Smart Honing Lifts Business for Aerospace Hydraulic Pumps

The work envelope of the honing machine shows air-bearing index table in foreground, robot to left, honing spindle and tool upper center, and air gage right. 
This second generation machining business is using a new technology that makes a 60 millionths tolerance look generous. No kidding.

GMTA Announces a New Hire and Plans for an Open House

Schminke has worked for the past 12 years at the German partner to GMTA, Diskus.
GMTA named Maik Schminke the manager of controls engineering and programming and announced plans for an open house. 

Sunnen Honing System Offers Increased Part Capacity and Stroker Torque

Ideal for flow-tube weld cleanup, the HTA hone is ergonomically designed with a moveable operator station and a modular work holding system for rapid setups.
Ideal for bore resurfacing, the Sunnen HTA hone is PLC controlled, handles parts up to 13.5 ft long, 21 in diameter and 8000 lbs.

Perfect Holes in Hard Material – Made Easy

The SV-­560 features an intuitive interface and advanced Windows-­based PC control to simplify the honing process and allow anyone withmult-axis experience to run the machine like an expert.(Click on photo to enlarge it)
Exotic materials specialist Damen Carbide Tool Co. expands its holemaking capability and business base with honing capacity to 9 in diameter and a 60 in stroke length using hones from Sunnen.

Diamonds are a Block’s Best Friend for Honing

Large-Part Honing Machine for Job Shops, Repair Facilities

The SV-20 honing system from Sunnen.
The SV-20 honing system from Sunnen Products is the first competitively priced large-part machine for job-shop part production with a true linear, vertical, servo-stroking system to produce precision bore geometries on compressors, oilfield components, automotive/truck blocks and similar parts.

Smarter Tool Feed Enhances Production Honing

Piston pumps used in hydraulic flight control systems have clearances of 0.005 mm between moving parts, requiring ultra-precise bore size, roundness, straightness, etc. Here are piston pump bodies in a multi-spindle honing machine equipped with air gaging stations between spindles. Controlled-Force honing, which works in concert with the machine's standard rate-feed system, functions like cruise control to maintain the optimum cutting load on the honing abrasive throughout a cycle, irrespective of the incoming part's hardness, geometry or size variation.(Click on photo to enlarge it)
This new tool feed technology from Sunnen servo-controls the force in the honing tool feed system to maintain the optimum cutting load on the honing abrasive throughout a cycle, irrespective of the incoming part's hardness, geometry or size variation.
