Spŕndle Temperature Rise Test Runout of Whee1 Spindle Conical Surface
To assure spindle temperature - App1y a test indicator to the rear, rise below 10 C, the spindle middle and front points of the conical is tested under a no load surface of the wheel spindle, and condition for a minimum rotate the wheel spindle, the variation of 8 hours. The spindle is shall be under run throughout its entire speed range whìle being continuously monitored by a
thermograph.

Parallelism and Squareness of Wheel Spindle

Spindle Dynamic Balancing Test

The spindle of each machine is calibrated by a portable precision dynamic vibration measuring device. The final amplitude of spindle vibration shall be under or less.

Centerline to Table Surface

Place a cylinder gauge on the table, swing the test indicator which is fixed on the wheel spindle, and obtain the readings of the indicator when the table is at its right, middle, and left positions. The parallelism and the squareness are under.

Parallelism of Table Surface to Table

Cross Transverse Shifting of Steel Roller Bearings

Attach the base of a test indicator to the wheel head. Touch the stylus of the indicator to the table surface. Traverse the table in and out. The indicator variation shall be within.

The steel roller bearings used in all three axes guideways are sieved by an automatic machine which assures the tolerance of the bearings within mm.

Parallelism of Table Surface to Table Longitudinal Movement

Attach the base of a test indicator to the wheel head. Touch the stylus of the indicator to the table surface. Move the table left to right and reverse, the indicator variation shall be within m.

Control Station

The control station can be adjusted to a comfortable position for the operator. All switches, buttons, LEDs, indicating lamps, and displays are ergonomically positioned providing friendly operation.

Crossfeed Transmission

The saddle incorporates a specially designed play-compensating feed nut and hardened and ground leadscrew, resulting in the elimination of backlash. Therefore, high accuracy results can be obtained during operations such as plunge grinding.

Saddle Guideway System

The guideway system of the saddle is composed of specially designed preloaded needle roller bearings and hardened and ground slide rails. The roller bearings consist of independent leading and trailing bearings. Trailing bearings support the vertical load, and preloaded leading bearings assure accuracy of the cross movement. The combination of these two features provides excellent longevity and low friction, stick-slip-free movement.

Micro Crossfeed Device

The micro crossfeed device consists of a worm and worm gear. Turn the lever clockwise to engage the worm and worm gear for fine adjustment at increments of mm. Once the worm and worm gear are engaged, the cross power feed motor and the cross handwheel are automatically engaged.

Process Quality Control

To ensure the quality, accuracy, and longevity of our products, every technician follows step-by-step quality control procedures from casting to final inspection.

Column Inspection

The column is placed on a granite surface plate, and the perpendicularity of the guideways is inspected with a precision electro-indicator.

Wheelhead Guideways Inspection

The parallelism of the wheelhead guideways is inspected with a precision electro-indicator. These and numerous other tests throughout production help maintain and improve the quality of CHEVALIER grinders.

Automatic Precision Surface Grinding Machine

The highly advanced AD11 series of automatic precision surface grinding machines are a result of the ongoing and extensive research and development program at CHEVALIER. In addition to improved accuracies, quality, and machine life, the overall design of the machine incorporates ergonomics; all operating handwheels, levers, stroke setting devices, and the pendant control panel are arranged to allow ease of operation. Therefore, working efficiency is increased.

AC Servo Vertical Drive

The wheelhead traveling on a preloaded linear guideway system is driven by a hardened and ground leadscrew and an AC servo motor, providing high torque, speed, and accurate positioning with a minimum increment of manual pulse generator (MPG) standard for easy operation.

3 Axes Needle Roller Slideway

All three axes guideway rails are composed of S55C steel that is normalized and then hardened by high-frequency induction. The guideways are HRC 60-64 after heat treating. Precision roller bearings run through a sieve to select exactly matched sets, which are then preloaded between the linear guideway to provide a guideway system that will ensure excellent accuracy and precise positioning with stick-slip-free movement.

Crossfeed Speed Control Option

The saddle continuous movement speed is controlled by a frequency converter for obtaining a better grinding surface finish and dressing grinding wheel from the table.
