Instrument Lathe

Introduction to instrument lathe

The instrument lathe is a simple horizontal lathe. Generally speaking, the largest workpiece machining machine with a diameter of 250mm or less is mostly an instrument lathe.

The instrument lathe is divided into ordinary type, hexagonal type, finishing type and automatic type.

Working principle

The instrument lathe is fast clamped by the spring collet, the motor directly drives the main shaft, the large and small discs are operated by the hand, and the vertical and horizontal positioning controls the turning.

Some instrument lathes are equipped with flanges, tailstocks, and die-and-threaded devices.

Can process outer circle, inner circle, cut, end face, slot, turning taper, drilling, reaming, tapping, milling, grinding functions.

Widely used in small parts such as electrical appliances, fasteners, automobiles, motorcycle parts, instrumentation, hardware and electrical appliances, cultural and educational supplies, film and television equipment, mechanical and electrical products, plumbing fittings, valves, bearing rings, shafts, etc. The production and processing is the most ideal high-efficiency equipment in the hardware machining industry.

Thanks to the push-type feed, the spring collet is quickly clamped, the thimble-type limit device, and the quick-handle operation, the motor directly drives the spindle to run, and the positioning controls turning.

Continuous processing of a single fixed type of workpiece and shape can increase the work efficiency by more than 10 times compared with the ordinary lathe.

Especially suitable for the processing of large quantities and small parts. Can replace other machine tools to save energy consumption.

Troubleshooting

Axle box overheating

(1) The spindle is overheated for a long time and generates heat.

Solution: Adjust the bearing clearance, properly reduce the spindle speed (not exceed the maximum speed of the machine design of this model), high-speed grease on the bearing.

(2) The spindle bearing clearance is too tight and generates heat.

Solution: adjust the bearing clearance of the spindle.

(3) The spindle bearing is rusted and worn, and may cause wear or rust of the spindle part when used for a long time or in a humid environment; if the storage time is too long, the bearing may be rusted.

Solution: Clean the bearings to adjust the grease or replace the bearings.

Bed deformation

Improper installation of the machine tool can cause the machine bed to be twisted and deformed, which can cause the large carriage to move too tight or get stuck.

Solution: Loosen the anchor bolts to restore and reinstall them to ensure the level of the foot and the work surface (this solution is the solution for the new machine when it is installed).

Rail feeding

Loosen the large pallet guard screws and remove the large pallet guards and guard pads.

Then loosen the large pallet pressure plate screws, remove the large pallet pressure plate, and wash the carriage and guide rail with kerosene.

It takes a while to replace the size of the pad guard pad (wool felt) to prevent iron filings from entering.
