CNC-controlled lathe for valves (PDM)

EFCO features a stationary CNC lathe for fittings (PDM) designed for precision machining of valves, gate valves, and similar components. Our experts utilize the vertical design to enable controlled machining of sealing surfaces, radii, and tapered areas. The stationary vertical CNC lathe for fittings is therefore particularly well-suited for valve machining and valve repair.

Our engineering team integrates the machine with predefined machining sequences and a tiltable precision table. As a result, the CNC lathe for fittings enables reproducible machining of workpieces up to 600 millimeters in diameter and weighing up to 500 kilograms.

Our stationary CNC lathe for fittings features a vertical machining axis and controlled CNC sequences. Our engineering department specifies the machining of sealing surfaces, radii, and tapers. The CNC lathes for machining fittings thus perform defined cuts in a controlled manner and maintain a stable workpiece position.

Our technicians align the tilting table with the respective valve and check the clamping position before starting. This allows the CNC lathe to precisely machine components with a machining diameter of up to 600 millimeters. The stationary CNC lathe (PDM) thus also supports valve seat machining and valve overhauls.

Our stationary CNC lathe for fittings (PDM) is particularly well-suited for gate valves, valves, check valves, and gate wedges—especially when rotationally symmetrical sealing surfaces require precise machining. Our application engineers at EFCO evaluate the geometry, clamping requirements, and necessary turning operations for this purpose. This allows the PDM lathe to be specifically used for valve machining and sealing surface machining.

Depending on the component, our stationary CNC lathe for fittings performs axial, radial, and conical machining operations. Our engineering team determines the machining sequence to suit the specific valve. In this way, the CNC lathe for machining fittings supports controlled machining during repair and overhaul.

The vertical machining axis of our stationary CNC lathe for fittings (PDM) reduces deflection of the boring bar at great working depths. This keeps the tool better aligned with the workpiece surface and makes machining more controllable.

Our experts use this configuration especially for sealing surfaces on valves and gate valves. For our CNC lathe for valves, the vertical arrangement improves the conditions for consistent machining results. The design demonstrates its practical benefits especially when the height below the turning head is up to 650 millimeters. As a result, our stationary CNC lathe for fittings offers a stable solution for demanding valve and fitting work.

Our stationary CNC lathe for fittings from EFCO offers clear clamping ranges for various fitting geometries. The precision tilting table can securely hold workpieces with a clamping diameter of up to 700 millimeters and a weight of up to 500 kilograms. The usable machining diameter ranges from 80 to 600 millimeters.

Our project engineers take these limits into account right from the design phase of the clamping setup. This allows the PDM lathe to be used specifically for valve body machining and valve seat machining. Even with varying component sizes, our stationary CNC lathe (PDM) thus provides reliable conditions for precise machining processes.
