Description
Introduction to vertical honing machine machine tool performance:
Main functions of vertical honing machine tools:
The 2MK2212 CNC vertical honing machine is an ideal machine for machining deep hole parts. This machine is suitable for honing of various hydraulic cylinders, spindle holes, cylinder holes and cooling holes. The dimensional accuracy of the hole diameter of the machined parts can reach IT7~ IT9, and the surface roughness of the inner hole is Ra0.16~ Ra1.6 μ m.
It can be honed as a whole or partially; During local honing, the errors of taper, ellipticity and local aperture of the workpiece can be corrected.
All castings of machine tools adopt the design concept of box structure, and are optimized by finite element analysis, so that they have the characteristics of reasonable quality, high rigidity and high precision.
All castings of the machine tool are made of high-strength cast iron and resin sand casting. All castings are normalized after casting to eliminate internal stresses generated during casting. After roughing, normalization is carried out again to further eliminate the internal stress generated in the casting process, and at the same time, the machining stress generated during roughing is removed, so that it has good accuracy and stability.
Overview of the overall layout and main component structure of the machine tool:

Reference drawing of overall appearance of machine tool
The general layout of this machine tool: The machine tool is composed of base, workbench, spindle box, servo tool expansion system, column, guide frame, cooling system, numerical control system and other main components.
The main castings of this machine: base, spindle box, column.
Base and workpiece table:
A movable workbench is installed on the base, and the moving direction of the workbench is front and back, which is convenient for clamping workpieces. Workbench moving system, consists of servo motor, ball screw pair, etc.
The workbench is used for mounting fixed workpieces, and the center of the workbench has a positioning hole coaxial with the height of the spindle box spindle, which is used for mounting the tooling fixture. Special tooling fixtures are made by users. The table has a T-shaped slot parallel to the direction of movement for fixing the workpiece or tooling fixture.
Spindle box and servo tool expansion system:
The spindle box is used to drive the tool to rotate and provides powerful torque. The spindle box transmission system is composed of servo motor, reducer and so on.
Servo cutter expansion system is used to control the expansion and contraction of honing tool. The servo cutter expansion system is composed of servo motor, precision planetary reducer, ball screw, etc. The expansion and contraction of the honing head is controlled by the servo motor, which can realize both the constant pressure feeding and the quantitative feeding of the honing head.
Column:
The upright column is fixed on the base, and a linear guide rail is installed for the reciprocating motion of the spindle box. The reciprocating motion system of the spindle box is composed of servo motor, speed reducer, ball screw pair, etc. The ball screw pair has the advantages of smooth transmission, high transmission efficiency and high precision. The upright column is equipped with organ-type telescopic protection, which effectively protects the linear guide rail and the ball screw pair and increases their service life.
Guide frame:
The guide frame shares a linear guide rail with the reciprocating motion of the spindle box, which is used to guide the honing tool.
Cooling system:
The cooling system adopts the external oil injection type oil supply of the tool, and its main function is to lubricate and cool the cutting area with circulating liquid medium, and remove chips at the same time.
The cooling system adopts the above-ground oil tank structure, which is composed of cooling pump, magnetic roller filter, paper bag filter, etc.
Machine Tool Protection:
The machine tool adopts a non-completely enclosed protective structure, which is beautiful in appearance, can effectively prevent cutting fluid from splashing and protect the environment.
CNC system:
The independent electrical cabinet has good dust-proof effect. The cabinet is equipped with a cooling system, which makes the electrical devices work in a suitable temperature environment, thus increasing the service life of the devices and ensuring the stability and reliability of the control system.
