Precision Machining Process Steps
Precision machining has many steps. Each step helps make parts very exact. KEMING uses a special way that mixes investment casting and cnc machining. This lets them make hard shapes with smooth surfaces. The parts also work well and last long.
Design & Engineering
The first step is design and engineering. Engineers use CAD software to draw 2D and 3D models. These models show all the details and sizes. CAM software changes these designs into machine instructions. The team thinks about many things at this time:
They pick the material, like aluminum or stainless steel, for the part’s job.
They check what tolerance and surface finish the part needs.
They make sure the part is easy to make and strong.
They plan extra steps, like deburring or coating.
They choose a good partner to make the part right.
Software Type | Description |
|---|---|
CAD | Makes detailed drawings and models. |
CAM | Turns designs into machine steps. |
PDM | Keeps track of product data and work. |
ERP | Helps business steps work better. |
Engineers set rules for precision machining now. These rules help the rest of the process stay exact.
Sélection des matériaux
Picking the right material is important. The team looks at how strong, tough, and costly it is. They also see if the material is good for the environment. They check if the material can be cut well and if it fits the tolerance. Some common materials are titanium, aluminum, Inconel, stainless steel, and special alloy steels. These are used for planes, medical tools, and cars.
Matériau | Application |
|---|---|
Inconel® | Used for strong, important parts |
Acier inoxydable | Used in many different parts |
Titanium 6Al-4V | Light and strong for planes |
Alloy steels 9310, 8620, 6150 | Used for strong parts |
Cronidur® | Used for high-performance jobs |
The way they machine the part depends on the material. The right material helps get the right shape and smoothness.
Investment Casting Foundation
Investment casting makes the main shape of the part. First, they make wax patterns. These are covered with ceramic to make a shell. The shell is baked, and the wax melts out. Hot metal is poured in to make the part. The shell is broken off, and the part is cleaned.
Investment casting uses careful patterns and control. This makes smooth surfaces and tight tolerances, sometimes as close as ±0.005 inches.
Méthode | Tolerance Range |
|---|---|
Moulage à la cire perdue | ±0.005 inches |
Sand Mold Casting | Not as exact |
Precision machining often starts after investment casting. This step lets them make hard shapes and get ready for more work.
CNC Machining & Finishing
After casting, cnc machining makes the part better. Machines like mills, lathes, and grinders take away extra material. CNC turning shapes round parts. Drilling makes holes. Grinding makes surfaces smooth. Electrical discharge machining shapes small details.
Technique | Description |
|---|---|
Turning | Cuts material from a spinning part. |
Drilling | Makes holes in the part. |
Grinding | Makes the surface smooth. |
Usinage par décharge électrique | Shapes metal with electric sparks. |
Sawing | Cuts rough shapes from material. |
Finition | Polishes and gets parts ready to use. |
Surface finish can be different. Smooth machining gets 1.6 Ra μm roughness. Brushing and electropolishing can get 0.8 Ra μm. These steps make sure parts look nice and fit with other pieces.
Precision machining rules guide each step. The team picks the best way for each part.
Inspection & Quality Control
Checking and quality control are the last steps. The team checks every part to meet strict rules. They use sensors to watch temperature and humidity. Tools measure the part’s shape and size. Visual tools find small problems. Other tools check what the metal is made of. Fit testing tools make sure parts go together. Non-destructive tests like ultrasonic and X-ray find hidden problems.
Méthode d'inspection | Description |
|---|---|
Temperature and Humidity Sensors | Watch the air for good quality. |
Geometric Dimensioning and Tolerancing | Measure shapes and sizes. |
Visual Inspection Tools | Find surface problems. |
Material Analysis Equipment | Check what the material is made of. |
Assembly and Fit Testing Tools | Make sure parts fit and work. |
Méthodes de contrôle non destructif | Find inside problems safely. |
Precision machining needs these checks to stay exact and good. Tolerance can be as close as ±0.005 inches. Some jobs need even tighter limits.
Every step in KEMING’s process, from design to checking, helps make parts that are very exact and have hard shapes. Using both investment casting and cnc machining makes sure every part is accurate, smooth, and works well.
Technologies & Materials in Precision Machining
CNC Milling & Turning
KEMING uses advanced cnc machines to make parts very exact. CNC milling and turning are two main ways to shape metal. CNC milling uses spinning tools to cut metal into shapes. It is good for parts with many sides and details. CNC turning spins the part and cuts it to make round shapes. This way works well for making shafts, bushings, and threaded parts.
Fonctionnalité | Fraisage CNC | Tournage CNC |
|---|---|---|
Application | Complex shapes and details | Cylindrical parts and smooth finishes |
Précision | High accuracy on many surfaces | High precision for round features |
Efficacité | Versatile for many part types | Fast for custom cylindrical parts |
KEMING’s cnc machines can do 5-axis milling and multi-axis turning. These machines make parts with tight tolerances, as close as ±0.0002 inches. They help make parts for cars, planes, and medical devices.
Grinding, Drilling & EDM
Grinding, drilling, and EDM are also important for making parts. Grinding makes surfaces very smooth and removes tiny bits of metal. Drilling makes holes in the right places. EDM uses electric sparks to cut metal without touching it. This way can make very detailed shapes and sharp corners. EDM can reach tolerances as tight as ±0.0001 inches. It works well for hard metals and tricky designs.
EDM gives a nice surface finish and can cut thick parts up to 20 inches. It helps make parts with thin walls and small inside corners.
These methods help KEMING keep every part exact and lower mistakes.
Matériaux utilisés
Precision machining works with many metals and alloys. KEMING uses aluminum, stainless steel, titanium, and high nickel alloys. Aluminum is easy to shape and does not cost much. Stainless steel and titanium are strong and do not rust. High nickel alloys like Inconel and Monel are good for tough jobs. Other materials are tool steels, brass, copper, bronze, and beryllium copper.
Common materials for precision machining:
Alliages d'aluminium
Stainless steel (304, 316, 17-4 PH)
Titanium (Grades 1 and 4)
High nickel alloys (Inconel, Monel, Hastelloy)
Tool steels (D2, H12)
Brass, copper, bronze, beryllium copper
KEMING’s cnc machines let them pick the best material for each job. This helps make parts that are strong, light, and very exact.
