As for the transmission, it protects the motor from overload. You may also be interested in the presence of interchangeable gears, which allow threading with different pitches. The movement of calipers can be transverse and longitudinal. In order to sharpen small parts, the manufacturer has provided a rotary caliper. It is impossible not to mention the huge selection of equipment. Consumers love that the tailstock has a lateral offset. The described turning "Corvette 403" has a table that allows you to fine-tune the thread cutting settings.
Instructions for use
The lathe is used to process metal and various types of plastics. It works from a single-phase alternating current network with a voltage of 220 V. Operation is possible at temperatures from 1 to 35˚С. The relative humidity of the air can reach 80%. In this case, the temperature should not be higher than +25˚С.
If the lathe "Corvette403" was brought indoors during the cold season, do 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
Before turning on the machine, it is important to make sure that all tools are removed from the equipment. The workplace must be kept clean and the machine must be fenced off while the equipment is in 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 rubbed 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 good lighting in the workplace. There must be freedom of movement around the machine. The device should not be overloaded. After reading the reviews about the "Corvette 403", you will understand that it is important to control the serviceability of parts and the correct adjustment of moving parts, as well as connections. The defective part must be repaired or replaced. Disconnect the power plug from the power outlet before starting any adjustment or maintenance work. Accessories must be recommended by the manufacturer.
Safety measures during work
Ifsomething seemed abnormal to you in the operation of the machine, you should stop using it. It is necessary to protect the cord from heat and contact with water and oil, as well as chafing it against sharp edges. Once the machine is started, let it idle for a while. If at this time you hear extraneous noises or feel an excessively strong vibration, the machine must be turned off by connecting the plug from the outlet.
Equipment should not be turned on until the cause of the malfunction has been identified and corrected. The instruction for the "Corvette 403" states that it is impossible to perform turning operations if covers of rotating units or protective covers are not installed. For one pass it is impossible to carry out turning deeper than 0.3 mm. The cutters in the holders must be well fixed. Chips should not be wound on the cutter, as well as on the workpiece being machined. Chips should not fall on the lead screw. The workpiece must be securely fastened before starting work. The machine must be stopped to check the position of mating parts and the condition of fasteners, as well as mechanisms and assemblies after 50 hours of operation.
Installation and assembly
Characteristics "Corvette 403" - that's not all you need to know before you start. For example, the device should be installed on a heavy, sturdy workbench that is of sufficient height. The operator must not bend over during operation. It is important to be careful when moving the machine according to its weight. The equipment must be well secured to a sturdy workbench. This will guarantee the safety and stability of the work. On the working surface of the workbench, it is necessary to drill 4 holes, fastening with bolts and washers, which are not supplied. The machine is attached to a workbench with a pallet.
In conclusion
In order to make the right choice, if you plan to purchase a lathe, you must consider how the bed rails are attached. 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 are subjected to high loads, so the bed must be made of durable material. It is best if it is cast iron. The rails can be fastened to the vertical posts by bolting. Sometimes welding is also used for this.
When organizing a workplace, it is important to take the choice of cabinets especially seriously. Its main purpose is to ensure that the frame stands up without distortions, which can lead to product defects. If you are still undecided 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, then there can be 2 pedestals. For wide and long machines that are designed for metal processing, the number of pedestals can be increased to 4.
