CNC Vertical Honing Machine

2MK2216×1m CNC vertical honing machine

 

Machine tool performance brief:

Main functions of the machine tool:

2MK2216 CNC vertical honing machine tool is an ideal machine tool for machining deep hole parts. This machine tool is suitable for honing various hydraulic cylinders, spindle holes, cylinder holes, and cooling holes. The hole size accuracy of the machined parts can reach IT7~IT9, and the surface roughness of the inner hole is Ra0.2~Ra1.6μm.

It can be honed as a whole or partially; During local honing, the taper, ellipticity, and local aperture errors of the workpiece can be corrected.

All castings of the machine tool adopt the design concept of box structure, and through finite element analysis and optimization design, make them have the characteristics of reasonable quality, high rigidity, high precision and so on.

All castings of the machine tool are cast using high-strength cast iron and resin sand. All castings are normalized after casting to eliminate internal stress generated during the casting process. After roughing, normalizing is carried out again to further eliminate the internal stress generated during the casting process, and at the same time, the processing stress generated during roughing is removed, so that it has good precision and stability.

Overview of the overall layout and main component structure of the machine tool:

Overall layout of this machine tool: The machine tool consists of main components such as a base, workbench, spindle box, servo tool raising system, column, cooling system, and CNC system.

The main castings of this machine tool are: base, spindle box, and column.

Base and workpiece table:

A movable worktable is arranged on the base, and the worktable moves in the front and rear directions, which is convenient for clamping workpieces. The workbench moving system consists of servo motors, ball screw pairs, etc.

The workbench is used for installing fixed workpieces, and the center of the workbench has a positioning hole coaxial with the height of the spindle box, which is used for installing tooling fixtures. Special tooling fixtures are made by users themselves. The workbench has a T-slot for fixing workpieces or tooling fixtures.

Spindle box and servo tool raising system:

The spindle box is used to drive tool rotation and provides strong torque. The spindle box transmission system consists of servo motors, reducers, etc.

The servo tool raising system is used to control the raising and retraction of honing tools. The servo tool raising system consists of a servo motor, a precision planetary reducer, a ball screw, etc. The expansion and contraction of the honing head is controlled by a servo motor, which can realize both constant pressure feed and quantitative feed of the honing head.

Column:

The column is fixed on the base, and a linear guide rail is installed for the reciprocating movement of the spindle box. The spindle box reciprocating motion system consists of a servo motor, a reducer, a ball screw pair, etc. The ball screw pair has the advantages of stable transmission, high transmission efficiency, high precision and the like. The column is equipped with accordion-type telescopic protection, which effectively protects the linear guide rail and ball screw pair and increases its service life.

Guide frame:

The guide frame and the spindle box share a linear guide rail for reciprocating motion, which is used for positioning and clamping the upper end of the longer workpiece and guiding the honing tool.

Cooling System:

The cooling system uses an oil injection system outside the tool, and its main function is to use a circulating liquid medium to lubricate and cool the cutting area, while removing chips.

The cooling system adopts an above-ground oil tank structure, which consists of a cooling pump, a magnetic roller filter, a paper bag filter, etc.

Machine tool protection:

The machine tool adopts a non-fully enclosed protective structure, which has a beautiful appearance and can effectively prevent cutting fluid from splashing and protect the environment.

Control System:

Control system: Delta PLC equipped with industrial screen.

The independent electrical cabinet has excellent dustproof effect. The cabinet is equipped with a cooling system, which enables the electrical components to operate in a suitable temperature environment, thereby increasing the service life of the components and ensuring the stability and reliability of the control system.

Machine tool working conditions:

Power supply: Three-phase five-wire power supply, 380V ± 5%, 50Hz ± 1Hz.

Working environment temperature: 0℃~40℃. (No freezing)

Ambient humidity below 80% (no condensation)

Altitude: 0~2000m

Installation site requirements:

Avoid being affected by external vibrations; Avoid exposure to corrosive gases or liquids; Direct sunlight should be avoided on the surface of the machine tool; It should be kept away from direct strong cold or hot air sources; Dust (metal dust, sand, etc.) pollution should be minimized.

Machine tool installation and commissioning conditions (user preparation):

Foundation requirements: Users can create a foundation based on the foundation map (normal factories harden the ground, so a foundation is not required).

Secondary watering: The user prepares to water the grouting material and tools secondarily (if foundation construction is required).

Input power supply: Three-phase five-wire power supply, 380V ± 5%, 50Hz ± 1Hz. The user provides a cable from the workshop power supply to the electrical cabinet.

Cleaning oil and utensils: 20 liters of gasoline or kerosene, several cotton cloths provided.

Cutting oil: Honing extreme pressure cutting oil, kinematic viscosity 40℃: 2-5 mm²/s, flash point ℃≥140, usage approximately 500 liters.

User prepares lifting equipment and tools for lifting.

Tools, auxiliary tools, and fixtures for machine tool test runs (if the user has not placed an order).

Lubrication station: ISO-L-HM32, 3 liters.
