P&S Manufacturing specializes in precision multi-axis milling using advanced CNC vertical machining centers, including 4-axis and 3-axis machines. This capability enables complex multi-face machining with high positional accuracy and surface finish, suitable for intricate metal and plastic parts across diverse industries.

Machining encompasses a variety of manufacturing processes aimed at shaping and removing material from a workpiece. This includes both computer-controlled processes, such as CNC milling, turning, and routing, as well as non-traditional methods like Electrochemical, Chemical, and Photochemical Machining.

CNC Machining

Performs 3-axis milling with programmable 4th-axis indexer for multi-face machining in one setup (non-simultaneous).

4-Axis CNC Milling (Indexing)

Performs simultaneous rotary-axis milling to trim complex cast-part geometries in a single setup, improving accuracy and cycle time.

4th-Axis Milling

3-Axis Vertical Machining uses a vertical-spindle CNC mill with linear X-, Y-, and Z-motions to produce prismatic parts, slots, pockets, drilled holes, and 2.5-D contours. Tool changers, rigid tapping, and on-board probing enable accurate, repeatable machining of small- to mid-sized components with positional accuracy to ±0.010 mm and surface finishes to Ra ≤ 0.8 µm.

3-Axis Vertical Machining

Precision Multi-Axis Milling

Expertise in CNC turning using computer-controlled lathes to produce precision cylindrical components with tight tolerances. Includes capabilities such as live tooling, sub-spindle part transfer, and bar-feed automation for efficient production of complex geometries in metals and plastics.

CNC Turning uses computer-controlled lathes to rotate bar, billet, or cast blanks while single-point cutting tools remove material. The process excels at producing concentric OD/ID features, tapers, threads, grooves, and complex contours with tight positional accuracy. Modern CNC lathes support live tooling, Y-axis interpolation, sub-spindle part transfer, and bar-feed automation—enabling complete, high-volume production of precision cylindrical components in metals or plastics.

CNC Turning

Large-Diameter CNC Turning focuses on parts whose swing exceeds standard lathe capacity—typically 330 mm (13 in) or more. Specialized heavy-duty spindles and wide-gap beds allow accurate rough- and finish-turning of large flanges, rings, and housings while maintaining concentricity and surface finish comparable to standard CNC turning.

Large-Diameter CNC Turning

Hard Turning in CNC Turning refers to the process of cutting materials that are hard, typically above 45 HRC, using a single point cutting tool. It is an efficient and cost-effective alternative to grinding for achieving precision dimensions and surface finishes on hard materials.

Hard Turning

Precision turning of slender shafts whose length-to-diameter ratio typically exceeds 15:1. Uses between-centres support (live/dead centres, programmable steady rests) and vibration-damped tooling to maintain ≤0.05 mm TIR over metre-scale workpieces. Typical applications include power-generation rotors, down-hole drilling mandrels, aerospace actuators, and automotive drive shafts.

Long-Shaft CNC Turning

Swiss Machining is a high-precision CNC machining process designed for producing small, complex parts with tight tolerances. It is typically performed on Swiss-type lathes, which utilize a sliding headstock and a guide bushing to minimize deflection and enhance precision during various machining operations, including turning, milling, and drilling. Key features include high precision and accuracy, capability for multiple operations, and minimal tool deflection. Common applications include medical devices, aerospace components, precision instruments, and electronics parts.

Swiss Machining

Screw Machining is a high-speed, precision machining process designed for the mass production of small, intricate components such as screws, bolts, and other threaded parts. Performed on automatic screw machines, it allows for multiple operations—including turning, threading, drilling, and knurling—in quick succession. This ensures efficient and accurate production of high-volume parts. Typical applications include automotive components, medical devices, electronics hardware, and various fasteners or fittings.
