Machined Parts Service

What Machined Parts Service?

Machined Parts Service is the process of changing the dimensions or properties of a workpiece by means of a mechanical device. The differences in machining methods can be divided into cutting and pressure machining.

Machining requires machinery by digital milling machine, digital forming grinder, digital lathe, EDM, universal grinder, machining centre, laser welding, medium walking wire, fast walking wire, slow walking wire, external grinding machine, internal grinding machine, precision lathe, etc., which can carry out the processing of precision parts such as turning, milling, planing, grinding, etc. Such machinery is good at the processing of precision parts such as turning, milling, planing, grinding, etc., which can process various irregularly shaped parts with a processing accuracy of up to 2μm.

Machined parts are mechanical parts processed and shaped with various mechanical processing equipment, mainly refers to the processing method without chemical reaction (or very small reaction). There are two main categories of mechanical machining: manual machining and CNC machining.

Manual Machining
CNC Machining

Manual machining is a method of processing various materials through mechanical equipment such as milling machines, lathes, drill presses and saws operated manually by mechanics. Manual machining is suitable for the production of small, simple parts.

CNC machining refers to machining by machinists using numerically controlled equipment such as machining centres, turning and milling centres, EDM wire-cutting machines, thread cutting machines, etc. CNC machining is used to machine workpieces in a continuous manner and is suitable for high volume, complex shaped parts.

Where you use machined parts?

Machined parts can be used in a variety of industry sectors. They are fully customisable, high-precision mechanical parts. The main industries currently in use are medical, electronics and aerospace.

How much does it cost to machine a part?

The cost of machined parts depends on the type of machine and the number of hours it runs, with different rates for different machines. 3 axis milling machines typically cost around $40 per hour, while CNC lathes can cost around $35 per hour

Technical requirements for machining

1 . Tolerance requirements

    (1) Unannotated shape tolerance should be in line with the requirements of GB1184-80.
    (2) the uninjected length size allowable deviation ± 0.5 mm.
    (3) casting tolerance zone symmetry in the basic size configuration of the blank casting.

2 . cutting processing parts requirements

(1) parts should be inspected and accepted according to the process, and only after the previous process is checked and passed, can be transferred to the next process.

 (2) The machined parts are not allowed to have burrs.

 (3) The parts after finishing shall not be placed directly on the ground, but shall take the necessary support and protection measures. Processing surface is not allowed to have rust and affect the performance, life or appearance of the bump, scratch and other defects.

 (4) Rolling finishing surface, after rolling shall not have peeling phenomenon.

 (5) After the final process of heat treatment of the parts, the surface should not have oxide skin. After the finishing process of the mating surface, tooth surface should not be annealed

(6) The machined thread surface should not have defects such as black skin, bumps, messy buckles and burrs.
