Pricing Method for Machining of Mechanical Parts

Pricing calculation for machining is an indispensable step in outsourced processing. The accuracy of machining price calculation directly affects the processing, production, and sales of products, making it a top priority.

What Aspects are Included in the Price

Material costs: the cost of purchasing materials, transportation costs of materials, and travel expenses incurred during procurement, etc.

Machining costs: labor costs in each process, depreciation of equipment, utility costs, cutting tools, fixtures, measuring tools, and other consumable costs.

Management fees: amortization of fixed costs, salary distribution for management personnel, site costs, kickbacks, travel, etc.

Taxes: national taxes, local taxes, etc.

Profit

Simple Pricing Calculation Method

Based on the product's material cost for a simple estimation. (Divided by the complexity of processing)

Simple: Material cost 50%, machining cost 30%, management fee 5%, tax 17%, and your profit 8%. High value-added: Material cost 10%, machining cost 40%, management fee 5%, tax 17%, and your profit 28%.

High-tech: Material cost 10%, machining cost 20%, management fee 10%, tax 17%, and your profit 43%.

Pricing Calculation Method

Calculate the machining costs based on the quantity, size, precision requirements, etc. of the parts; Drilling

For a depth-to-diameter ratio not greater than 2.5 times, with a diameter of 25MM or less, charge according to the drill bit diameter * 0.05;

For diameters between 25-60, charge according to the drill bit diameter * 0.12 (minimum hole charge is not less than 0.5 yuan).

For a depth-to-diameter ratio greater than 2.5, the general material charging base price is 0.4 times the depth-to-diameter ratio.

For hole diameter precision requirements less than 0.1MM or center distance requirements less than 0.1MM, charge at the base price * 5.

Tapping charges are based on a tap diameter * 0.2 (with cast iron as the standard, and steel parts are 1.2 times).

During batch processing, the standard base price is multiplied by 0.2-0.8 (depending on the size of the batch and the complexity of the processing).
