Overview

The SH-1224-2A is a two-axis automatic surface grinder — longitudinal and cross feed both run under power, so the operator sets the pass and the machine executes it. That’s what separates a production grinder from a toolroom machine: consistent finish across the whole surface, without depending on how evenly someone cranks a handwheel.

The way construction is where the accuracy lives. Double longitudinal “V” ways and cross “V” ways on both table and saddle, hand scraped and Turcite coated. Turcite is a low-friction bearing material bonded to the sliding surface; combined with hand scraping it gives smooth, chatter-free travel that stays accurate as the machine wears. The castings are annealed for stability, so the machine holds its geometry over years rather than settling out of tolerance.

The hydraulic table carries over-travel protection and preset speed control. You dial a table feed rate anywhere from 6 to 83 feet per minute and get that exact rate every time the table is engaged — no drift between setups, no re-finding the right speed for a repeat job. Auto crossfeed runs in both intermittent and continuous mode, so you can step over between passes or feed continuously for a finishing sweep.

Twelve by twenty-four inches of table with a 20-inch center height handles die plates, mold bases, fixture surfaces, and machine ways. A 3 HP spindle turns a 14-inch wheel at 1,720 RPM.

Manuals and documentation

Ordering and freight

Ships by freight and needs rigging rather than a curbside drop. Send us your delivery address, dock situation, and access details and we will build a complete landed quote covering freight and placement.

A magnetic chuck is required and is not included. The grinder does not function without one. Tell us your work and we will spec the right chuck — fine pole for small precision parts, standard pole for general work — and quote it with the machine.

Power: wired 220V or 440V, specify at order.

Upgrade path: the optional NC spindle downfeed adds ballscrew and servo control of the third axis, turning this into a fully automatic three-axis grinder. Worth considering if you run repeat parts to a set stock removal.
