How Do CNC Precision Machining Manufacturers Quote? How To Calculate Costs?

The Material Cost Is Certain, The Main Difference Lies In The Different Labor Costs, Transportation Costs, Consumption Costs Taxes Of Each Company. So How Do Most Machining Factories Calculate These Costs?

The Following Is Some Information Compiled By Huiwen Zhizao Editor For Reference (Because The Calculation Method Varies Due To Local Prices)

Detailed Calculation Method For Precision Machining Manufacturers

1) First, You Can Ask The Other Party To Provide Preliminary Process Arrangements For Key Complex Parts, Including Details Of Each Process The Time Required For Each Process.

2) The Processing Cost Can Be Calculated Based On The Hourly Cost Of The Equipment Required For Each Process. You Can Also Ask The Supplier For The Specific Equipment Cost, For Example: Ordinary Vertical Milling Machine Is Between ￥60~80 Per Hour (Tax Included); Ordinary Equipment Such As Milling Machines General Lathes Are Generally ￥30.

3) Add Packaging Transportation, Management Costs, Tooling Profit In Proportion To Get The Price. Of Course, The Price Will Be Closely Related To The Annual Purchase Volume Difficulty Of The Part. It Is Easy To Understand That There Will Be A Big Difference In Price Between Single Piece Batch. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience . It Has Complete Equipment, CNC Lathe/Milling/Grinding/Drilling/Machining. Welcome Partners With Parts Processing Needs To Call Us For Quotation.

Rough Estimation Method For Machining :

1) For Large Items, The Volume Is Larger The Weight Is Heavier.

Moderate Difficulty: The Ratio Of Processing Cost To The Raw Material Cost Of The Entire Part Is About 1:1, This Ratio Is Inversely Proportional To The Purchase Volume;

More Difficult: The Ratio Of Processing Cost To The Raw Material Cost Of The Entire Part Is About 1.2~1.5:1, This Ratio Is Inversely Proportional To The Purchase Volume;

2) For Small Medium-Sized Items

Moderate Difficulty: The Ratio Of Processing Cost To The Raw Material Cost Of The Entire Part Is About 2~3:1, This Ratio Is Inversely Proportional To The Purchase Volume;

More Difficult: The Ratio Of Processing Cost To The Raw Material Cost Of The Entire Part Is About 5~10:1, This Ratio Is Inversely Proportional To The Purchase Volume;

Since Machining Has Great Process Flexibility, That Is, A Part Can Have Many Process Arrangements, The Costs Are Of Course Different. However, Suppliers Sometimes Give You A Complex Process To Increase The Price When Quoting You, While Other Simpler Processes Are Used In Actual Production. Therefore, The Buyer's Own Reading Of The Drawings Knowledge Of Parts Processing Determine Your Grasp Of Costs. Therefore, The Purchase Of Mechanical Parts Requires Relatively Comprehensive Knowledge Of Machining.

The Composition Of Machining Costs Is Generally Based On Working Hours!

If You Want To Process A Workpiece, The First Thing You Have To Pay Is The Material Cost Of The Other Party; Then There Is Some Travel Expenses For Purchasing The Workpiece (Usually There Is None);

The Most Important Thing Is The Processing Time Required For The Workpiece You Want To Process. Generally, Lathe Workers Pay 10-20 Yuan Per Hour, Fitters Pay Less, About 10-15 Yuan Per Hour. The Rest Are Listed Here.

If There Are No Ready-Made Tools (Such As Knives, Molds), You Will Need To Bear Part All Of The Purchase Cost; The Final Total Is The Processing Fee You Have To Pay!

The Basics Include Material Costs, Machine Depreciation, Labor Costs, Management Fees, Taxes, Etc. Material Costs, Processing Fees Taxes, As Well As Business Expenses Transportation Costs. To Make A Budget, You Need To Have A Thorough Understanding Of The Market. If You Don't Work In It For A Few Years, You Will Have No Idea At All. Even My Teacher Often Sighs! You Can't Be Careless At All! Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Processing Experience. It Has A Full Range Of Equipment, CNC Lathe/Milling/Grinding/Drilling/Processing. Welcome Partners With Parts Processing Needs To Call Us For Quotation.

The Process Should Include Material Costs, Processing Costs (The Price Will Be Different Depending On The Type Of Processing), Equipment Depreciation, Worker Wages, Management Fees, Taxes, Etc. The Main Thing Is To First Determine The Process, That Is, The Processing Method, Then Calculate The Working Hours Based On The Process. The Basic Processing Cost Of A Single Part Is Determined By The Working Hours, Then Other Costs Are Added. The Process Is A Very Complicated Subject. A Part Uses Different Processes The Price Is Different.

In Fact, There Is No Fixed Price For Each Type Of Work. It Will Vary According To The Difficulty Of The Workpiece, The Size Of The Equipment, The Performance. Of Course, The Key Is To See How Much You Do. But Generally Speaking, There Is A Basic Price, Which Fluctuates Between The Basic Prices:

1. Basic Price Of The Car: 20-40

The Specific Amount Depends On The Actual Situation. For Small Items, Simple Labor Hours May Be Less Than 20 Yuan; Sometimes Even Only 10 Yuan.

For Example, Some Large Pulleys Have Large Machining Allowances, So The Boss Only Needs To Make Money Cast Iron Powder;

Sometimes If The Workpiece Is Large Cannot Be Processed On The Market, The Size Can Be Higher, Two Three Times, Others Can’t Do Anything About It.

2. Grinding Basic Price: 25-45

3. Basic Price Of Milling: 25-45

4. Diamond Basic Price: 15-35

5. Basic Price: 15-35

6. Basic Price Of Wire Cutting: 3-4/900 Square Millimeters

7. Basic Price Of EDM: 10-40, Single Piece Is Generally 50/Piece (Less Than 1 Hour)

8. NC Basic Price: 2-4 Times More Expensive Than Ordinary Ones

9. Carving: Generally It Is Single Piece, 50-500/Piece. Of Course, The Price Depends On The Specific Product.

The Above Prices Are For Reference Only. If You Have Any Experience, I Hope You Can Share It We Can Communicate Together.
