Custom Service

How to custom your own sapphire parts:

service

Confirm specifications with DWG.

Before ordering, we need your DWG. to confirm important specifications and offer you the price and delivery information, generally the price will effected by the following items: 1. Dimensions; 2.Surface Flatness; 3.Surface Quality; 4.Quantity. Etc..

Ordering and Deposit Payment

After confirmed price and delivery time, please send us your purchase order and then we will send Proforma Invoice to you with our bank information and other important details. After we received the deposit payment we will start processing.

Packing And Delivery

When the goods are checked, we will pack them well and deliver by DHL to worldwide.

Components are wrapped in capacitor paper, each product is individually packaged in a

ziplock bag, then packaged in a sturdy PP box, and then put PP box in carton box. 

Typical sapphire processing steps in our factory are as follows:

Typical sapphire processing steps in our factory are as follows

X-Ray NDT Crystal orientation apparatus

First, we use crystal orientation instrument to detect crystal orientation,and then we will mark the orientation as customer’s requests

Sapphire Brick Cutting

Then we will slice the sapphire brick, the thickness is close to the finished product, but reserve the removal layer thickness required for grinding and polishing

Rounding Machines

If the final product is round shape, then we will round the cut square or round flat sheet to bring the roundness of the product to the required level

Rounding Machines

Grinding Room

After finishing all the previous work on the shape, we will processing the surface of the product from grindingDepending on the degree of demand for machining accuracy, we use two different processes, single-sided grinding or double-sided grinding.  

Grinding Room

Single-side grinding & polishing machine

Single-sided grinding takes longer and is suitable for products with high surface requirements

Single-side grinding polishing machine

Double-sides grinding & polishing machine

Double-sided grinding processing is faster than single-side grinding, it can complete two surface grinding on the same time, and the product parallelism of double-sided grinding is better than that single-side grinding

Double-sides grinding polishing machine

Manual Chamfering

Chamfering can effectively avoid the bad effects of edge collapse on product grinding and polishing in the process of machiningIt also protects workers from cuts when transporting products.

Fine grinding process workpiece

After finishing the first grinding process, it will enter the second grinding, fine grinding process

Thickness Measuring

When the fine grinding process complete, we need to measure the thickness and make sure it is in the tolerance of finished product. Thickness will not change during polishing process, so the thickness after fine grinding should be within the requirements of the finished product.

Thickness Measuring

Polishing Room

If the surface quality of the fine grinding product can pass the inspection of our skilled workers, then it enters the final stage of processing, polishing. Same with grinding, we will use two different polishing methods depending on the customer's surface quality requirements.

Double Polishing Room And Ultrapure Water Equipment

Double-sided polishing can greatly reduce the time required for polishing, while eliminating the processing steps of the adhesive plate, so it is usually used in the surface quality requirements are not high, but the processing quantity is large

Single Side Polishing

For products with high surface quality requirements, it is often necessary to process one-sided on a single-sided polishing machine to reduce the variables that need to be controlled in the processing process, and high-precision surface types often need to be adjusted and processed repeatedly to obtain, which also determines why the price of high-precision products is much higher than the general precision of the product

Single Side Polishing

Dimensions Checking

After processing and cleaning, the product is sent to our quality inspection center for a series of tests to ensure that the finished product meets the customer's design requirements. Of course, the finished product testing here does not represent all our testing procedures and quality assurance means, Product testing will run through the entire processmainly as Dimensions, roundness, parallelism, verticality, angle, surface flatness.

Dimensions Checking

Surface Quality Checking

We use standard optical inspection lights and microscopes to check for scratches and spots on the surface of the product

Surface Quality Checking

Surface Flatness Checking

 

The surface flatness and parallelism of the product will detected by using the laser interferometer
