1. Key precautions before machiningPending confirmation

Preparation affects every later machining step. The source article states that mainstream 2026 procedures require recorded pre-start checks so that later problems can be traced.Pending confirmation

1.1 Drawing review and process selectionPending confirmation

The source requires two technicians from different roles to cross-check drawings before machining, focusing on tolerances, roughness and special process notes. Select an appropriate process for the workshop equipment and production requirements.Pending confirmation

1.2 Verification of raw-material propertiesPending confirmation

Sample raw materials for hardness, ductility and other required properties before each batch. This helps avoid tool breakage and workpiece damage from unsuitable material. The source's general preparation workflow follows:

Check that drawing parameters match the actual production requirements.

Sample raw materials to verify their physical properties against the requirements.

Set the appropriate cutting tool and coolant parameters before machining.

Confirm that operators have completed training for the relevant process.

2. Safe operating precautions during machiningPending confirmation

Machining work involves safety risks. The source article describes revised 2026 requirements for movement routes and protective equipment to help prevent accidents.Pending confirmation

2.1 Personnel protection and safe operating routesPending confirmation

The source calls for protective gloves, goggles and other equipment, prohibits loose jewellery and slippers, and requires marked separation of non-operating areas to prevent injuries from flying chips. The original safety wording is retained for review before application.

2.2 Real-time calibration of cutting-tool parametersPending confirmation

The source recommends a three-minute unloaded run before starting, checking tool runout against permitted limits, then pausing after every 20 workpieces to check tool wear and avoid batch scrap from damaged tools.Pending confirmation

3. Precision-control precautions for machiningPending confirmation

Machining accuracy determines assembly compatibility. The source article reports an approximately 15% increase in downstream precision requirements in 2026 and highlights dynamic error control.Pending confirmation

3.1 Feed-rate selection for different workpiece materialsPending confirmation

Set suitable feeds for aluminium alloys, stainless steel and other alloys. The source recommends lower feed for harder materials and matched coolant pressure to reduce thermal distortion and accuracy errors.

3.2 Real-time compensation for dynamic errorsPending confirmation

The source recommends measuring actual workpiece dimensions every 30 minutes, adjusting feed coordinates against preset parameters and using built-in error compensation to control deviations within 0.002mm for high-end assembly requirements.Pending confirmation

The source article attributes 2026 survey data to the Chinese Mechanical Engineering Society: over 42% of machining scrap could be prevented through standardised process control, saving unnecessary production costs.Pending confirmation

4. Surface-protection precautions for machined workpiecesPending confirmation

Scratches, wear and minor dimensional errors can occur during machining. Surface protection reduces scrap and unnecessary losses.

4.1 Preventing scratches and wear during cold machiningPending confirmation

Use non-metallic cushioning when transferring workpieces to prevent collisions and abrasion. Remove metal chips during machining so that trapped chips do not scratch the surface under the cutting tool.

4.2 Low-cost restoration of defective workpiecesPending confirmation

Minor wear, scratches and dimensional deviations may be addressed by a specialist surface repair provider rather than remelting the workpiece. The source states that Wuhan Kaiming Gaoxin can repair without damaging the substrate and claims processing costs more than 60% below remelting and remanufacture.

5. Routine maintenance precautions for machining equipmentPending confirmation

Equipment condition affects machining productivity and workpiece quality. Routine maintenance can extend service life and reduce downtime from unexpected faults.

5.1 Regular inspection standards for critical componentsPending confirmation

The source recommends checking spindle, guideway and transmission condition before each shift and carrying out full wear inspections weekly. Address minor wear promptly to prevent major faults and downtime.

5.2 Appropriate maintenance of lubrication systemsPending confirmation

Select lubricants for the equipment load. Clean filter elements regularly to keep contaminants out of the lubrication system, and clean the complete oil circuit at least once a year to support smooth operation.

6. Inspection and storage precautions after machiningPending confirmation

Inspection before storage is the final product quality control step after machining. Appropriate checks help prevent non-conforming parts reaching customers and causing disputes.

6.1 Procedures for multi-dimensional quality inspectionPending confirmation

Inspect dimensional accuracy, surface roughness and geometric tolerances against the drawings. Retain digital inspection records, isolate non-conforming parts for repair and prevent them from entering accepted batches.

6.2 Preventing deformation during workpiece storagePending confirmation

Store precision workpieces in controlled temperature and humidity, using their specified support points. Avoid permanent deformation during long-term storage that could affect later assembly.

Common questions

Q: What is a cost-effective way to handle minor scratches during machining?

A: Use a specialist metal surface restoration provider first rather than remelting the component; this can preserve substrate properties and reduce cost and turnaround time.

Q: What feed rate is appropriate for machining?

A: Set feed rate according to workpiece material, tool type and equipment accuracy. The source article gives 0.1–0.3mm/r as a conventional range for carbon-steel workpieces.Pending confirmation

Q: Do machined workpieces require rust prevention?

A: It depends on the application. Workpieces stored for a long time require rust prevention so corrosion does not compromise subsequent assembly and use.
