Application of Integrated CASNUC 2100e CNC System in Oblique Cylindrical Grinder

The inclined-axis grinder can be used to grind the outer circle and also to grind the end surface. It is used to grind shoulder and cylindrical shafts or gear shafts in industries such as automobiles, motorcycles and compressors.

Jinan No. 4 Machine Tool Plant newly developed a slant axis function grinder, which was selected by Aerospace Numerical Control's 2100eG CNC system. After on-line debugging, it fully meets the requirements for use.

The 2100eG CNC system can be used for straight-cut cylindrical grinding machines and cylindrical grinding machines with inclined axis. The technical specifications are as follows:

(1) Control the X axis, Z axis, and spindle.

(2) The cylindrical grinding machine can realize the single-acting and linkage function. The angle of the inclined shaft can be set between 0.000° and 80.000°.

(3) E-parameter function, with +, -, *, / operation, judgment, jump function, can read the current position of X, Z, axis coordinates for grinding after dressing processing.

(4) The numerical control system can receive the signal of the processor probe.

(5) Emergency retreat function: When an emergency situation occurs, it can automatically perform emergency retreat to avoid accidents.

(6) The motor is processed at a low speed, the lowest speed can be performed 0.001mm/min, and the highest speed can reach 100m/min.

Single action: When the X axis is moved, only the X axis moves.

Linkage: When the X axis is moved, the Z axis also moves so that the X axis moves vertically with the Z axis.

Wheel dressing procedure:

E80: X trims the parameters to the grinding wheel and enters the data into the E parameters after the tool is set

E81: Z wheel dressing parameters
