What is the formula for machining quotes in the machinery industry? How to calculate?

There is no uniform formula for the processing offer in the machinery industry, but according to the different circumstances of different machinery to be calculated separately. Specific ways are as follows:

1, the method of pricing to work hours:?

1, 15 yuan per hour: mainly including Z25 drilling machine, CA6140 lathe, planer, sawing machine, several processing methods, as well as most of the work of the clamping machine.

2, 20 yuan per hour: mainly including vertical milling machine, horizontal milling machine, wire cutting, large lathe and gantry milling machine and other processing methods.? Hourly unit from the beginning of acceptance of processing tasks to the completion of the entire project acceptance of the end.?

Two, according to the parts, quantity, accuracy of the requirements of the billing method:?

1, milling machine processing class of general keyway processing.

(1) aspect ratio is less than 10: according to the keyway width × 5 to calculate the minimum of 5 yuan.?

(2) Aspect ratio more than 10: charged according to the aspect ratio × base price × 0.1. If there are strict requirements for unknown × 2 to calculate. Hardness greater than HRC40 material processing is calculated according to the base price × 2.?

(3) Spline machining (L/J ratio less than 5): Charged according to the spline outer diameter × 0.8, minimum 15 yuan.

(4) general gear type processing: modulus × number of teeth × 0.5 yuan to charge.?

(5) general flat machining category charged at 1.5 yuan per square meter, the minimum of 5 yuan, general boring processing in accordance with the hole diameter × 0.25.

2, boring processing general materials.

(1) depth-diameter ratio of not more than 2.5 times the diameter of 25mm: diameter × 0.05.?

(2) diameter 25-60mm: drill diameter × 0.12, the smallest hole charges no less than 0.5 yuan.?

(3) General materials with depth-to-diameter ratio greater than 2.5 times the diameter: base price × depth-to-diameter ratio × 0.4 charged.?

(4) for the hole diameter accuracy requirements of less than 0.1mm or for the center distance requirements of less than 0.1mm: base price × 5 calculated.

3, lathe processing class general precision optical axis processing.?

(1) long Jing ratio is not greater than 10: workpiece blank size × 0.2 billing, the minimum 5 yuan.

(2) L/D ratio greater than 10: general optical shaft base price × L/D ratio × 0.15.?

(3) precision requirements within 0.05mm, or requirements with taper: optical shaft base price × 2 charged.?

(4) General step shaft (fan shaft, pump shaft, reducer shaft, grinding wheel shaft, motor shaft, spindle): base price × 2 charged.?

(5) Stepped shaft with taper, internal and external threads: base price × 3 charged.

4, band saw processing category.?

(1) general round steel, thick-walled pipe, square steel cut-off: 5 yuan per square meter, the lowest 5 yuan.?

(2) general steel plate cutting, slitting, cornering: no square meter 10 yuan, the lowest 10 yuan.
