Machines for processing wooden blanks today are used not only in production and in professional workshops. At home, a small turning unit allows you to accurately perform complex pieces of furniture, dishes, decorative accessories, carved ornaments, etc. For such tasks, the domestic Enkor Corvette-71 machine is optimally suited, the dimensions of which are designed for operation in a workshop, utility block or garage.
Machine design
The model is an electric wood turning machine. The unit is based on a metal frame, which implies a desktop installation with the possibility of regulation in height and position of the guides. Among the main assembly parts of the Corvette-71 machine, it is worth highlighting the following:
- Headstock of the machine.
- Front spindle.
- Tool holder.
- Incisal holder support.
- Tool holder support fixing knob.
- Turning faceplate.
- Tailstock quill.
- Tailstock center section.
- Rear quill locking knob.
- Tailstock locking knob.
- Tailstock.
- Handwheel for moving the quill.
- Magnetic starter supply.
- Electric motor.
The design of the machine allows you to process workpieces with a diameter of up to 250 mm and a length of up to 455 mm. At the same time, work with metal, stone, asbestos-cement and rubber products is not allowed. Limitations regarding the operating mode itself should also be taken into account. The capacity of the unit is not designed for a continuous processing format.
Specifications
The power potential and the technical design of the model are designed for processing small-format workpieces, which also corresponds to many hand tools. Another thing is that the design and guides with locks facilitate work operations on the Corvette-71 machine. The turning unit in this modification has the following characteristics:
- Motor power - 370 W.
- Motor type - asynchronous electric.
- Required mains voltage - 220 V.
- Number of speeds – 5.
- Machine spindle speed - from 760 to 3150 rpm.
- Machining diameter - up to 250 mm.
- Workpiece length - up to 455 mm.
- The distance between the centers of gripping the part - 420mm.
- The dimensions of the machine are 83 x 30 x 43 cm.
- Design weight - 38 kg.
Additional functionality
The owner of the machine has at his disposal several adjustment options, which are implemented thanks to the spindle and belt drive. This allows you to adjust the processing speed to the desired frequency, with an emphasis on the characteristics of the workpiece and the parameters of mechanical action. There are also several safety additions to the Corvette-71 working system, some of which are related to electrical support. For example, in case of overloads in the network, a special RAM-type protection unit is provided, and a magnetic starter prevents the machine from starting spontaneously after a power outage. As for the functions and processing modes, at the basic level, the solution of grinding and polishing tasks is provided, but with proper skills in working with turning equipment, the user will be able to perform high-precision cutting operations.
Machine instruction manual
You can start connecting and further operating the machine only after it is securely installed on a workbench or other stable surface. Connection is made only to a 220 V socket with grounding. Small voltage deviations of 10-20 V are allowed, but only in the form of a temporary error at the time of mains drops.
Turning on the lathe "Korvette-71" is performed through the green starter button. From now on, the machine must not be left unattended until it iswill be disabled by the red button. Adjustment of the processing mode is made through the headstock mounting bolt. When it is loosened, it will be possible to move the platform with the engine, change the parameters of the position of the workpiece and the speed of rotation of the spindle. The tailstock is displaced by performing adjustment manipulations with the locking knob. It also changes position relative to the bed. The workpiece is installed tightly, but in such a way that there remains the possibility of accurate mechanical action by the tool holder. The possibility of cutting is assessed visually - after fastening the part, it is enough to scroll it around its axis, checking the points of contact with the processing tool.
Work Safety
During the organization of work with the unit and in the process of direct processing of materials, the following safety rules recommended by the equipment manufacturer should be observed
- The condition of safety devices and accessories should always be kept under control.
- Tools, blanks and other items with materials should not be near the machine without the need.
- The room itself, where the Corvette-71» is used, must have good lighting, ventilation and fire safety equipment.
- The operator must wear appropriate equipment - an apron, gloves, anti-slip shoes, a respirator and goggles.
- During operation, it is forbidden to reach through the machine, trying to getthe desired detail. The movements of the operator must not potentially disturb his balance and entail additional risks of injury.
- The machine can only be used for its intended purpose - this applies to processing materials, their parameters and operations performed.
Machine maintenance
On a regular basis, and especially after each working session, it is necessary to clean the machine from dirt and dust. It is desirable that a dust collector pipe be connected to the equipment during operation, which minimizes the accumulation of wood chips on the machine and in the operating area. With regard to the machine, the most care should be given to the engine and headstock surfaces, where the largest amounts of dust accumulate. It is recommended to cover the Corvette-71 machine with car wax, which will contribute to the smooth movement of the caliper and tailstock. Threaded connections and handles should be coated with machine oil and special grease to ensure running stability. A major inspection with maintenance preventive measures is carried out at least once every six months, subject to regular use of the equipment. This applies to cleaning, flushing, lubricating and adjusting operations. If problems are found, it is necessary to start technical recovery operations, if possible without the participation of specialists.
Possible problems and how to fix them
In addition to structural failures and damage that can be solved by replacing individual elements, it is necessary to prepare forfollowing motor problems:
- The power unit does not start. More likely to be wiring problems, poor mains performance, and low voltage. Directly "Corvette-71" is checked in parts of the stator, switch and fuse.
- The engine is not running at full capacity. Usually this problem is observed in cases of low voltage or cable damage - you should check the winding and test the network with a multimeter.
- The engine is overheating. Also, various kinds of malfunctions of the mains and the connecting cord are not ruled out, but there may also be problems with the breaker. In addition, thermal and physical overloads are quite possible if the machine is operated for a long time at peak capacities.
Positive feedback about the machine
The owners of the model characterize it as a light, reliable and easy-to-use machine, optimal for domestic use. The high quality of the assembly, in particular, is evidenced by the tight bow of the cast bed and the tailstock without play. In the working process, "Encore Corvette-71" also shows its best sides - there are no beats, vibrations, and even the noise characteristic of such machines. As for load limits, many reviews indicate the ability of the unit to withstand many hours of processing sessions, although the manufacturer recommends taking 15-minute pauses every half hour.
Negative feedback about the machine
Usually lathe models of machine tools are valued not onlyfor lightness and small size, but also for ergonomics when performing physical manipulations. In this case, opinions about ergonomics are ambiguous. So, many owners criticize the performance of the Corvette-71 plastic handles. Reviews note not only the poorly thought-out configuration of their placement, but also the structural fragility. The same applies to the pressure washers, which determine the position of the tailstock in the mobile stop. It happens that the loosening of the bolts leads to a skew of the clamp, as a result of which the washer shifts and deforms over time.
Conclusion
The Enkor company is considered one of the leading developers of Russian machine tools, designed, among other things, for the domestic use segment. However, it still manages to withstand tough competition with foreign analogues only in the price parameter. In some ways, the Corvette-71 wood lathe could be an exception to this rule, since a serious step towards development was made in its functional and structural basis. Especially if you take into account the calculation for operation at home. And yet the cost is about 18-20 thousand rubles. can not be called low for models of this level. In addition, it is worth focusing on minor flaws, the presence of which is obviously due to the desire of the creators to save money. On the other hand, the basic level of quality of the functions performed in the eyes of an ordinary undemanding master leaves such shortcomings in the background. According to the general characteristics of woodworking, thisthe unit does converge with semi-professional models, if you do not make allowances for the power potential.
