Chevalier Manual Surface Grinders
SP Series Super Precision Surface and Form Grinders
- These models have all the features of the Chevalier M Series Grinders but with heavier and more rigid construction.
Features:
- Table traverses on linear ball bearings and D2 (SKD11) hardened and ground guideways.
- Reinforced ribbed column with hardened and ground guideway system.
- Elevating and crossfeed leadscrews are hardened and ground.
- Saddle travels on Turcite-B coated and hand-scraped Double-V guideways.
- Vertical handwheel at waist level.
- 0.001mm (0.000050") vertical micro-feed device.
- Permanently lubricated and sealed cartridge-type spindle uses two pairs of Class 7(P4) angular contact ball bearings.
- 2HP dynamically balanced spindle motor.
- Automatic lubrication system.
- Meehanite castings.
- A mirror surface can be accomplished on these machines accurately and efficiently due to machine construction features and the specially designed V3 grade spindle motor that provide excellent rigidity and stability.

M Series Standard Tool Room Surface Grinders
Features:
- This high-precision surface grinder has been specially developed to help manufacturers with a wide range of needs.
- The tool cabinet in the machine base is specially designed for operator's convenience (618M).
- The interlock between electrical cabinet door and power supply is established to ensure safe operation.
- The maximum distance from the table surface to the spindle centerline is 450mm (177"), which provides more clearance for grinding.
- The manual grinders feature a spring-loadedtype table travel-stops that dampen the over travel caused by abnormal operations.
- The optimum span of double-V crossfeed guideways is designed based on bending moment, kinematics and supporting force.
- All essential castings are high-grade Meehanite cast iron which the stress relieved has been done through annealing to eliminate internal stress.
- With the impressive stiffness and stability of its castings, this machine is suitable for both precision surface grinding and form grinding.
- This grinder is offered with one-year warranty for mechanical and electrical parts.
