Main Specifications

Manufacturer: Okamoto

Model: ACC-450DXA

Year: 2001

Machine Type: Precision Hydraulic Surface Grinder / Surface Grinding Machine

Grinding Capacity

Maximum Grindable Surface: Approx. 450 x 150mm

Table Working Area: Approx. 510 x 150mm

Longitudinal Travel: Approx. 530mm

Cross Travel: Approx. 175mm

Distance from Grinding Wheel to Table: Approx. 60–510mm

The generous longitudinal movement relative to the 450mm grinding length allows the wheel to clear the component during the grinding cycle.

Grinding Wheel & Spindle

Grinding Wheel Diameter: Approx. 205mm

Grinding Wheel Peripheral Speed: Approx. 2,400m/min

Grinding Spindle Motor: Approx. 1.5kW

The spindle arrangement is designed for precision surface grinding where good finish, flatness and dimensional accuracy are required.

Additional Drive Motors

Hydraulic Pump Motor: Approx. 0.75kW

Crossfeed Motor: Approx. 0.75kW

Grinding Head Up/Down Motor: Approx. 0.4kW

DXA Automatic Grinding Cycle

The ACC-450DXA version is designed to provide an automatic grinding cycle, making it suitable for repetitive precision surface grinding operations.

The DX-series design incorporates features aimed at both rough and finish grinding, including:

• Automatic grinding-cycle capability
• Hydraulic longitudinal table movement
• Powered crossfeed
• Powered vertical grinding-head movement
• Coarse and fine vertical feed
• Precision feed adjustment
• Robust saddle-type construction
• Hand-finished precision guideways
• Automatic lubrication system

These features make the ACC-450DXA suitable for both one-off toolroom work and repetitive component grinding.

Precision Okamoto Construction

The ACC-450 DX series was designed as a compact precision surface grinder with a rigid machine base and column.

Its double-V guideway arrangement and precision slideway construction are intended to provide stable table movement and maintain grinding accuracy over long-term use.

This type of machine is well suited to workshops requiring greater precision and productivity than a basic manual surface grinder while retaining straightforward operation.

Spare Grinding Wheels Included

The machine is supplied with a selection of spare grinding wheels.

Having additional wheels available allows the purchaser to select different abrasive types and specifications to suit individual materials, grinding operations and surface-finish requirements.

Approximate Machine Dimensions

Overall Length: Approx. 1,940mm

Overall Width: Approx. 1,317mm

Overall Height: Approx. 2,129mm

Machine Weight: Approx. 1,250kg

What is an Okamoto ACC-450DXA?

The Okamoto ACC-450DXA is a hydraulic precision surface grinding machine designed to produce accurate flat surfaces and close dimensional tolerances.

The workpiece is normally secured to the machine table while the grinding wheel removes controlled amounts of material as the table passes beneath the wheel.

Unlike a basic manual surface grinder, the DXA configuration provides an automatic grinding cycle, making it particularly useful where repeated passes, controlled feed and consistent finished dimensions are required.

With approximately 450 x 150mm grinding capacity, the ACC-450DXA provides a compact footprint while retaining useful capacity for general precision engineering work.
