OIG-200S Shoe Center Design NC INTERNAL GRINDER Special Purpose Grinder for Bearing Inner Dia. & Groove --------------------------------------------------------------------- The Internal Grinder for bearing inner dia. and groove is specially applied for bearing grinding. The workpiece loading, unloading, and the work head movement could operate at the same time in order to shorten the time for setting & adjustment. The machine could equip with a vibration feeder or workpiece arranging device in order to have auto-loading control. Machine equipped with Palmary developed conversational control panel (Mitsubishi PLC) for easy operation. The customer could choose to use a CNC controller as an optional.

The machine bed is manufactured from high-quality Meehanite cast iron, heat-treated, and stress relieved for outstanding stability and without deformation. 1. Main Structure of the CNC cylindrical grinder, when in combination with angle control of spindle by C axis (built-in spindle motor), is capable of grinding various special-shaped workpieces. 2. The feed axis is driven by a linear motor and equipped with close loop control optical scale to reach high precision. 3. The working spindle carried with precision angle decoder, high resolution of angle control. 4. Retaining various functions of CNC cylindrical grinder, and applicable to angle and speed control.

Based on PALMARY's tradition of "Pursuing Quality Perfection", combined with human engineering design and peak performance concepts, each machine fully reflects PALMARY's unmatched design and technique. Honeycomb-type machine structure assures the best possible rigidity and stability. The machine bed is manufactured from high-quality Meehanite cast iron, heat-treated, and stress relieved for outstanding stability and without deformation.

1. The design of honeycomb Tubular type machine bed and cross guideway structure for improving the higher rigidity and stability. 2. Equipped with max. 6 no. grinding wheels for different diameter or accuracy requirements. 3. For end face grinding application, the wheel spindle can swivel to 22.5 degrees for easy grinding. 4. The coolant flow has an isolation design from the machine bed and can reduce the heat deformation and dirt contamination on the bed.

The new CNC internal Grinding Machine from PALMARY features optimal structural design, and an elegant appearance combined with advanced CNC control. The all new series will bring internal grinding technology into a new era. The structural parts of the machine are manufactured from high quality cast iron for deformation-free performance year after year. The entire machine is precision built throughout to guarantee the best possible grinding accuracy you can find anywhere. More detail: www.palmary.com

The new and miniaturized CNC internal Grinding Machine from PALMARY features a build-in spindles design, a man-made mineral machine bed for more stability, minimizing its space, and an elegant appearance combined with advanced CNC control and interactive screen operation. The all-new series will bring internal grinding technology into a new era. 1. The high rigidity and stable man-made mineral machine bed could provide the smooth machining requirement and be the basis of accuracy. 2. The high efficiency bearing built-in spindles are used on both grinding wheel spindle & work spindle which offer the high accuracies grinding performance. 3. The clients’ factory land capacity was increased for the machine has a small machine bed design which only same as B1 paper size. Further, it’s easy to equip the automatic loading system. 4. Both X & Z axes equip with linear servo motors which provide high-speed grinding activity and shorten the cycle time. Further, the digital readouts are put on both axes for high-speed precision efficiency.

The machine structure is strengthened with the same design as a heavy-duty cylindrical grinder. The enlarged hydrostatic wheel spindle construction could equip max. 125 mm width grinding wheel for plunge grinding application. 1. The machine structure is strengthened with the same design as a heavy-duty cylindrical grinder. 2. The enlarged hydrostatic wheel spindle construction could equip max. 125 mm width grinding wheel for plunge grinding application. 3. The large fully splash guard is designed for more interior space use. 4. The taper fine adjustment tailstock is a standard accessory and easy to adjust the taper if required. 5. The variable frequency grinding wheel speed control could reach max. 60 M/s cutting speed. 6. All the slides are hydrostatically designed for smooth movement while the grinding process. 7. The optional accessories such as the OD measuring system are possible to equip for the client's use. 8. The CNC conversational controller is easy to operate.

Super rigid structure, stable without deformation. The double support grinding wheel spindle design features high-speed operation to boost grinding performance. Computer numerical control from 1 ~ 6 axes satisfies requests for customized specifications. Fitted with a wider wheel, suitable for efficient mass production. 1. The double support bearing type spindles offer even grinding force on the contact surface. During the grinding process, the stress is even on both ends of the spindle to avoid taper-shaped workpieces. 2. Adjustable R.W. worm shaft eliminates the gap and increases transmission efficiency and lifetime. 3. The one "V" & one flat feeding slide design reinforce the feeding stability. The entire feeding slide is hand scrapped to reduce friction and to increase the accuracy of jog movement. 4. The oil mist lubrication device is arranged for grinding wheel spindle lubrication, which also helps to clean and constant temperature control.

With a highly experienced design and manufacturing background in centerless grinders, PALMARY presents the new bearing type CNC centerless grinder. It is designed and engineered to offer the operational performance & higher accuracy you've come to expect. 1. High grinding accuracy and rigidity design for max. 6 axes CNC control bearing spindle type grinder for wide range application. 2. The machine has the grinding wheel spindle single bearing holding type equipped with super precision cylindrical roller bearings making centerless grinding easier and more accurate than ever before. 3. The best configuration for the machine bed and structural support ribs make the grinding accuracies more stable and reach a higher accuracy level.
