CNC Machining GGG40 Nodular Cast Iron Project

CNC Machining GGG40 Nodular Cast Iron Project

Ductile iron is a kind of high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is precisely based on its excellent performance that it has been successfully used to cast some parts with complex stress and high requirements for strength, toughness and wear resistance. GGG40 is a ductile iron grade of Germany standard, which is equal to QT400, ASTM A536 60-40-18, 60-40-15, FCD400, GS400-12, FGS400-12, 400/17, 420/12, 400-12, 400-18 and SG38, SG40.

Recently, we had completed a new case for CNC Machining GGG40 Nodular Cast Iron Project, let’s share this case study together here.

Project details:

Project Name: CNC Machining GGG40 Nodular Cast Iron Project Material: GGG40 Nodular Cast Iron

Process: CNC Machining, Milling, Threading and Deburring

Lead Time: about 45 days

Quantity: 300pcs

Product Application: this GGG40 nodular cast iron part will be used for supporting, which requires high precision.

1. Material Inspection

The raw material GGG40 produced by opening mold firstly, then they will be checked thoroughly by quality inspection team before production to make sure good quality.

2. Programme and Debug Machine

The machinist was inputting the code to make the programme and debug the cnc 4 axis cnc machining center before starting the machining process.

3. CNC Machining Milling with threading Process

(1) After debugging the 4 axis cnc machine, the parts will be start for machining production, different side and hole position need to be machined well, by using 4 axis cnc machine, which can achieve high efficient and high precision for parts for machining milling process. Also, the threading with holes will be finished during this process.

(2) After preliminary machining on the 4 axis cnc machine, then the parts will be further machined on the 5 axis cnc machine subsequently to achieve high precision and efficient by 5 axis combination for production.

4. Grinding Process

The parts will be ground for some areas to meet the surface roughness requirement on the drawing, which will make the surface of parts more smooth and nice.

5. Deburring Process

After the parts are machined well, it will be cleaned well and start to proceed with the deburring process to remove all burrs on the edges and corners for parts.

6. Quality Inspection Process

After completing a series of work-stage with cnc machining, cnc milling, chamfering and deburring, the finished product will be checked thoroughly by quality inspection team to make sure good quality work before shipment.
