CNC Lathe Description

CNC instrument lathe is a simple CNC horizontal lathe. Generally speaking, most of the machine tools with the largest workpiece processing diameter of less than 250mm belong to instrument lathe. Instrument lathes are divided into ordinary type, hexagonal type, finishing type and automatic type. The lathe bed of CNC instrument lathe adopts the overall structure, resin sand modeling, and the guide rail adopts high-frequency quenching and grinding process, so that the machine tool has good wear resistance and precision retention. The stiffener makes the bed have excellent stiffness, vibration resistance and section distortion resistance. The bed guide rail is fully enclosed with telescopic steel plate protective cover, which effectively protects the service life of the guide rail from damage. CNC instrument lathes adopt spring collet for quick clamping, the motor directly drives the spindle, large and small discs for quick hand wrench operation, and vertical and horizontal positioning to control turning. Some instrument lathes are equipped with flange, tailstock device and die thread following device, which can process outer circle, inner circle, cutting, end face, cutting groove, turning taper, drilling, reaming, tapping, milling, grinding and other functions. It is widely used in the production and processing of small parts such as electrical appliances, fasteners, automobile and motorcycle accessories, instruments and meters, hardware and electrical appliances, cultural and educational supplies, film and television equipment, electromechanical products, plumbing fittings, valves, bearing rings, shafts and small workpieces such as glasses manufacturing. It is the most ideal high-efficiency equipment in the hardware machining industry.

Causes and solutions of spindle box heating of NC instrument lathe:

1. The spindle runs over speed for a long time and generates heat. Solution: adjust the bearing clearance, appropriately reduce the spindle speed (which shall not exceed the design maximum speed of the machine tool), and apply high-speed grease on the bearing.

2. The main shaft bearing clearance is too tight and generates heat. Solution: refer to section 4 to adjust the bearing clearance of the main shaft.

3. The main shaft bearing is rusted, worn and heated, and parts of the main shaft may be worn or rusted after long-term fatigue use or in humid environment; Long storage time without use will also cause bearing rust. Solution: clean the bearing, adjust the grease or replace the bearing.
