Reasons for surface burns on workpieces after CNC cylindrical grinding machine processing

2025-04-10

The causes of surface burns on workpieces after machining with CNC cylindrical grinders.1、 Improper control of feed rate. The solution to this problem is to reduce the feed rate. A larger feed rate can be used at the beginning of CNC cylindrical grinder production, and relatively smaller feed rates can be used in the later stages to reduce the depth of grinding.2、 Wrong selection of grinding wheel. Grinding wheels with small particle size, soft hardness, and loose structure should be selected. Use large hole grinding wheels to keep the grinding wheel in sharp conditions, and choose suitable cutting fluids with good lubrication to reduce friction between the abrasive particles and the workpiece.3、 Friction between the grinding wheel and the workpiece's contact surface causes problems. At this point, the contact surface between the grinding wheel and the workpiece can be reduced to contro...

Maintenance steps for CNC cylindrical grinder

2025-04-10

What are the maintenance steps for CNC cylindrical grinding machines?1： Remove the spindle, polish and grind the spindle neck, increase the surface roughness of the spindle, and make the spindle roughness of the CNC cylindrical grinder reach Ra0.05um.2： The lubricating oil for the static pressure oil tank is composed of 30% 20 # mechanical oil and 70% kerosene. When the oil tank is added, the pressure is adjusted to around 1.5Mpa using an overflow valve, and the oil pressure entering the oil chamber is adjusted to around 1.0-0.6Mpa using a feedback throttle. After the lubricating oil enters the bearing oil chamber, check whether there is a phenomenon of light and sinking on one side after locking. The grinding wheel spindle should float in the middle of the bearing and be adjusted properly by gently rotating it by hand.3： Before maintenance, it is necessary to use a dial gauge to detect...

Characteristics of various components of CNC cylindrical grinder

2025-04-10

1. Bed and worktableThe bed of the CNC cylindrical grinder adopts large circular holes and shark fin shaped rib plates. After long-term use, the machine tool has good dynamic and static stiffness. The workbench can be divided into upper and lower surfaces for grinding conical surfaces. The guide rails for the bed and worktable are made of plastic coated rails, which have a low coefficient of friction. The worktable is directly driven by a servo motor to move the ball screw, ensuring smooth and solid movement.2. Grinding wheel holderThe linear speed of the grinding wheel is less than 35m/s, with high grinding efficiency. The grinding head bearing is a large angle three tile dynamic pressure bearing, with high rotational accuracy. The movement of the grinding wheel rack is directly dragged by servo motors and ball screws, with a resolution of 0.0005mm.3. HeadframeThe rotation of the headstock dial is driven b...

Inspection of CNC cylindrical grinder before use

2025-04-10

The common feature of CNC grinders is that the cutting force is relatively small, so it is necessary to improve the grinding force of the cutting tools and conduct regular maintenance of the CNC grinder. Simultaneously understanding the maintenance process of CNC cylindrical grinders plays an important role in increasing their efficiency and achieving high-speed and effective grinding.Firstly, it is necessary to inspect the spindle of the grinding wheel holder of the CNC cylindrical grinder and adjust the clearance between the bearing shells to ensure that there are no data errors during machine use.Next, check the spindle and replace the oil on the grinding wheel holder spindle. If the main engine oil is not replaced in time during long-term operation, it will affect the operation of the equipment and cause energy loss faults. The hydraulic oil of the CNC cylindrical grinder system should also be replaced ...
