Precision surface and profile grinding machine

To avoid effects of heat expansion and vibration, the hydraulic unit is isolated from the main unit. For the purpose of long lifetime and maintenance free operation, oil lubrication with automatic lubrication is applied to the guide and slide way. Combination of both scraped V-V slide way and low friction Turcite assure accurate grinding for life. All castings exhibit high static and dynamic stiffness and excellent damping qualities.

Manual precision surface grinding machine

Having a grinding length of 350 mm and a cross travel of 150 mm the Linear 350B is ideally suited for the toolroom. It features a high level of standard equipment to ensure easy handling and the manual control allows quick and precise small part production.

• Machine base made of cast iron
• Vibration -reducing construction
• Table slideway with linear rollers

Okamoto makes a wide range of surface grinding machines from small manual surface grinders to large double column CNC surface grinders.

• Small manual surface grinder with capacity 350x150mm
• Easy to use conventional grinders with capacity 500x200 up to 1000x500mm.
• Small sized CNC surface profile grinding machines with capacity from 200x100.
• Medium sized CNC surface grinding machines with capacity 600x400 up to 1500x700mm.
• Large sized double column surface grinding machines with capacity 1000x800 up to 10000x4000mm.

These machines are available with different control types:

• An enhanced version of the well proven and reliable Okamoto control provides a fully automatic grinding operation. Front panel switches have been completely removed and integrated into the control panel to guaranty easy set up and control. Feedrates and feed change points are set and adjusted at any time by potentiometers.

• Touch Screen control with colour graphics incorporating digital position indicator for each axes and easy-to-use pictorial software, mounted in swivelling operating control panel. Until now complex tasks in precision grinding depended very much on the experience of a skilled operator. The development of the new Okamoto iQ touch screen control and its easy to use software allows everyone to achieve impressive results. The breakdown of complex tasks into simple basic operations, enables even unskilled operators to use the machine with maximum efficiency.

Precision rotary table grinding machine

Horizontal spindle CNC rotary table grinding machine. This machine has a portal design, with moving column crossfeed. The table is in constant rotary motion, which adapts automatically to the changing grinding diameter. Furthermore, the table can be pivoted ± 1° for calibration.

At the Hannover EMO 2023 in Hall 11 Stand E65, Okamoto proudly presents a new addition to the ACC-CAiQ Series. The ACC-CAiQ range with sizes from 600x400 up to 1000x600 has been extended with the addition of 3 new larger heavy duty sizes, the PSG-126CAiQ with a size of 1200x600, the PSG-127CAiQ with a size of 1200x700, and the PSG-157CAiQ with a size of 1500x700.
The new larger models benefit from an extremely robust heavy duty main machine casting with a new moving column design that features a high-level column cross slide that further increases the rigidity and strength of the machine. Starting with the 1.2m size, these larger machines are also delivered with a heavy-duty wheel-head together with a 15kW spindle motor and a Ø510mm grinding wheel. Despite having a longer table stroke, the cycle time is reduced thanks to a ball-screw table drive with 40m/min feed rate.
All CAiQ Series machines benefit from an extremely rigid main casting with fully supported slide ways to guarantee the highest stability and accuracy. Double V hand scraped table slideway ensure that the lubrication oil is perfectly distributed to ensure a flat surface and straight table movement.
The touch screen Fanuc control, that has proven so popular with existing users of the CAiQ Series, has been further developed and made even quicker and easier to set both in production and in tool room environments. The new Fanuc control offers an even faster response, with a larger high-definition touch screen with sharper graphics. The Okamoto graphical touch screen user interface featured on the iQ range of surface grinders is undoubtedly the best control on the market.
Graphical representation of common user-friendly grind patterns and wheel shapes are quickly set-up directly on the touch screen view panel with the help of the iQ function. The iQ function can automatically set the optimal grinding conditions, simply by entering the grinding wheel mesh / grit size.
Until now complex tasks in precision grinding depended very much on the experience of a skilled operator. The development of the Okamoto iQ touch screen control and it’s easy to use software, coupled with the inherent mechanical accuracy of the column moving design, allows even unskilled operators to use the machine with maximum efficiency & precision.
The attractive 2 tone colour and ergonomic design of the fully enclosed table cover, with interlocked sliding door, allows modern large volume high pressure coolant systems to be used, to increase productivity whilst keeping the workshop environment clean.
