I. Customized CNC machining process for non-standard parts:

(1) process: a worker or a group of workers, in a workplace or a machine tool to or together to several workpieces completed in succession that some of the technical process is called process.

(2) device: in the non-standard parts custom machining process, so that the workpiece in the machine tool or the fixture occupies an accurate position and is clamped process, known as clamping.

(3) station: the use of transposition (or shift) fixture, reversing the table or processing on multi-axis machine tools, the workpiece in the machine once after clamping, to be processed in sequence through several positions, the workpiece in the machine tool occupies each position completed in that some of the processes are called station.

(4) work step: in the processing of the appearance of the same, processing tool under the same conditions, the successful completion of some of the process content is called the work step.

(5) go knife: non-standard parts custom machining tool in the processing of the exterior of the finished work step once some called go knife.Blackening using equipment: acid-resistant tank six filter pump using products: 1: 1-4 times water for dilution water washing, rinsing should be two cleanings, the workpiece in the cold water tank up and down shaking be sure to wash the residual liquid clean. Check the workpiece surface PH value is neutral (6 ~ 7).

1. Oil removal, rust removal is the most critical, as long as the pre-treatment is good, then the blackening is very simple.

2. The time of blackening treatment is usually 2 minutes, after taking it out, stay in the air for 1~2 minutes, and then wash with water. Blackening working solution PH value to maintain 2.

3. Strictly control the time of blackening, mastering the standard is the surface of the workpiece has a uniform layer of slightly gray black

The film can be moved, the blackening liquid should be light, not thick, blackening time should be short, not long.

Non-standard parts custom CNC machining principle:

Non-standard parts custom machining technology process. Blank production, parts processing, heat treatment, quality inspection, and machine assembly. Tooling, fixture production.

In the process of non-standard parts mechanical CNC machining, the basis is the most important, processing precision benchmark, and then changing the precision benchmark positioning production and processing of other surface layers.

1. For the box parts, the main hole is a rough reference for the production of the processing plane, and then the plane is a fine reference for the production of the processing hole system.

2. for shaft parts, generally the outer circle is a rough reference for machining the center hole, and then the center hole is a fine reference for the production of machining the outer circle, end face, and other surface layers.

Reasonable arrangement of non-standard parts custom machining production CNC processing sequence, first centralized and reasonable arrangement of each surface layer of rough machining, the middle according to the need for reasonable arrangements for semi-finish machining, and finally reasonable arrangements for finishing and finishing production processing. For the high precision requirements of the workpiece, to reduce the impact of roughing-induced deformation on the custom finishing of non-standard parts, usually roughing and finishing should not be completed continuously, but should be completed in stages, spacing moderate periods.

Packing: Inner is Poly foam, out is carton. Then pallet. Carton size: 29*19*19.5CM and 23.5*17.5*8, CM and pallet size is: 215*100*90CM, or as your requirement.

Packing for CNC Steel parts:

1. Usual packing: By pearl cotton/bubble bag/plastic wrap + carton box, 0.5-10kg/carton box.

2. Special packing(for large part/large quantity order): By pearl cotton/bubble bag/plastic wrap +carton box+wooden box.

3. As customers' requirement for CNC aluminum parts
