Machine Description

Used 2014 Lapmaster International DSG 720 Double Side Fine Grinding Machine available for sale.

The Lapmaster DSG720 is a precision double-sided fine grinding machine designed to process both parallel faces of components simultaneously. This type of machine is suited to applications requiring close control of flatness, parallelism, thickness and surface finish.

This machine is equipped with 720mm outside-diameter grinding wheels, a 6-carrier workholding system, independently controlled upper and lower grinding wheel speeds and a Siemens SIMATIC touchscreen control.

A separate coolant filtration system is also included.

Important Condition Note

The top grinding plate / upper grinding wheel assembly is damaged and requires replacement.

The machine is therefore being offered with this known defect clearly disclosed. Prospective purchasers should allow for the replacement of the top grinding plate before returning the machine to normal production use.

Main Specifications

Manufacturer: Lapmaster International

Model: DSG 720

Year: 2014

Machine Type: Double Side Fine Grinding Machine / Double-Sided Grinding Machine

Grinding System

Grinding Wheel Outside Diameter: Approx. 720mm

Grinding Wheel Inside Diameter: Approx. 320mm

Wheel Size: Ø720 x Ø320mm

Number of Workpiece Carriers: 6

Upper Grinding Wheel Speed: 0–130 rpm

Lower Grinding Wheel Speed: 0–130 rpm

Inner Pin Ring Speed: 0–100 rpm

The double-sided grinding arrangement allows both sides of suitable components to be processed simultaneously, helping achieve consistent component thickness and parallelism.

Electrical Specifications

Operating Voltage: AC 380V, 3 Phase

Frequency: 50Hz

Installed Power: Approx. 18kW

Current: Approx. 50A

Pneumatic Requirements

Normal Air Supply: Approx. 5–6 kg/cm² / 0.5–0.6MPa

Minimum Working Pressure: Approx. 4 kg/cm² / 0.4MPa

A suitable clean and regulated compressed-air supply will therefore be required for operation.

Siemens SIMATIC Touchscreen Control

The machine is equipped with a Siemens SIMATIC touchscreen operator control.

The control arrangement provides operator access to the machine's grinding functions and process settings while the separate hard buttons provide important machine controls.

The control panel includes functions for items such as:

• Touchscreen machine operation
• Upper grinding plate movement
• Outer pin ring up/down
• Coolant operation
• Inner ring jog/indexing
• Cycle start
• Stop and reset
• Emergency stop
• Two-hand safety control

Coolant Filtration System Included

The Lapmaster DSG 720 is supplied with a separate coolant filtration system.

Coolant filtration is particularly important in precision fine grinding because removal of grinding debris and contaminants helps maintain:

• Consistent grinding performance
• Improved surface finish
• Stable process conditions
• Longer abrasive wheel life
• Reduced recirculation of grinding particles

The filtration equipment supplied with the machine can be seen in the accompanying photographs.

Approximate Machine Dimensions

Machine Width: Approx. 1,800mm

Machine Depth: Approx. 1,500mm

Machine Height: Approx. 2,550mm

Net Machine Weight: Approx. 2,800kg

The installation layout indicates that additional floor space is required for the coolant filtration equipment, loading area, electrical cabinet and operator access.

Transport and installation dimensions should therefore be confirmed prior to collection.

Typical Applications

A Lapmaster double-sided fine grinding machine can be used for precision finishing of components requiring close dimensional and geometric control, including suitable:

• Precision engineering components
• Bearing components
• Mechanical seals
• Valve components
• Automotive components
• Hydraulic components
• Pump components

• General high-precision production parts

Exact suitability will depend on component material, dimensions, tooling, carriers and grinding wheel specification.

What is a Lapmaster DSG 720?

The Lapmaster DSG 720 is an industrial double-side fine grinding machine designed to grind two opposing faces of a component during the same machining cycle.

Double-sided fine grinding is commonly used where conventional surface grinding or lapping cannot provide the required combination of production rate, parallelism, flatness and controlled component thickness.

Components are positioned in carriers between an upper and lower abrasive grinding wheel. The relative motion of the grinding wheels, carriers and pin rings produces controlled material removal from both sides of the component.

This makes the DSG720 particularly relevant to manufacturers searching for a double disc grinder, double-sided surface grinder, fine grinding machine or precision lapping alternative.

Machine Condition

The machine is offered as a used 2014 Lapmaster DSG 720 complete with control system and coolant filtration equipment.

Please note:

The top grinding plate is damaged and requires replacement.

The machine should therefore be inspected by the purchaser and the cost and availability of the replacement upper grinding plate established before returning the machine to production.

This condition is being clearly disclosed as part of the sale.
