How does KGL ensure part quality?

KGL works with a wide range of metals, engineering plastics, and other non-metallic materials. This allows us to handle different types of custom parts, including precision components, equipment structures, housings, flanges, shafts, and parts with complex curved surfaces.

For metal parts, available materials include carbon structural steel, alloy structural steel, free-cutting steel, spring steel, bearing steel, carbon tool steel, alloy tool steel, and high-speed tool steel. Stainless steel options include martensitic, ferritic, precipitation-hardening, and austenitic grades. Iron, aluminum, copper, titanium, and other metals can also be machined according to project requirements.

KGL also processes general-purpose and high-performance engineering plastics, as well as rubber, insulating materials, and ceramics. Machining methods are selected according to the part and material, with turning, milling, grinding, 3-axis, 4-axis, 5-axis, and gantry machining available. Parts can be made from customer drawings, samples, or ODM requirements, whether the project involves a single custom part, a prototype, a small- or medium-volume order, or batch production.

KGL provides custom precision component machining services covering manufacturing requirements from drawing evaluation and prototype production to batch manufacturing. Core capabilities include 2.3-axis, 4-axis, and 5-axis CNC milling, CNC turning, mill-turn machining, drilling, tapping, and precision grinding. These processes can be used for complex curved surfaces, irregular structures, equipment components, housings and enclosures, fixtures, and prototypes.

In addition to CNC precision machining, KGL also provides rapid prototyping, mechanical part design, sub-assembly, wire EDM, EDM, laser cutting, Swiss-type machining, automatic turning, injection molding, die casting, investment casting, and sheet metal fabrication. Customers can select a single machining process or a multi-process manufacturing solution based on their project requirements.

For secondary processing, KGL provides anodizing, chemical conversion coating, sandblasting, black oxide, brushing, polishing, electroplating, electrophoresis, and painting services, covering the manufacturing and surface treatment needs of precision parts made from metals and engineering plastics.

KGL typically responds with quotation information within 24 hours of receiving a customer inquiry.

Customers can provide part drawings, material specifications, quantities, dimensions, tolerances, surface treatment requirements, and other relevant information. This allows KGL to prepare quotations for CNC machining, mill-turn machining, grinding, wire EDM, or other applicable processes. For custom parts involving complex structures, multiple materials, or a combination of several processes, quotation lead times may vary. If there is any delay, KGL will notify the customer promptly.

KGL provides precision machining services ranging from single-piece customization and prototype production to batch manufacturing, supporting different stages of the procurement process.

KGL can typically control CNC machining tolerances within ±0.003 mm to ±0.01 mm, depending on the part material, structure, and machining requirements. This is suitable for custom parts requiring dimensional accuracy, precise assembly relationships, and complex curved surfaces.

For critical features that directly affect assembly, sealing, or motion accuracy, additional precision machining can be arranged based on the part drawing, material, and process conditions. This supports different project requirements from sample validation to batch production.

KGL operates more than 100 imported CNC machines and is equipped with coordinate measuring machines (CMMs). With ISO 9001, ISO 13485, and AS9100D certifications, KGL provides CNC machining support for precision components used in medical, aerospace, robotics, and other industries.

KGL can machine custom precision parts up to 2,500×1,500×800 mm, covering the machining needs of large structural components, housings, enclosures, and other custom mechanical parts.

KGL operates more than 100 high-precision machines, including large gantry machines, 5-axis and 4-axis machining centers, vertical and horizontal CNC machines, dual-spindle mill-turn machines, CNC lathes, grinding machines, milling machines, and wire EDM equipment. KGL provides complete production support from rough machining to precision machining, serving single-piece prototypes, rapid prototyping, and batch production orders.

For customized solutions involving large or special requirements, please contact us.If you have a part close to or beyond the standard size, it is still worth sending us the drawing. We can check whether the component is practical to produce before suggesting a machining method.
