Our Custom CNC Machining Service & Processes

We perform custom CNC machining operations according to parts geometry, material, tolerance, and drawings requirements. CNC turning, milling, boring, reaming, tapping, internal threading, external threading, chamfering, grooving, and parting according to parts requirements and drawing.

CNC Turning

We perform CNC turning for round and cylindrical turned components. CNC turning typically 5 mm to 180 mm outer diameter. Common CNC turning parts we make include shafts, bushings, sleeves, spacers, flanges, hose nipple, adapters, and similar CNC turned parts

CNC Milling

CNC milling is used to machine flat surfaces, slots, pockets, holes, and profiles. Most milling work is performed using 3-axis and 4-axis machining for prismatic parts. 4-axis: indexed multi-face components. CNC milling parts such as milled brackets, blocks, plates, etc.

5-Axis Positioning & Secondary Operations

Parts that require both turning and milling are processed in multiple steps. Turning is usually completed first, followed by milling operations in a separate setup.

4-axis machining is mainly used for indexed operations where parts are rotated and machined in steps. 5-axis machining is supported for positioning and multi-face access, not for complex simultaneous contour machining.

Typical machining tolerance for standard CNC parts is ±0.1 mm, depending on material and feature geometry.

Post machining operations are used where required after CNC machining.

Post-Machining Operations

• Deburring
• Surface Finishes (Bead Blasting, Polishing, anodizing, plating, powder coating, etc)
• Heat Treatment
• Laser Marking
• Cleaning
• Assembly

Materials Supported for CNC Machining

Materials are selected strictly as per customer drawing and specification. As an OEM component manufacturer, we machine industrial grades used in regular production.

Aluminum Alloys (6061, 6063)

Aluminum 6061 is used for general aluminum CNC machined components. 6063 is typically used for extruded profiles and non-load bearing parts. Common CNC aluminium parts include blocks, spacers, plates, and lightweight structural parts.

Stainless Steel (SS304, SS316, SS202)

We machine stainless steel grades including SS 304, SS 316, and SS 202. These grades are commonly used in CNC Stainless steel parts such as shafts, sleeves, fittings, couplings, and corrosion-resistant components.

Mild and Carbon Steel (EN8, EN1A, C45, IS 2062)

Mild and carbon steel grades such as EN8, EN1A, C45, and IS 2062 are commonly machined. Typical CNC steel parts include shafts, pins, spacers, support blocks, and general industrial components.

Brass and Copper Alloys (C36000, C26000, C11000)

Grades such as C36000, C26000, and C46400 are machined for brass turned parts and milled parts. Common CNC brass parts such as fittings, brass flanges terminals, connectors, and inserts.

Copper grades such as C11000 are machined for electrical and industrial components. Common CNC copper parts include terminals, connectors, contact parts, and solid copper blocks.

Bronze (PB1, SAE 660)

Bronze grades such as PB1 and SAE 660 are machined for selected applications. Typical CNC bronze parts include bushings, wear components, and bearing-related parts.

Plastics

Plastics are not CNC machined as standalone parts. Accessories such as O-rings, seals, washers, and gaskets are supplied through partners when required with metal components.

Raw material is sourced from approved external suppliers based on customer specifications and drawings.

Typical CNC Machined Parts We Produce

We manufacture CNC machined parts that are used as functional components in larger assemblies. These parts are custom-made and supplied for OEM production programs. All CNC machining parts are supplied with required finishing as per customer specification.

Common CNC machined parts include shafts, bushings, sleeves, spacers, and milled blocks. These components are typically used for alignment, support, rotation, or load handling in mechanical and electrical assemblies.

Electrical components such as neutral bars and terminals are produced from solid metal bars. Operations mainly include cutting, drilling, and threading based on customer drawings.

Parts are supplied as prototype samples, batch production, and repeat OEM components depending on project requirements. We do not supply standard catalog items.

Tooling and machining fixtures developed for CNC parts are dedicated to the customer and are not reused for unrelated projects.

CNC Machining Size and Capacity

We machine small to medium-sized CNC components based on part geometry, material, and machining requirements.

For CNC turning, CNC turned parts with outer diameters ranging from 5 mm up to 180 mm are supported. Turning length and feature complexity depend on part design and material.

CNC milling is used for compact to medium-sized CNC milled parts used in general industrial and OEM applications.

Machining capacity is reviewed on a case-by-case basis based on customer drawings and material specifications.

Machining is done to general industrial tolerances. Typical tolerance is ±0.1 mm unless otherwise specified on the drawing. Final tolerance capability depends on part design, material, and feature type.

Surface Finish and Post-Processing

All surface finishing and post-processing are carried out through qualified partner facilities. Parts are normally supplied with a finished and cleaned surface condition as specified by the customer.

CNC Aluminum parts are commonly anodized. Brass parts typically receive chemical cleaning to remove surface oxidation. Steel parts undergo mandatory washing and cleaning before dispatch.

Additional finishes such as powder coating, bead blasting, brushing, polishing, and plating are supported based on customer specifications. Finish type is selected according to part function and application.

Deburring and chamfering of machined edges are mandatory for all CNC machined parts. Laser marking for part identification is supported as a post-processing option.

CNC Parts Bulk Manufacturing, MOQ & Lead Times

We are a CNC parts bulk manufacturer and offer competitive prices for high-volume orders. Prototype parts are supported before full production. Typical sample quantity ranges from 1 to 10 pieces for testing and approval.

Small batch production is supported when it is part of a defined development and validation stage. Standalone low-volume production orders in the range of 10 to 50 pieces are generally not supported.

Our focus is on medium-volume and repeat CNC production for OEM customers. Blanket orders and scheduled repeat supplies are preferred.

High-volume CNC production is supported for repeat parts with stable designs and regular order schedules. Production volume is reviewed on a case-by-case basis based on drawings, material, and order frequency.

Lead time for sample development is approximately 10–15 days, but it depends on part geometry and complexity. For bulk orders, it is approximately 25–30 days, but it also depends on production volume and part geometry.

Inspection and Measurement Capability

Inspection is carried out at multiple stages to ensure parts meet drawing requirements. Dimensional checks are performed using vernier and digital calipers, height gauges, Go/No-Go gauges, and thread gauges.

Material verification is supported through material test reports and mill heat certificates provided by the raw material supplier, when required.

Basic dimensional inspection reports are provided on request. Profile inspection and CMM measurement are supported through qualified partner facilities when specified by the customer.

Inspection methods and reporting levels are defined based on drawing requirements and order scope.
