The choice of a lathe is an individual task. In this case, it is important to consider several factors, for example, appointment in the workplace. The weight and dimensions of the machine will depend on the size of the workpieces, the number of operations and the length of the workpieces. When buying it for processing large batches, it is better to prefer CNC equipment with a multi-spindle head, which is especially important when a part should be machined with several cutters.
In order to make the right choice, you should consider several options, you need to start with one of the many, which is represented by a modern assortment of relevant stores. Among others, the "Corvette 403", which will be discussed in the article, should be highlighted.

The aforementioned lathe model is quite expensive. The price is 89600 rubles. This device is designed to work on metal and is capable of performing a huge number of tasks, among them it should be highlighted:
- trimming;
- turning
- drilling.
Corvette 403 supports a wide range of feed speeds. One cannot but mention the purity of rotation of the working parts. You can use the unit for processing different materials, namely:
Suitable machine for working in industrial and private workshops.

The cross course of a support is equal to 110 mm. You may also be interested in the dimensions of the Corvette 403. They are equal to 1250x480x475 mm. The cross course of a support is equal to 110 mm. The equipment weighs 120 kg. The longitudinal stroke of the caliper is 50 mm. The distance between the centers is 750 mm. The spindle speed can vary from 100 to 1800 rpm.
Machine reviews
Before making the final choice, you should familiarize yourself with the opinions of consumers. Among the positive features they note:
- fine adjustment;
- emergency switch;
- operator safety.
As for the adjustment, special handles are responsible for this function. They allow you to adjust the automatic feed direction and speed. Home craftsmen especially emphasize that the machine has an emergency switch. It is necessary to instantly stop the engine.
The Corvette 403 also provides operator safety. It is guaranteed by a protective transparent shield. Additional advantages of the master are:
- belt drive;
- reverse automatic feed;
- reverse spindle rotation;
- spindle rotation adjustment.
As for the transmission, it protects the motor from overloads. You may also be interested in the presence of interchangeable gears that allow you to thread with different steps. The movement of the calipers can be transverse and longitudinal. In order to sharpen small parts, the manufacturer has provided a rotary caliper. One cannot but mention the huge selection of equipment. Consumers like the tailstock to have a lateral displacement. On the described turning "Corvette 403" there is a table that allows you to precisely adjust the thread cutting settings.
Instruction for use
A lathe is used to process metal and various types of plastics. It works from a single-phase AC voltage of 220 V. Operation is possible at a temperature of 1 to 35 Β° C. The relative humidity in this case can reach 80%. In this case, the temperature should not be higher than + 25Λ.
If the Corvette 403 lathe was brought into the room during the cold season, you should not unpack it or turn it on for the next 8 hours. Allow the equipment to warm up to ambient temperature. If this recommendation is neglected, then, due to condensed moisture, the elements of the electric motor may fail.
Safety precautions
Before turning on the machine, it is important to make sure that all tools are removed from the equipment. The workplace should be kept clean, and the unit should be enclosed during operation. It is important to avoid cluttering the workspace with foreign objects. Do not start operation if the floor in the room is slippery, for example, covered with grated wax or sawdust. You can make sure that the relative humidity is not more than 80% if you plan to turn on the equipment.
It is important to take care of the good illumination of the workplace. Around the machine should ensure freedom of movement. The device should not be overloaded. After reading reviews of the Corvette 403, you will realize that it is important to control the health of parts and the correct adjustment of moving parts, as well as joints. A defective part must be repaired or replaced. Before starting setup or maintenance work, disconnect the power plug from the electrical outlet. Accessories should be recommended by the manufacturer.
Work safety measures
If something seemed abnormal in the operation of the machine, you should stop using it. It is necessary to protect the cord from heating and the ingress of water and oil, as well as its grinding against sharp edges. Once the machine is started, it should be allowed to idle for some time. If at this time you hear extraneous noise or feel excessively strong vibration, the machine must be turned off by connecting the plug from the outlet.
The equipment should not be turned on until the cause of the malfunction is identified and rectified. The instructions for the Corvette 403 states that turning operations should not be carried out if the covers of the rotating units or protective covers are not installed. In one pass, you cannot turn deeper than 0.3 mm. Cutters in holders should be well fixed. Chips should not be wound on the cutter, as well as on the workpiece to be processed. Chips should not fall on the lead screw. Before starting work, the workpiece must be reliably strengthened. The machine must be stopped to check the position of the mating parts and the condition of the fasteners, as well as mechanisms and components after 50 hours of operation.
Assembly and assembly
Characteristics "Corvette 403" - this is not all that you should know before starting work. For example, the device should be mounted on a heavy, durable workbench that is of sufficient height. The operator should not bend over during operation. It is important to be careful when moving the machine, taking into account its weight. The equipment should be well fixed on a solid workbench. This will guarantee safety and stability. It is necessary to drill 4 holes on the work surface of the workbench by fastening with bolts and washers that are not supplied. The machine is attached to a workbench with a pallet.
Finally
In order to make the right choice, if you plan to purchase a lathe, it is necessary to take into account the method of mounting the bed guides. The more stable, massive and reliable the bed, the higher the accuracy of the machine and less vibration during its operation.
When metal processing is carried out, the equipment guides experience high loads, so the bed should be made of durable material. Best if it is cast iron. The fastening of the rails to the uprights can be done by bolting. Sometimes welding is also used for this.
When organizing a workplace, it is important to take the choice of a cabinet particularly seriously. Its main purpose is to make the bed stand without distortions, which can lead to marriage of products. If you still have not decided on the choice, then you should pay attention to the length of the machine and its weight. If the device is short and weighs no more than 1 ton, the pedestals can be 2. For wide and long machines that are designed for metal processing, the number of pedestals can be increased to 4.
