Product Description
Oblique full-cover cylindrical grinding machine adopts FC30 Meehanite high-grade cast iron base, and has been aging for more than 6 months to eliminate the pre-stress of the casting and guarantee no deformation. The whole base of the large CNC cylindrical grinding machine is internally constructed with a metric frame structure, with an overall net weight of 7.5 tonnes, which is firm and stable. It adopts Siemens 828D secondary development CNC system, which is simple and easy to learn, relieving customers from the pain of replacing skilled workers, and is equipped with Siemens servo motor, which has good compatibility and stable and accurate movement.
Structure
The main machine consists of bed, head, tail, grinding head, transmission and dust-absorbing device and other components. The head of the machine, the grinding head can be rotated at an angle, the fixture for grinding the thimble and chamfering the skin roller, the dynamic balancing frame, and the skin roller detector are ordered by the customer.
Oblique full-cover cylindrical grinding machine is a convenient, fast, flexible, precise and versatile cylindrical grinding machine with efficient control system and simple operation. The large CNC cylindrical grinding machine combines proven technology, good quality, high precision, low investment and great operating economy. The large CNC cylindrical grinding machine is a high-precision, flexible, general-purpose grinding machine for single-piece, small-lot and large-lot production, with a wide range of options and accessories for a wide range of applications. Even when grinding complex surfaces, it is possible to achieve reliability and precision. The large CNC cylindrical grinding machine offers good economy in small and medium batch sizes. The grinding machine has two drive feed axes of 12 N/m each and a high-efficiency grinding axis with a large 400 mm diameter grinding wheel. Cylindrical surfaces, end faces, conical surfaces, tapers, stator cam surfaces and other grinding operations can be performed in a single clamping with multiple cylindrical grinding and an integrated measuring system. Grinding of small to large quantities of workpieces.
Ontology
The body and components are cast by Meehanite high grade cast iron FC30, which is artificially normalized heat treatment and then treated by natural aging. Components are processed by YASDA, MITSUI SEIKI, TOSHIBA, ELB and other world-class equipment once clamping processing. Precision size can be up to micron level, to ensure high precision equipment basic components.
Automatic lubrication system
Machine guide rails and precision ball screws are continuously lubricated by automatic lubrication system to ensure longer service life and accuracy. The cooling system is separated from the body to eliminate vibration and favorable heat dissipation.
Automatic system
Standard use of Germany Siemens high-end CNC system, and after secondary development, fool type man-machine dialogue mode, with Siemens servo motor. There are many optional devices to choose from, including automatic end measuring device, automatic outside diameter measuring device, automatic hydraulic tailstock with pedal, automatic hydraulic chuck device, automatic grinding wheel balancing device, etc.
Grinding wheel head feed shaft
The grinding feed system is composed of Turcite coated V-flat track with precision spatula coupled with automatic lubrication system and precision grinding ball screw for smooth motion, excellent repetitive positioning accuracy and long track life.
Grinding wheel head feed shaft
The grinding wheel spindle adopts high precision dynamic and static compression spindle, which has the characteristics of high rotary precision, high dynamic stiffness, good vibration resistance, high grinding efficiency and good grinding surface quality.
Tail seat
The tail seat is designed to be both rigid and robust. A hardened alloy steel sliding cylinder encrusted in the cast iron body is designed to carry the MT4 top core. The jacking force of the sliding cylinder can be easily changed by adjustment knobs at the rear. Special accessories oil pressure tail seat with a pedal to facilitate unloading work parts.
Working head
The working head is a bearing type structure, the main shaft is fully sealed by the main shaft sleeve design, and then installed in a fixed position, and in the pulley outside the waterproof cover, can be waterproof, cutting fluid corrosion. Rotary cylinder can be installed, and can be matched with different workpiece clamp design to facilitate the grinding of different workpiece.
Grinding wheel dressing method
Different grinding methods can be selected according to different grinding workpiece.
