What is a fitter and what basic operating skills should fitters master

Hand tools are used to perform various machining of workpieces on vices and platforms, and sometimes to repair equipment. The basic operations include marking, filing, sawing, chiseling, drilling, countersinking, reaming, reaming, tapping, threading, riveting, straightening, bending, grinding, measuring, assembling and commissioning, simple heat treatment, oil painting, etc.

Safety knowledge, drawing knowledge, chiseling, sawing and filing, hole processing (drilling, reaming, reaming, countersinking), threading, correction and bending, riveting, scraping, grinding, etc.

Scribing, chiseling, sawing and filing Drilling (drilling, reaming, reaming, countersinking), threading, straightening and bending, riveting, bonding and soldering.

Scraping and grinding.

The basic contents of fitter's work are:

Master the safety operation procedures of fitters, misread mechanical drawings, marking, chiseling, sawing, frustration, drilling, reaming, countersinking, reaming, tapping and threading, correction and bending, riveting, scraping, grinding, technical measurement, simple heat treatment, etc., and can assemble, debug, and maintain components or machines.

Basic fitter skills include; Chiseling, filing, sawing, scribing, drilling, reaming, tapping and threading (see threading), scraping, grinding, straightening, bending and riveting, etc.

<>1.The name, model, specification, performance, structure and transmission system of the equipment for self-use.

2.Lubrication system, rules of use and maintenance methods for self-use equipment.

impact. 7.Mechanical drawing, tolerance fit, shape and position tolerance.

and the basics of surface roughness.

8.Knowledge of common mathematical calculations.

9.Basic knowledge of mechanical transmissions and typical mechanisms.

Exam question 1: Fitters all contain cutting operation skills, and the work of fitters is characterized by flexible processing. Manual work in cutting, mechanical assembly and repair operations, named after the operation of clamping the workpiece with a vise on the fitter table, the clamping work mainly includes chiseling, filing, sawing, scribing, drilling, reaming, tapping and threading (see threading), scraping, grinding, straightening, bending and riveting.

Fitter is the oldest metalworking technique in machine building. Flexible processing In occasions that are not suitable for machining, especially in the maintenance of mechanical equipment, fitter processing can obtain satisfactory results. Skilled fitters can process parts with complex shapes and high precision, and skilled fitters can process parts that are more precise and smooth than those processed by modern machine tools, and can process parts with very complex shapes that even modern machine tools cannot process, such as high-precision measuring tools, models, molds with complex beginnings, etc.

Invest in tools and equipment used by small fitters for processing** inexpensive and easy to carry. The production efficiency is low and the labor intensity is high. The processing quality is unstable, and the level of processing quality is affected by the technical proficiency of workers.
