Working Process

A process that combines lighter milling passes with high spindle speeds and high feed rates to achieve a very high metal-removal rate, high-speed machining helps reduce cycle time, increase tool life and increase shop productivity. Machinists use high-speed machining to make their work faster and easier. Faster productivity rates mean the machines can produce more parts in a short period. machining, also known as subtractive manufacturing, is a prototyping and manufacturing process that creates the desired shape by removing unwanted material from a larger piece of material. Machining is a part of the manufacture of many metal products, but it can also be used on other materials such as wood, plastic, ceramic, and composite material. Much of modern-day machining is carried out by computer numerical control (CNC), in which computers are used to control the movement and operation of the mills, lathes, and other cutting machines. This increases efficiency, as the CNC machine runs unmanned therefore reducing labour costs for machine shops.

Fabrication of metal is the creation of metal structures by cutting, bending, and assembling processes. In brief It is a value-added process involving the creation of machines, parts, and structures from various raw materials. Hence It usually starts with drawings with precise dimensions and specifications. Whereas shops are employed by contractors, OEMs and VARs. Typical projects include loose parts, structural frames for buildings and heavy equipment, and stairs and hand railings. In fact as with other manufacturing processes, both human labor and automation are commonly used. The end products of other common types of metalworking, such as machining, metal stamping, forging, and casting, may be similar in shape and function, but those processes are not classified as fabrication. Fabrication is the process of constructing products by combining typically standardized parts using one or more individual processes.

Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, and quenching, nitridation, carburization.

Inspections are very crucial for identifying defective or inferior products. We at Heng-Lay HK have implemented stringent quality checks to ensure each product is designed as per the drawings and relevant standards. Highly advanced measuring tools from Mitutoyo, Olympus, etc., are used to achieve high accuracy levels. Quality checks of high precision machined components for aerospace, biological medicine, and electronics industries are carried out using CMM, optical instrument, image measuring apparatus, laser instrument and so on.
