Jewels have been used from time memorial for beautification and as precious gifts passed from one person to another. They are common among celebrities, famous people and even the ordinary folks as they bring a sense of class, elegance, luxury and happiness. They are manufactured from expensive durable materials such as diamond, gold, platinum, silver and bronze.
Due to their small size, complex shape and need to conserve the expensive materials, jewels must be made using special machines to produce high quality and good dimensional stability to ensure that customers are satisfied with them.
They must also have good aesthetic appeal and be durable. They must therefore be machined to perfect smoothness and flatness.
Precision jewel cutting using light duty lathes
Most rings are cast into cylindrical shapes and later machined using lathe and mill turns. They are also manufactured from rolled flat bars though this is not common for expensive products.
Due to the precision required, the production volumes are very low. In addition, most jewels are customized according to the client requirement which differ due to different physical dimensions e.g. size of fingers and neck.
Light duty lathe machines are used to fabricate most of these rings. The material is mounted on a chuck and various machining operations done. Turning of the internal surface is done to create an internal diameter that fits on the finger while outside diameter is turned to the specified size. Facing is done on the two opposite ends to smoothen them.
In addition, other processes such as drilling, tapping, chamfering and polishing and also done using this machine. A combination of these cutting operation results to the formation of the product. For example, chamfering gives the ring a wedge like edges while knurling results to a rough surface. All these operations are performed on light duty machines fitted with a small six jaw chuck to hold smaller work pieces without affecting the surface.
Contractors specializing in fabrication of many custom items have to make numerous rings that differ in design. This is achieved by using CNC machine. The jewels are automatically made by adjusting the tools and feed. In addition, these devices have the capacity of not only performing the turning, facing and other conventional lathe work but can also mill and perform cylindrical grinding.
The lathe allows a wide number of finishing operations to be done on the ring and jewels. In the lapping operation, the ring is rubbed continuously against another surface with an abrasive liquid between them. This removes a very tiny layer and smoothen the ring.

Nowadays, the tool room work and workshop machine activities; are done by repairers or through suitable lathe tools. A lathe is a tool utilized to perform various functions like turning, cutting, drilling, grooving, knurling, parting, threading etc. They are used to produce accurate products made from metal, plastic, wood etc. The basic lathe machine operations are as follows:-
Turning is an essential and important lathe operation. It is used to create circular objects and for reducing the diameter of the work. Taper turning refers to the process where the tool narrowly cuts the job at a specific angle. Knurling is done using a knurling tool; it has two slashed lined wheels that are pressed against the rotating work piece to produce a knurled object.
The drilling operation uses a drilling tool which is held in the tail stock and fed into the work by using a handle on tailstock. Threading is a precise operation, where the tool is fed into the job at a constant speed. This is done by attaching a carriage assembly with lead screws that are connected to the driving mechanism through gear trains. Two types of threading are external and internal threading.
Grooving is done before external threading by feeding the grooving tool perpendicular to the rotating work piece. Parting is done for cutting a work into smaller parts. Chamfering refers to slitting or cutting the edges of the object.
The major parts of a lathe machine are bed, headstock, saddle, tailstock, top slide; apron, cross slide, lead screw, countershaft, tool rest, chuck and gears. The bed is the base of a lathe, the chuck holds and spins the work piece; whereas the apron grips the gears, and the headstock allows the spindle to rotate at variable speeds. The tailstock holds the end of the work; and the carriage houses the cross slide, top slide and saddle.
Many types of lathes are available including the wood lathe. Here the cutting tool is operated manually by skilled workers to precisely form smooth curves and complex shapes on the work piece. The spindle is normally driven by a belt connected to the motor, and the speed can be varied manually. Lathe tools are held manually against the work, with the help of an adjustable tool rest; that is clamped to the base at a suitable position.
Engine lathes are machines with a longitudinal base, where the headstock and tailstock are mounted. It has an advanced spindle drive that runs at variable speeds; the selectable gears help to operate the machine at higher speeds. The lathe cutting tools are moved against the work using hand wheels; or automatically using a lead screw that is power driven by gears in the headstock. The carriage moves back and forth on the bed for longitudinal turning. The cross slide and compound rest are mounted above the carriage to enable cross and angular cutting.
Finally during any lathe machining operation, always take necessary precautions; even if you are an expert, or are handling an important process.
The lathe is indeed a great invention and a very helpful machine, used for numerous purposes since the ancient times. The earliest type of lathe was the potter’s wheel, which is being utilized to shape clay pots and earthen objects even today. The lathe machine is basically a machine tool that revolves the work piece on its axis to carry out a variety of operations that includes cutting, shaping, turning, drilling, sanding, bending etc.
