What Is The General Charging Standard For External Wire Cutting

[Arlinda Seegmiller]

generally, the charging standard for external wire cutting processing: wire cutting processing is generally calculated by area. General parts processed by wire cutting are charged according to the cutting area (mm2) * 0.008 yuan. For parts requiring threading, the price shall be increased by 5 yuan per threading hole
other related charges:

I. pricing method based on man hours:

z25 drilling machine, CA6140 lathe planer, slotting machine and sawing machine are charged at 15 yuan per hour

vertical and horizontal milling, wire cutting, large lathe and gantry milling are charged at 20 yuan per hour

fitters charge 15 yuan per hour for general maintenance

the timing unit starts from taking over the processing to the completion of processing and acceptance

II. Charging method according to the requirements of parts, quantity and accuracy:

the charging standard of general flange parts is charged according to the straight diameter of material * 0.07, and the diameter greater than 430mm is charged according to the diameter of material * 0.12

generally round nut parts are charged by diameter * 0.25 (including materials)

generally trapezoidal, triangular nut parts are charged by diameter * 0.3 (excluding materials)

generally shaft sleeve parts (diameter less than 100, diameter length ratio less than 2) are charged by material outer diameter * 0.2, and those with diameter length ratio more than 2 are charged by diameter length ratio * base price * 0.6

generally, the wear of bearing platform parts is less than 2mm, the diameter is less than 40mm, and the width is less than 25mm. Each 5 yuan needs to be put on the center frame, Or the base price of more than 1.7m * 2. If the diameter is greater than 40mm, it shall be charged according to diameter * 0.2

3. For general keyway processing of milling machine processing

(length width ratio less than 10), the keyway width * 0.5 will be charged (minimum 5 yuan). If the aspect ratio exceeds 10, it shall be charged according to the aspect ratio * base price * 0.1. If there are strict positional requirements, it shall be charged at the base price * 2. The processing of materials with hardness greater than hrc40 shall be charged at the base price * 2. For general spline machining (with length diameter ratio less than 5), the outer diameter of spline shaft * 0.8 (minimum 15 yuan) is charged. For general gear machining, the module * number of teeth * 0.5 yuan is charged. Worm gear is charged according to base * 1.2. Helical gear, bevel gear and deflection gear are charged at the base price * 2. General plane processing is charged at 1.5 yuan per square decimeter (minimum 5 yuan). General boring processing is charged at hole diameter * 0.25

4. Cut off the general round steel, thick wall pipe and square steel processed by band saw at 5 yuan per square decimeter (minimum 5 yuan). Cut off the general steel plate and divide it into strips. The opening angle is 10 yuan per square decimeter (minimum 10 yuan)

5. General parts processed by wire cutting are charged according to the cutting area (mm2) * 0.008 yuan. For parts requiring threading, the price shall be increased by 5 yuan per threading hole

6. For electric welding, gas cutting and plasma cutting, 1 yuan for each ordinary electrode with a diameter of 3.2 and 3 yuan for th506 welding castings. For gas cutting processing, plasma cutting stainless steel is calculated according to the iron plate thickness mm * cutting length m, which is charged according to the gas cutting base price * 3, and cutting carbon steel is charged according to the gas cutting base price * 2
7. For special urgent parts and overtime parts, the standard base price * 2 is charged. The definition of special urgent parts is: arrange to repair or manufacture emergency parts for a specific customer at the first time. Overtime parts refer to parts that must be manufactured continuously beyond normal working hours

the processing cost of optical tool curve grinding is 60 yuan /hour

200 lathes, 20 yuan /hour

lathes over 300, 30 yuan /hour

milling machines, 20 yuan /hour

drilling, 15 yuan /hour

boring machines, 35 yuan /hour

grinding machines, 30 yuan /hour

slotting machines, 15 yuan /hour

shapers, 20-25 yuan /hour

hobbing machines (steel plate thickness below 20) are 60 yuan /hour

C620 C6140 basic 20 yuan per hour

30 yuan per hour for lathe

50 yuan per hour for vertical lathe

20 yuan per hour for 400 square meters and less than one meter for outer circular lathe

60 yuan per hour for three meters

80 yuan per hour for machining center (counting milling and counting cars)

Electric welding and gas cutting are basically calculated by pieces, and those inconvenient to As precision milling operation calculate are calculated by 30 yuan per hour

fitter assembly is 20 yuan per hour

in addition, the labor payment is also related to the quantity of outsourced processing

price = material cost + production cost (design cost, various processing costs, utilities, machine depreciation, labor cost...)+ Tax

hardware cost accounting standard (for reference only)

unit price = material fee + [processing fee * (1 + tax 17%)] * [1 + loss fee (4%) + management and sales fee (5%) + profit (10%)]

I. Calculation of material cost:

total material weight * material price - (total material weight - net product weight) * waste recycling price

external processing man hour price of various machine tools

in fact, the man hour price of various types of work is not fixed. It will vary according to the difficulty of workpieces, the size of equipment and performance. Of course, the key depends on your quantity, but generally speaking, it has a basic price, which fluctuates between the basic prices

1. The basic price of the car: 20-40

the specific price depends on the actual situation. For example, for small parts, the simple working hours are less than 20 yuan; Sometimes it's even only 10 yuan. For example, for some large pulleys, the machining allowance is large, and the boss only earns the money of cast iron powder; Sometimes, if the workpiece is large, it can be higher if it can't be processed on the market. Two or three times, others can't help it

2. Basic grinding price: 25-45

3 Milling basic price: 25-45

4 Basic price of drilling: 15-35

5 Basic price: 15-35

6 Basic price of wire cutting: 3-4/900 mm2

7 Basic price of electric spark: 10-40, generally 50 per piece (less than 1 hour)

8 NC basic price: 2-4 times more expensive than ordinary ones

9 Engraving: usually single piece. 50-500 /piece
