+Saddle Moving Surface Grinder SGA Series
Saddle type surface grinder is a kind of surface grinder which adopts cross arm linkage and saddle guide type structure. Its main feature is that the transverse traveling track is guided by the guide rail, and the table is close to the grinding head, which is suitable for medium and small surface grinding and processing as well as curved and difficult-to-machine workpieces. This series machine is divided into AHR and AHD series. The AHR type is driven by ordinary motor in vertical direction, while the AHD type is driven by servo motor in vertical direction, and PLC control can realize automatic grinding.
- Max. longitudinal travel: 1130mm
- Cross travel: 450mm
- Max. distance: 560mm
- Table size: 406*1020mm

Features
- The machine adopts cross-pallet layout, and the transverse guideway is coated with PTFE soft tape.
- The table moves with a closed hydraulic system, and the front and rear feeds can be manually fed or automatically intermittently fed by a motor-driven screw.
- The up and down movement of the grinding head can be accomplished by using the lifting motor for fast lifting (AHR) or servo motor for fast lifting and automatic feeding (AHD), or manually.
- Adopting high-precision sliding screw and high-strength cast iron base parts, the grinding head spindle adopts precision angular contact rolling bearings, high rigidity sleeve structure, the overall quality of the machine tool is stable, and the operation is smooth.
Applications
- Saddle type moving surface grinding machine can grind workpieces made of steel, cast iron, non-ferrous metals and other materials.
- It is widely used in medical equipment, electronic industry, machinery manufacturing, military and aerospace industry, automobile and motorcycle parts and mold industry, etc.
