Surface Grinding Service

(Common Grades: A2, D2, O1, M2, S7, H13, CPM series) are known for their high hardness, wear resistance, and ability to hold a sharp edge. They are frequently ground after heat treatment to achieve final dimensions and required tolerances.

Good for:

• Dies and punches
• Mold components (cores, cavities, inserts)
• Cutting tools (blades, shear knives)
• Wear-resistant components
• Precision gauges and fixtures

Why customers choose it: “Surface grinding allows us to achieve the critical flatness, parallelism, and fine surface finish required on hardened tool steel components, ensuring optimal performance and tool life.”

(Common Grades: 303, 304, 316, 410, 420, 440C, 17-4 PH) offer excellent corrosion resistance combined with good strength. Different grades have varying levels of hardness and grindability. Often ground for precision applications in demanding environments.

Good for:

• Medical device components
• Food processing equipment parts
• Precision shafts and rods
• Corrosion-resistant fixtures and tooling
• Mold components requiring corrosion resistance

Why customers choose it: “Grinding provides exceptionally smooth, precise, and corrosion-resistant surfaces on stainless steel parts, vital for hygiene, performance, and longevity in challenging conditions.”

(Common Grades: 1018, 1045, 4140, 4340, 8620) are versatile ferrous materials offering a range of strengths and hardness levels (often enhanced by heat treatment). Surface grinding is used extensively for flatness and finish.

Good for:

• Machine components (base plates, brackets)
• Precision shims and spacers
• Fixtures and jigs
• Shafts and spindles
• Gears (pre- or post-heat treat finishing)

Why customers choose it: “It’s a cost-effective method to achieve tight tolerances on flatness, parallelism, and specific surface finishes for a wide variety of common mechanical and structural parts.”

(Common Types: Gray Iron, Ductile Iron) offers excellent vibration damping, good machinability (though abrasive), and wear resistance. Typically ground to create flat, stable mating or sliding surfaces.

Good for:

• Machine bases, tables, and ways
• Engine blocks and cylinder heads (deck surfaces)
• Manifold sealing surfaces
• Surface plates
• Brake rotors and drums

Why customers choose it: “Grinding creates the extremely flat, stable, and wear-resistant surfaces necessary for machine tool accuracy, effective sealing, and reliable performance in cast iron components.”

(Common Grades: 6061, 7075, 2024, Cast grades, MIC-6) is lightweight, corrosion-resistant, with high thermal and electrical conductivity. Grinding aluminum requires specific techniques (specialized wheels, coolants) to prevent wheel loading but can achieve excellent finishes.

Good for:

• Precision fixtures where weight is a concern
• Electronic chassis and enclosures requiring flat mating surfaces
• Heat sinks needing specific flatness for thermal contact
• Optical components
• Mold components (where high finish is critical)

Why customers choose it: “While challenging, grinding aluminum provides superior flatness and surface finish compared to other methods when these characteristics are critical for the application.”

(Common Grades: Grade 2, Grade 5 / Ti-6Al-4V) is known for its high strength-to-weight ratio, excellent corrosion resistance, and biocompatibility. Grinding is challenging due to its reactivity and heat generation but necessary for precision applications.

Good for:

• Aerospace structural components
• Medical implants (e.g., joint replacements)
• High-performance automotive parts
• Marine hardware
• Chemical processing equipment components

Why customers choose it: “For critical titanium parts in aerospace and medical fields, grinding is essential to meet stringent requirements for tolerance, surface integrity, and finish.”

(Examples: Inconel, Hastelloy, Monel, Waspaloy) are nickel-, cobalt-, or iron-based alloys designed for extreme environments (high temperature, high stress, corrosive). They are very difficult to machine and grind, requiring specialized expertise.

Good for:

• Gas turbine engine components (blades, vanes, discs)
• Aerospace combustion and exhaust sections
• Chemical and petrochemical processing equipment
• Nuclear applications
• High-temperature tooling

Why customers choose it: “Grinding is often the only feasible method to achieve the necessary dimensional accuracy and surface integrity on complex superalloy parts destined for the most demanding applications.”
