MAXA RockDrills Limited is a global diversified company with a network of production and commercial branches worldwide.
Our production process is designed to accommodate a range of customer specifications, while meeting our inhouse quality standards.
We formulate and develop the production steps required for the different designs of DTH rockdrilling tools. We utilize CNC programmable machines to execute various steps of our manufacturing processes, with selected machine tools, sequence and running profile.
The utilization of such programmable machines enables us to automate parts of our manufacturing process. We also make use of different types of machines to carry out other manufacturing processes.
The following diagram illustrates the major production process of our principal products
Our major production processes include.
- Cutting and Shaping. We utilize conventional lathes and CNC lathes to shape our alloy steel, which we obtain from our suppliers in cylindrical blocks, into the desired shapes, and also to include bores within the alloy steel blocks as appropriate, which will be further refined in the next steps of our manufacturing process.
- Processing of precise elements of products. We utilize our CNC machining centre, milling machines, slotting machines and drilling machines to cut our alloy steel blocks to incorporate finer details including precise holes and joints into our products.
- Smoothening, finishing and heat treatment. We then send our products to our grinding machines and sand blasting machines to refine the finishing of our products. Our sand blasting machine helps remove sharp edges from our products and our grinding machine helps to polish the surfaces of certain components, such as the piston within our down-the-hole hammers, and to minimize friction in the operation of our products, thereby increasing their durability.

The alloy steel bodies are then sent to our oven machine for heating: during the heating process, the drilled holes will expand in size, and the tungsten carbide buttons will then be inserted into the enlarged holes. The holes will contract upon cooling to hold the tungsten carbide buttons firmly in place. - Assembly of finished products. Finally, we put together the various components to assemble the final product.
