Component Features
(1) The equipment is controlled by two-axis servo, with the worktable moving left and right as the Z-axis and the wheelhead moving back and forth as the Z-axis. They are driven by servo motors respectively. The bed has a reasonable structural layout, is made of high-strength and wear-resistant FC30 high-grade cast iron, and has undergone more than two years of natural aging treatment and two artificial tempering treatments, so that the stress is fully released and the bed has good rigidity and precision retention. The casting surface is smooth and flat.
(2) The equipment has a reasonable structural design, good static precision, dynamic rigidity and thermal stability. It has high dynamic rigidity, high stability during continuous operation and good accuracy retention, and can achieve micro-feeding without creep. The machine tool is suitable for long-term continuous processing, and the working accuracy can be maintained for more than 10 years under normal use conditions.
(1) The X-axis and Z-axis guide rails are V-flat guide rails. The guide rails have undergone a manual scraping process and are coated with imported wear-resistant material. The unique oil supply system, low friction coefficient, wear resistance, good shock resistance, and long service life ensure stable low-speed operation, accurate micro-feeding, and stable processing accuracy. The guide rails are lubricated automatically at regular intervals. The lead screw is continuously lubricated at fixed points, and the lead screw positioning bearing is lubricated with grease.
(2)The lead screw is a Taiwanese PMI C1 lead screw, and the positioning bearing is an NSK brand P4 grade.
(1) The wheelhead feed method is a straight-line guide rail with a straight spindle and a straight wheel.
(2) The wheel spindle motor is air-cooled, and the motor is placed inside a protective cover to prevent corrosion and contamination from the coolant.
(3) The radial runout of the grinding wheel spindle is ≤0.0015mm.
(4) The grinding wheel spindle adopts a high-rigidity, high-precision bearing-type spindle, which has strong cutting force, high precision, good stability, and is easy to maintain.
(1) The grinding spindle is equipped with a high-rigidity, high-precision bearing spindle, which has strong cutting force, high precision, good stability, and is easy to maintain.
(2) The spindle is mounted on the external grinding wheel frame, which is easy to use and operate.
(1) The headstock motor is driven by a Delta servo motor, which has good linearity and stable output.
(2) The headstock spindle is supported by high-precision German FAG bearings, and driven by a servo motor to rotate the workpiece via a pulley, ensuring good linearity and high roundness of the ground product.
(1) The tailstock is highly rigid and sturdy, with a sleeve design and easy adjustment of the clamping force, which can be adjusted at will using the adjustment knob.
(1) CNC numerical control system, integrated USB interface, and mechanical keys. The machine tool is equipped with dedicated user functions, including coordinate setting function, grinding wheel shape parameter setting function, dressing parameter setting function, compensation function, grinding parameter setting function, etc., for user-friendly operation. There is a separate operating table.
(2) It supports the function of reading machine status data and alarm data via Ethernet for analysis by the server, and supports the function of transferring CNC programs between the CNC machine tool and the server via Ethernet, and the centralized management of CNC programs on the server.
(3) The CNC software includes external grinding, external groove left and right end faces, left and right fillets, profile grinding programs, and various wheel dressing programs. It has high-precision linear and circular interpolation grinding functions. It can realize independent feeding of the X-axis, independent feeding of the Z-axis, and coordinated feeding of the X- and Z-axes. It has automatic grinding wheel dressing and automatic compensation for dressing volume.
(4) It is equipped with a handheld electronic handwheel. The electronic handwheel can adjust the manual feed of the X- and Z-axes.
(5) It is equipped with a three-color light device that can display the working status of the machine tool.
