How to quote cnc machining

Oct 16, 2019

When outsourcing processing, quotation is a very critical step, especially for CNC processing, quotation is the most important.In CNC machining, the price is a certain calculation formula.These formulas can be very good to help you calculate a reasonable CNC machining price.CNC machining center is mainly for a number of types of small and medium-sized batch parts.With the cost of CNC machining center machining manufacturing gradually decreased, there are processing a large number of parts.



It is also possible to shorten program debugging time and tooling preparation time when processing small batches and single parts.CNC machining center machining surface roughness value of small parts.The surface roughness depends on the cutting speed and feed speed when the material, finishing allowance and tool Angle of the workpiece and tool are certain.


I. product cost


Analysis in the CNC machining quotation, the first need to make a general analysis of the cost of the product.Provide more accurate data basis for quotation.


1. Inquiry process: receive business, purchase new products -- inquiry -- understand the content, confirm the demand -- seek suppliers -- check the quotation before similar products -- manufacturer's quotation -- confirm the unit price and submit it to the supervisor for approval -- reply to relevant units -- track and confirm the unit price and other information -- feedback and report.


2. Evaluation process: read the business evaluation -- content analysis -- fill in the evaluation details -- supervisor approval -- send the original to the business department -- track the quotation and confirm -- the business will confirm the original quotation details into the computer -- confirm the cost of each process.


Two, CNC machining machine planning standards


The first calculation standard (when the program simulation time is less than or equal to 120 minutes), the planned time =[calculation time for clamping and measurement + thermal engine time + (program simulation time *1.7 times)]* number of pieces


The second calculation standard (when the program simulation time is greater than 120 minutes), the planned time =[calculation time for clamping and measuring + thermal engine time + (program simulation time *1.5 times)]* the number of pieces.
