The machine offers a maximum grindable ID of approximately 700 mm, a maximum workpiece OD of 750 mm, and can handle deep internal grinding up to approximately 500 mm according to the supplied machine information.

Equipped with TOYOMATIC CNC control, Mitsubishi GOT1000 HMI, in-process measuring capability and a 6-wheel grinding tool system, this used vertical grinder is particularly suitable for large spindle components, bearing parts, hydraulic components and other precision industrial workpieces.

Key Machine Specifications

Main Features

High-Precision Vertical Grinding Structure

The T-183C uses a vertical grinding configuration designed to provide strong support for large and heavy workpieces. Its guideway and spindle arrangement helps reduce the influence of workpiece weight during precision bore grinding.

Large-Bore Grinding Capacity

With a grindable internal diameter of up to approximately Ø700 mm and a maximum workpiece outside diameter of approximately Ø750 mm, the machine is suitable for large industrial components that are difficult to process on conventional horizontal internal grinders.

Deep Internal Bore Grinding

The supplied machine configuration is capable of approximately 500 mm deep internal grinding, making it suitable for long bores, spindle housings and deep cylindrical components.

In-Process Measuring Capability

The machine is equipped with an online / in-process inspection system, allowing dimensional feedback during the grinding cycle and helping operators maintain consistent bore accuracy.

TOYOMATIC CNC Control

The machine uses the TOYOMATIC control platform together with a Mitsubishi GOT1000 graphic operation terminal for machine setup, grinding cycle control, dressing and machining monitoring.

Multiple Grinding Wheel Tooling

The machine is equipped with six grinding wheel/tool positions, allowing different grinding wheels to be prepared for multiple bore sizes, materials or machining processes.

Suitable Applications

The used TOYO T-183C vertical internal grinder is suitable for precision internal diameter grinding and related finishing operations on medium-to-large industrial components.

Typical applications include:

• Hydraulic cylinder blocks and hydraulic valve bodies
• Large bearing housings and bearing rings
• Machine-tool spindle sleeves
• Precision spindle components
• Gear internal bores
• Large transmission components
• Aerospace engine and transmission components
• Automotive and commercial vehicle parts
• Compressor housings and compressor components
• Precision pump components
• Machine-tool structural components
• Large iron and steel bearing seats
• Wind-power and energy-industry components
• Precision molds and tooling components
• Powder metallurgy components
• High-accuracy mechanical parts requiring large or deep internal bores

It is especially attractive for manufacturers producing large precision bores where roundness, straightness and surface finish are critical.

Why Consider This Used TOYO T-183C?

For manufacturers that require a large-capacity precision internal grinder, purchasing a well-maintained used Japanese machine can significantly reduce capital investment compared with purchasing new equipment.

This TOYO T-183C combines:

Ø700 mm internal grinding capacity + Ø750 mm workpiece capacity + approximately 500 mm deep-bore capability + in-process gauging + CNC control.

It can be a practical solution for companies expanding precision grinding capacity while keeping equipment investment under control.
