adapts to different pump housing heights, while the gear transmission delivers stable torque for boring impeller seats—ensuring the coaxiality of the impeller and pump shaft (≤0.1 mm) to prevent pump vibration and improve efficiency.
5. Reducer Production: Machining of Reducer Casings & Gear Mounts It processes reducer casings (helical gear reducers, worm gear reducers) and internal gear mounts. The 24-tool magazine supports automatic switching between milling cutters (for casing end faces) and boring tools (for bearing holes), completing multi-process machining in one setup. The machine’s high rigidity ensures the parallelism of bearing holes (≤0.08 mm), guaranteeing smooth gear meshing and reducing reducer noise.

The machine integrates five key systems to support reliable machining:

• Mechanical System: Includes double rectangular guide rails, a BT50 milling spindle, and a 1300*1300 mm turntable—providing a stable foundation for heavy-duty and high-precision machining.
• Electrical System: Optional CNC systems (Guangshu, Kandy, New Generation) paired with X/Y/Z/B-axis servo motors (30/30/30/18 Nm) enable precise motion control and program execution.
• Measurement System: High-precision sensors monitor real-time machining positions, ensuring compliance with tolerance requirements for components like valve seats and reducer bearing holes.
• Hydraulic & Pneumatic Systems: Power automatic tool changes and turntable indexing, ensuring smooth and fast responses for batch production.

Due to its complex structure, maintenance requires:

• Advanced testing equipment (laser interferometers, ballbars) to calibrate spindle precision and guide rail parallelism.
• Technicians with expertise in mechanical design, hydraulic debugging, and electrical repair—regularly inspecting guide rail lubrication, spindle runout, and hydraulic system pressure to prevent unexpected downtime.

The Precision Horizontal Machining Center, with its independent R&D capabilities and scenario-specific design, has become an indispensable tool for machining valves, automobile rear axles, flange fittings, water pumps, and reducers. It not only replaces expensive imported equipment but also enhances the precision and efficiency of domestic component production—providing solid support for improving product quality and competitiveness in related industries.
