What Is a Hand Lathe?

Ordinary lathes are horizontal lathes that can perform various processes on various types of workpieces such as shafts, disks, and rings. They are often used to process the internal and external rotating surfaces, end faces and various internal and external threads of the workpiece. The corresponding tools and accessories are also used. Drilling, reaming, tapping and knurling. Ordinary lathes are the most widely used ones, accounting for about 65% of the total number of lathes. They are called horizontal lathes because their spindles are placed horizontally.

1. Inspection before driving

1.1 According to

The normal use of ordinary lathes must meet the following conditions: the power supply voltage of the machine tool is small, the ambient temperature is less than 30 degrees, and the relative humidity is less than 80%.

1. Environment requirements for machine tool position

The location of the machine tool should be far away from the vibration source, avoid direct sunlight and heat radiation, and avoid the influence of humidity and airflow. If there is a vibration source near the machine tool, anti-vibration grooves should be set around the machine tool. Otherwise, it will directly affect the machining accuracy and stability of the machine tool, will cause poor contact of electronic components, cause failure, and affect the reliability of the machine tool.

2.Power requirements

Generally, ordinary lathes are installed in machining workshops. Not only the environmental temperature changes greatly, the use conditions are poor, but also various mechanical and electrical equipment, which cause large fluctuations in the power grid. Therefore, the location where ordinary lathes are installed requires strict control of the power supply voltage. Power supply voltage fluctuations must be within the allowable range and remain relatively stable. Otherwise it will affect the normal operation of the CNC system.

3.Temperature conditions

The ambient temperature of ordinary lathes is less than 30 degrees, and the relative temperature is less than 80%. Generally speaking, an exhaust fan or a cooler is installed inside the numerical control electric control box to keep the electronic components, especially the central processor's working temperature is constant or the temperature difference changes little. Excessive temperature and humidity will reduce the life of the control system components and increase failures. As the temperature and humidity increase, the increased dust will cause adhesion on the integrated circuit board and cause short circuits.

4. Use the machine according to the instructions

When using the machine tool, the user is not allowed to arbitrarily change the parameters set by the manufacturer in the control system. The setting of these parameters is directly related to the dynamic characteristics of each part of the machine tool. Only the gap compensation parameter value can be adjusted according to the actual situation.

The user cannot change the machine tool accessories at will, such as using a hydraulic chuck that exceeds the specifications in the manual. When setting up the accessories, the manufacturer takes full account of the matching of the parameters of each link. Blind replacement causes mismatch of parameters in various links, and even causes unexpected accidents. The pressure of using hydraulic chuck, hydraulic tool holder, hydraulic tailstock, and hydraulic cylinder should be within the allowable stress range, and it is not allowed to increase arbitrarily.
