SV35X – VERTICAL HONING MACHINE WITH SERVO X AXIS, SERVO SPINDLE, AND TOOL DRIVESHAFT GRIPPER (STEP & REPEAT CAPABILITY- IN LINE BORES)- WORK HOLDING OPTIONAL

Depending on the model, the SV-35 series includes such features as:

• Constant crosshatch finish is maintained throughout the bore from top to bottom, with no rollover, via the synchronized servo spindle and stroker mechanisms. 
• Step and repeat functionality provides automatic bore-to-bore operation with servo X-axis and new GH LF series tooling.
• Tool protection at both top and bottom of the bore.
• Rugged cast iron column.
• Intuitive, easy-to-use Sunnen2 controls with a large 396 mm (15.6 in.) color touch screen.
• Proven servo ball screw stroking mechanism.
• CE compliant safety system standard on all models.
• All models feature Beckhoff industrial controls with Sunnen2 software.
• For applications not requiring a high level of automation there are models offered with value-priced features such as manual column movement.
• Backed by Sunnen’s best in the industry 3-year parts and labor warranty and our extensive global field service support team.

There are three new standard SV-35 models with varying options assuring the right fit for virtually any applications.  Depending on the model, the SV-35 series includes such features as:

• Variable speed 50-600 rpm, 3.4 kW (4.55 hp) servo spindle motor is powerful enough to drive two-stage, metal-bond, diamond and CBN abrasives for short cycle times with high accuracy and minimal labor. 
• Heavy-duty cast iron column.
• The front loading design and weight capacity of up to 600 kg (1325 lbs.), including fixture, combine for versatility in honing a wide range of parts.
• PC-controlled with a large 396 mm (15.6 in.) color touch screen that is rugged and eliminates cumbersome buttons that collect oil, dirt and grime. The swiveling operator panel can be adjusted for viewing from a variety of positions.
• Servo or manual driven X-axis allows left/right positioning of the column with 813 mm (32 in.) range.
• Servo rotary tool feed system can be used with two-stage hone heads to complete roughing and finishing without stone changes for faster processing times. Rough-to-finish changeover is four times faster than previous models.
• Proven 3.5 kW (4.7 hp) servo ball screw stroking system allows for increased flexibility and performance.
• Heavy-duty welded base for durability.
• Standard LED work area lighting.
• Standard 206 liter (55 gallon) internal coolant system is equipped with two canister filters on the side of the machine, for ease of maintenance, and provides increased coolant filtration for precise surface finish. Includes filter status indicator.
• Standard state-of-the-art CE compliant safety features include interlocked sliding front panel, side and rear panels, front mounted light curtain, safety PLC, and safe limited setup speeds. 
• Optional OPC-UA interface allows access for remote process monitoring.
• Standard PC uninterruptible power supply (UPS) eliminates unsafe shutdown of control system and ensures a safe start-up. 

The new Sunnen2 controls on the SV-35 allow for a consistent crosshatch surface finish from the top to the bottom of the bore. 

• Windows®-based PC touch screen control system – coupled with servo tool feed provides optimum process control with ease of set-up.
• Intuitive touch screen – ensures new machine operators are quickly trained. Setup time is minimized.
• Crosshatch control – Enter desired crosshatch angle and the Sunnen2 controls automatically adjust spindle and stroker speeds continuously to achieve constant crosshatch angle throughout the bore.
• Full bore profile display – projects a real-time display of the bore cross section that simplifies removing taper from the bore … allows user to dwell in the exact position as long as necessary where bore is visually smaller – a Sunnen innovation.
• Tool Protection – automatically checks the top and bottom of the bore prior to starting the cycle.
• Rough and finish cycles – rough cycle removes stock fast and can be set to automatically switch to finish cycle for optimum bore geometry and for the desired crosshatch angle.
• Standard programmable Auto Dwell for unattended operation – the machine automatically dwells in the tightest part of the bore – top, middle or bottom. 
• Bore Oversize Setup – allows for fast setup for engine rebuilders in standard oversizes (Example: .010 in., .020 in., .030 in.).
• Screen selectable languages – English, German, Spanish and Chinese are included.
