Adjustment wheel drive system

The driving motor of the adjusting wheel spindle adopts servo motor. Speed10~250rpmIt can be set arbitrarily and can be easily adjusted to the maximum speed during grinding. When the outer diameter of the adjustment wheel changes, the same linear speed can be maintained to grind out the product.

The servo motor is cleverly designed and installed on the adjusting wheel box and is directly driven by a timing belt. It can interact with the adjusting wheel during grinding.boxSamestep rotationangle. Make sure the two pulleys are always parallel. Overcome the old centerless grinder chain drivetimeMany adverse effects caused by included angles，Avoid changing chains frequentlyandZipper spring.

  Dressing device

The dressing seat is made of special alloy cast iron and undergoes multiple treatments including tempering and vibration to ensure stability and wear resistance. The dressing slide is designed with a dovetail shape and a widened track surface. It is precision manual scraping after one-time molding and grinding processing. It can be used with hydraulic reciprocating trimming or servo motor for molding trimming.

sliding mechanism

The upper slide rail is designed with a dove-shaped groove structure and hasPositive or negative5The function of degree rotation makes adjustment simple and quick. The lower sliding plate adopts doubleVType slide rail and double wedge-shaped auxiliary rail, the structure is stable and can avoid the intrusion of cutting fluid, making it easy to maintain. Both the upper and lower slides can be equipped with manual and automatic fine-tuning of the feed, with an accuracy of up to0.001MM .

  Hydrostatic spindle

  The high-precision hydrostatic spindle is designed and developed for the workstation of Academician Fu Xincheng. Static pressure withstands working pressure25 MPa, the main shaft is suspended in the hydrostatic oil-bearing film, achieving high precision, high rigidity, high speed and low friction. The use of high-pressure oil film to carry heavy loads and heavy cutting can effectively reduce spindle wear and maintain spindle operation accuracy.

Hydrostatic guide

  static pressure trackDesigned and developed products for Academician Fu Xincheng’s workstation and successfully applied for invention. The track is designed as a fully enclosed hydrostatic suspension track with small hole throttling. The entire track is suspended in a high-pressure oil film when working, and the friction coefficient is less than0.001. There is no contact between the working surfaces when the track is running, and there is no wear and long service life. The static pressure oil film has strong rigidity and its thickness is almost not affected by speed. It will not crawl even at extremely low speeds and can achieve 0.0001MM feed setting.

BType adjusting wheel rolling bearing spindle

BThe main shaft of the adjusting wheel rolling bearing is designed as a double support structure.FAGDouble row roller bearings and angular contact bearings. Even during low operating speeds and heavy cutting, the spindle can rotate with ultra-high precision and maintain rigidity. Ensure the true roundness and cylindricity of the ground products.

CNC system and software

CNC centerless grinder selectionCNCThe control system uses precision ball screws and servo motors for numerical control. It can realize the automatic feeding of the upper and lower rails according to the grinding process, and realize automatic dressing and automatic compensation of various shapes of the grinding wheel and adjusting wheel. It greatly improves the centerless grinder's processing ability for complex-shaped workpieces and reduces the difficulty of manual operation. A variety of automatic loading and unloading and automatic detection solutions are available to choose from, realizing fully automatic processing and production of high-precision parts.

Centerless grinder grinding software professionally developed by Fuxincheng2.0version, matchCNCThe control system provides a conversational operation interface. All settings can be completed with simple data input, making the operation simple and convenient.

CNCDressing device

CNCThe dressing device provides an accurate and fast dressing solution for processing multi-step and complex-shaped workpieces. Both the grinding wheel and the adjusting wheel can be trimmed into various shapes required according to the requirements of the grinding process. Diamond pens, butterfly rollers, and shaping rollers can be used as trimming tools.
